Introduction. A non-carious lesion (NCL) is the loss of hard dental tissue on the neck, tuberculum and incisal edges of the teeth. Interest in clinical presence and in unclear etiology of these lesions allows for their future prevention and treatment. Objective. The aim of the study was to determine presence and clinical characteristics of NCLs and dentine hypersensitivity (DH), as well as their possible risk factors in children, in the population of the city of Novi Sad. Methods. A total of 55 subjects were included in the present study, aged between three and 18 years. Each subject completed a structured questionnaire related to the etiological factors, and all teeth of each subject were examined by two independent clinical dentists to determine NCLs and DH. In the case of small children, their parents or guardians filled out the questionnaire. Teeth with NCLs and DH were diagnosed according to the Basic Erosive Wear Examination (BEWE) index and by a blast of air according to Schiff and Hypersensitivity Index. The review was carried out by inspection and probing. Results. The data were analyzed by clinical examination and comparison of the answers to the questionnaires. We observed an increased presence of non-caries lesions on primary teeth, compared to permanent teeth, with a statistically significant difference (?2=3.86, df=1, p=0.04). The changes were observed in 82 teeth, and were most frequent on the canine deciduous teeth (65%) and canine permanent teeth (51%). BEWE index was 10-11% to 92-100% in permanent, and 51-57% in deciduous teeth. Majority of patients with primary teeth (89.36%) did not respond to air stimulus, while most patients with permanent teeth (74.29%) did not react to Schiff Index. In the estimate of sensitivity, the respondents reported hypersensitivity on 6.38% of the deciduous teeth and 22.86% of the permanent teeth. Comparison of etiology factors did not reveal a direct link with the appearance of NCLs. Conclusion. Research has shown that despite the lack of subjective symptoms, these lesions have distinct clinical characteristics. The fact that they occur even in deciduous dentition justifies the need for further investigations.

Objective: To assess the association of occlusal forces and brushing with non-carious cervical lesions (NCCL). Methodology: It was a Cross-sectional study. The study was conducted in Dental clinics, Department of Surgery, The Aga Khan University Hospital Karachi. The study duration was from 1st January 2009 to 28th Feb 2009. Ninety patients visiting dental clinic were examined clinically. Presence of Non- carious cervical lesions, broken restorations, fractured cusps, presence of occlusal facets, brushing habits, Para functional habits were assessed. All the relevant information and clinical examination were collected on a structured Performa and was analyzed using SPSS version 14.0. . Chi square X2 test was applied to assess association among different categorical variables. Result: Twenty three (26%) females and 67 (74%) males were included in the study. Thirty five of them (38.9%) were found to have Non-carious cervical lesions. Presence of NCCL has no association with gender (P value 0.458). A significant association was found between NCCL and teeth sensitivity (P value 0.002).The association between use of hard tooth brush and Non-carious cervical lesions was found significant (P value <0.001). However the association among Non-carious cervical lesions and fractured cups, broken restoration, teeth grinding, jaw clenching, pan chalia chewing and frequency of teeth brushing were insignificant. Conclusion: Hard tooth brushing and teeth sensitivity have significant association with Non-carious cervical lesions. The role of occlusal wear in the formation of NCCL is not significant.

The high prevalence of non-carious manifestations in patients with celiac disease is described by numerous authors, who are considered as a diagnostic key to atypical forms of celiac disease. The manifestations closely associated with celiac disease include: defects in tooth enamel, pathological tooth abrasion, as a violation of the mineralization of dental crowns, and morphofunctional defects in the hard tissues of the teeth.Materials and methods. We examined 45 patients aged 23 to 36 years with a diagnosis of celiac disease, established on the basis of the results of clinical anamnestic, genetic, instrumental studies, morphological study of a biopsy specimen of the intestinal mucosa.Result. Examination of the dentition of the patients showed that 100% of the examined had pathological abrasion of tooth enamel. Crowded teeth were found in 32 patients. Partial symmetric congenital adentia was diagnosed in 5 patients.Conclusion. The revealed dentoalveolar anomalies can be attributed to oral manifestations of celiac disease, which is a diagnostic criterion for suspected disease.

Background: Dental caries is one of the most prevalent diseases. Its detection and management should start with a comprehensive treatment plan, with the goals of the elimination of cariogenic bacteria, the reduction of plaque acidogenicity, the encouragement of tooth remineralization, and the repair of damaged teeth. Objectives: The aim of this paper was to review the literature regarding the latest updates on the diagnosis and management approaches of non-cavitated carious dental lesions. Methods: Studies regarding the diagnosis and management of non-cavitated carious dental lesions were included. Results: The subclinical non-cavitated carious lesion might progress to an early enamel lesion, develop into an established dentin lesion, or sometimes end up with a lesion reaching the pulp. The detection and management of caries should be patient-centered, risk-based, and evidence-supported, and should consider the dentists’ expertise and the patients’ needs and preferences. The visual-tactile and radiographic detection of non-cavitated carious lesions are greatly helped by the advances of non-invasive detection tools such as DIAGNOdent, fiber-optic transillumination, quantitative light-induced fluorescence, and DIAGNOcam. Conclusion: Accordingly, non-cavitated carious lesions can be arrested by several non-invasive techniques, which are preferred over the invasive options. The clinicians can use sealants plus fluoride varnish on occlusal surfaces, fluoride varnish or resin infiltration on proximal surfaces, and resin infiltration,fluoride gel, or varnish alone on facial or lingual surfaces to manage non-cavitated carious lesions.

Bacground/Aim. Environmental lead (Pb) pollution is a global problem. Hard dental tissue is capable of accumulating lead and other hard metals from the environment. The aim of this study was to investigate any correlation between the concentration of lead in teeth extracted from inhabitants of Pancevo and Belgrade, Serbia, belonging to different age groups and occurrence of tooth loss, caries and non-carious lesions. Methods. A total of 160 volunteers were chosen consecutively from Pancevo (the experimental group) and Belgrade (the control group) and divided into 5 age subgroups of 32 subjects each. Clinical examination consisted of caries and hard dental tissue diagnostics. The Decayed Missing Filled Teeth (DMFT) Index and Significant Caries Index were calculated. Extracted teeth were freed of any organic residue by UV digestion and subjected to voltammetric analysis for the content of lead. Results. The average DMFT scores in Pancevo (20.41) were higher than in Belgrade (16.52); in the patients aged 31-40 and 41-50 years the difference was significant (p < 0.05) and highly significant in the patients aged 51-60 (23.69 vs 18.5, p < 0.01). Non-carious lesions were diagnosed in 71 (44%) patients from Pancevo and 39 (24%) patients from Belgrade. The concentrations of Pb in extracted teeth in all the groups from Pancevo were statistically significantly (p < 0.05) higher than in all the groups from Belgrade. In the patients from Pancevo correlations between Pb concentration in extracted teeth and the number of extracted teeth, the number of carious lesions and the number of non-carious lesions showed a statistical significance (p < 0.001, p < 0.01 and p < 0.001, respectively). Conclusion. According to correlations between lead concentration and the number of extracted teeth, number of carious lesions and non-carious lesions found in the patients living in Pancevo, one possible cause of tooth loss and hard dental tissue damage could be a long-term environmental exposure to lead.

Full textAbstract:
Background and Objectives: The therapeutic management of carious lesions remains a significant focus for researchers, given their persistently high prevalence despite being largely preventable. This study aimed to compare the effectiveness of a composite resin-based sealant material in halting extended non-cavitated dentin carious lesions when used therapeutically versus preventively on caries-free teeth over a period of twelve months. Materials and Methods: out of the 236 children examined, 45 were excluded from the study due to non-compliance with the inclusion criteria. Thus, the study included 191 children aged 10–12 years, and 764 molars in total. Results: among these molars, 171 were caries-free (ICDAS II code 0), forming the Control group, while 180 molars were classified with an ICDAS II score of 3, forming the Study group. All molars were sealed and evaluated at 6- and 12-month follow-up intervals. Both intervals revealed statistically significant differences (p < 0.05) in sealant retention and carious lesion development between sound (ICDAS code 0) and decayed (ICDAS code 3) teeth. Conclusions: the findings did not support the effectiveness of sealants in halting non-cavitated dentin carious lesions classified as ICDAS II with code 3 compared to their preventive application in sound teeth classified as ICDAS II with code 0.

Full textAbstract:
Introduction: Non-carious lesions are caused as a result of tooth surface loss. Several categories of tooth surface loss exist, including erosion, attrition, abrasion and abfraction. Numerous factors, such as bruxism, clenching, disease, dietary considerations, lifestyle choices, improper tooth brushing, abrasive dentrifices, craniofacial complex, iatrogenic dentistry and ageing might contribute to this problem. It can be challenging to identify the cause, but it is feasible by observing the pattern of tooth surface loss on the teeth, and it is essential for treatment planning to avoid failure. Prevention, tooth remineralization and active treatment by repairing the affected teeth are all methods of managing this process. Treatment options include minimally invasive and adhesive dentistry to full mouth rehabilitation, and restoring the lost vertical height. Case Report: A 45-year-old female patient reported to the Department of Conservative Dentistry and Endodontics with a chief complaint of sensitivity in the upper front teeth for the past 2 months. The clinical examination showed abrasion on the buccal surface of teeth 13 and 23 with dentin exposure. And also, abfraction with respect to 14. No signs of mobility or pain on percussion. Conclusion: The steps of problem identification, diagnosis, etiological factor removal or treatment, and, if necessary, restoration, are components of treating non-caries lesions. The restorative treatment must be considered for dentin hypersensitivity and for the re-establishing of dental esthetics.

The worldwide incidence of ECC was found to be 1.76 billion. If left untreated, these carious lesions have high possibility to progress into oro-facial swellings. The purpose of this study was to evaluate the carious teeth in primary dentition, which causes oro-facial swelling. This observational study is carried out by observing the oro-facial infection in children and describing the associated carious teeth using GV Black's classification, ICDAS Criteria for carious teeth and also categorizing the caries index of the patient using dmft index. A total of 189 case sheets were reviewed, and cross-verification was done by photographs. Among the 189 case sheets, a total of 70 cases were selected after proper review. Out of 70 patients, 51 patients had Class 1 carious lesion, and 19 had Class 2 carious lesion all the teeth were categorized under ICDAS score 5 and 6, the mean dmft score was 8.64. Class 1 carious lesions with visible dentin were most commonly associated with Oro-facial Swelling in children. The carious teeth, which were ICDAS-6, were treated by extraction and which were ICDAS-5, were rendered pulp therapy.

The therapy of non-caries cervical lesions is an important problem in restorative dentistry, for the ambiguous aetiology, clinical diagnoses and for the selection of restorative procedure. Aim: The aim of this work was to clinically check the efficiency of non-caries cervical lesions restoration depending on materials used for restorative fillings. Materials and methods: Clinical researches covered 62 teeth of different morphology group at the patients of both gender and of different age. The restoration of gingival lesions, with no previous preparation, was done with composite adhesive system SINGLE BOND/Valux Plus (3M) (30 teeth) and with campomer DYRACT AO (Dentsplay) (32 teeth). The fillings were estimated on the checkups which took place on 3,6 and12 months applying modified criteria according to Ridge and Cvar. Results: The acquired results showed that after 3 to 6 months there were no changes at none of examined parameters and all the fillings got maximal mark A. 12 months latter, in the two cases with composite filling, the marginal adaptation got the mark B (607%). The marginal adaptation at two teeth restored with compomers got the mark B (6.3%) Postoperative sensitiveness phenomenon, marginal discoloration and secondary caries weren?t registered in none of the cases after the observation period of 12 months. Conclusion: For the restoration of non-caries cervical lesions, composite materials with suitable adhesive system and the new generation of compomers could be used. .

Objective: To examine the dispersal of NCCLs (non-carious cervical lesions) by tooth type. This research also aims to explore NCCLs’ prevalence in those patients who go through orthodontic surgery and the possible factors linked with it. Study design: A cross-sectional study Place and Duration: This study was conducted at Pakistan Medical Center Hyderabad from August 2021 to August 2022. Methodology: Overall, 162 individuals were involved in this research. Data from the patients were collected before and after the orthodontic surgery. The data include age, gender, number of sessions activated, facial pattern, retreatment, compensatory treatment, and angle’s malocclusion. Lateral intraoral pictures of every patient were taken from the left, right, and front. These pictures were clicked to see whether NCCLs are present or absent in every tooth and to evaluate the dispersal of non-carious cervical lesions in the teeth of every individual. To evaluate the relationship between each variable and NCCLs, Poisson regression analysis (multivariate and bivariate) with robust variance was used. The confidence interval was at 95% and significant p-value was less than 0.05. Results: The prevalence of NCCLs before orthodontic surgery was 23.01% and the prevalence of non-carious cervical lesions after orthodontic surgery was 31.09%. The most affected teeth were premolars along with incisors, first molars, and canines. It was found after the statistical analysis that the factor that affected the prevalence ratio was age. If orthodontic surgery was performed in adulthood, NCCLs were more prevalent. Conclusion: It was concluded that the most affected teeth by NCCLs were premolars. Moreover, age seems to influence the increasing prevalence of non-carious cervical lesions in those participants who go through orthodontic surgery in their adulthood. Keywords: premolars, non-carious cervical lesions, teeth, orthodontic surgery

Abstract Introduction. White spot lesions are early signs of demineralization, which may or may not lead to the development of caries. An inactive white spot lesion might act as an arrested dental caries and affect the esthetic appearance by displaying a milky white color. These lesions need a non-invasive or a minimally invasive treatment. One of the materials taken into consideration in treating these lesions is ICON, a biomimetic material that infiltrates the white spots and can reestablish the esthetic function. The aim of the current study was to evaluate the esthetic efficacy of a minimally invasive technique and a relatively new product on the dental market, ICON, in the treatment of different non-cavitated carious lesions. Case presentation. A 14-year-old patient presented to the dental clinic with asymptomatic, non-cavitating lesions on the cervical aspect of all permanent teeth. The lesions were diagnosed as incipient caries on the buccal, occlusal, and palatal surfaces of the teeth, and the proposed treatment to arrest their progression and improve the esthetic appearance was the use of the ICON infiltration technique. Conclusion. The ICON resin infiltration treatment increased esthetics, visibly diminishing the appearance of non-cavitating carious lesions.

A barrier to providing sealants is concern about inadvertently sealing over caries. This meta-analysis examined the effectiveness of sealants in preventing caries progression. We searched electronic databases for comparative studies examining caries progression in sealed permanent teeth. We used a random-effects model to estimate percentage reduction in the probability of caries progression in sealed vs. unsealed carious teeth. Six studies, including 4 randomized-controlled trials (RCT) judged to be of fair quality, were included in the analysis (384 persons, 840 teeth, and 1090 surfaces). The median annual percentage of non-cavitated lesions progressing was 2.6% for sealed and 12.6% for unsealed carious teeth. The summary prevented fraction for RCT was 71.3% (95%CI: 52.8%–82.5, no heterogeneity) up to 5 years after placement. Despite variation among studies in design and conduct, sensitivity analysis found the effect to be consistent in size and direction. Sealing non-cavitated caries in permanent teeth is effective in reducing caries progression.

Human teeth have become a prominent source of DNA for human forensic identification as their biological structure is highly resistant to extreme conditions. Previous forensic identification was mainly dependent on the pulp and the other hard tissues of intact teeth. However, there is high likelihood that only carious teeth can be available for forensic analysis. This study aimed to validate the use of the carious part of the teeth for forensic identification and to compare two DNA extraction methods-the operative technique with the cervical cut technique for human identification using STR typing. The reliability of STR markers in carious part of the teeth was evaluated in 120 carious teeth (60 dental pulp and 60 dentinal carious tissues, respectively) with considerable coverage of gender type and age range to avoid false exclusions. The study was performed on genuine data set where samples have been extracted by proficient dentist during the treatment operation and collected for further analysis. Complete DNA was extracted and the corresponding human identification profile was obtained using the GoldenEye™DNA ID system 20A kit. The operative technique showed a conservative approach to the sampling of carious tissues and allowed safe access to collect carious tissues, whereas the cervical cut technique permitted access to the root canals and complete sampling of the pulp tissues. The findings indicated that there was no significant association between the cervical cut and operative cut techniques ( p = 0.165). In addition, there was no statistically significant association between the various teeth types and the obtained profiles observed. The operative technique, by drilling holes on the defected surface of carious human teeth and gentle hand excavation of carious tissues, was indicated to be very efficient, preserving, time-saving, and cost-effective in the recovery of human DNA from carious teeth. The result gives new insights that the carious tissues of human carious teeth might be as valid as the healthy teeth for forensic human identification.

Full textAbstract:
Non-carious cervical lesions (NCCLs) represent a form of tooth wear, characterized by the irreversible loss of dental hard tissues at the enamel–cement junction, without the involvement of caries and dental trauma. The aim of this study was to highlight the morphological elements of NCCLs via their stereomicroscopic examination and to confirm the role of this examination in the diagnosis of early lesions. In addition, the association between the morphological aspects identified during the stereomicroscopic examination of NCCLs and their etiological factors was determined. For this study, extracted teeth with NCCLs were examined with a stereomicroscope. The morphological aspects of NCCLs were evaluated at magnifications up to 75×. In wedge-shaped NCCLs, the stereomicroscopic examination allowed the identification and measurement of scratches, furrows and cracks. In saucer-shaped NCCLs, the stereomicroscopic examination highlighted the smooth appearance of the walls. The presented study highlighted the role of stereomicroscopic examination in the assessment of NCCL morphology and in their early diagnosis. The study confirmed, in particular, the role of occlusal overloads and tooth brushing in determining the morphology of NCCLs.

Non-carious cervical lesions (NCCLs) are considered the irreversible losses of dental hard tissues at the cemento–enamel junction, in the absence of acute trauma and dental caries. The aim of this study was to highlight the presence of NCCLs in cervical areas based on specific macroscopic aspects in order to establish their clinical form, size and location and to confirm the role of optical coherence tomography (OCT) examination in the early diagnosis of these lesions. For this study, 52 extracted teeth were used, which did not have endodontic treatments, fillings or carious lesions in the cervical area. All teeth were examined macroscopically and OCT was used to evaluate the degree of occlusal wear, the presence and clinical form of NCCLs. Most NCCLs were identified on the buccal surfaces of the premolars. The most frequently encountered clinical form was the wedge-shaped form, with a radicular location. NCCLs present most frequently in the wedge-shaped form. Teeth that presented several NCCLs were identified. The OCT examination is an adjunct method to evaluate the clinical forms of NCCL.

Studies have been carried out on 166 children of three age groups (6,9 and 12 years) with carious lesions of the teeth of different intensity who have been living since birth in areas with а deficiency of essential macro-and microelements,in particular, fluorine and iodine in environmental objects. The oral fluid of 46 healthy children of the appropriate age, served as control without pathological changes of the hard tissues of the teeth. The results of our research have demonstrated a significant decrease (p<0,05) of the concentrations of calcium and inorganic phosphorus in the oral fluid of pupils in case of dental carious lesions compared with healthy children, respectively by 20,87 % and 13,13 %. The lowest values of investigated parameters were observed in children of all age groups with the dental carious process of the third degree of activity. A reduction of the levels of calcium and inorganic phosphorus is an evidence of abated processes of mineralization, which contributes to the onset and progression of a carious lesion of the teeth. A study of the electrolyte composition of the oral fluid in this cohort of children may serve for determining risk groups, an early diagnosis, a timely treatment and prevention of a carious lesion of the teeth.

The article presents an analysis of the results of a study of the incidence of non-carious tooth lesions in adults with type 2 diabetes, including when they were under dynamic observation by a dentist for 2.5-3 years. It was found that in patients with type 2 diabetes mellitus non-carious lesions of the teeth (49.51%) were significantly more likely to occur than in people in the control group (29.13%). At the same time, it has been shown that in people with type 2 diabetes, a significant improvement in dental health can be achieved due to their being under dynamic supervision by a dentist with a 2-time visit during the year. This allows to reduce the incidence of non-carious tooth damage in type 2 diabetes mellitus by 17.7%, mainly due to the constantly implemented secondary and tertiary dental prophylaxis, rational and competent use of individual oral care products by patients, and also due to dental orthopedic treatment.

Full textAbstract:
The aim of this study was to determine the effects of 38% silver diamine fluoride (SDF) on carious lesions of human deciduous teeth. Ten extracted deciduous incisors with caries were collected and treated with SDF. After the treatment, the teeth were sectioned through the center of the carious lesion. The extent of sliver precipitation was examined using quantitative backscattered electron scanning electron microscopy (qBSE-SEM), energy-dispersive X-ray spectroscopy (EDX), and micro-computed tomography (micro-CT). The qBSE-SEM images revealed that the silver particles could penetrate through the pellicle complex, along with the rod sheaths into the demineralized enamel rods and the dentinal tubules, and form silver-enriched barriers surrounding the carious lesions at depths up to 2,490.2 μm (mean 744.7 ± 448.7 μm) within the dentinal tubules of the carious lesions, but less likely in the sound enamel. The EDX spectrum analysis revealed that carbon, oxygen, phosphorus, chlorine, silver, and calcium were the main elements detected in the lesions treated with SDF. Additionally, sodium, magnesium, aluminum, silicon, zinc, sulfur, and fluorine were detected as the minor elements within the SDF precipitation “zone.” The micro-CT analysis further showed that in the deep cavitated lesions, the silver precipitation could be observed in the pulp chamber. These findings provide new evidence defining the SDF mode of action for arresting caries and suggest that the application of a highly concentrated SDF solution on deciduous teeth should be used with caution for various carious lesions.

Summary Caries infiltration is a novel technique that brings out immediate esthetic improvement in the opacity of the white spot lesions. Light-induced fluorescence method is a modern caries diagnostic method. In this study SoproLife camera (Acteon, France) was applied for diagnosing and follow-up of the results. The aims of this in vivo study are to test the role of light-induced fluorescence method (SoploLife camera) in the diagnosis of non-cavitated smooth surfaces carious lesions (ICDAS codes 1 and 2) of primary and permanent teeth and in the follow-up period immediately after application, 6 months and 1 year after applying ICON material (DMG). Teeth: n = 90; primary teeth: 6 kids; n = 40 teeth; permanent teeth: 6 patients; n = 50 teeth. Visual examination by ICDAS without probe, dry for 10 s with 3-in-1 syringe using lightening; SoproLife camera (450 nm), digital photos. LIF method applied with SoproLife camera (Diagnostic mode with day light and blue light) is more accurate than visual examination only when applied for single tooth diagnose. Moreover, LIF method for single tooth is more accurate in following up the effect of non-operative treatment of smooth surfaces lesions than using digital images. ICON is a material that stops the progression of non-cavitated smooth surfaces carious lesions in both primary and permanent teeth and make the aesthetic result better up to 1 year following the procedure.

Dental sealants are excellent means to prevent pits and fissure caries. Nowadays, the application of sealants is extended to therapeutic use in arresting non-cavitated carious lesions. This relatively new concept still lacks evidence to support its routine use. The aim of this study was to evaluate the effectiveness of a resin-based sealant applied on first permanent molars with carious lesions (ICDAS 1–3), in comparison with its effectiveness when applied on sound surfaces (ICDAS 0). Included in the study were 114 children aged between six and eight years old, with a high caries risk (according to the CAMBRA system), with all four permanent molars erupted and with deep pits and fissures. A total number of 407 molars were sealed and assessed. A total of 49 were excluded (they had caries, which according to the ICDAS II classification were classified with code 4–6 or had older sealants or fillings). Out of these 407 molars, 213 were sound (code 0) and 194 had caries lesions as follows: 56 teeth classified as code 1, 79 teeth classified as code 2, and 59 teeth classified as code 3 according to the ICDAS II classification. The retention of the sealant and carious lesions were assessed clinically at 6, 12, 18, and 24 months. Regarding sealant retention, a statistically significant difference (p < 0.05) among the two types of sealed teeth, sound (ICDAS 0) and decayed (ICDAS 3), showed at 18- and 24-month follow-up intervals. Regarding caries lesions, a statistically significant difference (p < 0.05) showed between sound (ICDAS 0) and decayed (ICDAS 3) molars at 24-month follow-up. Our study results supported the resin-based sealant effectiveness in arresting incipient carious lesions, which according to the ICDAS II classification have received codes 1 and 2 but did not support sealant effectiveness in arresting caries lesions classified according to the same classification with code 3.

Full textAbstract:
One of the aims in the clinical operative management of dental carious lesions is to remove selectively the highly infected and structurally denatured dentine tissue, while retaining the deeper, repairable affected and intact, healthy tissues for long-term mechanical strength. The present study examined the correlation of chemical functional groups and the microhardness through the different depths of a carious lesion using Raman spectroscopy and Knoop microhardness testing. The null hypothesis investigated was that there was no correlation between Raman peak ratios (amide I : phosphate ν1 ) and equivalent Knoop microhardness measurements. Ten freshly extracted human permanent teeth with carious dentine lesions were sectioned and examined using high-resolution Raman microscopy. The ratio of absorbency at the amide I and phosphate bands were calculated from 139 scan points through the depth of the lesions and correlated with 139 juxtaposed Knoop microhardness indentations. The results indicated a high correlation ( p < 0.01) between the peak ratio and the equivalent Knoop hardness within carious dentine lesions. This study concluded that Raman spectroscopy can be used as a non-invasive analytical technology for in vitro studies to discriminate the hardness of carious dentine layers using the peak ratio as an alternative to the invasive, mechanical Knoop hardness test.

Full textAbstract:
The goal of nonrestorative or non- and microinvasive caries treatment (fluoride- and nonfluoride-based interventions) is to manage the caries disease process at a lesion level and minimize the loss of sound tooth structure. The purpose of this systematic review and network meta-analysis was to summarize the available evidence on nonrestorative treatments for the outcomes of 1) arrest or reversal of noncavitated and cavitated carious lesions on primary and permanent teeth and 2) adverse events. We included parallel and split-mouth randomized controlled trials where patients were followed for any length of time. Studies were identified with MEDLINE and Embase via Ovid, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews. Pairs of reviewers independently conducted the selection of studies, data extraction, risk-of-bias assessments, and assessment of the certainty in the evidence with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Data were synthesized with a random effects model and a frequentist approach. Forty-four trials (48 reports) were eligible, which included 7,378 participants and assessed the effect of 22 interventions in arresting or reversing noncavitated or cavitated carious lesions. Four network meta-analyses suggested that sealants + 5% sodium fluoride (NaF) varnish, resin infiltration + 5% NaF varnish, and 5,000-ppm F (1.1% NaF) toothpaste or gel were the most effective for arresting or reversing noncavitated occlusal, approximal, and noncavitated and cavitated root carious lesions on primary and/or permanent teeth, respectively (low- to moderate-certainty evidence). Study-level data indicated that 5% NaF varnish was the most effective for arresting or reversing noncavitated facial/lingual carious lesions (low certainty) and that 38% silver diamine fluoride solution applied biannually was the most effective for arresting advanced cavitated carious lesions on any coronal surface (moderate to high certainty). Preventing the onset of caries is the ultimate goal of a caries management plan. However, if the disease is present, there is a variety of effective interventions to treat carious lesions nonrestoratively.

Full textAbstract:
Concurrently, dentistry has embraced technological advancements, incorporating digital imaging techniques in various applications [1]. This crossover study aimed to assess digital dental photography imaging as a diagnostic tool for detecting incipient pits and fissure carious lesions in permanent teeth and its correlations with traditional visual examination according to ICDAS II. Direct intraoral clinical examinations were conducted by two AEGD residents and two calibrated restorative consultants trained in the ICDAS II grading system. A total of 34 occlusal surfaces of premolars and molars were examined. Only healthy teeth, enamel hypomineralization, and non-cavitated carious surfaces were included. Non-carious hard tissue defects, fissure sealants, and direct and indirect restorations were excluded. The digital photographs were obtained by two examiners and then blindly assessed in a presentation room using a large screen. The actual scoring of pit and fissure carious lesions in 18 extracted premolar teeth was examined under a clinical microscope based on the downer histological examination. Sensitivity and positive predictive value were highest in photographic examination compared with visual in three observers, while specificity and negative predictive value were equal between visual and photographic examination. From the survey, we compared differences in caries and non-caries detection between PAADI Instructors and PAADI Residents using the Mann-Whitney U test. Residents are more likely to overestimate the results compared with the instructors (P value < 0.05). The Az values for the different examination methods compared with the gold standard (histologic examination) were calculated. The Az values of the two examiners (Consultant 2 and Resident 1) were highest for the visual examination, while it was highest for the photographic examination for Consultant 1 and Resident 2. Visual clinical examination should be the standard for detecting incipient occlusal pit and fissure carious lesions, and digital photographic imaging is a valid diagnostic tool as well.

Background and Aim: Non-carious cervical lesions (NCCLs) are defined as any deterioration of the tooth tissue in terms of abrasion, composition, and erosion during normal and/or pathological function. The present study aimed to assess different etiological causes of cervical lesions among patients without caries in the population of Lahore, Pakistan. Materials and Methods: A cross-sectional analytical study was carried out on 62 patients aged 16-60 years in the Department of Dentistry of a Tertiary Care Hospital of Lahore, Pakistan from July 2022 to December 2022. Patients were categorized into two groups: Group-I (Non-carious dental lesions patients) and Group-II (without non-carious dental lesions patients). All the patients underwent clinical examinations and answered a questionnaire which included inquiries related to oral hygiene, personal impressions, eating habits, teeth appearance and functionality, and it also emphasized on the different etiologies of non-carious dental lesions.Results: Out of the total 62 patients, the study and the control groups consisted of 38 (61.3%) and 24 (38.7%) patients respectively. Age-wise distribution of the patients was as follows: 19 (30.6%) in 16-30 years, 12 (19.4%) in 31-45 years, and 31 (50%) in 46-60 years.

The removal of carious dentin is one of the fundamental procedures in restorative dentistry. Managing deep carious lesions in vital teeth is challenging and crucial as any adversity caused during the treatment might lead to pulp exposure. Treatment for deep carious lesions is empirical, involving a great deal of inconsistency. Therefore, this comprehensive review aims to provide a detailed description of two treatment protocols for deep carious lesions involving indirect pulp capping versus stepwise caries excavation.

Objetive: To evaluate microleakage of composite resins (CR) placed over different cavitary liners after managing deep caries lesions through selective removal of soft carious tissue to soft dentin (SRCT-S). Material and Methods: Fifty four human teeth were collected for microleakage testing. Each assay comprised ICDAS 5 or ICDAS 6 carious lesions and sound teeth for controls. Sound teeth were prepared with cavities that mirrored the carious teeth cavities, which were prepared with SRCT-S. Sound and carious teeth were further randomly assigned to one of the three experimental groups: Group A: universal adhesive (UA) + CR, Group B: glass ionomer cement liner + UA + CR, and Group C: calcium hydroxide + UA+ CR. Occlusal microleakage (OM) and cervical microleakage (CM) was classified within one of 5 depth categories. ANOVA and Chi-square tests were computed (p<0.05). Results: OM and CM were similarly distributed across subgroups (p>0.05). All Group C samples with carious lesions presented some degree of microleakage. However, no statistically significant differences were observed between groups and within each group (p>0.05). Conclusion: Teeth restored with CR after SRCT-S using calcium hydroxide as a liner material seem to exhibit higher microleakage than those restored using glass ionomer or UA alone. Further clinical research is needed to deepen these findings. Clinical significance: The application of calcium hydroxide as a liner under a composite resin may reduce the longevity of a restoration after performing selective or partial removal of carious tissues. Clinicians should rethink the need of using calcium hydroxide for this application, albeit the lack of clinical evidence.

Full textAbstract:
For an ORCA/EFCD consensus, this review systematically assessed available evidence regarding interventions performed and materials used to manage dentin carious lesions in primary teeth. A search for systematic reviews (SRs) and randomized clinical trials (RCTs) with a follow-up of at least 12 months after intervention was performed in PubMed, LILACS, BBO, and the Cochrane Library. The risk of bias tool from the Cochrane Collaboration and the PRISMA Statement were used for assessment of the included studies. From 101 screened articles, 2 SRs and 5 RCTs, which assessed the effectiveness of interventions in terms of pulp vitality and success of restoration, and 10 SRs and 1 RCT assessing the success of restorative materials were included. For treatments involving no carious tissue removal, the Hall technique showed lower treatment failure for approximal carious lesions compared to complete caries removal (CCR) and filling. For the treatment of deep carious lesions, techniques involving selective caries removal (SCR) showed a reduction in the incidence of pulp exposure. However, the benefit of SCR over CCR in terms of pulp symptoms or restoration success/failure was not confirmed. Regarding restorative materials, preformed metal crowns (PMCs) used to restore multisurface lesions showed the highest success rates compared to other restorative materials (amalgam, composite resin, glass ionomer cement, and compomer), and in the long term (12–48 months) these were also less likely to fail. There is limited evidence supporting the use of PMCs to restore carious lesions with single cavities. Among nonrestorative options, silver diammine fluoride was significantly more effective in arresting caries than other treatments for treating active carious lesions of different depths. Considerable heterogeneity and bias risk were observed in the included studies. Although heterogeneity observed among the studies was substantial, the trends were similar. In conclusion, less invasive caries approaches involving selective or no caries removal seem advantageous in comparison to CCR for patients presenting with vital, symptomless, carious dentin lesions in primary teeth. There is evidence in favor of PMCs for restoring multisurface carious lesions in primary molars.

Resin infiltration of initial caries lesions is a novel method of caries therapy. However, it has some limitations. Therefore, further experimental studies are needed to improve resin infiltration. It was the aim of this investigation to study resin infiltra-tion into different experimental carious lesions. Caries-free extracted human molars and premolars were demineralized for 3, 6, 9 and 12 days and infiltrated with resin. Prior to infiltration, the teeth were incubated with sodium fluorescein. After em-bedding, serial sections were cut through the experimental lesions, and the penetration of the resin was measured with fluo-rescence microscopy. Two infiltrated teeth from each time interval were not embedded and cut. Infiltration of the resin was then studied with EDS element analysis. The results showed that with increasing demineralization time, the lesion expansion was also increasing, and the resin infiltration was always almost complete. From these results it can be concluded that artifi-cial standardized caries-like lesions are suitable for experimental studies of resin infiltration.

Objective: The prevalence of non-carious cervical lesions (NCCLs) has increased in the recent years, especially in the elderly population. The successful prevention and treatment of those lesions requires an understanding of the biomechanics of aged teeth. Considering the importance of such aspect, the impact of the age-related dentin deposition on the stress distribution of NCCLs was evaluated by means of finite element analysis. Material and Methods: A 2-dimensional model of a sound maxillary first premolar was created using CAD software. Two tooth geometries (sound, aged) and two lesion shapes (wedge, saucer) were simulated to the model. The mesh was built with 35,000 triangle and square elements of 0.1 mm in length. All tissues were considered isotropic, homogeneous and linear. Occlusal surfaces were loaded with 300 N for simulating normal chewing forces. The stress distribution was analyzed by a color scale and by the maximum principal stress at the cavosurface line angle. Results: The aged models presented lower stress concentration in the overall system in comparison to sound models. The sharp angle of wedge shaped lesions promoted higher stress concentration at the center of cavosurface angle, favoring the lesions progression. Conclusion: Considering the limitations of the current methodology, it is possible to conclude that aged tooth is a more compact structure that can better respond to stress loadings. This protective intrinsic mechanism should be considered when adopting preventive and restorative measures for NCCLs for the elderly.KeywordsAging; Finite element analysis; Non-carious; Cervical lesions.

Full textAbstract:
Recently, researchers note an increase in the prevalence of non-carious lesions of solid dental tissues. The forms of non-carious lesions of teeth are described: erosion and abrasion, wedge-shaped defects and erosion, which were previously practically not met.
 Increasing the life expectancy and maintaining natural teeth also led to the fact that clinicians often began to meet with patients with increased erosion of teeth.
 Study of the mechanism of adherence of glass-like cements to dentin is very important. In our case, the adhesion of our cements to dentin and enamelabs of acid protrusion, in our opinion, is provided by two mechanisms. The first of these is based on the fact that carboxylate groups of the macromolecules of polyacrylic acid are capable of forming chelating compounds with calcium, in particular calcium hydroxyapatite dentin and enamel.
 The second possible mechanism of communication is based on the affinity of polycarboxylic acids to nitrogen of protein molecules, in particular, collagen, which is manifested by the absorption of polyacrylic acid on collagen dentin.

Full textAbstract:
The contemporary approach for operative caries management emphasizes personalized interventions for each patient, dependent upon the individual’s caries susceptibility/risk, the stage of the carious lesion and its activity. The clinician’s challenge is to optimize the extent of cavity preparation and the choice of dental restorative biomaterials, appreciating the benefits offered by ion-releasing restorative materials. There is a growing application of bioactive/bio-interactive materials in minimally invasive operative dentistry, as they may help with tissue recovery by ion release. In case of moderate or extensive occlusal cavitation, the clinical criteria include the individual caries susceptibility and carious lesion activity. In high caries risk cases, ion-releasing biomaterials (IRB) can be used, as well as for active carious lesions. In proximal lesions, the clinical criteria include the individual caries susceptibility, the lesion activity and presence of cavities with little or no enamel at the gingival margin. This article aims to discuss the restorative ion-releasing options, according to different clinical situations, and the caries susceptibility to manage cavitated carious lesions in permanent adult teeth.

Full textAbstract:
The article presents the results of electron microscopy of 52 teeth with acute and chronic initial caries infiltrated with “Icon” material (DMG, Germany). According to the results of the study, in acute initial dental caries (white spot stage), the infiltrate filled almost the entire volume of the pathological focus (81.8 ± 6.7% of cases). The technique of infiltration by replacing the lost mineral with a low-viscosity light-curing resin creates a barrier inside the carious lesion. Minimally invasive approaches, including the enamel infiltration technique, can be used for caries in the white spot stage for therapeutic-prophylactic purposes. However, in the case of chronic initial caries (pigmented spot stage), the infiltrate does not infiltrate the entire depth of the lesion. In 79.0 ± 9.4% of the teeth of this group, non-infiltrated areas of carious lesions were localized within the surface layers of dentin. Extrapolating the results obtained to the clinic, we can assume that the infiltration of initial caries at the stage of a pigmented spot does not ensure the stabilization of the carious process. Clinical recommendation of the low-viscosity resin infiltration technique requires evidence that requires long-term clinical observations.

Full textAbstract:
Background. When silver diamine fluoride (SDF) is used in conjunction with conservative caries removal in deep carious lesions, the distribution depth of silver is critical for safety and effectiveness. Objective. The purpose of this study is to determine the effect of selected caries removal on silver penetration when 38% SDF is applied to deep carious lesions in permanent teeth. Methods. Extracted permanent teeth with caries extending to the inner third of the dentin were used (N = 18). The periphery of the carious lesion was completely removed to the dentinoenamel junction (DEJ). In group A (n = 9), no further removal of carious tissue was performed, leaving necrotic dentin inner to the DEJ, whereas in group B (n = 9) superficial necrotic dentin was completely removed until leathery, slightly moist, reasonably soft dentin remained. SDF was applied for 3 minutes in both groups. Microcomputer tomography (micro-CT) and field emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (FESEM-EDS) were used to measure mineral density and silver distribution. The silver penetration depth/lesion depth (PD/LD) ratio was calculated for each sample. The Mann–Whitney U test was used to compare differences between the two groups. Results. The micro-CT analysis showed that the PD/LD ratios of group B (1.07–2.29) were marginally greater than those of group A (1.00–1.31). However, a statistically significant difference was not observed ( p value = 0.5078). When stratified by remaining dentin thickness (RDT), the PD/LD ratios of group B were still greater than those of group A only when RDT was >500 µm. The FESEM-EDS analysis indicated that silver particles precipitated throughout the entire thickness of the carious lesions. Conclusion. Applying SDF on a deep carious lesion and leaving the necrotic dentin pulpally did not affect silver penetration. However, the extent to which silver penetrates the remaining dentin beneath the lesions is dependent on the amount and characteristics of that dentin.

The article provides a brief overview of the studies regarding changes in the structure and composition of teeth after eruption. The factors of degenerative changes in tooth structures and their relationship with non-carious lesions have been analyzed. The study makes emphasis on the tooth durability and the factors influencing tissue fatigue, explaining increased tissue wear due to local factors. Understanding mechanisms of metabolism of teeth hard tissues is the key to the stability of restorative treatments and occurrence of non-carious tooth lesions. The evolution of views on this problem is noteworthy. The literature review reveals the initial predominance of mechanical actions, abrasion, and mineralization. It is later complemented by a detailed analysis of the influence of destructive stresses and deformation due to mechanical factors. All the leading works of the 2000s are dedicated to analyzing the ultrastructural features of enamel that affect its mechanical characteristics and can explain both the characteristics of the shape and intensity of mechanical tooth wear during the functioning of the stomatognathic system, as well as the durability of the performed restorations. The literature review covers 74 sources over the past 15 years.

The aim: To study the intensity and depth of carious tooth lesions in rats with experimental juvenile adjuvant-induced arthritis. Materials and methods: An experimental study on a model of juvenile adjuvant arthritis (JAA) in 10 one-month-old rats induced by method of A.M. Bendele was carried out. 10 rats of the same age were intact. Injection of adjutant in rats of experimental group led to the development of acute local reaction and then caused generalized joint reaction of autoimmune origin. The performed basic therapy of JAA promoted transition of acute autoimmune process to chronic. Rats were withdrawn from the experiment in 58 days and the dental-jaw blocks were made, in which the intensity and depth of carious lesions of the masticatory group of teeth were determined. Results: The course of JAA was accompanied by the development of dental caries in 100% of experimental animals. It was found that the intensity of carious teeth lesions in terms of the number of carious teeth and cavities is probably higher than in intact rats (respectively 4.3 ± 0.3 vs. 2.2 ± 0.6 and 4.5 ± 0.3 vs. 2.3 ± 0.7, p <0.001). In rats with JAA, mostly middle and deep carious cavities were revealed, at the same time in intact rats – superficial and middle carious cavities were observed. Conclusions: It has been established that adjuvant arthritis is accompanied by 100% prevalence of dental caries, high intensity of carious process, presence of middle and deep carious cavities, that confirm the negative influence of autoimmune disease on the condition of the hard tooth tissues.

Introduction. Detection of early carious lesion and its remineralization is the most effective way for caries treatment. The aim of this study is to compare effectiveness of remineralization of the early carious lesions with different fluoride varnishes. Method. The research included 30 children, girls and boys, aged 12 and 13, in whom the presence of white lesions on at least two vestibular surfaces was detected on 60 permanent teeth during a clinical examination by visual method. Gingival status was determined based on bleeding or non-bleeding after probing, activity of the white lesion was visually examined and the size of the lesion was measured. After the measurement, the application of varnishes was performed by the procedure that two different dental varnishes were applied to two different teeth with white lesion in the same person: group I - fluoride varnish with 1.5% non-organic ammonium fluoride, group II - fluoride varnish enriched with minerals with 5% sodium fluoride. Activity, lesion dimensions and gingival status were examined after four, eight and twelve weeks when new varnishes were also applied. Results. Inactivation of white lesions was recorded in the eighth week, but statistically significant difference was recorded after twelve weeks with 56.2% inactive lesions in the group I and 57.5% in the group II. There was no recorded difference in the lesion activity of the varnishes. Changes in the gingivo-incisal diameter during the visits amounted to: 3.47 mm/3.59 mm/3.53 mm/3.46 mm for the group I and 3.21 mm/3.19 mm/3.18 mm/3.20 mm for the group II. Changes in mesio-distal diameter amounted to: group I: 2.94 mm/2.81 mm/2.84 mm/2.4 mm; group II: 2.94 mm/2.87 mm/2.89 mm/2.90 mm. Statistically significant difference in both diameters was recorded between the first and second visit in the group I (p = 0.0046). There was no statistically significant difference recorded in the group I during other visits. In the group II statistically significant differences in the changes of lesion dimension were not recorded. Statistically significant differences p< 0.001 were recorded in the presence of gingival bleeding between the examined groups at the first visit, where significantly more lesions with healthy gingiva were observed in group I (84.4%). Conclusion. Dental fluoride varnishes cause remineralization of early carious lesion after twelve weeks without significant difference between classic and enriched varnishes.

Full textAbstract:
Background: the aim of this study was to assess the 2-year pulp survival of deep carious lesions in teeth excavated using a self-limiting protocol in a single-blind randomized controlled clinical trial. Methods: At baseline, 101 teeth with deep carious lesions in 86 patients were excavated randomly using self-limiting or control protocols. Standardized clinical examination and periapical radiographs of teeth were performed after 1- and 2-year follow-ups (REC 14/LO/0880). Results: During the 2-year period of the study, 24 teeth failed (16 and 8 at T12 and T24, respectively). Final analysis shows that 39/63 (61.9%) of teeth were deemed successful (16/33 (48.4%) and 23/30 (76.6%) in the control and experimental groups, respectively with a statistically significant difference (z score = 2.3, p = 0.021). Of teeth with severe and mild symptoms at T0, 42.9% and 36.7% respectively failed at T24 (p > 0.05). Within the self-limiting group, there was a lower success in premolars compared to molars (p < 0.05). Conclusion: after 2 years, there was a statistically significant higher pulp survival rate of teeth with deep carious lesions excavated using self-limiting protocols in patients with reversible pulpitis. Molars showed higher success than premolars in teeth excavated using the self-limiting protocol. There was no statistically significant association between the outcome and the severity of symptoms at T0 (ClinicalTrials.gov NCT03071588).

Objective: To compare the effect of glass ionomer cement (GIC) and fluoride varnish (F-varnish) on artificial proximal caries in situ. Study design: Two 1×3 mm2 enamel slabs, divided into three 1×1 mm2 windows,were prepared from each proximal surface of 18 premolars. Each slab was distributed into a control area,an intact enamel area and a test area. Artificial lesions were created on the control and test areas by immersing in demineralizing solution for 24 hours. The test windows were either applied with GIC or F-varnish and the full slabs inserted into orthodontic brackets as carriers, which were then bonded to the buccal surfaces of the 6 upper posterior teeth of 6 volunteers using non-fluoride dentifrice for 30 days. There was a 1-week washout period in this crossover study. The middle specimens of the three windows were cross-sectioned to analyze the carious lesion area by a polarized light microscope and calculated with Image-Pro plus® software.Results: The average carious lesion area under GIC was significantly less than that under F-varnish(p&lt;0.05). Conclusion: GIC promotes more remineralization of artificial carious lesions on proximal surfaces than F-varnish.

Introduction. The restoration of non-carious cervical lesions is specific, mostly because of the location of their margins, especially the cervical margin, which is determined in cement and/or dentine. This feature makes the cervical margin more susceptible to micro-leak?age, causing marginal discoloration, postoperative sensitivity, development of the secondary caries and loss of the restoration. Material and methods. One of the criteria for inclusion of a patient in this study was the presence of at least two non-carious cervical lesions to be restored with the minimum depth of 1mm, independently of their location in the dental arch. A total of 60 restorations were placed in 30 patients, and every patient received both tested materials (composite resins and compomer) on their non-carious cervical lesions. The clinical evaluation of the therapeutic success was performed six months and then one year after the day of the placement of restorations using the modified-United States Public Health Service criteria. The following was evaluated: retention, marginal integrity, marginal discoloration, wear, postoperative sensitivity and secondary caries. Results. A statistically significant high percent of restorations/teeth with postoperative sensitivity was found in the group of resin composite restorations after six months. At the end of the evaluation period, that is after one year, there were no statistically significant differences between materials for all evaluated criteria. Conclusion. The results of this study show the identical quality of both examined materials one year after the readjustment of non-carious cervical lesions.
