摘要

In order to ensure that there is no occurrence of recurrent caries, post-operative sensitivity and marginal staining, it is important that the material used for restorative purposes achieves good seal with the adjacent tooth structure and causes minimal microleakage. Numerous studies have been conducted to evaluate microleakage of different adhesive systems but none of the materials used, showed complete reduction in microleakage. As no adhesive systems were found to eliminate microleakage at dentin margins, use of a resinmodified glass ionomer as a base can be recommended.Aim: To evaluate microleakage of three different bonding agents and compared with resin modified glass ionomer at coronal and apical margins of class V restorations.Materials and Methods: For this in-vitro study done in February 2019, total sixty extracted human upper premolars were selected and randomly divided into four groups of 15 teeth each (30 cavity preparations). Class V cavity preparations were done on buccal and lingual surfaces with occlusal margins in enamel and gingival margins in cementum. In 3 experimental groups, cavities were treated with Adper Single-Bond 2, Adper SE Plus and Adper Easy One as dentin bonding agents. Cavities were restored with composite. Fourth experimental group was restored with resin modified glass ionomer cement (Vitremer). All specimens were thermocycled, stained with methylene blue dye and sectioned to evaluate dye penetration. Statistical analysis was done using Kruskall Wallis test and Mann-Whitney test with significant p-value <0.05 and result was expressed through sum of ranks.Results: At enamel margins, Adper Single Bond (mean?±SD 0.57?±0.73) 2 and Vitremer (0.43±0.63) showed the lowest mean leakage. Adper Easy One (1.83±1.15) showed highest mean leakage. At cementum margins, Vitremer showed lowest mean leakage (mean?±SD 0.47±0.63) and Adper Single Bond (2.97±1.22) 2 showed highest mean leakage.Conclusion: It can be concluded that in comparison with the dentin bonding agents used in this study Vitremer has a better sealing ability at both coronal (enamel) and apical (dentin/ cementum) margins.
