Abstract
The goal of this study is to examine and appraise pit and fissure sealants' marginal sealing efficacy . Fifty healthy premolars were selected which was extracted atraumatically for orthodontic treatment and out of which 25 for Group I ( Conseal F )and 25 for Group II ( Embrace Wet Bond). The pit and fissure sealants were applied to the concerned groups, stored in artificial saliva, thermocycled and placed in 1% methylene blue solution . The teeth were rinsed, divided buccolingually and viewed for microleakage with optical stereomicroscope based on the penetration of dye, using Williams B and Winter GB criteria. At 95% confidence level statistical analysis was performed with Mann -Whitney test and chi square test .On comparing the microleakage scores a statistically significance was found (p< 0.001) .Group I (Conseal F ) showed a better marginal sealing efficiency than Group II (Embrace Wet Bond).
