Microleakage of a Self-adhesive Flowable Composite, a Self-adhesive Fissure Sealant and a Conventional Fissure sealant in Permanent Teeth with/without Saliva Contamination
Objectives: Application of fissure sealants is a practical method for prevention of occlusal pit and fissure caries. Microleakage is an important factor affecting the success of fissure sealant treatment. This study aimed to assess the microleakage of a self-adhesive flowable composite, a self-adhesive fissure sealant and a conventional fissure sealant in permanent teeth with/without saliva contamination.
Materials and Methods: This in vitro, experimental study evaluated 108 extracted human third molars, which were randomly divided into six groups (n=18) of control, Denu fissure sealant applied on etched enamel with/without saliva contamination, Vertise Flow self-adhesive composite applied on rinsed and dried enamel with/without saliva contamination and self-adhesive fissure sealant applied on rinsed and dried enamel with/without saliva contamination. Microleakage was assessed with the dye penetration technique using the silver nitrate solution. Data were analyzed using the Kruskal-Wallis test and Dunn test.
Results: Microleakage of the conventional fissure sealant with/without saliva contamination was significantly lower than that in other groups (P<0.05).
Conclusion: Microleakage of conventional fissure sealant is less than that of self-adhesive fissure sealant and self-adhesive composite, irrespective of saliva contamination.
