COMPARATIVE EVALUATION OF MICROLEAKAGE OF PIT AND FISSURE SEALANT USING CONVENTIONAL AND NOVEL ETCHANT

Abstract

INTRODUCTION: Pit and fissure caries accounts for 80% of total caries experience. Sealant has been described as a material introduced into the occlusal pits
and fissures of caries susceptible teeth, forming a micro mechanically bonded protective layer. MATERIALS AND METHODS: 4 molar teeth with caries or
anomalies, extracted for orthodontic purposes were taken. Samples were thoroughly cleaned by water and then were preserved in normal saline. The teeth were
cleaned, washed and dried prior to the sealant application. The teeth were then separated into two different groups. Group 1 and Group 2. RESULTS AND
DISCUSSION: The current study findings shows that the surfaces were pre etched with tricalcium phosphate and citric acid - group 1; calcium phosphate and
phosphoric acid- group 2. It shows that the two groups have zero microleakage. CONCLUSION: There is poor correlation between the extent of micro leakage
found in vitro & in vivo study. Further studies are required to evaluate clinical success and to prove these effects considering the potential effects.
