A Cluster Randomized Controlled Trial of the Dental Sealants Quality in Rural Schoolchildren Using Innovative Suction without Dental Assistance.

This study examined whether the moisture control innovation (tongue and cheek retractors and saliva contamination (SS-suction)) used without dental assistance could improve the quality of dental sealant in rural Thai school children compared to a standard treatment, i.e., high power suction with dental assistance. A single blind, cluster randomized controlled trial was conducted. Participants were 15 dental nurses working in sub-district health promoting hospitals and 482 children. All dental nurses attended workshops of SS-suction and revised dental sealant procedures. Children with sound lower first permanent molar teeth were simple-randomly assigned to either an intervention or control group. The children in the intervention group were sealed with SS-suction, and the children in the control group were sealed with high power suction and dental assistance. There were 244 children in the intervention group and 238 children in the control group. Dental nurses' satisfaction on SS-suction was record by visual analogue scale (VAS) for each tooth during treatment. After 15-18 months, caries on sealed surfaces were examined. The results showed that the median satisfaction score of SS-suction was 9 out of 10, and 17-18% children experienced uncomfortable sensation during insertion or removal. The uncomfortable feeling disappeared once the suction was in place. Caries on sealed surfaces did not differ significantly between the intervention and control groups. Caries on the occlusal surface was present in 26.7% and 27.5%, and caries on the buccal surface was present in 35.2% and 36.4% of cases in the intervention and control groups, respectively. In conclusion, dental nurses were satisfied with SS-suction in terms of both function and safety. The effectiveness of SS-suction was compatible with the standard procedure after 15-18 months.

Cariogenic snack consumption among Southern Thai preschool children and its international comparison during pandemic of COVID-19: A cross-sectional study

Aim: The aim of this study was to describe and analyze factors related to dietary habits among young children. This study is part of the practice guideline development to promote good oral health under the pandemic situation. Materials and Methods: A cross-sectional study was conducted among parents or relatives of 3–5 years old children who attended child care centers in one province of Southern Thailand using an online questionnaire submitted via teachers of each cluster. The number of participants required was 265 and cluster sampling method was performed. Logistic regression was used to identify the factors related to dietary habit. The questionnaire included general information, snack consumption, and factors related to snack consumption during the stay-at-home period. Results: Fifty-seven percent of the children did not increase their cariogenic snack consumption and most families increased their good food habits. Reservation of cariogenic snacks at home and high previous frequency of cariogenic snacks consumption were related to the increasing of cariogenic snack consumption when controlling for parents’ dietary control and good food behavior. Conclusion: Most of the children did not increase their snack consumption during the stay-at-home period and the factors related to increase of snake consumption behavior were reservation of snack and high baseline frequency of consumption.
