Full textAbstract:
The root canal anatomy of mandibular second molar teeth is known to be highly variable. Whilst the most frequently seen configuration is two mesial canals and one distal canal, other variations such as four canals, two canals, and C-shaped canal system do also exist. This case report describes the diagnosis and management of unusual root canal configuration of a mandibular second molar, with one canal in a single conical root, using the contemporary advancements in endodontics. Following clinical and radiographic examinations of the case, a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis of tooth #47 was established, and root canal treatment followed by composite buildup and crown were planned. Clinicians should be aware of the different anatomic variants each tooth may exhibit. Furthermore, clinicians need to possess the proper knowledge and skills that allow them to utilize the diagnostic and therapeutic tools available at their disposal in order to optimize the quality of care provided to their patients.

SUMMARYAim: To evaluate technical quality of root canal treatments performed in extracted anterior single-rooted teeth in an undergraduate dental clinic, and to record the associated iatrogenic errors.Material and Method: 287 root canal treatments performed by 114 preclinical undergraduate students in extracted anterior teeth at the Department of Endodontology were radiographically evaluated, based on the following parameters: access cavity dimensions and direction, root canal instrumentation, and root canal filling quality.Results: The access cavity was found of adequate dimensions in 28.9% and straight in direction in 71.1% of the material. Erroneous position, overextension of the access cavity and non-straight access were noted in 39.7 %, 21.6% and 28.9% of the cases, respectively. The frequency of ledged root canals was 10.1%, while 84.7% of the teeth had no instrumentation related iatrogenic errors. Regarding root canal filling, incomplete density apically and technical inadequacies in the middle and cervical thirds were observed in 76.3% and 82.3% of the cases. The percentage of flawless endodontic treatments was 3.1%.Conclusions: Most of the endodontic treatments evaluated were classified unacceptable. Inadequate root canal filling density in the middle and cervical third and ledge formation were the most common faults.

Full textAbstract:
The proper knowledge of the root canal system anatomy is crucial to perform successful endodontic treatments. Maxillary lateral incisors usually have a single root. However, aberrant canal configurations of this tooth have been reported in the literature. The clinician should be aware of the difficulties arising from this more complex root canal anatomy and should be able to manage them. A rare case of a maxillary lateral incisor with three root canals is presented in this article; the challenge of diagnosis and treatment in similar situations is also discussed.

Full textAbstract:
The mandibular canine is usually considered a single-rooted tooth with a single root canal. However, two canals and more rarely two roots may also occur. This paper reports the case of a patient with bilateral mandibular canines with two roots and two root canals. The initial periapical radiographs of the mandibular right and left canines for endodontic treatment revealed the presence of two roots in each tooth. After coronal opening, the cervical third was prepared with a SX file of the ProTaper® system and root canal length was confirmed using Root ZX electronic apex locator. Root canal preparation was completed with the series of ProTaper® instruments and the root canal was filled with gutta-percha and an epoxy resin-based endodontic sealer according to Tagger's hybrid technique. The final radiographs showed two well-obturated canals ending at the electronically located apexes. The 6-month posttreatment follow-up showed apparent clinical and radiographic success. Clinicians should always consider the presence of anatomical variations in the teeth during endodontic treatments. Despite the low prevalence, variations may occur in the number of roots and root canals of mandibular canines, as demonstrated in this case report.

Background: The aim of this study was to compare the success rate of root canal treatments undertaken using a calcium silicate root canal sealer in combination with a single cone with non-calcium silicate cement and warm vertical condensation. Methods: 150 necrotic or pulpitic teeth were treated. (REC: 08/H0804/79). Following standardized root canal chemo-debridement. The canals were obturated using warm vertical condensation of gutta-percha and epoxy-based sealer (AH plus) or a calcium silicate sealer (BioRootTM RCS) with a single cone technique. Follow-up assessment was conducted at 12 months using Cone Beam Computed Tomography (CBCT). Results: At 1-year recall, 104 teeth were assessed (51 AH plus, 53 BioRootTM RCS). The success rate using loose criteria for the CBCT images and PA radiographs was respectively 80% and 89% in the AH plus/warm vertical condensation group, 84% and 90% in the BioRootTM RCS/single cone group. There was no statistically significant difference between the two groups (Fisher exact test p value 0.6099 for the CBCT images). Conclusion: Within the limitations of this non-randomized trial, a calcium silicate cement in combination with single cone resulted in a similar proportion of successful cases compared to warm vertical condensation and epoxy-based sealer.

Clinicians need to have intimate knowledge and thorough understanding of both pulp chamber and root canal anatomy. They should be aware of possibility of anatomical variations in the root canal system during endodontic treatment. Maxillary canines usually have single root and root canal but rarely may have single root with two root canals. This case describes a lengthier maxillary canine with two root canals.

Full textAbstract:
This study evaluated the long-term clinical outcomes of single-visit root canal treatments with apical enlargement on patients with necrotic pulp tissue retrospectively. A total of 137 teeth with necrotic pulp tissue which underwent single-visit root canal treatments were included. The root canals were shaped up until the apical constriction, which was determined by an apex locator. The outcomes were evaluated by two independent and calibrated endodontists clinically and radiographically. Teeth were dichotomized into healed ( PAI ≤ 2 , no signs or symptoms) and nonhealed ( PAI > 2 , with/without signs or symptoms) groups. Each patients’ preoperative PAI and lesion size were recorded to evaluate the preoperative periapical status as well as several other prognostic factors. Statistical analyses were performed ( p = 0.05 ) on ninety teeth. The mean observation time was 60 months. Out of ninety teeth, 87 (96.7%) were healed and 3 (3.3%) were nonhealed. No correlations were found between the prognostic factors and the outcomes ( p > 0.05 ). Cohen’s kappa and Gwet’s agreement coefficient scores between the preoperative PAI scores and preoperative lesion sizes showed good agreements, with values of 0.834 and 0.898, respectively. Apical enlargement is a viable treatment option for single-visit root canal treatments.

Resultados: Se encontró un elevado puntaje de confianza (8.51) en los estudiantes al realizar una endodoncia uniradicular y los puntajes más bajos fueron al determinar la longitud de trabajo y la obturación de los conductos con un promedio de 8.19 y 8.01. Asimismo, existen diferencias estadísticamente significativas entre la experiencia previa (p=0.007), percibir complicado el tratamiento (p=0.009) y haber tenido una complicación (p=0.004) con la variable confianza; y una correlación positiva estadísticamente significativa entre las dimensiones de la variable percepción de la enseñanza en endodoncia (p=0.003) (p=0.000) (p=0.000) y la variable confianza.
Conclusiones: Existe una elevada confianza al realizar tratamientos de conductos uniradiculares en los estudiantes de 4to y 5to año de la carrera de Odontología.Objective: To determine the confidence when performing single root canal treatments of the 4th and 5th year students of the Dentistry career at a Private University of Lima. Materials and Methods: Eighty-one dental students from a private university in Lima were evaluated through a survey of the article prepared by Davey to measure their confidence when performing single root canal treatment. Internal validity was verified through questionnaire translation processes, expert judgment and a pilot test. Adequate coefficient of Aiken’s V (0.91), Cronbach’s Alpha (0.89), and Spearman’s correlation (0.61) were obtained. Descriptive statistical measures were obtained (Mean, S.D, Median, and IQR) and for the bivariate analysis, U Mann Whitney's, Kruskal Wallis, Dunn Test and Spearman's Correlation tests were used. Results: Students had a high confidence score (8.51) when performing a single root canal treatment and the lowest scores were when determining the length of work and the obturation of the canals with an average of 8.19 and 8.01 respectively. Likewise, there was statistically significant differences between previous experience (p=0.007), perceiving the treatment as complicated (p=0.009) and having had a complication (p=0.004), with the confidence variable; and a positive correlation statistically significant between the dimensions of the variable perception of teaching in endodontics (p=0.003) (p=0.000) (p=0.000) and the confidence variable. Conclusions: There is high confidence when performing single root canal treatment by the students of 4th and 5th year of the Dentistry career.

Full textAbstract:
The goal of the root canal filling procedure is the total 3-dimensional filling of root canals and accessory canals. With the development of innovative sealers and gutta percha in matching taper and diameter as rotary instruments, the single cone technique is gaining popularity. Objective: To compare the percentage of voids and gaps in the coronal, middle and apical third of mandibular molar root canals obturated with different sealers and techniques using micro-computed tomography. Hypothesis: No differences in the percentage of voids and gaps are found between: 1) the obturation groups; 2) the mesial or distal canals of the mandibular molars; and 3) the root canal thirds. Methods: Thirty extracted two-rooted human mandibular molars were divided into three experimental groups: 1) single cone technique using ThermaSeal Plus sealer; 2) warm vertical technique using ThermaSeal Plus sealer; and 3) single cone technique using BC sealer. All canals were instrumented with Vortex Blue 0.04 files to an apical size of #35 (mesial) and #40 (distal). The teeth were mounted on a custom attachment for post-instrumentation and post-obturation micro-CT scan. The scans were examined for the relative proportions of voids and gaps in the coronal, middle and apical third of mandibular molar root canals. Data were analyzed with mixed effects models and Wald chi-square test. Results: A statistically higher percentage of gaps was found in the apical third compared to the coronal third and the middle third of the canal (p <0.05). No significant differences in voids were found in the root canal thirds. No significant differences in voids and gaps were found between the three obturation groups or between the mesial and distal canals (p > 0.05). None of the methods were able to produce a void-free root filling and voids occurred in both mesial and distal canals with no predilection for any part of the canals. Conclusion: Within the limitations of this study, it appears that the single cone technique utilizing gutta percha in matching taper and size as rotary instruments is a suitable alternative for obturation of mandibular molars as compared to the warm vertical technique.Dentistry, Faculty of

O objetivo deste estudo ex vivo foi avaliar o selamento apical e a resistência de união à dentina radicular da obturação de canais radiculares usando a técnica do cone único dos sistemas WaveOne e Reciproc com diferentes cimentos, em comparação à técnica da condensação lateral. Foram selecionados caninos superiores humanos cujas coroas foram removidas permanecendo as raízes com 15 mm. A amostra foi distribuída aleatoriamente de acordo com o sistema de instrumentação/ técnica de obturação: Reciproc R40/Cone único R40; WaveOne Large/Cone único Large e ProTaper Universal (até instrumento F4)/Condensação lateral. Posteriormente, 9 subgrupos (n=20) foram estruturados conforme o cimento endodôntico: AH Plus, Epiphany SE e MTA Fillapex. Após preparo biomecânico e obturação dos canais radiculares, os espécimes foram armazenados a 37°C e 100% de umidade por período correspondente a três vezes o tempo de endurecimento dos cimentos. O método de filtração de fluidos foi utilizado para verificação do selamento apical em 10 espécimes de cada subgrupo. Espécimes apenas com cone de guta-percha e sem cimento (n=6) e outros completamente impermeabilizados (n=2) foram os controles positivos e negativos, respectivamente. Dos 10 espécimes remanescentes de cada subgrupo foram obtidas fatias de dentina com 1 mm de espessura (3 por terço radicular: cervical, médio e apical), sendo 6 (2 fatias por terço) utilizadas para o teste de push-out. O tipo de falhas ocorridas após a desunião foi avaliado em microscópio óptico (25X de aumento). Dentre as outras fatias, foram selecionadas 5 de cada terço, em cada subgrupo, para análise por microscopia eletrônica de varredura (MEV) (1000X de aumento). Foram mensurados doze pontos na interface material obturador/dentina e os seguintes escores foram atribuídos para a adaptação da obturação: 0 (seções sem lacunas); 1 (seções com pequenas falhas, <1 μm); 2 (seções com muitas lacunas, entre 1 μm e 10 μm) e 3 (sem adaptação, lacunas >10 μm). Os dados de infiltração apical e resistência de união (RU) foram analisados pelo teste ANOVA duas vias e teste de Tukey (p<0,05). Os testes de Kruskal-Wallis e Student-Newman-Keuls (p<0,05) foram utilizados para análise dos dados referentes à adaptação da obturação. Em relação ao selamento apical, as três técnicas apresentaram diferenças entre si, com melhores resultados para a condensação lateral (p<0,05). A técnica WaveOne propiciou menor índice de filtração de fluido que a Reciproc, sem diferença estatisticamente significante entre os cimentos (p>0,05). As técnicas de cone único apresentaram menores valores de RU que a condensação lateral (p<0,05), enquanto nesta última técnica o cimento AH Plus apresentou os maiores valores de RU, sendo estatisticamente superior ao MTA Fillapex e Epiphany SE (p<0,05). Houve predominância de falhas adesivas à dentina no terço apical e mistas nos terços médio e cervical. A análise por MEV mostrou melhor adaptação na interface dentina/material obturador para o cimento AH Plus que para os cimentos MTA Fillapex e Epiphany SE (p<0,05). Concluiu-se que as técnicas de cone único apresentaram maior infiltração apical e menor resistência de união que a condensação lateral. Melhor adaptação marginal foi obtida com o cimento AH Plus, independentemente da técnica de obturação utilizada.The aim of this ex vivo study was to evaluate the apical sealing and bond strength (BS) of root canal filling using single-cone from WaveOne and Reciproc systems associated to different sealers compared with the lateral condensation technique. The crowns of maxillary human canines were sectioned in order to standardize the root length to 15 mm. The sample was randomly allocated according to instrumentation system /obturation technique: R40 Reciproc file/ R40 single cone; WaveOne Large/Large single cone; ProTaper Universal (up to F4 file)/ Lateral condensation. Subsequently, 9 subgroups (n=20) were defined according to root canal sealer: AH Plus, Epiphany SE and MTA Fillapex. After the preparation and filling procedures, the specimens were stored at 37°C and 100% humidity for a period three times longer than the setting time of the sealers. The fluid filtration method was used to investigate the apical sealing in 10 specimens of each subgroup. Specimens with only cone and without sealer (n=6) and others completely sealed (n=2) were used as positive and negative controls, respectively. Slices with 1 mm thickness (3 per root third: cervical, middle and apical) were obtained from the remaining specimens of each subgroup, while 6 slices (2 per third) were submitted to push-out test. Failures modes were evaluated in optical microscope (magnification 25X). Among the other slices for each experimental condition, five were selected from each third for analysis by scanning electron microscopy (SEM) (magnification 1000X). Twelve points were measured in filling material/dentin interface, and the following scores were used in order to evaluate the root filling adaptation: 0 (sections without gaps); 1 (sections with small gaps, <1μm); 2 (sections with many gaps, between 1 μm and 10 μm) and 3 (without adaptation, gaps>10 μm). The data on apical infiltration and BS were analyzed by two way ANOVA test and Tukey′s test (p<0.05). The Kruskal-Wallis test followed by Student-Newman-Keuls test (p<0.05) were used for data analysis concerning the adaptation of the root filling. Regarding the apical sealing, there was statistical difference between the obturation techniques, whereas the lateral condensation showed the best results (p<0.05). The WaveOne technique provided lower rate of fluid filtration than Reciproc, and no statistically significant differences were observed between the sealers (p>0.05). The single-cone techniques showed lower values of BS than lateral condensation, in which AH Plus showed the highest BS values, with statistical difference from MTA Fillapex and Epiphany SE (p<0.05). There was predominance of adhesive failures in the apical third and mixed failures in the middle and cervical thirds. The SEM analysis revealed better adaptation in the filling material/dentin interface for AH Plus than MTA Fillapex and Epiphany SE. It was concluded that the single-cone techniques resulted in highest apical infiltration and lowest BS than lateral condensation one. Better marginal adaptation was obtained with AH Plus, regardless of obturation technique used.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorO objetivo deste estudo foi avaliar a espessura mínima radicular remanescente e o desgaste porcentual do terço cervical em raízes mesiais de molares inferiores, após a instrumentação com as técnicas ProTaper Universal e Lima única F2. Foram obtidos 100 primeiros molares inferiores com raízes completamente separadas. Desse total, foram selecionados e incluídos no estudo somente 22 que possuíam dois canais distintos na raiz mesial, comprimento entre 20 e 22 mm e grau de curvatura da raiz mesial com angulação variando entre 10 e 20. Destes, 8 foram eliminados por possuírem uma anatomia muito discrepante, o que limitava o processamento e análise digital das imagens (PADI). Os dentes foram acessados e a patência apical foi realizada em todos os canais determinando o comprimento de trabalho. Em cada dente, cada canal mesial foi instrumentado por uma técnica diferente. As amostras foram posicionadas em um dispositivo de montagem e digitalizadas através de microtomografia computadorizada antes e depois de serem completamente instrumentadas. O volume de interesse, correspondente à região de zona de risco, com uma grande margem de tolerância, tanto em direção apical quanto em direção cervical, foi determinado por 234 fatias, totalizando um comprimento vertical de 3,5 mm, para avaliação quantitativa comparativa. Através de PADI mediu-se, de forma automática, a espessura mínima radicular nos dois canais mesiais, antes e após a instrumentação, para todas as fatias de todos os dentes. A partir destes dados foi calculado o desgaste porcentual. Após o tratamento estatístico das mais de 6500 medidas obtidas, pôde-se concluir que não existiu diferença no desgaste da zona de risco produzido pelas duas técnicas de instrumentação testadas. Em todos os casos a espessura radicular remanescente permaneceu dentro de uma margem de segurança, não havendo, portanto, nenhum caso de rasgo ou perfuração. Dessa forma, ambas as técnicas estudadas foram consideradas seguras quanto ao desgaste da zona de risco da raiz mesial dos molares inferiores.
The aim of the present study was to evaluate the minimal remaining root canal thickness and percentage of dentin removed of the cervical third of the mesial roots mandibular molars after instrumentation with the ProTaper Universal and Single File F2 Techniques. From a total of 100 teeth, only 22 were selected and included in the study by having two distinct canals in the mesial root with length between 20 and 22 mm and degree of curvature presenting angle between 10 and 20. Eight specimens were eliminated because they have a very disparate anatomy that limited the digital processing and analysis of the images (PADI). The teeth were accessed and patency was performed in all canals determining the working length. In each tooth, each mesial canal was instrumented by a different technique. The samples were placed in a mounting device and scanned by microcomputed tomography before and after instrumentation. The corresponding volume of interest to the region of the risk zone was determined by 234 slices, with a total vertical length of 3.5 mm, for quantitative comparative evaluation with a high degree of tolerance. The PADI performed the measures automatically of the minimal thickness of root in both mesial canals, before and after instrumentation for all slices of each tooth. From these data, the percentage of dentin removed was calculated. After statistical analysis of more than 6500 measurements, it was concluded that there was no difference in the wear of the risk zone produced by the two instrumentation techniques tested. In all instrumented specimens, the root thickness remained within a security margin, thus, no case of strip perforation was observed. Therefore, both techniques were considered safe to be used in mesial root of mandibular molars.

Full textAbstract:
Single-visit root canal treatment was first documented in 1887. The controversy and debate within the dental community has been ongoing for over a century without resolution. The concept of evidence-based health practice has provided a structure on which the clinically-relevant questions in this debate can be dealt with systematically. When clinicians are faced with choices of which treatment regimen should be offered to patients, the central issues that should be considered are effectiveness, complications, patient/operator preference/satisfaction, and cost. Systematic review and meta-analysis techniques were used to reach definitive conclusions where high quality primary studies are available. The issue of satisfaction was studied using a quality of life concept, while the issue of cost was addressed by an economic evaluation (cost-minimization analysis). Treatment effectiveness and complications of single- and multiple-visit approach were similar. Patients overwhelmingly preferred single- over multiple-visit treatment with high satisfaction scores for both regimens. Australian endodontists were reluctant to embrace single-visit root canal treatment. Single-visit root canal treatment costs society less than multiple-visit treatment. On balance single-visit treatment offers substantial advantages with no identified adverse effects.

Background and Objectives: Root canal treatments (RCTs) aim to prevent chronic apical periodontitis and save the infected teeth by eliminating microorganisms from the root canal system. The possible consequences pertaining to systemic diseases with pulpal diseases or inadequate quality of RCT remain controversial. The aim of the present study was to investigate whether rubber dam usage or unfinished RCT could affect the tooth retention rate of RCT teeth and the risks of systemic diseases (cardiovascular disease and pneumonia) using a nationwide population-based database. Methods: Five retrospective cohort studies were conducted by using the records of the Longitudinal Health Insurance Database 2005 from Taiwan National Health Insurance Research Database. Rubber dam usage was identified by a specific treatment code (90012C) during each endodontic session, and an unfinished RCT was defined as a tooth on which an endodontic treatment course was started but with no completion code. Cox proportional hazards models were used to estimate the effects of rubber dam usage or unfinished RCTs on the risk of tooth extraction after RCT and the risk of cardiovascular disease and pneumonia hospitalizations. Results: The tooth extraction hazard ratio for the RCT with rubber dams was significantly lower than that observed for RCT without rubber dams (hazard ratio = 0.81; 95% confidence interval, 0.79–0.84). The tooth extraction hazard ratio for the unfinished RCT was significantly higher than that observed for completed RCT (hazard ratio = 3.24; 95% confidence interval, 3.15–3.33). Compared to the participants without unfinished RCTs, the adjusted cardiovascular diseases and pneumonia hospitalization hazard ratio for the participants with unfinished RCTs was 1.22–3.61 and 1.24−1.59, respectively. Discussion: The start and end of each endodontic therapy session, and rubber dam usage require supporting evidence such as periapical radiographic films for claims, so the codes were reliable for further analyses. Although tooth extraction does not perfectly represent endodontic failures, the present study showed that the use of rubber dams improves the outcome of endodontic treatment. The possible pathological mechanism between unfinished RCT and systemic diseases includes: (i) the symptomatic teeth infected with gram-negative anaerobic bacteria, which can indirectly elevate inflammatory mediator levels and cytokine concentrations; (ii) unfinished root canal treatments might lead subsequent apical periodontitis which can elevate systemic vascular function markers; (iii) unfinished root canal treatments indicated poor oral health which has been proven as a risk factor for CVD and pneumonia. Conclusions: The use of a rubber dam during RCT could provide a significantly higher tooth retention rate after initial RCT. This result indirectly supports that rubber dam usage improves the outcomes of endodontic treatments. On the other hand, RCT left unfinished can lead to tooth extraction, and participants with unfinished RCTs were associated with a higher risk of cardiovascular diseases and pneumonia hospitalization. Dentists are thus advised to complete endodontic treatments once started.

The root canal systems of anterior teeth in Asian population are quite different from Caucasian population. Clinically, when nonsurgical root canal treatment fails, surgical endodontic treatment is highly indicated. In the consequence of micro-computed tomography producing undistorted three-dimensional images without destroying the analyzing object, it would be helpful to understand the root canal morphology in clinical nonsurgical and surgical root canal treatment. The purpose of this study was to investigate the root canal morphology of extracted single-rooted anterior teeth using micro-computed tomography in a Taiwanese population. Ninety-nine extracted single-rooted human anterior teeth were collected. All of the teeth were scanned by micro-computed tomography. The anatomy of each tooth, including length of the root, type of root canal system, number and location of canals, number and location of lateral canals, consistency and distance between apical center and apical foramen of main canal, diameter of apical foramen of main canal, diameter of apical foramen of lateral canal, and presence of apical delta were evaluated. The apical center deviated from apical foramen of main canal frequently. The average deviation distance in upper anterior teeth was 0.8 mm. In lower anterior teeth, the mean distance was 0.6mm between apical center and apical foramen of main canal. Of the fifty upper anterior teeth studied, 56% teeth demonstrated lateral canals. Among the forty-nine lower anterior teeth, 28.6% teeth revealed lateral canals. Most of lateral canals were located frequently within the 3 mm region from the apical center. For upper anterior teeth, there were 79.17% of lateral canals situated within the 3 mm from the apical center. Moreover, 94.44% of lateral canals within the 2 mm from the apical center were found in lower anterior teeth. The deviation distance between apical center and the apical foramen of main canal would be a great clinical reference for estimating working length during non-surgical root canal treatment. In surgical endodontics, the location of lateral canals could help endodontists to decide the length for root-end resection. For maxillary anterior teeth, the lateral canals were situated in a wide range between apical center and the bifurcated origin. While performing microscopic periapical surgery in maxillary anterior teeth, the length of apical root resection should be determined case by case. However, in those lower anterior teeth with short root length, resecting 2 mm of apical root would be able to remove 94.44% of lateral canals.

Full textAbstract:
Indiana University-Purdue University Indianapolis (IUPUI)The purpose of this study was to evaluate the fracture resistance of three post and core systems in endodontically treated teeth by loading to failure, and to measure marginal gaps before and after cyclic loading. Sixty extracted canines were assigned to three groups. The groups tested were: 1) Single cast post and core (Group CP). 2) Prefabricated metal post and composite resin core (Group MR). 3) Glass fiber post and composite resin core (Group FR). All teeth were obturated and prepared to receive a post and core with a coping. Thirty teeth (10 from each group) were loaded to failure, and the other 30 teeth were fatigue-loaded. The marginal gaps on the facial and lingual surface of the fatigue-loaded group were measured before and after cyclic loading. There were two hypotheses for this study. The first was that the FR group would have less marginal gap opening on the lingual surface than the other groups. The second was that the CP group would have a higher load at failure than the other groups. Group CP was found to have a significantly smaller pre-loading marginal gap than group FR (p = 0.0265) and group MR (p = 0.0273), while groups FR and MR did not have a significantly different pre-loading marginal gaps (p = 0.86). Group FR had significantly less change in marginal gap than group MR (p = 0.0013). Groups CP and MR did not have significantly different changes in marginal gap (p = 0.09). Groups CP and FR did not have significantly different changes in marginal gap (p = 0.11). The three post types did not have significantly different maximum loads to failure (p= 0.49), moments of inertia at cervical area (p = 0.75), or moments of inertia at fracture site (p=0.12). There was no significant difference between groups CP, FR, and MR in the load-to-failure test. Group CP demonstrated the highest load-to-failure values; however, the highest load-to-failure mean was for group MR. All fractures observed in this study were catastrophic. Group FR demonstrated better stress distribution and caused no early fractures in the fatigue-loading group. All groups demonstrated significant marginal gap changes on the lingual surface after fatigue loading; however, group FR demonstrated <45 μm marginal gap opening. In group FR, the reduced marginal gap opening was attributed to the use of Panavia 21 with the proper surface treatments to bond to the tooth structure, the resin composite, and the metal coping.

Dentistry involves the study, diagnosis, prevention, and/or treatment of diseases, disorders, and conditions of the oral cavity, including the teeth, gums, and tissues. Dentistry is thought to be one of the first areas of specialization to emerge from medicine, with evidence of drilled teeth dating back 9,000 years. The most common conditions treated within dentistry involve tooth decay (dental caries) and gum disease (periodontal disease), with common dental procedures including x-rays, restorative treatments (such as fillings, crowns, and bridges), prosthetics (dentures), orthodontics (such as teeth braces), tooth extraction and endodontic (root canal) therapy. Dentistry also involves public health work such as the encouragement of oral disease prevention through dental hygiene and check-ups....

This chapter examines Hoodoo as health care and the role of the African American midwife in the old tradition black belt Hoodoo complex. Scholarship has totally overlooked a discussion of traditional Hoodoo healers: treaters, midwives, and root doctors. Even African Americans who know anything of contemporary Hoodoo will usually not immediately associate it with medicinal herbalism. Hoodoo marketeers were neither interested in nor had access to this aspect of Hoodoo. This chapter considers how Hoodoo midwives, treaters, and root doctors mastered treatments and developed their regional pharmacopoeia. It discusses one technique used by all three types of Hoodoo health care providers: the method of using string to tie sacred healing knots. It also describes nine types of healing amulets used in Hoodoo: single-knot string amulet; multiknot amulet; root necklace; prayer bead necklace; prayer cloth; biblical scroll; walking cane; religious lithography; and silver coin.

Full textAbstract:
Esophagitis is a debilitating disease often leading to more serious conditions. It is aggravated by refluxed stomach acids for which the usual treatment is PPI drugs that at best treat the symptoms, not the underlying cause of reflux. Surgical interventions address the root - Hiatal muscular incompetence - but are invasive and expensive. Both treatments have proven unwanted side-effects. Neuromuscular treatment is a new and innovative alternative that addresses the root cause of reflux. The science and evidence behind this treatment is presented here. Reflux cannot happen when the diaphragm functions properly and maintains adequate pressure in the Hiatal canal, otherwise the neck of the stomach can intrude through the diaphragm into the chest cavity allowing reflux and conditions such as GERD, LPR, silent reflux, dyspepsia and more. This is especially common at night, when in bed. Training with a simple and inexpensive neuromuscular medical device takes 90 seconds per day, self-administered by the patient without medication or surgical intervention. No negative side effects are recorded for this treatment. Currently, 40 000 individuals have treated with the device. It is deployed in healthcare institutions in several countries and is recognised in the UK by NICE in a briefing to the NHS as a treatment for Hiatal hernia.

Full textAbstract:
A pain-free, functioning, and good-looking dentition for a lifetime seems a reasonable goal! Is this what dentists do? An advertisement for a North American dental practice recently suggested that dentists practising general dentistry provide amalgam and composite fillings, sealants, cosmetic dentistry, pulp and root canal treatment, crown and bridges, dentures, and dental implants. Moreover, they do minor oral surgery, gum disease treatment, and occasionally temporomandibular joint (TMJ) therapy, tobacco cessation, and nutrition counselling. The topics listed in the first sentence comprise the daily work in general dentistry, but do you realize that 85% of these are a direct consequence of dental caries? Yet dental caries is not mentioned as the main reason for most dental treatments. Restorative treatment is the focus of dentistry. The disease dental caries is the only disease which has been combatted with metals and composites for more than a century. Some 50 years ago the concept of prevention became fashionable. Now restorative treatment was described as ‘secondary prophylaxis’ because it was considered that once the inevitable dental caries had occurred, it had to be treated (i.e. restored) to prevent further break down of the teeth and the dentition. Therefore, it is not surprising that the most time in the dental curriculum is devoted to the many skilled restorative procedures. These have to be conducted in a moist, slippery, small, and moving oral cavity attached to a person who may find the procedure unpleasant! No wonder it is difficult to perform intra-oral restorative work of high quality as part of oral rehabilitation, and no wonder so much time in the curriculum is devoted to these aspects. However, supposing it was possible to prevent or control the disease so that restorations are reduced to a minimum? This control of caries is what this book is about! Seven chapters present the essentials of what is known about dental caries. The observations will be based on current scientific evidence. This is a hands-on book, which means that what is suggested and observed should have immediate implications for how patients may be treated.

Full textAbstract:
Lasers have been used in dentistry for removing hard tooth tissue for more than twenty years. Erbium, chromium: yttrium, scandium, gallium, garnet (Er, Cr: YSGG) lasers are currently being investigated for disinfecting the root canal system, since bacteria can spread from the root canal surface to the deep dentin via the dentin tubules [1]. It is expected that temperature elevation in the deep dentin is sufficient to eradicate bacteria there. Prior to using laser therapy, it is important to understand the temperature distribution and to assess thermal damage to the surrounding tissue. In this study, we develop a heat transfer model to estimate the temperature elevations in both the tooth root and surrounding tissue during Er,Cr:YSGG laser disinfection of the root canal surface. The laser power level, pulse setting, as well as laser duration are incorporated into the Pennes bioheat equation for the theoretical study. We propose a treatment protocol that achieves better heat penetration with shorter treatment time than the existing protocols used in dentistry [2].

Full textAbstract:
[This Proceedings paper was revised and published in the 2019 issue of the journal Issues in Informing Science and Information Technology, Volume 16] Aim/Purpose: The aim of this study was to develop a prototype of an information-generating computer tool designed to automatically map the dental restorations in a panoramic radiograph. Background: A panoramic radiograph is an external dental radiograph of the oro-maxillofacial region, obtained with minimal discomfort and significantly lower radiation dose compared to full mouth intra-oral radiographs or cone-beam computed tomography (CBCT) imaging. Currently, however, a radiologic informative report is not regularly designed for a panoramic radiograph, and the referring doctor needs to interpret the panoramic radiograph manually, according to his own judgment. Methodology: An algorithm, based on techniques of computer vision and machine learning, was developed to automatically detect and classify dental restorations in a panoramic radiograph, such as fillings, crowns, root canal treatments and implants. An experienced dentist evaluated 63 panoramic anonymized images and marked on them, manually, 316 various restorations. The images were automatically cropped to obtain a region of interest (ROI) containing only the upper and lower alveolar ridges. The algorithm automatically segmented the restorations using a local adaptive threshold. In order to improve detection of the dental restorations, morphological operations such as opening, closing and hole-filling were employed. Since each restoration is characterized by a unique shape and unique gray level distribution, 20 numerical features describing the contour and the texture were extracted in order to classify the restorations. Twenty-two different machine learning models were evaluated, using a cross-validation approach, to automatically classify the dental restorations into 9 categories. Contribution: The computer tool will provide automatic detection and classification of dental restorations, as an initial step toward automatic detection of oral pathologies in a panoramic radiograph. The use of this algorithm will aid in generating a radiologic report which includes all the information required to improve patient management and treatment outcome. Findings: The automatic cropping of the ROI in the panoramic radiographs, in order to include only the alveolar ridges, was successful in 97% of the cases. The developed algorithm for detection and classification of the dental restorations correctly detected 95% of the restorations. ‘Weighted k-NN’ was the machine-learning model that yielded the best classification rate of the dental restorations - 92%. Impact on Society: Information that will be extracted automatically from the panoramic image will provide a reliable, reproducible radiographic report, currently unavailable, which will assist the clinician as well as improve patients’ reliance on the diagnosis. Future Research: The algorithm for automatic detection and classification of dental restorations in panoramic imaging must be trained on a larger dataset to improve the results. This algorithm will then be used as a preliminary stage for automatically detecting incidental oral pathologies exhibited in the panoramic images.

In ASME 2010 Summer Bioengineering Conference. American Society of Mechanical Engineers, 2010. http://dx.doi.org/10.1115/sbc2010-19125.
Full textAbstract:
Total bacterial disinfection and elimination from the human root canal system are crucial in clinical endodontic procedures [Card et al., 2002; Kakoli et al., 2009]. The current approaches relying on mechanical instrumentation and root canal irrigation and medicaments have demonstrated that eradication of bacteria occurs when the bacteria are in direct contact with the medicaments. However, persistent infection following routine treatments has suggested that bacteria may harbor in the root canal anatomical irregularities and/or deep dentinal tubules, therefore, surface irrigation of medicaments may not be able to reach those regions. Heat treatment has been used for obturation of the root canal in endodontic practice. In this study we hypothesize that as an alternative, surface heating using a System B heating catheter through the root canal surface would be effective for bacterial elimination in the deep dentin. The heat-induced cytotoxic response kills bacteria in the root dentin via heat conduction from the thermal energy incident on the root canal wall. In principle, a high power setting and/or a long heating duration can always achieve sufficient temperature elevations in deep dentin. Yet, the detailed temperature distribution inside the dentin and possible thermal damage to the supporting periodontium are unknown. Therefore, it is of clinical importance to perform and investigate temperature elevations in dentin to provide clinicians with an optimized and effective treatment protocol to minimize unnecessary thermal damage to the surrounding structure.
