Abstract
Dental caries is a prevalent chronic disease among adolescents. Caries activity increases significantly during adolescence due to an increase in susceptible tooth surfaces, immature permanent tooth enamel, independence in pursuing self-care, and a tendency toward poor diet and oral hygiene. Dental caries in permanent teeth is more prevalent among adolescents in low-income families and racial/ethnic minority groups, and these disparities in adolescent dental caries experience have persisted for decades. Several conceptual and data-driven models have proposed unidirectional mechanisms that contribute to the extant disparities in adolescent dental caries experience. Our objective, using a literature review, is to provide an overview of risk factors contributing to adolescent dental caries. Specifically, we map the interactive relationships of multilevel factors that influence dental caries among adolescents. Such interactive multilevel relationships more closely reflect the complex nature of dental caries experience among the adolescent population. The methods that we use are two-fold: (1) a literature review using PubMed and Cochrane databases to find contributing factors; and (2) the system dynamics approach for mapping feedback mechanisms underlying adolescent dental caries through causal loop diagramming. The results of this study, based on the review of 138 articles, identified individual, family and community-level factors and their interactions contributing to dental caries experience in adolescents. Our results also provide hypotheses about the mechanisms underlying persistence of dental caries among adolescents. Conclusions Our findings may contribute to a deeper understanding of the multilevel and interconnected factors that shape the persistence of dental caries experience among adolescents.

Hwang I, Park K, Park HK. Prevalence of dental caries and associated factors of detention center inmates in South Korea compared with Korea National Health and Nutrition Examination Survey (KNHANES) respondents: a retrospective study. BMC Oral Health 2022; 22:383. [PMID: 36064674 PMCID: PMC9446535 DOI: 10.1186/s12903-022-02405-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 08/19/2022] [Indexed: 11/27/2022] Open
Abstract
Background Correctional institution inmates have reduced access to dental care; however, a quantitative assessment of their oral health condition has not yet been performed in South Korea. Therefore, this study aimed to assess dental caries and compare the prevalence of dental caries and associated factors between inmates and the general South Korean population. Methods The dental records of two detention centers in South Korea were retrospectively analyzed to assess the clinical oral health condition of inmates using the Decayed, Missing, and Filled Teeth (DMFT) index and self-reported questionnaire. These data were compared with similar data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) for the general South Korean population. Results In total, 642 inmates were analyzed and compared with 13,345 KNHANES participants in the KNHANES. The inmate and KNHANES groups demonstrated significant intergroup differences, with a higher prevalence of untreated caries, DMFT, decayed teeth (DT), and missing teeth (MT) values among the inmates. The prevalence of untreated caries decreased according to the history of dental pain in the inmate group but increased in the KNHANES group. The decrease in DMFT with a history of dental pain was significant only in the inmate group. Furthermore, self-rated oral health was significantly associated with prevalence of untreated caries, DMFT, DT, MT, and filled teeth (FT) in the inmate group but with prevalence of untreated caries, DMFT, DT, and MT in the KNHANES group. It was found that this is because there is an interaction effect by the group. Conclusions The oral health of the inmate group was significantly poorer than that of the general group. Since DMFT, DT, MT, and FT values and prevalence of untreated caries in the inmate group were significantly related to their self-rated oral health, suggesting that self-rated oral health should be incorporated into the dental health screenings of correctional institution inmates.

[PMID: 35300666 PMCID: PMC8932162 DOI: 10.1186/s12903-022-02105-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 02/25/2022] [Indexed: 11/13/2022] Open
Abstract
Background Obesity and dental caries among children and adolescents are growing worldwide public health problems. They share some common and modifiable influences. The objective of this study was to evaluate the prevalence of obesity and dental caries among children and adolescents in Huizhou and explore the association between Body Mass Index (BMI) category and dental caries. Methods This cross-sectional study enrolled 105,181 students (55,500 males and 49,681 females) from 87 schools in Huizhou. Height and weight were measured, and BMI was calculated. Based on Chinese BMI standards, students were classified into underweight, normal weight, overweight, and obesity groups. Dental caries was diagnosed according to criteria recommended by World Health Organization (WHO). We used the Chi-square test to compare proportions of groups and performed Association Rules Mining to identify patterns and combinations of BMI categories and dental caries. Finally, a multilevel logistic regression model was applied to analyze the association between BMI category and dental caries when confounders were considered. Results The prevalence of underweight, overweight, and obesity among children and adolescents was 7.56%, 8.85%, and 2.95%, respectively. The overall prevalence of dental caries was 58.10%, with a lower prevalence among boys than girls. Students from primary schools and remote towns more easily suffer from dental caries. Caries prevalence of students belonged to underweight, normal, overweight, and obesity was 65.6%, 58.8%, 49.6%, and 46.1% individually. With increasing BMI levels, the prevalence of dental caries decreased. Further, this trend still exists in each subgroup of gender, educational stage, school type, and area. Association rules indicate underweight has a positive effect on the occurrence of dental caries, while overweight or obesity has a negative impact on the occurrence of dental caries. The three-level logistic regression model results show that BMI category is inversely associated with dental caries after adjusting confounders. Conclusion Obesity is negatively associated with dental caries among children and adolescents in Huizhou. Further research is required to investigate how dietary habits, oral hygiene habits, and parental socioeconomic status mediate the association between BMI and dental caries.

Abstract
OBJECTIVE To investigate whether oral health literacy (OHL) and school context are associated with untreated dental caries on the anterior teeth of adolescents. METHODS A representative cross-sectional study was conducted with 746 students aging 15 to 19 in the city of Campina Grande, Brazil. The guardians answered a questionnaire addressing sociodemographic data and the absence/presence of private health insurance. Two examiners were trained for the diagnosis of dental caries using the Nyvad criteria and the measurement of OHL using the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) (Kappa > 0.80). Contextual aspects of the schools were obtained from the 2017 National School Census. Descriptive statistics were conducted, followed by unadjusted and adjusted robust negative binomial regression for complex samples (p < 0.05). RESULTS The average number of anterior teeth with untreated caries was 0.95 (SD = 1.77). Among individual factors, the male sex (RR = 1.64; 95%CI: 1.24–2.16), inadequate level of OHL (RR = 2.03; 95%CI: 1.13–1.63), marginal level of OHL (RR = 1.87; 95%CI: 1.05–3.33) and not having private health insurance (RR = 1.34; 95%CI: 1.07–1.68) were associated with untreated caries on anterior teeth. Among school contextual factors, the number of students in the classroom (RR = 2.64; 95%CI: 1.78–3.93), number of public oral health services in the district (RR = 0.14; 95%CI: 0.05–0.39) and average income of the district in which the school is located (RR = 0.99; 95%CI: 0.98–0.99) were associated with the outcome. CONCLUSIONS Sociodemographic factors, having private health insurance, OHL, and school context exerted an influence on the occurrence of untreated dental caries on anterior teeth in adolescents aging 15 to 19.

[PMID: 33405262 DOI: 10.1111/jphd.12371] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Revised: 02/17/2020] [Accepted: 04/16/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND The purpose of this survey was to examine the association of general characteristics, oral health knowledge, attitudes, behavior, and dental caries status among adolescents in Jiangxi Province and to provide a basis for future prevention of dental caries among middle school students. METHODS A total of 8,160 adolescents aged 12 to 15 years were invited to participate in this survey by a stratified random cluster sampling method from 30 schools in five counties in Jiangxi Province. A self-administered questionnaire was used to understand their basic characteristics, including oral health behaviors, knowledge, and attitudes. Chi-square tests were used to compare dental caries status and general characteristics. Univariate and multivariate logistic regression analyses were used to study the effects of oral health knowledge, attitudes, and behavior on dental caries. RESULTS The prevalence of dental caries in permanent teeth was 25.8 percent, and the mean DMFT score of 12- to 15-year-old adolescents was 0.48 ± 1.04. The prevalence in rural areas was higher than that in urban areas (P < 0.001). The prevalence was higher in girls than in boys (P < 0.001). No significant age differences were observed (P > 0.05) in the prevalence of dental caries. The multivariate logistic regression analysis indicated that the variables associated with dental caries were tooth brushing frequency, use of toothpaste, frequency of sugary milk intake, smoking, and oral health attitudes. CONCLUSIONS This study revealed that adolescent oral health behaviors and attitudes were associated with dental caries. It is important to implement targeted oral disease prevention and control measures among adolescents.

Abstract
BACKGROUND The aim of this study was to evaluate the correlation between caries, body mass index (BMI) and occlusion in a sample of pediatric patients. METHODS The study group included 127 patients (72 female, 55 male) aged between 6 and 16 years (mean age 10.2) and selected between January and June 2019 at the Department of Pediatric Dentistry, University of Messina. Caries incidence was evaluated using the decayed, missing and filled teeth (DMFT) index. On the basis of BMI values, using a table adjusted for age and gender, patients were grouped into four categories (underweight, normal weight, risk of overweight, overweight). RESULTS There was no significant correlation between BMI and DMFT in the whole sample. The study of the correlation between BMI and DMFT in patients with different types of malocclusion showed a significant inverse correlation for patients affected by II class and deepbite malocclusion. CONCLUSIONS The incidence of caries does not seem to be significantly related to BMI and occlusal patterns, but it decreases with increasing age.

Abstract
The aim of the present study was to investigate whether the ability to recognize and read oral health terms is associated with the number of teeth with cavitated carious lesions in adolescents. A population-based cross-sectional study was conducted involving a sample of 746 adolescents representative of students aged 15 to 19 years at the public and private school systems in a city in northeast Brazil. Two examiners who had undergone a training and calibration exercise (inter-examiner and intra-examiner Kappa coefficient: 0.87 to 0.93) performed the diagnosis of caries using the Nyvad Index and evaluated the level of OHL (BREALD-30) of the adolescents. The participants answered questions regarding their history of visits to the dentist and the parents/caregivers answered a questionnaire addressing socioeconomic characteristics. A directed acyclic graph was created to direct the selection of covariables for adjustments in the Poisson multiple regression analysis to test the association between dental caries and OHL (α = 5%). Cavitated carious lesions (codes 3 to 6 on the Nyvad index) were found in 41.6% of the adolescents. Only 29.4% had a high level of OHL (BREALD-30 scores between 23 and 30); 42.3% of the families belonged to the A-B social class and 93% of the adolescents had been to the dentist at least once in their lifetimes. In the multivariate analysis, adolescents with inadequate (PR: 1.69; 95% CI: 1.18–2.41; p = 0.004) and marginal (PR; 1.42; 95% CI: 1.01–1.99; p = 0.042) OHL and those in the lower social classes (C-D-E) (PR: 1.85; 95% CI: 1.39–2.47; p<0.001) had more teeth with cavitated carious lesions. In conclusion, adolescents aged 15 to 19 years with poorer levels of OHL had a larger number of teeth with cavitated carious lesions, independently of their socioeconomic status and history of visiting a dentist.

Abstract
Background: Minorities’ diminished returns (MDRs) refer to systemically weaker effects of socioeconomic status (SES), particularly educational attainment, on the health of non-Whites compared to Whites. Aim: Using a nationally representative sample, we aimed to investigate ethnic differences in the effect of SES (educational attainment) on the self-rated oral health of Hispanic older adults in the US. Methods: This study analyzed the University of Michigan National Poll on Healthy Aging (UM-NPHA) 2017 data, which included 2131 older adults who were 50 to 80 years old (202 Hispanics and 1929 non-Hispanics). Ethnicity, race, educational attainment (SES), age, gender, employment, retirement, and self-rated oral health (single item) were measured. Logistic regressions were applied for data analysis. Results: High educational attainment was associated with lower odds of poor oral health in the pooled sample, net of all covariates. The effect of educational attainment on poor self-rated oral health was found to be weaker for Hispanics than for non-Hispanics. Conclusion: We observed MDRs of educational attainment (SES) on oral health for Hispanic older adults. In other words, compared to non-Hispanics, Hispanics gain less oral health from their educational attainment (SES).

Abstract
OBJECTIVES The objective of this study was to evaluate the combined risk of oral problems in the oral health-related quality of life (OHRQoL) of adolescents aged 15 to 19 years in São Paulo state (Brazil) in the year of 2015. MATERIALS AND METHODS Data from the São Paulo State Oral Health Survey (SBSP-15) and the contextual characteristics of the cities of São Paulo state, evaluated in the year 2015 were accessed. Correlations were made between contextual factors (i.e., coverage of the family health team, average supervised tooth brushing, number of first dental appointments, and average income), individual sociodemographic variables (i.e., ethnicity, gender, and schooling) and dental problems (dental pain, caries, overjet, open bite, indication for endodontic and exodontic treatment, gingival bleeding, and dental trauma). These variables were correlated with the quality of life of the adolescents using the Oral Impacts on Daily Performance (OIDP) index. Multilevel Poisson regressions were performed to calculate the rate ratio (RR) with 95% confidence interval (CI). RESULTS According to the bivariate analysis, the presence of low (RR, 1.62; 95% CI 1.07-2.46) and very intense (RR, 2.53, 95% CI 1.92-3.34) dental pain, indication for endodontic (RR, 1.31; 95% CI 1.05-1.63) or for exodontic (RR, 1.31; 95% CI 1.06-1.63) treatment, and gingival bleeding (RR, 1.41; 95% CI 1.11-1.80) reduced the quality of life of adolescents. All domains of OIDP scores were associated between healthy and unhealthy individuals (p < 0.001) increasing mean scores with combined oral health problems. Higher impact on quality of life was associated with simultaneous presence of dental pain, gingival bleeding, and indication for exodontic treatment (RR, 6.03; 95% CI, 4.02-9.04) in the adolescents. CONCLUSION Individual and contextual factors and the various dental problems are independently associated with the quality of life of Brazilian adolescents aged 15 to 19 years, especially when they are associated with the perception of intense dental pain, gingival bleeding, and indication for exodontic treatment, with up to six times greater impact on OIDP. CLINICAL RELEVANCE The study highlighted the importance for an integral treatment in adolescents, considering that the associated risk of several dental diseases can progressively affect the quality of life of this population.

Abstract
Background. Processes of antioxidant protection in different ethnicities, living in the same geographical conditions, are of undoubted scientific interest. The ratio of activity of oxidative processes and antioxidant components not only reflects, but also largely determines the metabolism and adaptive capabilities of the organism. The key issue in understanding the regulatory and adaptive role of lipid peroxidation reactions in the body is the idea of the existence of a certain balance with the antioxidant defense system.Aims: to study the features of the system of lipid peroxidation and antioxidant protection in adolescents of different ethnicities, living in Eastern Siberia.Materials and methods. Parameters of lipid peroxidation and antioxidant protection were determined in the blood serum by spectrophotometric methods.Results. We found that adolescent Buryat boys had statistically significant decrease in primary and secondary products of lipid peroxidation: ketodienes and conjugated trienes, malondialdehyde, and components of antioxidant protection: retinol, α-tocopherol, the level of total antioxidant activity of blood and reduced glutathione, in comparison with Caucasian adolescents. In Caucasian adolescents with endocrine disorders, there was a statistically significant increase in the level of ketodienes and conjugated trienes, as well as the activity of superoxide dismutase against the background of a decrease of reduced glutathione, tocopherol, and retinol. We revealed a significant increase in the concentration of ketodienes and conjugated trienes and a decrease of the oxidized glutathione in adolescents with endocrine disorders in comparison with healthy adolescents of Buryat ethnicity.Conclusions. Studying of the processes of lipid peroxidation and antioxidant system of the organism can be used as an additional criterion for complex examination of practically healthy adolescents, which significantly enhance the representation about the adaptation possibilities of the organism to external conditions and can become a basis for effective examination of reproductive health in the future.
