Caries-preventive efficacy and retention of a resin-modified glass ionomer cement and a resin-based fissure sealant: a 3-year split-mouth randomised clinical trial.
PURPOSE This prospect i ve clinical trial compared the retention rate and caries-preventive efficacy of two types of sealant modalities over a 3-year period . MATERIAL S AND METHODS Using a split-mouth r and omised design , 1280 sealants were r and omly applied on sound permanent second molars of 320 young patients aged between 12 and 16 years . Half of the teeth ( n = 640 ) were sealed with a resin-modified glass ionomer cement ( RMGIC ) ( Vitremer ™ , 3 M ESPE ) and the other half ( n = 640 ) with a conventional light-cure , resin-based fissure sealant ( LCRB ) ( Fluoroshield ® , Dentsply Caulk ) . Teeth were evaluated at baseline , 6- , 12- , 18- , 24- , 30- and 36-month intervals with regard to retention and new caries development . RESULTS On the sealed occlusal surfaces after 3 years , 5.10 % of RMGIC and 91.08 % of LCRB sealants were totally intact and 6.37 % of RMGIC and 7.65 % of LCRB sealants were partially intact . New caries lesions were found in 20.06 % of RMGIC sealed occlusal surfaces , compared to 8.91 % for LCRB sealants . CONCLUSIONS The findings of the present clinical study suggest that RMGIC should be used only as a transitional sealant that can be applied to newly erupting teeth throughout the eruptive process , whereas LCRB sealants are used to successfully prevent occlusal caries lesions once an effective rubber dam can be achieved . It can be concluded that there are differences between the RMGIC and LCRB sealants over a 3-year period in terms of the retention rate and caries-preventive efficacy . RMGIC can serve as a simple and economic sealing solution , however provisional . Due to its poor retention rate , periodic recalls are necessary , even after 6 months , to eventually replace the lost sealant
