Assessment of Penetration Depth and Microleakage of Different Pit and Fissure Sealants Using Dye Penetration Method: An In Vitro Study

Evaluating the effect of three fissure preparation techniques on microleakage of a colored flowable composite used as a fissure sealant

“…In a study evaluating flowable composite, composite and fissure sealant materials applied to cover fissures, flowable composites were found to have the best performance in terms of penetration depth and microleakage avoidance [41]. In addition to the results obtained by Gillet et al [41] and Dixit et al [42] reported that the incidence of microleakage was lower in groups treated with flowable composite materials in conjunction with bonding agents compared to groups treated without bonding agents Two other studies provided further support for this technique, reporting that the use of pit and fissure sealants in conjunction with bonding agents increases the efficacy of the sealant [43,44]. It has also been demonstrated that the use of bonding agent substantially decreases the incidence of microleakage, even on a tooth surface contaminated with saliva [17,45].…”

“…Some studies in the literature examine enamel preparation techniques prior to the application of a fissure sealant, and they suggest that the increased surface area provides a thicker layer of filling, which in turn provides greater wear resistance [42,56]. Shapira et al [57] reported that enlarging and deepening the fissures by mechanical preparation increases the bonding strength.…”
