Effect of dental caries and socioeconomic status on social capital throughout adolescence: a 6-year follow-up

Relationship among different levels of individual and community social capital with oral health related-quality of life among adolescents

AIM

To evaluate the relationship of different levels of social capital with oral health-related adolescents' quality of life (OHRQoL).

METHODS

This is a cross-sectional study nested in a cohort study started in 2010 with a sample of children 1 to 5 years old from Brazil. Individuals were followed after 10 years, data which was considered in this study (11 to 15 years old). OHRQoL was evaluated by the short version of CPQ11-14. Individual social capital (ISC) was assessed through the presence of individual social networks and social trust. Community social capital (CSC) was assessed through the presence of voluntary institutions, community cultural centers or residents' associations. For both ISC and CSC, the participants were classified as with high social capital (at least one source) or low social capital (absence of any source). Adjusted Poisson Regression analysis was performed to verify the interaction of different levels of social capital and OHRQoL. Results are present in Rate Ratio (RR) and 95 % confidence interval (95 % CI).

RESULTS

A total of 429 adolescents were evaluated. Adolescents with low CSC and low ISC presented CPQ11-14 scores 36 % higher (RR 1.36 95 %CI 1.15-1.62) than counterparts who presented higher social capital levels. The interaction among high and low levels of social capital was not associated with CPQ11-14 scores, indicating that no level stands out over the other.

CONCLUSION

Only the total absence of both levels of social capital negatively related with OHRQoL, indicating the importance of the presence of at least one source of social capital.

CLINICAL RELEVANCE

The findings show that social capital affects OHRQoL, a crucial psychosocial aspect considering the clinical practice.

Factors affecting oral health in children and adolescents in Ecuador

Globally, the highest prevalence of caries in permanent teeth is found in the Andean region of Latin America. In countries such as Ecuador, the burden of oral diseases has shown an increase in recent years. The present study aimed to identify the risk factors associated with dental pain in children and adolescents aged 5 to 18 years in Ecuador, in order to base preventive actions to improve oral health in this population. Using the database of the National Health and Nutrition Survey, a sample of 23,621 participants was analyzed. The analysis included variables such as ethnic self-identification, region of residence, housing area, and maternal educational level, in addition to the economic impact of dental pain. The results showed that approximately one third of children and adolescents experienced dental problems that affected their quality of life in the last 12 months. The data revealed that dental pain, difficulties in chewing, speaking, and sleeping, as well as school absences due to dental problems, were common. Significant differences were found in the impact on quality of life associated with ethnicity, region, area of residence and maternal educational level. Residents of rural areas, indigenous people and children of mothers with basic education had a higher prevalence of dental problems. The conclusions highlight the need to develop preventive strategies adapted to risk groups, promoting specific interventions to reduce dental pain and improve oral health

A randomized controlled trial of 6-month dental home visits on 24-month caries incidence in preschool children

OBJECTIVES

This paper reports on the effect of 6-month dental home visits compared to no dental home visits on 24-month caries incidence in 5- to 6-year-olds.

METHODS

5- to 6-year-olds attending kindergartens were randomized to receive either 6-month dental home visits and education leaflets (Intervention group) or education leaflets alone (Control group) over 24 months. To detect a 15% difference in caries incidence with a significance level of 5% and power of 80%, 88 children were calculated to be needed in the Intervention group and 88 in the Control. Baseline clinical data included oral examinations at the kindergartens. Follow-up visits were made on the 6th, 12th and 18th month. At the end of the 24 months, both the Intervention and Control groups were visited for oral examinations. The primary outcome was caries incidence, measured by the number and proportion of children who developed new caries in the primary molars after 24 months. The secondary outcome was the number of primary molars that developed new caries (d-pms). Frequency distributions of participants by baseline socio-demographic characteristics and caries experience were calculated. The chi-square test was used to test differences between the caries experience in the Intervention and Control groups. The t test was used to compare the mean number of primary molars developing new caries between the Intervention Group and the Control Group. The number of children needed to treat (NNT) was also calculated.

RESULTS

At the 24-month follow-up, 19 (14.4%) developed new caries in the Intervention Group, compared to 60 (60.0%) in the Control Group (p = .001). On average, 0.2 (95% CI = 0.1-0.3) tooth per child in the Intervention Group was observed to have developed new caries compared to 1.1 (95% CI = 0.8-1.3) tooth per child in the Control Group (p = .001). The number of children needed to treat (NNT) to prevent one child from developing new caries was 2.2.

CONCLUSIONS

The present study has demonstrated that 6-month home visits to families of 5- to 6-year-olds are effective in caries prevention in 5- to 6-year-olds of low-income families in a middle-income country where access to health services, including oral health promotion services, is limited.

The Impact of Parental Education on Schoolchildren's Oral Health-A Multicenter Cross-Sectional Study in Romania

The present study is part of the first national oral health survey for children in Romania. The aim of this study was to determine caries prevalence in correlation with the level of the parents' education, preventive behavior, and socioeconomic parameters in 11-14-year-old schoolchildren in Romania. A cross-sectional epidemiological survey was designed and conducted in 2019-2020. The sampled children were selected from 49 schools distributed in rural and urban areas of Romania, including its capital. Data were collected using the Oral Health Questionnaire for Children developed by the World Health Organization and described in the WHO Oral Health Surveys-Basic Methods, 5th edition, 2013, after positive informed consent. To express prevalence and severity of carious lesions, International Caries Detection and Assessment System (ICDAS) criteria were recorded in school for 814 schoolchildren (388 boys and 426 girls) aged between 11 and 14 years old (mean age 12.29 ± 0.6). Elements regarding the specificity of the child (gender, age, and parental education) were tabulated against preventive behavior. The parents' education was correlated with three clinical indices in order to assess the existence or lack of certain significant differences among schoolchildren in Romania. In terms of correlation between the mother's education and preventive behavior, results showed a significant positive correlation in case of dental check-ups (r_s = 0.08 *, p < 0.05), brushing (r_s = 0.02 **, p < 0.01), and use of different types of dental hygiene aids (r_s = 0.06 **, p < 0.01) and a negative correlation with tooth pain or discomfort (r_s = -0.01 **, p < 0.01). A statistically significant positive relationship was highlighted between the mother's education and the presence of restorations (r_s = -0.09 **, p < 0.01). Regarding the father's education, there was a positive relationship with oral hygiene behavior (r_s = 0.18 **, p < 0.01) but a negative relationship with the D₃T index (r_s = -0.18 **, p < 0.01). In conclusion, there was a strong correlation between the parents' education, preventive behavior, and oral health status of Romanian schoolchildren.

Sense of coherence moderates the relationship between social capital and oral health‑related quality of life in schoolchildren: a 10-year cohort study

Background

This study aimed to evaluate the moderating effect of sense of coherence (SOC) on the relationship between social capital and oral health-related quality of life (OHRQoL) among schoolchildren.

Methods

A cohort study was conducted in the city of Santa Maria, Brazil, involving children aged 1–5 years at baseline who were reassessed after 10 years in adolescence (11–15 years-old). Social capital was assessed at baseline and follow-up through social networks and social trust. Sense of coherence scale (SOC-13) and the short form of the Child Perceptions Questionnaire 11–14 (CPQ11–14) were measured at 10-years follow-up. Demographic and socioeconomic characteristics, and dental caries were also evaluated. Moderating effect of SOC on the relationship between social capital and OHRQoL was tested using multilevel adjusted Poisson regression analysis and simple slope test.

Results

From the 639 subjects assessed at baseline, 429 were reassessed at follow-up (cohort retention rate 67.1%). Moderate and high levels of SOC demonstrated a moderating effect on the relationship between social capital and OHRQoL. Among individuals who presented low social capital at baseline and follow-up, those who had high SOC reported, respectively, an impact 63% and 70% lower on OHRQoL when compared to those with low SOC. The greatest margin effect was observed in individuals with low social capital and low SOC at follow-up (24.25; p < 0.05).

Conclusion

Our findings suggest that SOC moderates the negative impact of low social capital on poor OHRQoL in schoolchildren.

Self-Reported Dental Caries by Mexican Elementary and Middle-School Schoolchildren in the Context of Socioeconomic Indicators: A National Ecological Study

The objective of the present research was to quantify the association between dental caries self-report and socioeconomic indicators in Mexican children. An ecological study included a self-report of dental caries in schoolchildren enrolled in public elementary and middle schools derived from the National School Health Survey. A total of 73,560 schoolchildren (representing 19,745,366 students) aged 5 to 16 years were included. Socioeconomic variables included were scales depicting physical characteristics of housing, purchasing power, etc. used in national surveys in Mexico to measure deprivation, poverty, and income inequality in official data. Data were analyzed in Stata using Spearman's correlation test. For the most part, no association (p > 0.05) was found between caries self-report, socioeconomic variables, or the Gini index. However, caries self-report in elementary schoolchildren and total (elementary + middle-school) schoolchildren groups was positively correlated (p < 0.05) with two poverty variables: extreme poverty by income (value of personal food purchases per month) and poverty by income (value of personal food and non-food purchases per month). National data for dental caries self-report were associated-at the ecological level-with a few socioeconomic indicators but not with most of the usual and customary indicators used in national surveys in Mexico.
