Abstract
Design A randomised controlled trial (RCT) conducted over a period of 3 years.
Intervention Either conventional glass-ionomer (Ketac-bond; 3M ESPE St. Paul, MN 55144-1000) or resin-modified glass-ionomer (Vitremer; 3M ESPE St. Paul, MN 55144-1000) sealants were applied to first permanent molars, and oral hygiene education was given. Clinical evaluations were carried out at 6, 12, 24, and 36 months after the application of the sealant.
Outcome measure Retention rates and occlusal caries incidence were monitored.
Results The difference in retention rates between the two materials was statistically significant. The experimental groups showed a caries incidence of 93, 78, 49, and 56% lower than the control group (P<0.01) for the four evaluation periods, respectively (see Table 1).
Conclusions The retention rates for glass-ionomer were low. Nevertheless, the statistically lower caries incidence in experimental groups compared with control group suggests a cariostatic effect.
