CARIES
High satisfaction and safety regarding SS-suction were reported among dental nurses even though the service is provided without dental assistants. Caries as reported outcomes of children sealed with SS-suction were comparable to those of children sealed with the usual standard procedure, i.e., high-power suction by dental assistants.Satisfaction with SS-suction was very high in all dimensions and helped dental nurses to provide dental services without dental assistance, which was consistent with the previous efficacy study [To evaluate the quality of moisture control, short-term retention is a good indicator. However, the COVID-19 pandemic during the research led to lifestyle changes in Thailand. The government declared a state of emergency and ordered the closure of educational institutions throughout the country. The evaluation period was delayed to 15–18 months and showed low complete retention of 31–32% on the occlusal and 17–18% on buccal surfaces [In this study, the interesting factor investigated was moisture control, and the controlled factors were age, tooth position, follow up time, dietary and toothbrushing behavior, and fluoride exposure. The oral health prevention and promotion program has been implemented in schools in Thailand for more than 30 years, but it was temporarily interrupted during the COVID-19 pandemic [The strength of the study lies in the study design, and the ITT and sensitivity analysis were performed to confirm the result. A limitation of the study is the follow-up time, and the interim results were not assessed. Suggestions for further studies are to improve the design of the SS vacuums, especially their size, to consider the appropriate combination of toothbrushes and dental sealants, and conduct an economic evaluation of the innovation. Due to the property of aerosol reduction [
