Abstract

Background:  The purpose of this study was to investigate and compare the microleakage of three different pit and fissure sealants. Materials & Method: Total 150 therapeutically extracted premolars with absence of any carious lesion and anomalies were taken and equally divided into three different groups with fifty samples (50) in each group. Group A: Conventional pit and fissure sealant (Helioseal –F), Group B: Glass ionomer cement (Fuji VII) based pit and fissure sealant . Group C: Flowable nanocomposite (Filtek Z-350XT). Samples were cleaned with slurry of pumice and etched with phosphoric acid etchant. After thorough washing and drying, teeth were treated and cured with the respective sealants, followed by thermocycling and immersion in 2% methylene blue dye for fourty eight hours. Teeth were then sectioned buccolingually and examined under stereomicroscope. The data was further subjected to statistical analysis. Results: Group A showed the least microleakage followed by Group C and Group B. Conclusion: Microleakage was seen in all the groups. Maximum microleakage was observed in group B (Fuji VII) followed by group C (Flowable nanocomposite, Filtek Z-350XT) and least was in group A ( Conventional pit and fissure sealant, Helioseal –F ).

Keywords: Pit and fissure sealants, Microleakage.
