Analysis of adhesive techniques in dental sealants: an experimental study on premolars
Objetive: To identify which of the adhesive techniques presents greater microleakage. Methodology: In vitro experimental study, in which 60 premolars divided randomly into 4 groups were used. Group 1 (CT): conventional technique, conditioning with 37% orthophosphoric acid and sealant, Group 2 (GAA):...

| Sumario: | Objetive: To identify which of the adhesive techniques presents greater microleakage. Methodology: In vitro experimental study, in which 60 premolars divided randomly into 4 groups were used. Group 1 (CT): conventional technique, conditioning with 37% orthophosphoric acid and sealant, Group 2 (GAA): acid conditioning, application of etching and rinsing adhesive and sealant, Group 3 (GAS): application of universal adhesive and sealant, Group 4 (GAAS): acid conditioning, application of universal adhesive and sealant. All samples were thermocycled at 10,000 cycles, and then they were immersed for 24 hours in a 0.5% methylene blue solution and were sectioned buccolingually to evaluate microleakage in a stereomicroscope. The data were evaluated in the statistical software Minitab 19 with a confidence level of 95%. An ANOVA analysis was applied with a Tukey post-hoc (α=0.05). Results: the GAS group was the one that presented the highest degree of microleakage (mean=1,667), compared to the GAA group that had the lowest degree of microleakage (mean=1,000). However, there were no statistical differences between the GAS, TC, and GAAS adhesive technique groups, nor between the TC, GAAS, and GAA groups. Conclusions: The use of a resinous sealant with universal adhesive without previous acid etching was the one that presented the greatest microleakage. |
