Assessing individual and neighborhood social factors in child oral health-related quality of life: a multilevel analysis

Association of children's oral health and school environment on academic performance in 12-year-old schoolchildren of Quito, Ecuador

OBJECTIVES

The primary aim of this study was to evaluate if children's oral health and oral health-related quality of life (OHRQoL) were associated with school performance. Moreover, the study aimed to examine whether school environment factors influenced this association.

METHODS

This cross-sectional study was based on a population-based sample of 998 12-year-old schoolchildren from 31 public schools in Quito, Ecuador. Trained and calibrated examiners conducted clinical exams for dental caries, dental trauma and malocclusion. Furthermore, children completed the Spanish version of the Child Perception Questionnaire (CPQ11-14 ), and their parents answered questions about socio-economic status. School coordinators provided information on the physical environment, promotion of health practices and the occurrence of negative episodes in the school. There were three outcomes: grades obtained in Spanish language and mathematics and the number of missed school days. Multilevel linear and Poisson regression models were conducted using a hierarchical approach to include the variables guided by a previously created direct acyclic graph.

RESULTS

Children with dental trauma and higher CPQ11-14 scores showed lower grades and school attendance. Schoolchildren from schools with episodes of vandalism had more school days missed.

CONCLUSION

The school performance of 12-year-old children is affected by dental trauma and by a worse OHRQoL, as well as a negative school environment. Therefore, supportive environments and promoting health measures in schools could overcome this worse academic performance in children with oral health problems.

Dental caries and oral health-related quality of life in Preschoolers - introducing the Swedish version of the early childhood oral health impact scale (ECOHIS)

OBJECTIVE

Experience of caries has a clearly negative impact on the quality of life in preschool children. The instrument Early Childhood Oral Health Impact Scale (ECOHIS) measures the oral health-related quality of life in preschool children (Child Impact Section) and their families (Family Impact Section). The aims of the study were to develop a Swedish version of ECOHIS and to evaluate the instrument's reliability, validity, and internal consistency. Additionally, to analyse the oral health-related quality of life (OHRQoL) among preschool children who have experienced caries.

METHODS

The original ECOHIS questionnaire was translated into Swedish. Caregivers of preschool children aged 2-5 years were recruited at dental clinics in Sweden, to participate in the study and answer the Swedish version of the ECOHIS (S-ECOHIS). The internal consistency and reliability were assessed by using Cronbach's Alpha coefficient. In order to measure the consistency of the study, the questionnaire was re-tested two weeks later for 10 of the caregivers and assessed by using intra-class correlation coefficients (ICCs). The results from S-ECOHIS were described as descriptive data and independent t-test was performed. All data were calculated using SPSS (Statistical Package for the Social Sciences).

RESULTS

S-ECOHIS was developed by translating the original English version using a double-blinded technique. A total of 274 caregivers participated in the study and completed the questionnaire. Cronbach's Alpha was 0.84 for S-ECOHIS, 0.83 for CIS, and 0.66 for FIS. The ICCwas 0.95 for the test-retest of S-ECOHIS. Among the respondents, 117 (43%) had children diagnosed with caries, while 157 (57%) had children without caries. The children with caries reported a higher total score of 5.97 (SD 6.16) of S-ECOHIS, compared to the score of the non-caries children 0.77 (SD 1.38) (p < 0.001).

CONCLUSION

The Swedish version of ECOHIS that was developed demonstrates good validity, test-retest reliability, and internal consistency. The findings show that the oral health-related quality of life is adversely affected in preschool children with caries, with particular vulnerability observed among children with untreated caries. These results indicate that S-ECOHISis suitable for use in future clinical and research endeavors.

Associations between psychological stress, discrimination, and oral health-related quality of life: the buffering effects of social support networks

Stress and discrimination negatively affect quality of life, but social support may buffer their effects. This study aims: (1) to examine the associations between psychological stress, discrimination, and oral health-related quality of life (OHRQoL); and (2) to assess whether social support, stress and discrimination interact to modify their associations with OHRQoL. We used cross-sectional household-based data from a study including 396 individuals aged 14 years and over from families registered for government social benefits in a city in Southern Brazil. OHRQoL was measured with the Oral Impacts on Daily Performance (OIDP) scale; psychological stress was assessed with the Perceived Stress Scale (PSS); social support was assessed based on the number of close relatives or friends of the participant, and discrimination was assessed with a short version of the Everyday Discrimination Scale. Interactions were estimated using the relative excess of risk due to interaction (RERI). Adjusted effects were calculated with logistic regression. The prevalence of oral impacts among people with higher and lower PSS scores was 81.6% and 65.5%, respectively (p < 0.01). Social support was found to have no interactions with stress levels and discrimination. The association between social discrimination and OHRQoL (OIDP score > 0) was OR = 2.03 (95%CI: 1.23; 3.34) among people with a low level of stress, but was OR = 12.6 (95%CI: 1.31; 120.9) among those with higher levels (p = 0.09, for interaction). Individuals who reported experiencing higher levels of psychological stress and discrimination had worse OHRQoL; a synergistic effect with social support was not clear.

The Impact of Socioeconomic Factors on Pediatric Oral Health: A Review

This narrative review examines the impact of socioeconomic status (SES) on pediatric oral health, emphasizing disparities in dental caries prevalence and oral health-related quality of life (OHRQoL) among children from different socioeconomic backgrounds. Utilizing an extensive literature search through PubMed, Google Scholar, and the chat.consensus.app plugin, we synthesized findings from studies published up to December 2023. The review highlights a consistent association between lower SES and adverse pediatric oral health outcomes, influenced by parental education, household income, food security, and neighborhood conditions. It also underscores the importance of the life-course perspective, showing how early-life socioeconomic disadvantages can have long-lasting effects on oral health. Furthermore, the review points to the critical role of school-based oral health education programs and the complex interplay between mental health, SES, and pediatric oral health. By examining the impact of socioeconomic factors across different childhood stages and the effectiveness of educational interventions, this review calls for targeted interventions and policy initiatives aimed at reducing socioeconomic inequalities in pediatric oral health. The findings advocate for a multifaceted approach to improve oral health outcomes for children across socioeconomic backgrounds, ensuring equitable access to oral health care and promoting overall well-being.

Social capital and possible bruxism during the COVID-19 pandemic among Brazilian undergraduates

This study investigated the prevalence of possible bruxism and its association with social capital among undergraduates during the coronavirus disease (COVID-19) pandemic. This cross-sectional study was conducted at a private university in Southern Brazil. Data were collected through a self-administered electronic questionnaire (Google Forms). Possible bruxism was measured using the following question: "Do you grind your teeth or clench your jaws?". Social capital was evaluated using individual social networks. Data on self-perceived oral health, anxiety, sociodemographics, and information related to university graduates were also collected. Adjusted logistic regression models with a hierarchical approach were used to evaluate associations. The results are presented as odds ratios (ORs) and 95% confidence intervals (95%CIs). Altogether, 345 undergraduates participated in the study, with a mean age of 21.8 years (standard deviation = 5.21). The prevalence of bruxism in the sample was 57.1%. Undergraduates with low social capital had 2.06 times greater odds of bruxism than their counterparts (OR 2.06; 95%CI 1.11-3.83). Female undergraduates (OR 2.40, 95%CI 1.39-4.12), those who were in the final year of university (OR 1.13, 95%CI 1.04-1.21), and those who perceived they needed dental treatment (OR 1.91; CI: 1.21-3.02) also had greater odds of possible bruxism. In conclusion, the prevalence of possible bruxism was high among undergraduate students during the COVID-19 pandemic and associated with lower social capital levels. Knowledge of these factors is important to identify risk groups and plan strategies to control bruxism in this population.

Clustering of children's oral diseases in families and villages in a rural setting in Egypt

BACKGROUND

This study assessed the clustering of children' caries experience, plaque accumulation and gingival inflammation in families and villages in Northwestern Egypt and the factors related to the severity of these conditions.

METHODS

This was a secondary analysis of a 2019 household survey of children in villages around Alexandria, Egypt. Clinical examination assessed primary and permanent teeth caries experience (dmft/ DMFT using the World Health Organization criteria), plaque accumulation (Plaque Index (PlI)) and gingival inflammation (Gingival Index (GI)). A child questionnaire assessed child's age, sex, the frequency of toothbrushing (at least twice daily versus less) and frequency of consuming eight types of sugary products (daily sugar consumption score, sum of sugary products consumed daily). Mothers' questionnaire assessed the number of children in the family, mother's education (at least high school versus less), at least twice daily toothbrushing and daily sugar consumption similar to the child. Multilevel regression analyses assessed clustering, calculated by the intraclass correlation coefficient (ICC) of the three conditions in families and villages. Regression estimates (B) and 95% confidence intervals (CIs) of individual and family factors were calculated.

RESULTS

Complete data were available for 450 children (246 families, seven villages], mean = 9.9 years-old and 56% females. The mean caries experience score = 3.6, mean plaque index = 1.5 and mean gingival index = 1.2. Caries experience, plaque accumulation and gingival inflammation were not clustered in villages (ICC < 0.01) but clustered in families (ICC = 0.10, 0.44 and 0.29). Child factors significantly improved model fit for caries experience and gingivitis (p < 0.001) but not plaque accumulation (p = 0.90). Family factors did not improve any model fit (p > 0.05). Child's age was significantly associated with caries experience (B= -0.48, p < 0.001) and gingival inflammation (B = 0.032, p < 0.001). Children who brushed their teeth twice daily had significantly more caries experience (B = 1.04, p = 0.01).

CONCLUSION

The three oral conditions were not clustered in villages but clustered in families. Plaque accumulation showed the greatest within-family clustering. Family factors were not associated with the three conditions and individual factors indicated the need for interventions to promote preventive behaviors and identify families at risk of oral conditions.

Impact of the use of dental services on dental pain according to adolescents' skin colour: a 10-year cohort

OBJECTIVE

Evaluate the association of the interaction between the use of dental services and the skin colour on the occurrence of dental pain over time.

MATERIAL AND METHODS

This study is a cohort with 10 years of follow-up, started in 2010 with a sample of 639 preschool children (1-5 years old). The use of dental services, race and the presence of dental pain were self-reported by the individuals according to predefined criteria. Multilevel logistic regression analysis was performed to assess the interaction between skin colour and use of dental services in the occurrence of dental pain over time.

RESULTS

About 449 and 429 were reassessed in 2017 and 2020, respectively. The occurrence of dental pain across the cohort was 60.7%. Caucasian individuals who used dental services throughout the cohort had a 51% lower chance of having a dental pain than those who used dental services but were non-white (OR 0.49; 95% IC 0.27-0.90).

CONCLUSION

There was a racial inequity in the occurrence of dental pain among individuals who managed to make use of dental services throughout the follow-ups.

CLINICAL RELEVANCE

The differences found should serve as a warning to the way how individuals with different characteristics are treated and must be used to combat this inequity. Individuals should receive resolute and personalized treatments according to their clinical condition and not according to their socioeconomic characteristics.

Social capital and oral health in children and adolescents: A systematic review and meta-analysis

OBJECTIVES

To systematically evaluate the association of individual and contextual social capital with oral health outcomes in children and adolescents.

METHODS

Electronic searches were performed in PubMed/Medline, Embase, Web of Science and Scopus databases for articles published from 1966 up to June 2021. Two calibrated reviewers screened and critically appraised the identified papers. Observational studies that evaluated the relationship of individual or/and contextual social capital or their proxies with oral health outcomes in children and adolescents using validated methods were included. Quality assessment was conducted using the Newcastle-Ottawa Scale. Data were extracted for narrative synthesis and meta-analysis followed by a meta-regression model. Meta-analysis using random effects method was used to estimate pooled prevalence ratio (PR) and 95% confidence intervals (CI).

RESULTS

Of the 3060 studies initially retrieved, 31 were included in the systematic review and 21 in the meta-analysis, totalling 81 241 individuals. The clinical outcomes included dental caries and gingival bleeding and subjective outcomes were oral health-related quality of life (OHRQoL) and self-rated oral health (SROH). Individuals with lower levels of individual social capital had a higher prevalence of poor clinical (PR 1.11; 95%CI 1.02-1.22) and subjective (PR 1.25; 95%CI 1.09-1.45) oral health conditions. The prevalence of worse clinical (PR 1.34; 95%CI 1.11-1.61) and subjective (PR 1.56; 95%CI 1.13-2.16) oral health outcomes were also associated with lower levels of contextual social capital. In general, the contextual level of social capital exerted more impact, and the subjective oral health outcomes were the more affected.

CONCLUSIONS

Contextual and individual social capital were positively related to oral health outcomes, such as dental caries, gingival bleeding, SROH and OHRQoL in children and adolescents.

Social capital and oral health promotion: Past, present, and future challenges

Social capital has been widely inserted in health discussions in recent decades. In this sense, social capital has become a popular term and has been highlighted as one of the main determinants of health in the conceptual framework of the social determinants of the World Health Organization. The concept of social capital focuses on the positive consequences of sociability and places these consequences in the broader discussion of capital. In this sense, social capital reflects the benefits that individuals and communities derive from having broad social networks or high levels of social trust. Despite controversies regarding its definition and numerous criticisms, a growing body of evidence suggests that high levels of social capital benefit oral health. This factor has also been recognized as a potential softener of the impact of oral conditions on oral health, through behavioural and psychosocial processes. Thus, efforts to reduce inequities in oral health preferably should be based on their origins and on their complex causal process, such as the social determinants. The future challenges in the area are specially related to the development of interventions and health promotion actions that aim to stimulate social capital, aiming to reduce the impact of social inequalities on oral health throughout the life course.

Premature Primary Tooth Loss and Oral Health-Related Quality of Life in Preschool Children

The present study aimed to evaluate the association between premature primary tooth loss and oral health-related quality of life (OHRQoL) in preschool children. A cross-sectional study was conducted in 769 5-year-old preschool children. The children and their parents or guardians answered the Brazilian version of the Scale of Oral Health Outcomes for 5-Year-Old Children for the assessment of OHRQoL. Meanwhile, clinical examinations were performed for the assessment of premature primary tooth loss. Unadjusted and adjusted multilevel Poisson regression models were utilized to investigate the associations between the variables. In the parental version of the scale, premature posterior primary tooth loss (rate ratio [RR] = 2.65; 95% confidence interval [CI] = 1.51-4.68), weak sense of coherence (RR = 2.25; 95% CI = 1.62-3.11), and visit to a dentist (RR = 1.61; 95% CI = 1.04-2.52) were associated with OHRQoL. Based on the children's perceptions, only the preschool type was associated with OHRQoL (RR = 1.92; 95% CI = 1.21-3.05). Premature posterior primary tooth loss had a greater impact on OHRQoL based on the parents' perception, whereas only the preschool type was associated with OHRQoL based on the children's perception.

Impact of community and individual social capital during early childhood on oral health-related quality of life: A 10-year prospective cohort study

AIM

To evaluate the impact of community and individual social capital during early childhood on oral health-related quality of life (OHRQoL) over a 10-year follow-up period.

METHODS

A prospective cohort study was conducted in the southern Brazil. Baseline (T1) data collection occurred in 2010 with preschool children aged 1-5 years. Participants were assessed in 2012 (T2), 2017 (T3), and 2020 (T4). OHRQoL was assessed using the B-ECOHIS at T1 and T2 and through CPQ8-10 at T3 and CPQ11-14 at T4. Community social capital was evaluated through the presence of formal institutions in the neighbourhood and individual social capital by social networks, both at T1. Demographic and socioeconomic characteristics were also evaluated. Multilevel Poisson regression analysis was performed to estimate the impact of social capital measures on OHRQoL.

RESULTS

Of the 639 children assessed at T1, 469 were followed at T2 (73.3% response rate), 449 at T3 (70.3% response rate), and 429 at T4 (67.1% response rate). Individuals living in neighbourhoods with the presence of social class associations at T1 had higher OHRQoL at T3 and T4. Individuals whose families visit friends and neighbours less than once a month or never at T1 had lower OHRQoL at T1, T3 and T4. Attending religious meetings less than once a month or never at T1 was associated with lower OHRQoL at T2 and T4.

CONCLUSION

Social capital at the community level had a long-term effect on OHRQoL, especially during adolescence, while individual social capital levels impacted OHRQoL across the assessments.

CLINICAL SIGNIFICANCE

The findings indicate that psychosocial variables can impact OHRQoL, a fundamental aspect of clinical practice.

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.

Impact on oral health-quality of life in infants: Multicenter study in Latin American countries

To assess the impact of oral conditions on oral health-related quality of life (OHRQoL) in infants in ten Latin America countries (LAC). A cross-sectional study was conducted with 930 pairs of 1-to-3-year-old children/parents from 10 LAC, as a complementary study of the Research Observatory for Dental Caries of the Latin American Region. The scale ECOHIS, previously tested and valid in ten countries, was applied to parents/caregivers of children to measure OHRQoL. Statistical analysis included descriptive data analysis and one-way analysis of variance (ANOVA-One-Way) were performed to compare age groups with OHRQoL. Bootstrapping procedures (1000 re-samplings; 95%CI Bca) were performed. The mean scores of the ‘Child Impact’ section in the LAC was 4.0(±8.3), in the ‘Family Impact’ section was 2.0(±4.0), and in overall ECOHIS score was 6.0(±12.0). In the ‘Child Impact’ section, Argentina 10.0(+2.4) and Venezuela 17.8(±17.5) demonstrated mean scores higher than the LAC total data. In the ‘Family Impact’ section, the countries with higher mean scores were Argentina 4.9(±2.0), Ecuador 2.1(±3.1) and Venezuela 7.9(±7.8). In the overall ECOHIS score, Argentina 15.1 (±4.1) and Venezuela 25.7(±25.2) has higher mean scores than the values of LAC. There is an association between children's age and parents' report of impact on the OHRQoL (p<0.001). Three-year-olds had a higher mean when compared to one- and two-year-olds, both in the Impact on the Child and Impact on the Family (p<0.001) sections, as well as in the overall ECOHIS (p<0.001). In conclusion, there are differences in OHRQoL among Latin American countries, impacting older children more significantly.

Oral health-related quality of life (OHRQOL) of preschool children's anterior teeth restored with zirconia crowns versus resin-bonded composite strip crowns: a 12-month prospective clinical trial

OBJECTIVES

To compare oral health-related quality of Life (OHRQOL) of preschool children's anterior teeth restored with prefabricated zirconia crowns (ZC) versus resin-bonded composite strip crown (RCSC).

MATERIALS AND METHODS

A prospective clinical trial included 136 children with early childhood caries aged 36-71 months who were assigned into prefabricated ZC and RCSC groups. A total of 344 teeth were restored either with 170 ZCs (49.4%) and 174 RCSCs (50.6%). Wilson and Cleary's conceptual model was to associate the study predictors to the OHRQOL. Early Childhood Oral Health Impact Scale (ECOHIS) was used to assess the OHRQOL at 6 and 12 months. Mann-Whitney U test was used in comparing OHRQOL mean scores in the two groups and Wilcoxon signed-rank test with the effect size (r) to measure the intragroup OHRQOL change. A Poisson regression model was used to study potential risk factors associated with the overall OHRQOL.

RESULTS

After 12 months, the USPHS parameters of the ZC were significantly superior compared to the RCSC. Overall ECOHIS mean scores in the ZC group were significantly lower than that of the RCSC group at T₁ and T₂ (p < 0.001). Remarkable enhancement of the OHRQOL at the follow-ups with a large effect size (r < 0.8) was observed. Restoration type, retention, baseline OHRQOL, and color had a significant impact on the overall OHRQOL at 12 months.

CONCLUSIONS

Preschool children OHRQOL treated with ZC were significantly better than those who received RCSC.

CLINICAL RELEVANCE

One of the optimum treatment standards in pediatric dentistry is the esthetic demand which has significance on the child's OHRQOL and subsequently child's general health quality of life. It is beneficial to the dentist to identify the influence of esthetic restorations on the OHRQOL of preschool children which aids in future decision-making. The longitudinal nature of the study enables the dentist to identify the changes of children's OHRQOL.

Prevalence of dental trauma in Brazilian children and adolescents: a systematic review and meta-analysis

This study aimed to investigate the prevalence of dental trauma in Brazilian children and adolescents. A systematic review was conducted considering eight databases: MEDLINE (via PubMed), LILACS, BBO, Scopus, Embase, Web of Science, Open Access Theses and Dissertations, and OpenThesis. Only prevalence studies that used a probabilistic sampling method were included, without restriction on year or language of publication. The JBI critical appraisal tools for prevalence studies were used to assess the individual risk of bias. The individual studies were combined in the meta-analysis using the random-effects model. The heterogeneity between the studies was analyzed by Cochran's Q and the I-square statistics. A meta-regression analysis was performed to evaluate the sources of heterogeneity. The GRADE approach assessed the certainty of evidence across included studies. The search resulted in 2,069 records, of which 36 were included in the study. The eligible studies were published from 2000 to 2021, with a total sample of 40,194 children and adolescents. Most studies (75%) had a low risk of bias. In permanent teeth, the prevalence of dental trauma was 21% (95%CI: 16.0; 26.0) and in deciduous teeth; 35% (95%CI: 26.0; 44.0). The prevalence of dental trauma among boys was higher than among girls for both dentitions. Based on a low certainty, the prevalence of traumatic dental injuries in Brazilian children and adolescents is higher than that found worldwide both in deciduous and permanent teeth. Also, the prevalence of dental trauma among boys is higher than among girls.

Pathways influencing dental caries increment among children: A cohort study

BACKGROUND

Dentists should assess pathways influencing the increment of dental caries among children to guide the prevention and treatment of the disease.

AIM

Evaluate the pathways that influence the increment of carious lesions in pre-school children.

DESIGN

This is a 2-year cohort study was conducted with a random sample of 639 pre-school children in southern Brazil. Caries experience, socioeconomic status (SES), social capital, and psychosocial characteristics were obtained at baseline. Increment of dental caries was assessed at 2 years follow-up in 467 children (cohort retention rate of 73.1%). Previously calibrated examiners assess the caries through the International Caries Detection and Assessment System (ICDAS). Structural equation modeling (SEM) was performed to test the pathways influencing dental caries increment.

RESULTS

Dental caries at baseline was heavily influenced by children's age (SC: 0.381, P < .01), tooth plaque (SC: 0.077, P = .02), parent's perception child oral health (SC: 0.295, P < .01), and household (SC: 0.148, P < .01). Increment of dental caries was directly affected by dental caries at baseline (Standardized Coefficients [SC]: 0.377, P < .01). Indirect paths were not significant.

CONCLUSIONS

Dental caries experience was the main factor of direct influence on the increment of caries, reinforcing the theory of risk accumulation over time.

Cross-cultural adaptation and psychometric properties of the Mexican version of the Early Childhood Oral Health Impact Scale (ECOHIS)

BACKGROUND

Instruments adapted for the Mexican population to assess oral health-related quality of life (OHRQoL) in preschoolers remain lacking. This study aimed to cross-culturally adapt and evaluate the psychometric properties of the Mexican version of the Early Childhood Oral Health Impact Scale (M-ECOHIS).

METHODS

This cross-sectional study was conducted with preschool children from southern Mexico. The investigation was divided into a transcultural adaptation phase and a validation phase. The M-ECOHIS was completed by the children's guardians, and clinical data were also evaluated. Reliability was evaluated using tests of internal consistency and test-retest measures, while construct validity was assessed through Spearman's correlation coefficient between M-ECOHIS scores and self-reported oral health, and through confirmatory factor analysis (CFA). Construct validity was also evaluated through discriminant validity of the M-ECOHIS, which was determined according to questionnaire scores on oral health measures (e.g., dental caries).

RESULTS

A total of 303 preschool children participated in this study. Regarding internal consistency, Cronbach's alpha was > 0.78 for the child section, family section, and general M-ECOHIS. The general intraclass correlation coefficient (ICC) for test-retest reliability was 0.95. The correlation between the scores obtained on the child and family impact sections was significant with the self-reported oral health status rating. In relation to CFA, all items of the M-ECOHIS confirmed the latent variables. Further, M-ECOHIS scores were associated with the presence of untreated dental caries, indicating that the questionnaire has good discriminant validity.

CONCLUSION

Our findings suggest that the M-ECOHIS is a valid and reliable instrument for assessing the impact of oral health on quality of life in Mexican preschool children.

Effect of individual and neighborhood social capital on gingival bleeding in children: A 7-year cohort study

BACKGROUND

Social capital incorporates contextual and individual levels of interactions, which influence human health. The aim of this study was to evaluate the influence of individual and contextual social capital in early childhood on gingival bleeding in children after 7 years.

METHODS

This 7-year cohort study was conducted with a randomized sample of 639 children (1 to 5 years old) evaluated in 2010 (T1) in Santa Maria, southern Brazil. Gingival bleeding was recorded during follow-up (T2). Contextual (social class association and number of churches) and individual (religious practice, volunteer networks, and school involvement) social capital variables were collected at baseline, along with demographic, socioeconomic, and oral health variables. A multilevel Poisson regression model was used to investigate the influence of individual and contextual variables on mean gingival bleeding. The incidence rate ratio (IRR) and 95% confidence interval (95% CI) were calculated.

RESULTS

A total of 449 children were reassessed after 7 years (70.3% cohort retention rate). Children living in areas with a larger number of churches at baseline had lower mean gingival bleeding at follow-up. Regarding individual social capital, children whose parents did not attend school activities were more likely to have gingival bleeding. Additionally, low maternal education, poor parents' perception of oral health, non-use of dental services, and low frequency of tooth brushing were related to higher mean gingival bleeding at follow-up.

CONCLUSION

The presence of more churches in neighborhoods and parents' involvement in a child's school activities positively influenced children's oral health, and these individuals had lower mean gingival bleeding.

Socioeconomic status and oral health-related quality of life: A systematic review and meta-analysis

OBJECTIVES

To systematically review observational studies assessing the association between socioeconomic status (SES) and oral health-related quality of life (OHRQoL) in children, adolescents and adults.

METHODS

Electronic searches were performed in the PubMed, Embase, Web of Science, LILACS and Scopus databases for articles published up to September 2020. Two independent reviewers performed the search and critical appraisal of the studies. The inclusion criteria were observational studies that evaluated the effect of SES on the OHRQoL in all age groups using validated methods. Quality assessment was conducted using the Newcastle-Ottawa Scale. Data were extracted for meta-analysis followed by a meta-regression analysis. A random-effects model was used to estimate the pooled calculate prevalence ratio (PR) and respective 95% confidence intervals (CI) for each study.

RESULTS

The search strategy retrieved 6114 publications. Some 139 articles met the eligibility criteria and were included in the systematic review. Of those, 75 were included in the general meta-analysis they represented a total sample of 109 269 individuals. People of lower SES had worse OHRQoL (PR 1.30; 95% CI 1.26-1.35). In the meta-analyses of different subgroups, an association was found between low SES and worse OHRQoL in countries of all economic classifications, in all age groups and irrespective of the socioeconomic indicator used. A socioeconomic gradient in OHRQoL was also observed, in which the lower the individuals' socioeconomic position, the poorer their OHRQoL.

CONCLUSIONS

Individuals of low SES had poorer OHRQoL, regardless of the country's economic classification, SES indicator and age group. Public policies aiming to reduce social inequalities are necessary for better OHRQoL throughout life.

Factors Affecting Preventive Dental Treatment of Adolescents in Korea

We conducted a multilevel analysis to identify factors affecting adolescents’ preventive dental treatment experience in South Korea. We sampled 72,435 students who participated in the 9th Korea Youth Risk Behavior Web-based Survey. The individual-level variables were divided into demographic factors, socioeconomic factors, oral health behavioral factors, and oral symptom experience factors. The regional-level variables included oral health resources, rate of students receiving oral health education at school by region, social deprivation index, and the number of private educational institutions. A higher rate of receiving oral health education in school by region was associated with increased fluoride application (1.04 times, p = 0.003). However, the number of private educational institutes per 1000 people was negatively associated with fluoride application experienced by students (0.64 times, p = 0.039). Students underwent more scaling when there were more dentists per 10,000 individuals (1.14 times, p = 0.008) and less scaling in areas with a higher social deprivation index (0.88 times, p = 0.024). To increase the access to preventive care for oral diseases among adolescents, a preventive system should be established in schools, and a primary dental care system should be established through the cooperation of the government, private dental clinics, and schools.

Oral status, sense of coherence, religious-spiritual coping, socio-economic characteristics, and quality of life in young patients

BACKGROUND

Several factors can influence the oral health.

AIM

To explore the clinical factors, individual characteristics, and environmental factors (religious-spiritual coping-RSC, sense of coherence [SOC], and socio-economic status) related to oral status and impact on oral health-related quality of life (OHRQoL) of children/adolescents (C/A).

DESIGN

This study evaluated C/A up to 15 years old and their caregivers. Number of decayed (NDT) and missing teeth (NMT); history of dental trauma; caregiver's RSC and SOC, socio-economic factors, and OHRQoL were evaluated. Theoretical model exploring the direct and indirect effects was tested using a structural equation analysis.

RESULTS

For younger group (0-6 years), having more NDT or more NMT had a greater impact on the OHRQoL (β = 0.382, β = 0.203, respectively). In the oldest group (7-15 years), a higher SOC had an inverse relationship with the impact on the family OHRQoL (β=-0.201). The higher the age of the C/A, the lower the NDT (β=-0.235), and the higher the family income the lower, the need for social benefit (β = 0.275). Indirect relationships were observed between schooling with social benefit and OHRQoL in younger group. The family income indirectly influenced the OHRQoL in oldest group.

CONCLUSIONS

Quality of life is affected directly and indirectly by environmental characteristics, oral status, and the age of patients.

Orofacial functions and quality of life in children with unilateral cleft lip and palate

This study aimed to evaluate the orofacial functions and oral health-related quality of life (OHRQoL) of children with unilateral cleft lip and palate (UCLP). This case-control study included patients with UCLP matched by sex and age with controls (children without UCLP), resulting in the inclusion of a total of 108 eight- to ten-year-old children. Orofacial functions and OHRQoL were evaluated using the Nordic Orofacial Test-Screening (NOT-S) and the Child Perceptions Questionnaire (CPQ 8-1 0 ), respectively. Data normality was assessed by the Kolmogorov-Smirnov test. Differences and correlations in NOT-S and CPQ 8-1 0 scores between and within the groups were evaluated using Mann-Whitney and Spearman´s correlation tests, respectively. The distribution of NOT-S and global ratings of CPQ 8-1 0 for each group were assessed by Chi-squared/Fisher's Exact tests. The UCLP group had a higher NOT-S total and examination scores than the controls. Dysfunctions related to breathing, facial symmetry/expression, and speech were more frequent in the UCLP patients than in the controls. The UCLP group had higher scores on the social well-being domain than the controls. There was a significant difference between the groups in their ratings in regards to the extent to which their oral condition affected their life overall, with controls perceiving it as somewhat better than patients. In both groups, NOT-S total and interview scores were positively correlated with CPQ 8-1 0 total and domain scores. The NOT-S examination score was only significantly correlated with social domain scores in the control group. The presence of UCLP was associated with clinical signs of orofacial dysfunctions related to breathing, facial symmetry/expression, and speech. Children with UCLP reported more orofacial dysfunctions and negative impacts on social well-being than controls.

Systematic review of factors influencing oral health-related quality of life in children in Africa

Background

Oral health-related quality of life (OHRQoL) is influenced by cultural and societal context. Existing OHRQoL children measurement tools have been conceptualised in high-income countries. Probing whether the factors influencing OHRQoL are context-reliant in the African setting is necessary and is the purpose of the current review.

Aim

To investigate if the factors influencing OHRQoL are context-reliant.

Methods

Seven databases were searched using search terms (‘oral health’; and ‘quality of life’, ‘health-related quality of life’, ‘patient-reported outcomes’, ‘well-being’; and ‘child*’, ‘adolescents’, ‘teen*’, ‘youth’; and ‘determinants’, ‘factors’, ‘predictors’; and ‘oral health quality of life tools/instruments/scales’; and ‘Africa*’). Abstracts identified were exported to a reference software manager. Three of the authors used specific selection criteria to review, firstly, 307 abstracts and, secondly, 30 full papers. Data were extracted from these papers using a pre-designed data extraction form, after which quantitative synthesis of data was performed.

Results

Key factors influencing OHRQoL followed an existing conceptual framework where environmental and individual factors in the form of socio-economic status (SES), area of residence and children psyche status, and the presence of any oral condition other than dental caries were reported among child populations in Africa.

Conclusion

There is preliminary evidence to suggest an association between individual factors such as children’s psyche and oral problems, excluding dental caries, and environmental determinants such as area of residence and SES in children’s OHRQoL in African children. The finding that dental caries was not a key factor in child-oral health is unexpected. There seemed to be a contextual viewpoint underpinning the current OHRQoL frameworks and OHRQoL was context-reliant.

Socioeconomic inequalities in oral health-related quality of life in adolescents: a cohort study

PURPOSE

Socioeconomic inequalities are recognized as a major problem with people in low socioeconomic groups having worse subjective oral health outcomes, including oral health-related quality of life (OHRQoL). However, only a few longitudinal studies assessed the impact of contextual and individual socioeconomic determinants in adolescents' OHRQoL. We estimate the impact of socioeconomic inequalities on adolescents' OHRQoL over a 2-year period.

METHODS

This study followed up a random sample of 1134 12-year-old schoolchildren for 2 years in Brazil. OHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11- to 14-year-old Children (CPQ11-14) at baseline and follow-up. Participants were clinically examined for dental caries, gingival bleeding, and malocclusion. The schoolchildren's parents answered a questionnaire regarding socioeconomic status, social capital, and adolescents' use of dental service. Socioeconomic contextual variables were collected from official city publications. Multilevel linear regression models fitted the associations between socioeconomic factors and overall CPQ11-14 scores over time.

RESULTS

A total of 747, 14-year-old adolescents were reassessed for OHRQoL (follow-up rate of 66%). Adolescents with lower mean income school's neighborhood (P < 0.05), household income (P < 0.05), and maternal schooling (P < 0.05) had higher overall CPQ11-14 scores. Female sex, attending a dentist by toothache, dental caries, and malocclusion were also associated with higher overall CPQ11-14 scores.

CONCLUSIONS

Adolescents from low socioeconomic background reported worse OHRQoL at 2-year follow-up compared to those from high socioeconomic background. Actions toward health inequalities need to address socioeconomic factors in adolescence.

Prevalence of early loss of primary molar and its impact in schoolchildren's quality of life

BACKGROUND

Evidence regarding the impact of premature loss of primary molars on oral health-related quality of life (OHRQoL) is lacking.

AIM

To evaluate the prevalence of premature loss of primary molars in schoolchildren and its impact on OHRQoL.

DESIGN

We randomly selected 667 children aged 8-9 years enrolled in public and private schools from Aracaju (Brazil). The presence of untreated dental caries and early loss of primary molars were recorded, and its impacts on OHRQoL evaluated using Child Perceptions Questionnaire (CPQ_8-10 ). Influence of some variables on tooth loss and OHRQoL was assessed by multilevel Poisson's regression analysis (P < 0.05).

RESULTS

The prevalence for early tooth loss was 65.4% (95% confidence interval 51.1%-77.3%). Children with untreated dental caries and attending public schools presented higher prevalence of early tooth loss. Moreover, early loss of primary molars provoked negative impact on OHRQoL considering total score of CPQ_8-10 and domains "oral symptoms," "functional limitations" and "emotional well-being." Children presenting early teeth loss presented significantly higher scores of CPQ_8-10 , as well as females and children with dental caries in other teeth.

CONCLUSIONS

The prevalence of early loss of primary molars is high, and it impacts the OHRQoL of children aged 8-9 years.

Contextual and individual determinants of oral health-related quality of life among five-year-old children: a multilevel analysis

Background

Contextual factors may influence oral health-related quality of life (OHRQoL) in children. The aim of the present study was to evaluate the influence of individual and contextual determinants of OHRQoL based on the perceptions of children.

Methods

A cross-sectional study was conducted with a representative sample of 769 five-year-old children from public and private preschools in a city in the countryside of northeast Brazil. Parents/caregivers answered questionnaires addressing psychological aspects, sociodemographic data and aspects of the child’s oral health. The children answered the child version of the Scale of Oral Health Outcomes for five-year-old children and were submitted to oral examinations. Variables related to the context were obtained from the schools and official municipal publications. Unadjusted and adjusted multilevel Poisson regression models were used to investigate associations between variables.

Results

In the adjusted analysis, parent’s/caregiver’s schooling, household income, parent’s/caregiver’s age, a history of dental pain, dental caries and its consequences and traumatic dental injury were considered individual determinants of OHRQoL according to the children’s self-reports. After the incorporation of the contextual determinants, the association between parent’s/caregiver’s schooling and OHRQoL lost its significance. Type of school was the context variable that remained associated with OHRQoL.

Discussion

Besides the clinical and sociodemographic individual characteristics, characteristics of the school environment in which the child studies are associated with self-reported impacts on OHRQoL.

Importance of contextual variables related to cavitated lesions in 5-year-old children

BACKGROUND

Dental caries have a high prevalence in children and need to evaluate their individual and contextual determinants.

AIM

To evaluate the importance of individual and contextual determinants on the occurrence of cavitated lesions in 5-year-old children.

DESIGN

A cross-sectional study was conducted with 769 preschoolers in a city in northeastern Brazil. Parents/caregivers answered questionnaires addressing psychological aspects, socio-demographic characteristics and the child's oral health. The diagnosis of dental caries (cavitated lesion) was performed using the ICDAS-II. Variables related to the context were collected at the preschools and official municipal publications. Unadjusted and adjusted multilevel Poisson regression models with robust variance correction were used.

RESULTS

The prevalence of cavitated lesions was 58.8%. In the analysis adjusted by individual determinants, low household income (PR = 1.61; 95%CI:1.27-2.05), lower parent's/caregiver's schooling (PR = 1.57; 95%CI:1.20-2.05), not visited to the dentist (PR = 0.77; 95%CI:0.62-0.94), brushing frequency under 2 times per day (PR = 2.17; 95%CI:1.35-3.51) and weak parent's/caregiver's SOC (PR = 1.30; 95%CI:1.09-1.56) were associated with cavitated lesions. However, after the incorporation of the contextual determinants, parent's/caregiver's schooling and SOC lost their association. Considering contextual factors, children attending public preschools (PR = 1.66; 95%CI:1.34-2.05) and/or smaller preschools (PR = 1.001; 95%CI:1.001-1.002) had a greater probability of exhibiting cavitated lesions.

CONCLUSION

Contextual variables were more important to the occurrence cavitated lesions than individual socioeconomic variables.

Sensitivity of an oral health-related quality-of-life questionnaire in detecting oral health impairment in preschool children

AIM

This two-year cohort study evaluated whether the Early Childhood Oral Health Impact Scale (ECOHIS) is responsive to detect changes related to dental caries.

DESIGN

Preschool children were examined in 2010 regarding dental caries, and their parents responded to the ECOHIS. After 2 years, 352 children (response rate = 73.6%) were re-examined and a new ECOHIS was responded. Children were categorized according to caries increment (no new caries, 1-3 surfaces with new lesions, and four or more decayed surfaces). The outcome variables were related to the decline of quality of life as determined via ECOHIS: decline, severe decline, and differences between baseline and follow-up scores. Effect sizes (ES) were calculated, and the associations were evaluated through Poisson regression.

RESULTS

ES was small for children with 1-3 new lesions (ES = 0.19) and moderate for children with four or more new carious lesions (ES = 0.61). Children who developed 1-3 new lesions were significantly associated with all outcome variables compared to children with no new lesions, but the associations were stronger for children with four or more new carious lesions.

CONCLUSIONS

The ECOHIS is sensitive to the deterioration of quality of life due to caries increments in preschool children.

Responsiveness of the Early Childhood Oral Health Impact Scale (ECOHIS) is related to dental treatment complexity

BACKGROUND

The responsiveness of the Early Childhood Oral Health Impact Scale (ECOHIS) has varied greatly across studies; hence, we hypothesized that this discrepancy could be related to the complexity of dental treatment received. Thus, we aimed to evaluate the responsiveness of the ECOHIS to changes in oral health-related quality of life (OHRQoL) following dental treatments of varying complexity in preschool children.

METHODS

Preschool children aged 3 to 6 years were selected; their parents responded to the ECOHIS at baseline. The parents responded to the ECOHIS again and a global transition question 30 days after the children were treated. The type of treatment received by the children was categorized according to complexity, as follows: 1) non-operative treatment only, 2) restorative treatment, and 3) endodontic treatment and/or tooth extraction. Change scores and effect sizes (ES) were calculated for total scores, as well as considering the different treatment types and global transition question responses.

RESULTS

Of the 152 children who completed the study, the ECOHIS yielded large ES for total scores (0.89). The children showed increasing ES values associated with better perception of improvement, assessed by the global transition question. The magnitude of ES after treatment was related to treatment complexity (0.53, 0.92 and 1.43, for children who received non-operative treatment only, restorative treatment, and endodontic treatment and/or tooth extraction, respectively).

CONCLUSIONS

Parents whose children required more complex dental treatment are more likely to perceive treatment-related changes to OHRQoL assessed with the ECOHIS.

Social Determinants of Pediatric Oral Health

Social determinants of health are defined as conditions in which people are born and live and the role these conditions play on health outcomes. Research indicates that risk factors and their interactions are far more complex than originally thought. This article outlines social determinant constructs and their role in understanding oral health promotion. Due to the complex interactions, oral health must be promoted using a multilevel chronic disease model or common risk factor approach. An understanding of social determinants is particularly important for the pediatric population because optimum oral health and general health in adulthood are heavily influenced by childhood.

Individual and contextual factors influencing dental health care utilization by preschool children: a multilevel analysis

The effect of contextual factors on dental care utilization was evaluated after adjustment for individual characteristics of Brazilian preschool children. This cross-sectional study assessed 639 preschool children aged 1 to 5 years from Santa Maria, a town in Rio Grande do Sul State, located in southern Brazil. Participants were randomly selected from children attending the National Children's Vaccination Day and 15 health centers were selected for this research. Visual examinations followed the ICDAS criteria. Parents answered a questionnaire about demographic and socioeconomic characteristics. Contextual influences on children's dental care utilization were obtained from two community-related variables: presence of dentists and presence of workers' associations in the neighborhood. Unadjusted and adjusted multilevel logistic regression models were used to describe the association between outcome and predictor variables. A prevalence of 21.6% was found for regular use of dental services. The unadjusted assessment of the associations of dental health care utilization with individual and contextual factors included children's ages, family income, parents' schooling, mothers' participation in their children's school activities, dental caries, and presence of workers' associations in the neighborhood as the main outcome covariates. Individual variables remained associated with the outcome after adding contextual variables in the model. In conclusion, individual and contextual variables were associated with dental health care utilization by preschool children.

Impact of traumatic dental injuries on oral health-related quality of life of preschool children: A systematic review and meta-analysis

Background

Observational studies have suggested that traumatic dental injuries (TDI) can lead to pain, loss of function and esthetic problems, with physical, emotional and social consequences for children and their families. However, population-based studies that investigate the impact of TDI on oral health-related quality of life (OHRQoL) among preschool children are scarce and offer conflicting results. The aim of the systematic review and meta-analysis was to evaluate the impact of TDI on OHRQoL among preschool children (PROSPERO-CRD42015032513).

Methods

An electronic search of six databases was performed in PubMed (MEDLINE), ISI Web of Science, Scopus, Science Direct, EMBASE and Google Scholar, with no language or publication date restrictions. The eligibility criteria were TDI as the exposure variable, OHRQoL as the outcome and a population of children up to six years of age. RevMan software was used for data analysis. Results are expressed as odds ratios with 95% confidence intervals for the total score of the Early Childhood Oral Health Impact Scale (ECOHIS) as well as the scores of the Child Impact Section (CIS) and Family Impact Section (FIS). The random effect model was chosen and heterogeneity was evaluated using the I² test.

Results

2,013 articles were initially retrieved; 1,993 articles were excluded based on title and abstracts; 10 articles excluded after full-text analysis. Ten studies comprising a population of 7,461 preschool children were included in the systematic review and nine studies were included in the meta-analysis. TDI caused a negative impact on OHRQoL based on the overall ECOHIS (OR: 1.24; 95% CI: 1.08–1.43) and CIS (OR: 1.23; 95% CI: 1.07–1.41), but not the FIS (OR: 1.09; 95% CI: 0.90–1.32).

Conclusions

TDI negatively impacted on OHRQoL of preschool children. The present findings indicate the need for TDI prevention and treatment programs in early childhood.

Oral health-related quality-of-life scores differ by socioeconomic status and caries experience

OBJECTIVES

(i) Quantify the relative association between child dental caries experience and maternal-reported child oral health-related quality of life (OHRQoL); (ii) examine whether that association differed according to family socioeconomic status (SES); and (iii) explore whether absolute OHRQoL varied by family SES at similar levels of child caries experience.

METHODS

This study was a cross-sectional analysis of children in southern Brazil (n=456, mean age: 38 months) participating in an existing health centre-based intervention study. OHRQoL impact was quantified as mean score on the Brazilian Early Childhood Oral Health Impact Scale (ECOHIS) and compared over categories of caries experience (dmft: 0, dmft: 1-4, dmft: ≥5). Adjusted ECOHIS ratios between caries categories were calculated using regression modelling, overall and within socioeconomic strata defined by maternal education, social class and household income.

RESULTS

Caries prevalence (dmft >0) was 39.7%, mean ECOHIS score was 2.0 (SD: 3.5), and 44.3% of mothers reported OHRQoL impact (ECOHIS score >0). Increasing child caries experience was associated with worsening child and family quality of life: ECOHIS scores were 3.0 times greater (95% CI: 2.0, 4.4) for children with dmft ≥5 vs dmft=0, a pattern that persisted regardless of family socioeconomic status (P for interaction: all >0.3). However, adjusted for dental status and sociodemographic characteristics, mean ECOHIS scores were lower when reported by mothers of less educational attainment (ratio: 0.7; 95% CI: 0.5, 1.0), lower social class (ratio: 0.7; 95% CI: 0.5, 1.0) or in lower income households (ratio: 0.8; 95% CI: 0.6, 1.3).

CONCLUSION

Dental caries was associated with negative child and family experiences and lower OHRQoL across all social groups; yet, families facing greater disadvantage may report lesser quality-of-life impact at the same level of disease experience. Thus, subjective quality-of-life measures may differ under varying social contexts, with possible implications for service utilization, evaluating oral health interventions, or quantifying disease morbidity in low-SES groups.

Factors associated with Oral Health-Related Quality of Life of preschool children in Southern Brazil

ABSTRACT Objective: The aim of this study was to assess the impact of socioeconomic factors and clinical conditions on the child oral health-related quality of life (COHRQoL) of preschool children. Methods: A cross-sectional study was conducted with a representative sample of 547 children of 0-5-years-old from Santa Maria, RS, Brazil, in 2013. Data were collect in the National Children's Vaccination Day Program by calibrated dentists. Clinical examinations assessed the prevalence of dental caries and dental trauma. Information about children's socioeconomic status was collected through a structured questionnaire answered by parents/caregivers. The COHRQoL was measured using the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). Multivariable Poisson regression models were performed to assess the association between clinical conditions, socioeconomic status and COHRQoL. Results: The prevalence of dental caries and dental trauma were 16.42 % and 22.49%, respectively. Higher means of the ECOHIS were found in older children, those with toothache and those whose mother had lower level of formal education. The clinical conditions that have been associated with negative impact on oral health related quality of life were experience caries (RR 4.12; 95% CI 3.10-5.46) and dental trauma (RR 1.37; 95% CI 1.01-1.86). Conclusion: Poor socioeconomic and clinical conditions had a negative impact on the COHRQoL, indicating the need of preventive strategies and policies aiming at improving the quality of life of this sample.

Influence of initial caries lesions on quality of life in preschool children: a 2-year cohort study

OBJECTIVES

We aimed to assess the impact of the presence of initial and other stages of dental caries on the impairment of oral health-related quality of life in preschool children (COHRQoL) through a cohort study.

METHODS

During an epidemiological survey, 478 children (12-59 months old) were examined for dental caries using the International Caries and Detection Assessment System (ICDAS), and their parents answered the Early Childhood Oral Health Impact Scale (ECOHIS). Children were categorized based on the presence of dental caries as follows: children with no caries lesions, children with only initial lesions (ICDAS scores 1 and 2), children with at least one moderate lesion (ICDAS scores 3 and 4) and children with extensive lesions (ICDAS scores 5 and 6). After 2 years, 352 children were re-examined for the presence of dentine cavitations, and their parents completed a new ECOHIS questionnaire. Multilevel Poisson regression analysis was performed to evaluate the impact of the presence of different stages of caries lesions at the baseline on COHRQoL impairment at the follow-up, considering two outcome variables: worsening and severe worsening of COHRQoL. Relative risk values (RR) and respective 95% confidence intervals (95% CI) were calculated.

RESULTS

Worsening or severe worsening of the COHRQoL at the follow-up were observed only in children with moderate lesions (RR = 2.00; 95% CI = 1.30-3.08 and RR = 2.38; 95% CI = 1.31-4.34, respectively) or children with extensive lesions (RR = 1.59; 95% CI = 1.10-2.30 for worsening and RR = 1.88; 95% CI = 1.13-3.12 for severe worsening). On the other hand, the presence of only initial caries lesions was not a significant predictor of COHRQoL impairment.

CONCLUSIONS

The presence of only initial caries lesions does not impair COHRQoL of preschool children; however, moderate and extensive lesions are risk factors for worsening of the COHRQoL.

The Malay version of the Early Childhood Oral Health Impact Scale (Malay-ECOHIS)--assessing validity and reliability

BACKGROUND

The Early Childhood Oral Health Impact Scale (ECOHIS) is used to assess oral impacts on the quality of life of preschool aged children and their families. The objective of this study was to perform a cross-cultural adaptation of the ECOHIS into Malay and assess its psychometric properties.

METHODS

The cross-cultural adaptation of ECOHIS into Malay comprised of translating the ECOHIS into the Malay language (Malay-ECOHIS) by experts followed by face validation of the Malay-ECOHIS by a group of mothers. The Malay-ECOHIS was back translated into English and this was compared with the original ECOHIS. Minor changes were made to the Malay-ECOHIS before it was finalised. The Malay-ECOHIS' psychometric properties were assessed in terms of construct, convergent and discriminant validity as well as internal and test-retest reliability based on two separate studies involving 127 parents of 4-6 year old preschool children followed by oral examinations of 860 preschool children from 25 kindergartens from two districts in Selangor state, Malaysia. Non-parametric statistics were used to assess the relationships between the Malay-ECOHIS and the subjective and clinical outcome measures.

RESULTS

The Cronbach's alpha was 0.83 and the weighted Kappa was 0.95 (intraclass correlation = 0.94). The Malay-ECOHIS demonstrated significant associations with different subjective and normative measures, i.e. levels of oral health satisfaction, perceived oral health status, perceived oral health need, toothache experience, pattern of dental attendance, and caries status of preschool children. These significant associations supported its construct, convergent and discriminant validity as well as internal and test-retest reliability.

CONCLUSION

This study showed that the Malay-ECOHIS is a valid and reliable instrument to assess the negative impacts of oral disorders/conditions on the quality of life of 4-6 year old preschool children and their families in Malaysia.

Enamel fracture in the primary dentition has no impact on children's quality of life: implications for clinicians and researchers

AIM

The aim of this study was to quantify the impact of traumatic dental injuries (TDI) on oral-health-related quality of life (OHRQoL) of preschool children, when enamel fractures were either included or excluded within the category of TDI.

MATERIAL AND METHODS

An oral health survey was undertaken of preschool children, age 1-5 years attending public nurseries in Canoas, Brazil. Children were examined for TDI, dental caries, and malocclusion. Parents were interviewed on their perception of their child's OHRQoL (Early Childhood Oral Health Impact Scale-ECOHIS) and their sociodemographic background. Multivariable Poisson regression models with robust variance were fitted to assess the impacts of TDI (including and excluding enamel fractures) on OHRQoL.

RESULTS

A full dataset was collected from 76% of the eligible population. The prevalence of TDI was 13.4% (171/1275). The prevalence of any impact (ECOHIS ≥ 1) was significantly higher in children with crown discoloration (29.7%), enamel/dentin fracture (29.2%), and avulsion (73.3%), compared to children with enamel fracture (16.2%) or without a TDI (15.8%) (P < 0.001). Enamel fractures were the most prevalent TDI (40%) but halved the proportion of children with a reported impact from their TDI. The mean increase in OHRQoL impact for those children with a TDI was 1.59 (95%CI 1.20-2.10) when enamel fracture was included, and 1.86 (95%CI 1.39-2.50) when it was excluded.

CONCLUSION

Enamel fractures have no significant impact on young children's quality of life. Including enamel fractures within the diagnosis of TDI increases the prevalence of TDI while reducing the OHRQoL impact of TDI for the primary dentition.

The Role of School Social Environment on Dental Caries Experience in 8- to 12-Year-Old Brazilian Children: A Multilevel Analysis

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.

The Association between Participation of Adolescents in Community Groups and Dental Caries in a Deprived Area in Brazil

There is limited evidence concerning the role of social networks on the oral health of adolescents. This study assessed the association between the participation of adolescents in community groups and dental caries. A cross-sectional household-based study was carried out involving 200 subjects aged 15-19 years living in a deprived area in the state of Amazon, Brazil. Dental caries was assessed through dental examinations using the DMFT index conducted by a single examiner who was previously calibrated. Four dental caries outcomes were investigated, including caries experience (DMFT score), current caries (number of current decayed teeth), missing teeth due to caries, and the care index (ratio between number of filled teeth and DMFT score). Details of participation of adolescents in community groups, demographic and socioeconomic data and information on dental visiting were obtained through individual interviews. All caries measures were significantly higher in adolescents who did not participate in community groups compared to their counterparts. Multivariate Poisson regression showed that participation of adolescents in community groups was independently associated with all dental caries outcomes. After adjusting for confounders, participation in community groups was statistically associated with lower DMFT score (ratio of mean, RM: 0.33, 95% CI: 0.24-0.46), fewer decayed teeth (RM: 0.23, 95% CI: 0.11-0.47), fewer missing teeth (RM: 0.28, 95% CI: 0.17-0.47), and higher care index (RM: 1.69, 95% CI: 1.24-2.29) than those who did not participate. Participation of adolescents in community activities was related to lower levels of dental caries.

Oral Health-Related Quality of Life and Traumatic Dental Injuries in Young Permanent Incisors in Brazilian Schoolchildren: A Multilevel Approach

BACKGROUND

Traumatic dental injury (TDI) during childhood may negatively impact the quality of life of children.

OBJECTIVE

To describe the association of oral health-related quality of life (OHRQoL) and domains (oral symptons, functional limitation, emotional- and social-well-being) of children with individual and contextual variables.

METHODS

A cross-sectional study was performed using a representative sample of 1,201 schoolchildren, 8-10 years-old, from public and private schools of Belo Horizonte, Brazil. The CPQ8-10 was used to assess OHRQoL, dichotomized in low and high impact. Sociodemographic information was collected through questionnaires to parents. Children were examined at schools, using the Andreasen criteria. Individual variables were gender, age, number of residents in home, parents/caregivers' level of education, family income, and TDI (dichotomized into without trauma/mild trauma and severe trauma). Dental caries and malocclusion were considered co-variables. Contextual variables were the Social Vulnerability Index and type of school. Ethical approval and consent forms were obtained. Data were analyzed using SPSS for Windows 19.0 and HLM 6.06, including frequency distribution, chi-squared test and multilevel approach (p < 0.05).

RESULTS

The prevalence of a negative impact on OHRQoL in children with severe trauma was 55.9%. The TDI negatively impacted emotional and social domains of OHRQoL. A multilevel analysis revealed a significant difference in OHRQoL according to the type of school and showed that 16% of the total variance was due to contextual characteristics (p < 0.001; ICC = 0.16). The negative impact on OHRQoL was higher in girls (p = 0.009), younger children (p = 0.023), with severe TDI (p = 0.014), those from public schools (p = 0.017) and whose parents had a lower education level (p = 0.001).

CONCLUSION

Severe trauma impacts OHRQoL on emotional and social domains. Contextual dimensions add information to individual variability to explain higher impact, emphasizing socioeconomic inequalities.
