Retention and anti-cariogenic effect of sealants in primary molars. Controlled trial

Abstract

Objective: Evaluate retention and anti-cariogenic effect of sealants in primary molars. Material and Methods: A controlled, single -blind, split-mouth design, 320 seconds primary molars caries free of 80 healthy children aged 3 and 5 years clinical trial was conducted. They were sealed with glass ionomer Ketac Molar® 3M second molars rights and resin sealant 3M® Clinpro left second molar. After twelve months the retention and caries incidence was evaluated. Data were processed with SPSS V-19 program. The Chi square test and Fisher test was used. Results: The control group scored 20% overall retention and experimental 13.3%. The Clinpro® sealant showed 28.6% loss, and sealer Ketac Molar® 32%. Within the experimental molar presents no lesions, whereas the control group there was a 16.3% incidence of caries, these differences were statistically significant (p<0.05). Conclusion: The resin sealant retention was higher than the glass ionomer cement after 1 year. Retention of sealants on the mandibular teeth was higher than that of the maxillary teeth. There was no incidence of dental caries lesions in the group of molars sealed with glass ionomer loss, contrary to the group receiving resin-based sealant which 7 cases of the disease were presented.
