Faculté de médecine dentaireEvaluation of micro leakage of pits and fissures sealants using different materials (unfilled resin vs GIC) and different procedures (Laser vs conventional) : an in vitro studyDescription:
Pit and fissure sealant is one of the most frequent preventive treatments in pediatric dentistry.(1,2,3) The objective of our study is to compare in vitro the micro leakage of sealant in 3 different conditions. First group: 15 teeth pretreated with laser and etching and obturated with “Fuji triage”. Second group: 15 teeth pretreated with laser and etching and obturated with non charged resin “Clinpro” and third group: 15 teeth pretreated with etching and obturated with non charged resin “Clinpro.
The aim of this study is to increase the chances of success of pit and fissure sealant by identifying the optimal condition.
The study is an in vitro randomized control trial accomplished on 45 freshly extracted intact premolars (stored in Thymol solution 2%).
The criteria of judgment is the depth of micro leakage, it is a quantitative criteria evaluated in micrometer after a bucco-lingual longitudinal slice cut using a light microscope times 20 magnification.
