Twelve-month clinical evaluation of retention of resin-based sealant on first permanent molars

Abstract

Introduction: The majority of researchers agree that sealants need to be monitored and kept in good condition because even a small amount of sealant loss raises the possibility of developing caries lesions. The first year after application is when sealant loss is reported to be at its highest. This motivated us to monitor silanized patients who received resin-based sealant for a full year. Aim: The aim of this study was to monitor the retention of resin-based sealant on fully erupted first permanent molars in children aged 7-8 years. Materials and methods: Prior to sealant application, all first permanent molars included in the study were subjected to visual diagnostics using the ICDAS II system and diagnostics with VistaCamiX Macro using the same system. Silanization was performed according to the indications. The follow-up checks were performed at 3, 6, and 12 months in accordance with the accepted methodology. Results: At the end of the first year, completely lost sealant was reported in approximately 8%-9% of the monitored surfaces using various diagnostic methods. Conclusions: Resin-based sealants are suitable for application on occlusal surfaces of teeth when it is possible to properly isolate the field of work. They provide both an excellent prophylactic effect of caries and very good retention.
