Impact of the COVID-19 lockdown on the oral health behaviour of young children.

AIM: Children up to the age of 10 are dependant primarily on their caregivers for oral care; COVID-19 lockdowns may have disrupted this care. We therefore assessed whether the COVID-19 lockdown affected routine parental oral care for their children. METHODS: A short online survey regarding oral health behaviour and changes in the home setting during the COVID-19 lockdown was emailed to parents (n = 782, response 15%) participating in an existing study 'Healthy Teeth All Aboard (HTAA)'. RESULTS: During the lockdown, 29% of parents reported that they skipped their children's toothbrushing more often than before the lockdown, and 49% of the children were allowed to consume sugary snacks or drinks more often. These behaviours were not significantly associated with socio-economic status, country of birth of the mother, work situation of the parents, school attendance patterns or HTAA participation status. CONCLUSION: The COVID-19 lockdown affected the daily oral hygiene routines of children, potentially increasing caries risk. CLINICAL RELEVANCE: Dental professionals should be aware of the potential impacts on oral health in children in the circumstance of a new lockdown. Parents should be made aware of the oral health consequences of a lockdown.

Long-term effects of a community-based oral health intervention for young children in the Netherlands: A 5-year follow-up.

OBJECTIVES: The aim of this study was to assess whether referral of parents of 6 months old children by a well-child care (WCC) clinic medical practitioner for an early first dental visit combined with the Non Operative Caries Treatment and Prevention (NOCTP) approach in dental practices was effective to maintain oral health in children. METHODS: The study was conducted as a quasi-experimental comparative pre-post trial with a baseline measurement before the intervention. In total 1347 children were allocated at the age of 6 months and 306 children (intervention group: n = 166; care as usual (CAU) group: n = 140) underwent an oral examination at 5 years of age and their parents completed a questionnaire. Nonparametric tests and Hurdle models were used to determine differences in caries experience between the intervention and CAU groups. RESULTS: Children in the intervention group had significantly lower caries experience (d1,2,3 mfs) than children in the CAU group (Median = 2 vs. 5, r = .15, p < .01). Children in the intervention group had significantly fewer inactive caries lesions compared with children in the CAU group (Median = 2 vs. 3, r = .18, p < .001). No differences were found for dentin caries experience and also no differences for active caries lesions. CONCLUSIONS: Referral of parents of newborns for a preventive first dental visit by a WCC medical practitioner combined with NOCTP in dental practices may offer a new opportunity to reduce enamel caries lesions in young children.

Experiencing Financial Strain and Clinically Assessed Caries Experience in Dentate Adults Aged 25-44 Years: An Exploration of Potential Pathways.

Large socioeconomic inequalities still exist in oral health. It is already known that oral health-related behaviour may contribute to these inequalities, but why people with a lower socioeconomic position behave less healthily is not easily understood. A possible explanation that integrates insights on health behaviour, stress, and financial resources is the pathway of behavioural responses to financial strain. The aim of this study was to assess to what extent financial strain is associated with clinically assessed caries experience in a population-based study of dentate adults, independently of other socioeconomic indicators. Furthermore, the potential mediating pathways of oral health-related behaviours (oral hygiene, dietary habits, preventive dental visits) were explored. Dentate participants, aged 25-44 years, taking part in a survey on oral health and preventive behaviour in the Netherlands in 2013 were clinically examined on - among others - caries experience (DMFS index) and level of oral hygiene (OHI-s index). Financial strain, frequency of tooth brushing, dietary habits, attendance of (preventive) dental visits in the past year, and demographic variables were assessed via questionnaires. Negative binomial hurdle models were used to study the association between financial strain and DMFS and between oral health behavioural indicators and DMFS. Although it was observed that experiencing financial strain did not seem to affect whether there is any caries experience or not, among those having any caries (DMFS >0) suffering from financial strain was associated with a higher caries prevalence, independent of educational level and income. None of the studied potential mediators could explain this association.

The Relationship between Caries-Specific Quality of Life and Generic Wellbeing in a Dutch Pediatric Population.

Dental caries has significant negative impacts on the lives of children and young people. Whilst the impacts on children's oral health-related quality of life (OHRQoL) have been increasingly investigated, the effect on children's overall wellbeing remains largely unknown. Data were obtained from a survey conducted across four cities in the Netherlands. Children and their parents completed a series of questionnaires, which included Dutch versions of a caries-specific pediatric measure of OHRQoL (CARIES-QC-NL) and a generic pediatric health utility measure (CHU9D-NL). The participating children underwent dental examinations to determine their caries status. A total of 486 11-year-old children participated in the study, of which 184 had caries experience (38%). The mean number of decayed, missing and filled teeth (DMFT) was 0.71. The CARIES-QC-NL was found to have statistically significant correlations with the DMFT and CHU9D-NL. There were no statistically significant correlations between the CHU9D and the clinical variables. The CARIES-QC-NL had acceptable internal consistency and construct validity in this population despite the low prevalence of active caries. A relationship was demonstrated between OHRQoL and generic wellbeing in this population. Despite this, the CHU9D did not show any correlation with the clinical data, which may limit its application in studies of the impact of dental caries.

The Prevalence of Tooth Wear in the Dutch Adult Population.

This study aimed to assess the prevalence of tooth wear in different age groups of the Dutch adult population and to determine this tooth wear distribution by gender, socioeconomic class, and type of teeth. Results were compared with the outcomes of a previous study in a comparable population. As part of a comprehensive investigation of the oral health of the general Dutch adult population in 2013, tooth wear was assessed among 1,125 subjects in the city of 's-Hertogenbosch. The data collected were subjected to stratified analysis by 5 age groups (25-34, 35-44, 45-54, 55-64, and 65-74 years), gender, socioeconomic class, and type of teeth. Tooth wear was assessed using a 5-point ordinal occlusal/incisal grading scale. The number of teeth affected was higher in older age groups. Men showed more tooth wear than women, and subjects with low socioeconomic status (low SES) showed on average higher scores than those with high SES. Tooth wear prevalence found in this study was higher in all age groups than in the previous study. The present study found prevalences of 13% for mild tooth wear and 80% for moderate tooth wear, leading to the conclusion that these are common conditions in the Dutch adult population. Severe tooth wear (prevalence 6%) may however be characterized as rare. A tendency was found for there to be more tooth wear in older age groups, in men as compared with women, in persons with lower SES, and in the present survey as compared with the previous one.
