Abstract
ObjectiveThe objective of this study is to investigate the beneficial effect of not rinsing for 30 min in arresting early childhood caries after SDF therapy. MethodsThis randomised clinical trial recruited 3- to 4-year-old kindergarten children with active (soft) dentine caries. A questionnaire was sent to the parents to collect children's demographic data and oral health-related behaviours. A dentist conducted an oral examination and measured the caries experience using dmft index and oral hygiene using visible plaque index. After 38 % SDF therapy, the children were randomly allocated into two groups. Children in group A were instructed to rinse with water immediately, whereas children in group B were asked to refrain from rinsing, drinking, or eating for 30 min. After six months, the same examiner determined the lesion activity (active/arrest) of the SDF-treated carious tooth surface. Generalized Estimating Equations was used to compare the proportion of caries arrest (caries-arrest rate) between the two groups. ResultsThis study recruited 298 children with 1,158 decayed tooth surfaces receiving SDF therapy at baseline and evaluated 275 (92 %) children with 1,069 (92 %) SDF-treated tooth-surface at the six-month examination. The demographic background, oral hygiene and caries status of two groups were comparable at baseline (p > 0.05). The caries-arrest rate for group A and group B were 65 % (337/519) and 61 % (338/550), respectively (p = 0.28). ConclusionThis randomised clinical trial found not rinsing for 30 min after SDF therapy is not better than immediate rinsing in arresting early childhood caries. Clinical significanceTopical SDF application leaves an unpleasant taste in the mouth, which may affect the acceptance or even rejection of SDF therapy among young children. This study provides clinicians with information to make their decision on postoperative instruction after SDF therapy.
