Aim: This study compared the micro leakage of light cure glass monomer and flow able compomer as pit and fissure sealant, with and without tooth preparation. Materials and Methods: One hundred premolar's that were extracted for orthodontic purpose were used. After adequate storage and surface debridement, the teeth were randomly divided into four groups. In Group I and III, the occlusal surfaces were left intact, while in Group II and Group IV, tooth surfaces were prepared. Teethin Group I and Group II were sealed with Light cure glass ionomer, whereas flowable compomer was used to seal teeth in Group III and IV. The sealed teeth were then immersed in dye. Subsequently, buccolingual sections were made and each section was examined under stereomicroscope for micro leakage followed by scoring. Results: In group I, micro leakage score ranged from 2 to 4 with mean of 3.64 (±0.757), while in group II the range was observed to be 1−4 with mean of 2.88 (±1.236). Group III recorded a range of 0−4 with the mean of 2.20 (±1.443) while 0−2 and 0.60 (±0.707) being the range and mean observed, respectively, for group IV. Conclusion: Flowable compomer placed after tooth preparation showed better penetration and less marginal leakage than the light cure glass ionomer. [ABSTRACT FROM AUTHOR] |
