| dc.description | Background and objectives: Microleakage is the clinically undetectable passageway of oral fluids, microorganisms, molecules and other factors not only due to the misapplication of the sealant, but also to the enamel contamination in pits and fissures; as a result of this a possible carious lesion may occur. Research suggests that placing an adhesive system prior to the application of the sealant improves bond strength and improves marginal flow in pits and fissures. The objective of this in vitro study was to compare the degree of microleakage between a resinous sealant vs. a flowable resin with and without previous application of an adhesive system in pits and fissures. Materials and methods: Twelve wisdom teeth were extracted for therapeutic reasons and clinically inspected based on inclusion and exclusion criteria. They were grouped into 4 groups of 3 samples each: Group A1. resinous sealant with adhesive, Group A2. resinous sealant without adhesive, Group B1. flowable resin with adhesive, Group B2. flowable resin without adhesive. The samples were exposed to thermo-cycling and submerged in 2 percent methylene blue, to later be sectioned in order to observe the degree of microleakage with the help of a stereomicroscope. Data were interpreted using the Contingency Coefficient and Chisquare test. Results: In relation to the penetration of methylene blue and under the criteria of measurement of microleakage in pits and fissures, 83.3 percent of the total of the sample with previous placement of the adhesive, both in resinous sealant and flowable resin, presented zero penetration in the pits and fissures; while the group without previous placement of the adhesive presented only 33.3 percent of zero penetration. Conclusions: there was no statistically significant difference between the 4 groups; however, for greater reliability it was observed that 66.7 percent of the non-adhesive group had higher degrees of filtration than the adhesivegroup, starting from the limited penetration of the sealant to the total penetration of the methylene blue in the fissure. In conclusion, the use of a sealant with bonding agent is a reliable alternative to seal pits and fissures. | en |
