The relationship between dental caries and sense of coherence (SOC) has not been substantiated in children and adolescents, particularly among those with a low socioeconomic status. The aim of this study was to investigate the association between SOC and dental caries in schoolchildren from a low socioeconomic background. A random sample of 356 8- to 14-year-old schoolchildren enrolled in public schools from the poorest region of Santa Maria, a southern city in Brazil, was selected. Dental examinations were performed to assess dental plaque and dental caries (DMF-S and dmf-s indexes). The children’s SOC was assessed using a validated Brazilian version of the SOC-13 scale. Socioeconomic, demographic, and behavioral data were collected from parents using a questionnaire. Multilevel Poisson regression analysis was used following a hierarchical approach to investigate the association between the SOC and DMF-T + dmf-t mean. Children whose mothers had studied for 8 years or less (RR 1.30; 95% CI 1.08–1.57) and children with dental plaque (RR 1.29; 95% CI 1.06–1.58) presented with higher DMF-T scores than their counterparts (p < 0.05). A higher household income (RR 0.66; 95% CI 0.51–0.84) and greater SOC scores (RR 0.71, 95% CI 0.56–0.90) were associated with lower DMF-T in children (p < 0.05). Children’s SOC seems to be a relevant protective psychosocial factor for dental caries experience in socially vulnerable children.

The Dental Aesthetic Index (DAI) was determined in 12- and 15-year-old schoolchildren to ascertain the prevalence of malocclusion and to assess its association with dental caries experience, dental plaque accumulation, and socio-demographic variables. We performed a cross-sectional study with a stratified two-stage sampling design. An oral health survey and oral examination were conducted, and socio-demographic data were recorded. The sample comprised 1453 schoolchildren aged 12 (868) and 15 (585). These two samples were analyzed separately because statistically significant differences were found: the 12-year-old age group displayed a higher frequency of schoolchildren who attended state-run public schools (p = 0.004) and belonged to a lower social class (p = 0.001); the 15-year-old age group registered higher levels of caries (p = 0.001) and lower levels of dental plaque (p < 0.001). The malocclusion was 9.5% higher (p = 0.001), and the global mean DAI score was likewise higher among the 12-year-olds (p < 0.001). The multivariate regression analysis not only showed that caries and dental plaque were the variables that were the most strongly associated with malocclusion, but that caries (OR = 1.5) and dental plaque (OR > 2) were also risk factors for malocclusion in both groups. In conclusion, this study revealed a higher prevalence of malocclusion and dental plaque at age 12. A higher risk of caries and dental plaque was found to be related to the presence of malocclusion in both age groups.

Aim: Although children spend most of their time involved in activities related to school, few studies have focused on the association between school social environment and oral health. This cross-sectional study assessed individual and school-related social environment correlates of dental caries in Brazilian schoolchildren aged 8-12 years. Methods: A sample of children from 20 private and public schools (n = 1,211) was selected. Socio-economic data were collected from parents, and data regarding children characteristics were collected from children using a questionnaire. Dental examinations were performed to assess the presence of dental plaque: dental caries experience (DMFT ≥1) and dental caries severity (mean dmf-t/DMF-T). The social school environment was assessed by a questionnaire administered to school coordinators. Multilevel Poisson regression was used to investigate the association between school social environment and dental caries prevalence and experience. Results: The dental caries prevalence was 32.4% (95% confidence interval: 29.7-35.2) and the mean dmf-t/DMF-T was 1.84 (standard deviation: 2.2). Multilevel models showed that the mean dmf-t/DMF-T and DMFT ≥1 were associated with lower maternal schooling and higher levels of dental plaque. For contextual variables, schools offering after-hours sports activities were associated with a lower prevalence of dental caries and a lower mean of dmf-t/DMF-T, while the occurrence of violence and theft episodes was positively associated with dental caries. Conclusions: The school social environment has an influence on dental caries in children. The results suggest that strategies focused on the promotion of healthier environments should be stimulated to reduce inequalities in dental caries.

Survival analyses have been used to overcome some of the limitations encountered with other statistical analyses. Although extended Cox hazard modeling with time-dependent variables has been utilized in several medical studies, it has never been utilized in assessing the complex relationship between mutans streptococci (MS) acquisition (time-dependent covariate) and time to having dental caries (outcome). This study involved secondary analyses of data from a prospective study conducted at the University of Alabama at Birmingham. Low socioeconomic status, African-American preschool children from Perry County, AL, USA (n = 95) had dental examinations at age 1 year and annually thereafter until age 6 years by three calibrated dentists. Salivary MS tests were done at ages 1, 1.5, 2, 2.5, 3, and 4 years. The patterns of and relationship between initial MS detection (time-dependent covariate) and dental caries experience occurrence were assessed, using extended Cox hazard modeling. The median time without MS acquisition (50% of the children not having positive MS test) was 2 years. Approximately 79% of the children had positive salivary MS tests by the age of 4 years. The median caries experience survival (50% of the children not having dental caries) was 4 years. During the follow-up period, 65 of the children (68.4%) had their initial primary caries experience. Results of the extended Cox hazard modeling showed a significant overall/global relationship between initial caries experience event at any given time during the follow-up period and having a positive salivary MS test at any time during the follow-up period (hazard ratio = 2.25, 95% CI 1.06-4.75). In conclusion, the extended Cox modeling was used for the first time and its results showed a significant global/overall relationship between MS acquisition and dental caries. Further research using causal mediation analysis with survival data is necessary, where the mediator “presence of MS” is treated as a time-dependent variable.

AbstractObjective:To identify the key features of a nutrition resource that are important to adolescents of a low socioeconomic status (SES).Design:Structured interviews were conducted to explore participants’ preferences relating to the features of a nutrition resource. Thematic framework analysis was used to determine key themes, subthemes and concepts from the data.Setting:Streetsport activity sessions, north-east of Scotland.Participants:Eighteen adolescents aged 12–17 years from a low socioeconomic background.Results:The overarching themes identified were barriers and facilitators to engagement with a nutrition resource. Adolescents expressed a preference for an app, and this was mainly attributed to convenience and low cost. There was also an emphasis on the integral role social media has in their lives. Aesthetics was a facilitator for both male and female participants, with a particular focus on weight loss. Behaviour change support, including reminders, access to simple recipes and adopting a ‘small change approach’, were identified as possible facilitators, whereas cost, environmental influences, and existing eating habits were identified as possible barriers to engaging with a nutrition resource.Conclusions:A number of subthemes, including aesthetics, cost and convenience, which have previously been reported in adolescents with a higher SES, were prominent in our research. The present study contributes to insights relating to behaviour change tools that should be considered when developing a nutrition resource targeting disadvantaged adolescents. Further research focusing on how mobile phone technology and social media can be utilised to support dietary behaviour change in low SES adolescents is recommended.

Dental caries is a complex disease process that afflicts a large proportion of the world's population, regardless of gender, age and ethnicity, although it does tend to affect more indivduals with a low socioeconomic status to a greater extent. The process of dental caries is dependent upon biological factors that are present within the saliva and dental plaque. There are many different agents within saliva and plaque that serve to protect the tooth surface against caries development. Salivary flow rate, buffering capacity, antimicrobial activity, microorganism aggregation and clearance from the oral cavity, immune surveillance, and calcium phosphate binding proteins all interact to inhibit or reverse demineralization of exposed tooth surfaces. Cariogenic bacteria levels within the saliva and plaque determine whether caries will occur or not, and the concentration in saliva and plaque are intimately related to the type of carbohydrate ingestion and the frequency of ingestion, as well as the oral hygiene practiced by the individual.

Abstract In 2017, Chicago Public Schools adopted an online universal application system for all high schools with the hope of providing more equitable access to high-performance schools. Despite the new system, Black students and students living in low-socioeconomic status (SES) neighborhoods remained less likely than their peers to enroll in a high-performance high school. In this paper, we characterize various constraints that students and families may face in enrolling in a high-performance high school including eligibility to programs based on prior academic achievement, distance from high-performance options, elementary school performance ratings, and neighborhood SES. After adjusting for differences in these access factors, we find the gap between Black and Latinx students’ likelihood of enrolling in a high-performing high school is reduced by about 80 percent. We find a similarly large reduction in the enrollment gap between students from low- and middle-SES neighborhoods after adjusting for eligibility and distance factors. These findings have implications for policies that may help equalize access to highperformance schools through changes to eligibility requirements and improved transportation options.

ObjectivesWe examined the trend in the number of missing teeth in a Japanese community over a 10-year period and the potential associated explanatory factors.DesignProspective cohort study.SettingA population-based study conducted in 2007, 2012 and 2017 in Japan (Hisayama Study).ParticipantsResidents of a Japanese community aged 40–79 years undergoing dental examination in 2007 (n=2665), 2012 (n=2325) and 2017 (n=2285).Outcome measuresThe number of missing teeth, periodontal condition, dental caries experience, dental plaque index and oral health behaviours were evaluated each year. The longitudinal analysis of variation in these factors were assessed using mixed models.ResultsThe age-adjusted and sex-adjusted mean number of missing teeth decreased with time (6.80 in 2007, 6.01 in 2012 and 4.99 in 2017). The mean clinical attachment level (CAL), prevalence of periodontitis and dental plaque index decreased over the study period, while dental caries experience slightly increased. The level of oral health behaviour increased over time. Poisson mixed models showed that changes in mean CAL and dental caries experience were positively associated with the change in the number of missing teeth over time. Linear mixed models showed that changes in dental plaque index and no regular dental visit were positively associated with changes in mean CAL.ConclusionsThese findings suggest that a decreasing trend regarding the number of missing teeth in Japan might be associated with improvements in the periodontal condition due to changes in oral hygiene level and oral health behaviour.

This article explores the effect of meeting opportunities between local urban and nonlocal residents on locals’ prejudice against migrant children in China by focusing on three contexts: friendships, schools, and neighborhoods. China’s hukou policy creates a boundary between urban and rural residents, which also takes the form of locals and nonlocals in rural-to-urban migration. Urban public schools with a mix of local and migrant students offer a chance to observe the intergroup relationships between local and nonlocal students as well as their parents. Using the two waves of data of the China Education Panel Survey (CEPS), this study examines how changes in the migrant friends, schoolmates, and neighbors of local children affect changes in their parents’ prejudice among a sample of 1,630 student-parent pairs. With longitudinal data, this study mitigates the effect of reverse causality between intergroup contact and prejudice. The findings show that parents whose children have more migrant friends have less prejudice, under certain conditions. Additionally, more nonlocal students in the school are related to less prejudice, especially among parents who are more embedded in the school. Furthermore, local families with low socioeconomic status experience an increase in prejudice, potentially due to an increased feeling of threat. Besides, this article finds that prejudiced attitudes spread through the social networks of children and parents at the school level. This study emphasizes the importance of different contexts of meeting opportunities and sheds new light on the generalizability of the contact hypothesis to the understudied context of Chinese internal migration.

ABSTRACT The tongue microbiota of elderly adults is composed of two cohabiting commensal groups and their ratios are related to the number of teeth with dental caries experience. In this study, the variation in the tongue microbiota of primary school children and its relationship with the dental caries experience were investigated. We examined the tongue microbiota of 138 children aged 6 to 7 years and 11 to 12 years (61 and 77 children, respectively) who underwent annual dental examinations. The bacterial composition was determined by sequencing the V1-V2 region of the 16S rRNA gene. Cooccurrence network analysis indicated two groups of cohabiting predominant commensals in the tongue microbiota of children. The microbiota in children without a history of dental caries showed significantly higher relative abundances of one of the cohabiting groups, primarily composed of Neisseria subflava, Porphyromonas pasteri, and Fusobacterium periodonticum, compared to that in children with a history of dental caries, which is consistent with that of elderly adults with fewer teeth with dental caries experience. Linear discriminant analysis effect size (LEfSe) further identified Streptococcus oralis subsp. dentisani, belonging to the aforementioned commensal group, as a discriminant species in children without dental caries experience aged 6 to 7 years and 11 to 12 years. Our results describe the tongue microbiota composition of primary school children without history of dental caries and support the possibility that dental caries experience is accompanied by a shift in the tongue microbiota. IMPORTANCE Dental caries is now considered to be caused by acids produced by the overall dental plaque microbiota rather than by specific pathogens. This study focused on the relationship between dental caries experience and the variations in tongue microbiota, which is adjacent but separate from the dental plaque microbiota. Our results demonstrated that the tongue microbiota of primary school children with no history of dental caries experience was composed of predominant commensals with different relative abundances compared to those present in children with dental caries experience, suggesting that dental caries experience is accompanied by a shift in the tongue microbiota. The maintenance of a healthy tongue microbiota may indirectly contribute to the prevention of dental caries.
