Comparative evaluation of microleakage around Yuseal and Fissurit F Pit and Fissure Sealants in permanent teeth: An in-vitro study

Background: Deep pits and fissures may cause food retention and lead to caries. For prevention of this, the fissures are sealed using sealants. For successful outcome, the ability of sealants to seal margins is important. The purpose of this in vitro study, is to compare microleakage of YuSeal and Fissurit F sealants. Aim and Objectives: To compare the microleakage around Yuseal and Fissurit F sealants in permanent teeth. 1) To assess degree of microleakage around Yuseal used as sealant. 2) To assess degree of microleakage around Fissurit F used as sealant. 3) To compare microleakage around Yuseal and Fissurit F used as sealant. Materials & Methods: 30 selected teeth were designated to groups A and B, with each group consisting of 15 samples. Nail lacquer was coated on all the surfaces except occlusal surface and teeth were inserted in acrylic. 37% phosphoric acid was applied on both the groups. Fissurit F and Yuseal was applied to the teeth in (group A) and (group B), respectively. For 24 hours, the teeth were kept in 1 % methylene blue dye at 37°C. Through the sealed fissures, the teeth were sectioned buccolingually.&nbsp
