Sealant Versus Fluoride Varnish Regarding Patient-Centred Experience Among Preschool Children
Objectives: This randomised controlled trial aimed to compare the effectiveness of glass ionomer sealant (GIS) placement and sodium fluoride varnish (NaFV) application regarding patient-reported experience in terms of cooperativeness, dental anxiety and pain levels among preschool children in 18 months.
Methods: Healthy preschool children attending kindergarten grades 1 and 2 with at least one sound second primary molar were recruited. Eligible children were randomly allocated to receive either 5% NaFV application quarterly, or a single GIS placement with finger-press technique. Clinical parameters were assessed by one calibrated examiner, whereas sociodemographic and oral-health related factors were collected with a validated parental questionnaire. Oral hygiene, caries status, pre- and postoperative child behaviours and self-rated pain levels were recorded at baseline and at biannual follow-ups.
Results: A total of 228 and 185 children were allocated into NaFV and GIS group at baseline respectively, with 109 and 86 children being followed at 18 months. Significant reduction in preoperative dental anxiety over the 18 months was only found in GIS group (p=0.039); whereas significant improvement in postoperative behaviour was found in both NaFV (p=0.015) and GIS groups (p<0.001). Children in GIS group were significantly more anxious immediately after GIS placement (p=0.016), but markedly less anxious at 12 months (p=0.006). Intergroup comparisons of anxiety and cooperation levels did not show any significant difference at 6 and 18 months. Preoperative and postoperative cooperativeness at 6 and 12 months were significantly associated with the dental anxiety level at 18 months (p≤0.003), but not for other sociodemographic factors.
Conclusions: Cooperativeness and dental anxiety levels of the study children gradually improved with time. GIS placement induced more dental anxiety to preschool children postoperatively than NAFV application, but no difference in the cooperativeness of the two groups was found at 18 months. Past dental anxiety level predicted the behaviour of children at 18 months.
