An Online Cross-Sectional Survey on Oral Healthcare Among School-Age Children During COVID-19 Epidemic in Wuhan, China

Impact of the COVID-19 lockdown on the oral health status of paediatric dental patients in Greece

BACKGROUND

Limited evidence regarding the post-COVID-19 dental status of paediatric patients is available, with most studies assessing only children's oral health habits.

AIM

To evaluate the effect of the COVID-19 lockdown on the oral health of paediatric dental patients in Greece.

DESIGN

This was a retrospective cohort study that included a questionnaire on children's oral health behavior and a clinical examination assessing dental caries and dental treatment needs using the International Caries Detection and Assessment System criteria, dmft/DMFT, and Treatment Need Index. The Wilcoxon signed-rank test was used for a statistical comparison between questionnaire and clinical data before, during, and after the lockdown.

RESULTS

A total of 102 children with a median age of 9 years were recruited from the current cohort of patients that had their last dental examination 6 months prior to the lockdown. Results from the questionnaire showed decreased brushing frequency with increased eating frequency and sugar consumption during the lockdown period (p < .001). Moreover, 16.5% had to visit the dentist for urgent care during the lockdown, 13.6% experienced dental pain, and 51.5% did not experience any dental emergencies. Clinical examination, after the lockdown, recorded significantly increased mean dmft/DMFT scores by 0.63 units in the primary dentition (p = .01) and 0.52 units in the permanent teeth (p = .002). Significantly higher treatment needs, with more carious lesions requiring extensive treatment after the lockdown, were recorded (p < .001).

CONCLUSION

The COVID-19 lockdown negatively affected children's oral health behavior: caries prevalence increased and more complex dental treatments were required.

COVID-19 Lockdown: Impact on Oral Health-Related Behaviors and Practices of Portuguese and Spanish Children

This study aimed to assess and compare the impact of COVID-19 pandemic lockdowns on the oral health attitudes, dietary habits and access to dental care of Portuguese and Spanish children. A cross-sectional observational study involving caregivers of 3−17-year-old children who had cohabited during a COVID-19 pandemic lockdown in Spain and Portugal was conducted. Caregivers completed an online anonymous questionnaire. Aiming groups comparison, chi-square test was used for qualitative variables. 770 surveys were obtained. Significant changes in the children’s routine were higher in Portugal (p < 0.001). Both countries showed a large percentage of children who had between 2−3 snacks between meals (p < 0.001) and a higher consumption of snacks was particularly noticed among Spanish children with untreated dental caries during the lockdown (p = 0.003). Most caregivers reported children’s oral hygiene habits did not suffer noteworthy alterations (p = 0.417), although parental supervision of toothbrushing was associated with dental attendance during the lockdown. The majority of the sample had no dental attendance during confinement. Confinement appears to have not markedly affected the oral health status and habits of the majority of these children, although an important impact of some demographic and behavioral factors upon dietary and oral care/habits was detected.

The Knowledge and Attitude of Parents About the Dental Treatment of Their Children During the New Type of Coronavirus Outbreak in Northern Cyprus

Background

The aim of this study was to assess the knowledge and attitude of parents living in Northern Cyprus about the oral care and dental treatments of their children during the outbreak of the new type of Coronavirus (COVID-19).

Methods

An online self-administered questionnaire was conducted consisting of 33 questions. A total of 256 parents participated in this study. The questionnaire was divided into two parts. The first part consists of demographic information and the second part consists of the awareness and knowledge of parents about dental treatments during COVID-19. SPSS software was used for statistical data analysis.

Results

In total, 81.9% of the mothers and 59.6% of the fathers stated that their children could be infected with COVID-19 during dental treatments and were apprehensive about their children undergoing such treatment because of the outbreak. Participants were asked about their knowledge regarding the transmission of COVID-19 through air droplets during dental treatments and the findings revealed that mothers (89.5%) were more aware of this than fathers (77.2%). The majority of the participants (77%) stated that their children could become infected with COVID-19 during dental treatments and were apprehensive about their children undergoing such treatment because of the outbreak; however, 65.1% did not take any extra precautions regarding their children's oral health and care.

Conclusion

The majority of the parents in Northern Cyprus have good knowledge about dental clinics being one of the high-risk areas where COVID-19 can be transmitted by aerosols from infected people. However, further steps need to be taken to strengthen parents' motivations for home oral care and more studies are needed to assess the continuing impact of the COVID-19 pandemic on parents' attitudes toward and knowledge about dental procedures.
