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-seal conventional fissure sealant applied on etched enamel with/without saliva contamination, vertise flow self-adhesive flowable composite applied on rinsed and dried enamel with/without saliva contamination and prevent seal self-adhesive fissure sealant applied on rinsed and dried enamel with/without saliva contamination. microleakage was assessed using the dye penetration technique and subsequent observation of samples under a stereomicroscope. data were analyzed using the kruskal-wallis and tukey’s test. results: microleakage of the conventional fissure sealant with/without saliva contamination was significantly lower than that of other groups (p<0.05). conclusion: microleakage of the conventional fissure sealant is less than that of self-adhesive fissure sealant and self-adhesive composite, irrespective of saliva contamination.
