Abstract

Aim: The aim of this observational split-mouth study was to compare the retention and caries protective effect of four different sealant materials in children aged 6-13 years during a 2-year follow-up period.

Design: Eighty children were included in this study, which was conducted in Blato (Korčula island), Croatia. Each participant received at least two different sealant materials on caries-free permanent molars in two different quadrants. Sealant materials (M1 - glass-ionomer cement; M2, M4 - resin-based filled sealants; M3 - resin-based unfilled sealant) were delivered in a random order.

Results: The results of this study showed that M2 (30 teeth, 46.2%) and M4 (27 teeth, 46.6%) showed statistically significantly higher number of teeth with total retention after 2-year follow-up period, in comparison with M1 (10 teeth, 19.2%) or M3 (12 teeth, 20.7%) (p < .001). There was no statistically significant difference in caries occurrence between different groups in which the sealant material was totally retained.

Conclusions: According to the results of this study, filled resin-based sealant materials showed better retention during the 2-year follow-up period while both resin-based and glass-ionomer sealants demonstrated protection against dental caries if totally retained on the occlusal surface.

Keywords: caries prevention; glass-ionomer sealant; resin-based sealant; sealant retention.
