Dental caries and externalizing behaviour problems in a high-risk child population

Bullying and oral health in Egyptian adolescents: the moderating role of sense of coherence and resistance to peer influence

BACKGROUND

Bullying is the intentional, repeated and prolonged aggressive behavior towards victim(s) who feel powerless to defend themselves. It could influence adolescents' mental health. Some adolescents possess coping skills which enable them to overcome such adversities. The present study assessed the association between bullying, sense of coherence (SOC), resistance to peer influence (RPI) and oral health in Egyptian adolescents.

MATERIALS AND METHODS

A cross-sectional survey that included 12-16 year old adolescents attending 6 schools in Damanhour, Egypt was conducted from March to December 2023. Data were collected through clinical examination and self-administered questionnaires. Clinical examination assessed dental caries (DMFT), oral hygiene (plaque index) and gingival condition (gingival index). Toothbrushing frequency and sugar consumption were assessed by (World Health Organization-child form), bullying (Revised Olweus Bully Victim Questionnaire), SOC (Sense of Coherence Scale-Short Form) and RPI (Resistance to Peer Influence Questionnaire). The independent variables were bullying, SOC and RPI. The dependent variables were untreated caries, gingival inflammation and toothbrushing frequency. Multivariable multilevel regression assessed the relationship between the independent and dependent variables after adjusting for potential confounders. Adjusted regression coefficients (B), adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated. Effect modifications by SOC and RPI were evaluated.

RESULTS

The response rate was 95.25% (N = 602), mean (SD) age was 14.01 (1.15). Half of the students (49.83%) were girls. About 42% had untreated caries, only 15.78% brushed their teeth twice daily and the mean (SD) gingival index was 1.57 (0.40). About 25% were victims, (9.30%) bullies and (18.60%) bully-victims. Victims showed significantly lower odds of twice daily toothbrushing (AOR = 0.52, p = 0.04). Bullies and bully-victims showed non-significantly higher odds of untreated caries (AOR = 1.42, p = 0.25), (AOR = 1.21, p = 0.42), respectively. Bullying was not associated with gingival inflammation. Higher SOC and RPI mitigated the impact of bullying on untreated caries and toothbrushing frequency.

CONCLUSION

Bullying was associated with higher odds of untreated caries and lower odds of twice daily toothbrushing in Egyptian adolescents. Higher SOC and RPI alleviated this relationship, highlighting the importance of individual coping strategies to oral health.

Family functioning and preschool children's oral health-related quality of life

INTRODUCTION

Identifying which aspects of how a family functions are relevant to child oral health provides opportunities for interventions targeting the family context. The aim of this study was to investigate the associations of general and domain-specific family functioning with oral health-related quality of life (OHRQoL) of 3-4-year-old children.

METHODS

Cross-sectional data from 740 parent-child dyads from East London were analysed. Family functioning was assessed with the 60-item Family Assessment Device that yields scores for general functioning and six domains (roles, behaviour control, communication, affective involvement, affective responsiveness and problem solving). Children's OHRQoL was measured using the Early Childhood Oral Health Impact Scale (ECOHIS), which measures the lifetime impacts of children's oral conditions on the child (child impact section, CIS) and family (family impact section, FIS). The associations of family functioning with the ECOHIS total, CIS and FIS scores were assessed in negative binomial regression models (rate ratios [RR] and 95% confidence intervals [95% CI] were calculated), adjusting for parental sociodemographic factors and child demographic factors and caries experience.

RESULTS

Children in families with unhealthy general functioning had 1.45 (95% CI: 0.87-2.43), 1.24 (95% CI: 0.73-2.13) and 2.19 (95% CI: 1.20-3.99) times greater ECOHIS total, CIS and FIS scores, respectively, than those in families with healthy general functioning after adjustment for confounders. Unhealthy functioning in the roles domain was associated with greater ECOHIS total and FIS scores. Unhealthy functioning in the problem solving, roles and affective involvement domains were also associated with greater FIS scores.

CONCLUSIONS

Unhealthy family functioning was associated with worse child OHRQoL, especially in terms of disrupting family life. Effective assignment and undertaking of roles should be further explored as a target for intervention.

Family functioning and dental caries among preschool children

OBJECTIVES

To investigate the relationship of family functioning with dental caries among 3-4-year-olds and the role of family functioning in explaining the relationship of family socioeconomic status (SES) with childhood dental caries.

METHODS

Data from 761 parent-child dyads who took part in the East London Oral Health Inequalities study were analyzed. Family functioning was assessed using the 60-item family assessment device that yielded scores on general functioning and six domains (roles, communication, problem-solving, affective involvement, affective responsiveness, and behavior control). Children were clinically examined at home for dental caries. The association of family functioning and family SES (education and socioeconomic classification) with dental caries (dmft and dt scores) was tested using negative binominal regression while adjusting for child and parental demographic factors.

RESULTS

Children from families with unhealthy general functioning had 1.49 (95% CI: 1.01-2.20) and 1.84 (95% CI: 1.20-2.82) times greater dmft and dt, respectively, than those from families with healthy functioning after adjustment for confounders. The estimates for the associations of parental education and socioeconomic classification with dmft and dt were attenuated by around 12%-18% after adjusting for family functioning. Of the six family functioning domains assessed, only unhealthy behavior control in the family was associated with greater numbers of decayed teeth after adjustments.

CONCLUSIONS

This study showed that unhealthy family functioning was associated with dental caries among young children. Family functioning partly explained the relationship between family SES and childhood dental caries.

Acquisition and establishment of the oral microbiota

Acquisition and establishment of the oral microbiota occur in a dynamic process over various stages and involve close and continuous interactions with the host and its environment. In the present review, we discuss the stages of this process in chronological order. We start with the prenatal period and address the following questions: ‘Is the fetus exposed to maternal microbiota during pregnancy?’ and ‘If so, what is the potential role of this exposure?’ We comment on recent reports of finding bacterial DNA in placenta during pregnancies, and provide current views on the potential functions of prenatal microbial encounters. Next, we discuss the physiological adaptations that take place in the newborn during the birth process and the effect of this phase of life on the acquisition of the oral microbiota. Is it really just exposure to maternal vaginal microbes that results in the difference between vaginally and Cesarian section‐born infants? Then, we review the postnatal phase, in which we focus on transmission of microbes, the intraoral niche specificity, the effects of the host behavior and environment, as well as the role of genetic background of the host on shaping the oral microbial ecosystem. We discuss the changes in oral microbiota during the transition from deciduous to permanent dentition and during puberty. We also address the finite knowledge on colonization of the oral cavity by microbes other than the bacterial component. Finally, we identify the main outstanding questions that limit our understanding of the acquisition and establishment of a healthy microbiome at an individual level.

Tooth-Level Analysis of Dental Caries in Primary Dentition in Myanmar Children

In developing countries, the prevalence of dental caries in children remains high, which means that implementing a simple and convenient classification is critical. The classification needs to be evidence-based and needs to reflect tooth-level information. In this study, the prevalence of dental caries in the primary dentition of 352 Myanmar school children at the ages of 5, 6, and 7 was analyzed at the tooth level to clarify the underlying data structure of the patterns of dental caries in the population. Ninety-three percent of subjects had caries in primary dentition and the mean number of decayed teeth in primary dentition was 7.54 ± 4.82. Based on the item response theory analysis, mixed-effect modeling, and Bayesian network analysis, we proposed the following classification: Group 1: No dental caries; Group 2: Dental caries in molar teeth or dental caries in maxillary anterior teeth; Group 3: Dental caries in both molar and maxillary anterior teeth; Group 4: Dental carries in mandibular anterior teeth. Dental caries (dmft) in the groups was different between groups. The results of characteristics of tooth-level information and classification presented in this study may be a useful instrument for the analysis of the data of dental caries prevalence in primary dentition.

Dental caries and externalizing behaviour problems in a high-risk child population

The aim of this study was to assess the association between externalizing behaviour problems and dental caries in children. A further objective was to explore direct and indirect pathways between sociodemographic factors, family functioning and parenting factors, oral health behaviours, externalizing behaviour problems, and dental caries using structural equation modelling. Cross-sectional data were collected on 251, 5- to 8-yr-old children from a paediatric dental practice in the Netherlands. Children's decayed, missing, and filled primary teeth (dmft) scores were obtained from their dental records. Validated self-report questionnaires were used to collect sociodemographic, behavioural, and family-related data. Externalizing problem behaviour was significantly associated with a higher dmft score [incidence risk ratio (IRR) = 1.19; 95% CI: 1.06-1.34], but this association did not remain significant after adjustment for sociodemographic factors (IRR = 1.11; 95% CI: 0.99-1.26). A valid path model was presented after applying some modifications. Findings from the model suggest that it is plausible that child behaviour problems are directly associated with dental caries via toothbrushing behaviour. The model also provided support that maternal education level, the restrictiveness and warmth of parenting, and the communication of the family, play an indirect role in the association between children's externalizing behavioural problems and dental caries experience.
