THE COMPARATIVE STUDY OF MICROLEAKAGE BETWEEN RESIN-BASED AND GIOMER PIT AND FISSURE SEALANTS: A PILOT STUDY

Abstract

This pilot study aimed to compare the mean percentage of microleakage between Giomer pit and fissure sealants and Resin-based pit and fissure sealants. 10 Maxillary premolars were randomly divided into 2 groups. Group 1 Resin-based pit and fissure sealants with 37% Phosphoric acid etching, Group 2 Giomer pit and fissure sealants with Self-etch primer. The specimens were then thermo-cycling from 5◦C to 55◦C for 5000 cycles using a dwell time of 30 s was carried out in a thermocycling unit for stimulated the usage in oral cavity. Then, immersed in 5% Methylene blue solution at 37 ºC for 24 hours. All samples were sectioned in Bucco-Lingual direction to provide 2 segments. The mean percentage of microleakage were analyzed under Stereomicroscope. The result showed microleakage in Giomer pit and fissure sealants was higher than Resin-based pit and fissure sealants but no statistic significant. (p = 0.151)
