Academic literature on the topic 'Dental caries – examinations, questions, etc'

Early childhood caries (ECC) is an aggressive form of dental caries occurring in the first five years of life. Despite its prevalence and consequences, little progress has been made in its prevention and even less is known about individuals’ susceptibility or genomic risk factors. The genome-wide association study (GWAS) of ECC (“ZOE 2.0”) is a community-based, multi-ethnic, cross-sectional, genetic epidemiologic study seeking to address this knowledge gap. This paper describes the study’s design, the cohort’s demographic profile, data domains, and key oral health outcomes. Between 2016 and 2019, the study enrolled 8059 3–5-year-old children attending public preschools in North Carolina, United States. Participants resided in 86 of the state’s 100 counties and racial/ethnic minorities predominated—for example, 48% (n = 3872) were African American, 22% white, and 20% (n = 1611) were Hispanic/Latino. Seventy-nine percent (n = 6404) of participants underwent clinical dental examinations yielding ECC outcome measures—ECC (defined at the established caries lesion threshold) prevalence was 54% and the mean number of decayed, missing, filled surfaces due to caries was eight. Nearly all (98%) examined children provided sufficient DNA from saliva for genotyping. The cohort’s community-based nature and rich data offer excellent opportunities for addressing important clinical, epidemiologic, and biological questions in early childhood.

Relevance. Orthodontic pathology contributes to the deterioration of the hygienic condition of the oral cavity in children and increases the risk of developing dental caries and inflammatory periodontal diseases. In this regard, rational and effective oral hygiene becomes especially relevant. Aim of this study is to analyze the results of a questionnaire of children with orthodontic pathology regarding the skills of individual oral hygiene and oral hygiene products they use. Materials and methods. A dental examination of 138 children aged from 14 to 17 years with orthodontic pathology was carried out. Before starting the treatment, the children filled out a specially developed questionnaire that contained 20 questions with suggested answer options. The children were surveyed in the presence of parents; the children answered the questions independently by filling out a Google form, parents were not allowed to intrude into the survey. Results. 73 children (52.9%) followed the recommendations to brush their teeth twice a day in the morning and in the evening. 47 (34.1%) children reported about brushing their teeth in the morning only and 6 (4,3%) children brushed their teeth in the evening. 35 (25.4%) children admitted that they did not brush their teeth every day. 76 children (55.1%), i.e. more than half, were fount to spend no more than 1 minute for toothbrushing, another 35 surveyed children (25.4%) indicated that their brushing time, as a rule, did not exceed 2 minutes, and only 25 children (18.1%) followed the recommended time of 3-5 minutes. Among all the participants, 53 children (38.4%) regularly brushed their teeth after meals, 28 (20.3%) – before meals. 57 children (41.3%) reported no established order between meals and oral routine in the morning, some of them said that oral hygiene might depend on food, others paid no attention to the sequence between meal and oral hygiene. 66 (47.8%) children are not interested in the immediate result of the performed cleaning, 42 children (30.4%) received some information about the quality of oral cavity care only at a dentist’s appointment, 30 children (21.7%) monitored the state of oral hygiene by using mirror without the additional dye indicators. The vast majority of children, 57.2%, used a manual toothbrush for oral hygiene, 31 children (22.5%) reported about regular use of an electric toothbrush, and 28 children (20.3%) indicated for periodic alternation regarding the use of toothbrushes of one or another type of teeth. 58 children (42.0%) indicated that the main motivational incentives for choosing brushes were their design and colour, while 33 (23.9%) and 24 (17,4%) children chose brushes based on the advice of their dentists or parents, respectively. 15 children (10.9%) chose toothbrushes without attaching any importance to this. Every 2-3 months, 67 children (48.6%) replaced a worn-out toothbrush with a new one, every 4-6 months – 27 children (19.6%), 40 children (29.0%) were not interested in the replacement period. All the participants used toothpaste, but half of them, namely, 70 children (50.7%), were guided by its organoleptic properties, colour, package design, etc. when choosing paste; 49 children (35.5%) followed the recommendations of dentists, while 11 children (8.0%) did not think about what toothpaste to choose. Toothpastes with complex action or anti-caries activity were used by 44 (31.9%) and 40 (29.0%) children, respectively, but 22 children (15.9%) did not pay any attention to toothpaste composition, indications and contraindication. Some children are informed about interdental hygiene products. Thus, 21 children (15.2%) reported about regular use of dental floss for interdental cleaning, 12 children (8.7%) also used it, but only occasionally, 26 children (18.8%) indicated that they used an irrigator, but at the same time 105 children (76.1%) never used dental floss, and 112 (81.2%) used an irrigator. Conclusion. According to the results of the questionnaire, the level of awareness of children with orthodontic pathology about rational and effective individual oral hygiene routine and products is far from being completely satisfactory. The development of additional oral hygiene recommendations for children with such problems seems appropriate and necessary.

The study aims to examine correlations between nutrition status with different factors and dental caries of preschool children in rural areas of Vietnam. A big data based on a total of 690 children (356 boys and 334 girls), aged 2–5 years, living in Van Xuan commune, were thoroughly analyzed. Oral examinations were performed by dentists with the assistance of nursery teachers and the research team. Caries was diagnosed using criteria established by the International Caries Detection and Assessment System (ICDAS). The examined children and their parents responded to questions pertaining to dental hygiene practices. The nutrition status of preschool children was determined by the World Health Organization (WHO) standards in 2006. There are factors which have effects on the malnutrition status of children in the research. The prevalence of dental caries also contributed importantly to assess children’s development. In this study, the stunting groups have a higher ratio of caries compared to the others. Children’s morphology and nutritional status are associated with dental caries among the preschool children in Van Xuan commune, Vinh Tuong district, Vinh Phuc province.

Background: Early childhood caries (ECC) is major oral health problem of young children. Risk factors for ECC are poor oral hygiene and feeding practices. Prevalence and severity of ECC is increasing with change in lifestyle and diet pattern in developing countries. Objectives: To assess the association between feeding practices and severity of early childhood caries in preschool children. Methods: An analytical cross-sectional study was conducted with convenient sample of 96 children up to six years age in Peoples Dental College from July to December 2020. Clinical examination included the recording of dental caries (dmft) using WHO criteria. The self-validated questionnaire consisting seven questions about feeding practices was asked to mothers. The Chi-square test was performed to determine association between severity of ECC and feeding pattern. Results: Mean dmft was 6.77 ± 5.91. Prevalence of severe-ECC (S-ECC) was highest in youngest age group. Caries experience was similar in breast fed, bottle fed, and mixed. There was no significant difference in non-severe ECC and ECC in relation to duration of breast or bottle feeding but frequency of night feeding was associated with S-ECC. Children given ready-made infant formula solid food had more S-ECC (13, 92%) compared to non-severe ECC (1, 7.1%) which was statistically significant. Children given homemade gram flour food were noted to have less of S-ECC (5, 27.5%) than nonsevere ECC (13, 72.5%) which was statistically significant. Conclusion: Present study revealed that multiple night feeding and weaning with readymade food are significant factors for S-ECC.

<br/><b>Purpose</b> - The aim of this study was to use probabilistic graphical models to determine dental caries risk factors in three-year-old children. The analysis was conducted on the basis of the questionnaire data and resulted in building probabilistic graphical models to investigate dependencies among the features gathered in the surveys on dental caries. <br/><b>Materials and Methods</b> - The data available in this analysis came from dental examinations conducted in children and from a questionnaire survey of their parents or guardians. The data represented 255 children aged between 36 and 48 months. Self-administered questionnaires contained 34 questions of socioeconomic and medical nature such as nutritional habits, wealth, or the level of education. The data included also the results of oral examination by a dentist. We applied the Bayesian network modeling to construct a model by learning it from the collected data. The process of Bayesian network model building was assisted by a dental expert. <br/><b>Results</b> - The model allows to identify probabilistic relationships among the variables and to indicate the most significant risk factors of dental caries in three-year-old children. The Bayesian network model analysis illustrates that cleaning teeth and falling asleep with a bottle are the most significant risk factors of dental caries development in three-year-old children, whereas socioeconomic factors have no significant impact on the condition of teeth. <br/><b>Conclusions</b> - Our analysis results suggest that dietary and oral hygiene habits have the most significant impact on the occurrence of dental caries in three-year-olds.

Aim According to the World Health Organization (WHO), early childhood caries (ECC) is still considered a major global health problem despite the general improvement in oral health practice. This study aimed to assess ECC’s prevalence, severity, and key social and behavioral determinants in Iranian children 1–5- years of age. Method This cross-sectional study recruited Iranian 1–5-year-olds with a three-stage stratified clustered sampling method. After providing consent, parents were interviewed using a validated questionnaire, including questions on child characteristics and behavioral factors. Each child underwent a dental examination by one of four trained and calibrated dentists. Associations between key covariates of interest and primary outcome measures were assessed by multivariable logistic regression modeling and multivariate generalized negative binomial regression modeling after weightings were applied. Statistical analysis was performed using SPSS V25 and Stata V14.2 software packages. A p-value ≤ 0.05 was considered significant. Results The mean age of 909 participants was 41.1±1.2 months, 48.6% were male, and 38.1% lived in rural areas. The overall prevalence of ECC was 53.2% and mean dmft score was 2.7± 0.3. Key determinants associated with ECC included living rurally (p = 0.009, OR = 2.13), consuming sweet drinks, sugary snacks, or both [p-value = 0.02 (OR = 2.53), and p-value<0.001 (OR = 4.96), respectively], and visible plaque (p<0.001, OR = 3.41). Covariates associated with dmft scores included residing in rural regions (p = 0.02, IRR = 1.31), having both sugary snacks and sweet drinks (p = 0.02, IRR = 1.85) compared to those had none, and visible dental plaque (p<0.001, IRR = 2.06). Conclusions The prevalence of dental caries in children is high in Iran. The increase of ECC prevalence and severity from toddlers to preschoolers emphasizes on the critical importance of early interventions in toddlers. Improving access to care for rural children is essential along with the need to change dietary and self-care behaviors through multilevel efforts.

ABSTRACT Objective: To test the hypothesis that malocclusion does not have an independent and negative effect on quality of life of adolescents. Materials and Methods: The cross-sectional design study comprised a sample of 519 children, aged 11 to 14 years, attending public schools in Osorio, a city in southern Brazil. One calibrated examiner carried out clinical examinations and recorded dental caries (decayed/missing/filled teeth), malocclusion (Dental Aesthetic Index), and dental trauma. Participants completed the Brazilian version of the Child Perceptions Questionnaire (CPQ11–14), Impact Short Form, and their parents or guardians answered questions about socioeconomic status. Simple and multivariate linear regressions were performed to assess covariates for the overall CPQ11–14 scores. Results: Greater impacts on oral health–related quality of life were observed for girls (P = .007), children with a lower household income (P = .016), those living in nonnuclear families (P &lt; .001), and those with more decayed/missing/filled teeth (P = .001). Malocclusion was also associated with oral health–related quality of life: the severity of malocclusion was significantly related to higher scores of CPQ11–14 even after scores were adjusted for control variables. CPQ11–14 increased by approximately 1 point for each increase in the severity of malocclusion. Conclusions: Malocclusion has a negative effect on adolescents' quality of life, independent of dental caries or traumatic dental injuries. Socioeconomic inequalities and clinical conditions are important features in adolescents' quality of life.

Objectives: The aim of this study was to consider the potential association between the formation of bucall mucusa streptococcus biofilms and a high DMFT index, as well as the occurrence of antibiotic resistance among adult patients in Sana'a, Yemen. Study design: A total of 100; 34-85 year old. Clinical examinations of patients were performed to estimate dental caries experience with the Silness-Loe index, as well as bucall mucusa swabs were collected to assess biofilm production by the phenotypic method, i.e., tissue culture palate methods (TCPM). Finally, the antibiogram susceptibility pattern of isolated S. mutans was done by the Kirby-Bauer disc diffusion method for L-Lactam antibiotics (as ampicillin and penicillin) and non-L-Lactam antibiotics (clindamycin, erythromycin, lincomycin, and vancomycin). Results: When isolated S. mutans were exposed to biofilm detection by the TCP method, 1 (1.2%) showed strong biofilm formation capacity, 71 (86.6%) showed moderate biofilm formation capacity, and 10 (12.2%) showed non/weak formation capacity of biofilm. There was an escalation in the rate of formation of S. mutans biofilms with an increased degree of caries index. The S. mutans biofilms positively showed a higher rate of resistance than non/weak biofilm formation, e.g., ampicillin (91.1% versus 8.9%, p <0x7E> 0.0001), tetracycline (87.8% versus 12.2%, p <0x7E> 0.0001), and co-trimoxazole (90%% versus 10%, p <0x7E> 0.0001), etc. Conclusion: The present study proved that S. mutans is still the major bacteria isolated from the oral cavity, but few persons might not have a significant number of S. mutans in the oral cavity. The S. mutans biofilm producers were more able to cause dental caries compared to the S. mutans biofilm non-producers. Drug-resistant factor in the S. mutans isolates was found to be associated with S. mutans biofilm formation.

OBJECTIVE: To evaluate the association of school failure among Brazilian adolescents with social conditions and aspects of oral health through hierarchical analysis. METHODS: A state-wide survey of 5,558 adolescents from the state of São Paulo, Brazil, inquired about the sociodemographic and social capital of participants by using a structured questionnaire. Trained and calibrated professionals performed intraoral examinations and interviews in the households. Questions about the access to dentist, reason for and frequency of using dental services, toothache episodes and impact of oral conditions on daily activities (OIDP) were applied. Oral examinations evaluated caries experience, tooth losses, periodontal problems, presence of open bite, and maxillary and mandibular overjet. School failure was estimated according to the teenagers’ years of schooling. The independent variables were grouped into three blocks: sociodemographic and economic characteristics, social capital and oral health aspects. The multiple hierarchical logistic regression model was used to identify the factors associated with school failure. RESULTS: Of the total sample, information about schooling of 5,162 adolescents was obtained, of whom 29.6% presented school failure. We found that adolescents over the age of 16 years who did not declare themselves as white, female, with feelings of insecurity, unhappiness, with toothache, caries, tooth losses, affected by dentofacial and/or periodontal changes, were more likely to fail at school. CONCLUSION: Oral disorders and social factors were associated with school failure in adolescents. A successful school trajectory was a strong determinant of health, therefore actions between the educational and health sectors must be developed for adolescents, especially those with this profile.

Pregnant women have one of the highest risks of dental disease [3]. According to a number of authors, during the physiological course of pregnancy, the prevalence of dental caries is 91.4%, periodontal tissue diseases occur in 90% of cases, lesions of previously intact teeth with a predominantly acute course of the carious process - in 38% of pregnant patients [5 ]. Secondary caries, progression of the carious process, enamel hyperesthesia occurs in 79% of pregnant women [11]. At the same time, the intensity of the increase in dental caries in terms of the absolute increase in the index of caries-filling-removal during the gestational period is 0.83 [2]. In 50% of pregnant women and women in labor, the so-called gingivitis of pregnant women is observed during the normal course of the gestational period already at 2-3 months of pregnancy [12]. From the second half of pregnancy, the pathological process becomes more pronounced and more often proceeds as a generalized catarrhal or hypertrophic gingivitis, and pyogenic granuloma often develops. As pregnancy progresses, periodontal disease progresses continuously, and only in the postpartum period does the clinical picture improve [4]. In the long term, gingivitis that occurs during pregnancy becomes chronic [9, 10]. In a pregnant woman, against the background of altered reactivity and reduced body resistance, latent odontogenic foci of infection can lead to serious complications as a result of exacerbation of the inflammatory process [7, 8]. The greatest severity of inflammatory phenomena in periodontal tissues occurs in the second trimester of pregnancy, and the critical increase in the cariogenic situation in the oral cavity occurs in the third trimester [4, 2], which not only determines the optimal timing of dental examinations during pregnancy and the postpartum period, but also the differentiation of the approach to programs for the prevention and treatment of the most significant diseases of the oral cavity for this period of pregnancy. The decisive role in the development of caries and periodontitis in pregnant women belongs to hormonal substances (somatomammotropin, progesterone, gonadotropin) produced by the placenta, changes in mineral and protein metabolism, immunological status, oral microflora [1, 5]. The timing of the increased risk of the onset and progression of periodontal diseases, as well as the increase in the intensity of dental caries in pregnant women, is not enough to state; tires. This does not negate the significance of already established factors affecting the occurrence and development of dental caries, periodontal disease during pregnancy, but is aimed at competently combining diagnostically important known and newly identified criteria into a system of practical recommendations for identifying risk groups among pregnant women. on dental health and special monitoring of them. Immunoprotective peptides of biological media, including oral fluid, are markers of the intensity of local inflammation and are responsible for the implementation of innate antimicrobial immunity [6, 12]. In the oral fluid, a whole complex of immunoprotective peptides is isolated, among which lactoferrin, cathelicidin LL-37, and α-defensin are distinguished [14]. The inclusion of immunoprotective peptides in algorithms and models for ranking the risk of progression of dental caries during pregnancy will expand the boundaries of existing recommendations in this direction. When studying systemic immunity in pregnant women with periodontal diseases, oral fluid and peripheral blood are used as biological media [8]. At the same time, retroplacental blood and umbilical cord blood containing fetal and maternal blood, despite the easy method of selection after the birth of a child and placenta, not associated with invasive manipulations, is not used as a biological medium. Meanwhile, the determination of the spectrum of inflammatory mediators, the mineral composition of retroplacental and umbilical cord blood will allow answering the questions whether inflammation of the periodontal tissues of varying severity was accompanied by the "mother-placenta-fetus" system, whether it is possible to predict from the stage of childbirth in the future the appearance of caries of milk teeth? The purpose of this study is to optimize the system of providing dental care to pregnant women using clinical and laboratory indicators.
