A comparative evaluation of micro leakage of a resin sealant after conventional acid-etch technique, two component self-etch and one-component total-etch adhesives- an in vitro study
Aims: To compare the micro leakage following conventional acid etching technique, total etch adhesives and self etching adhesives. Materials and Method: In this in vitro study was conducted on, thirty extracted first maxillary permanent premolars. The teeth were randomly technique into three groups of 10 each. Group I (Control): phosphoric acid 37%. Group II : phosphoric acid 37% + two layers total-etch adhesive Group III: self–etch adhesive. Then teeth were sealed by light-curing sealant. After thermocycling (500 cycle between 5-55°c), the samples were immersed in 1% buffered methylene blue solution for 24hrs and sectioned longitudinally in bucco-lingual directions. The sections were evaluated for dye penetration using stereomicroscope 40X. Kruskall-wallis test was used for comparison of micro-leakage among groups with P <0.05 as the limit of significance. Results: The results showed that Group III and Group I had same degree of micro-leakage and there was a significant difference in micro-leakage between these two groups with the Group I. (P<0.05). Conclusion: In conclusion, the single bond adhesive shows significantly less micro-leakage.
