Objectives: The dawn of minimally invasive dentistry has led to the development of materials which rely on the use of effective adhesion to remaining tooth tissue. Despite making important advances, dentin bonding has to overcome hurdles with respect to structural heterogencity of dentin and long term stability of the bond. The primary mode of failure for adhesive restorations has been described as the loss of marginal adaptation and loss of retention. Methods: This in vitro study was undertaken to assess marginal adaptation and microleakage of Class V lesions using two cavity designs, a fifth generation dentin adhesive and a glass ionomer bonding agent-liner in extracted human molars, restored with composite resin restorations. Extracted permanent molars were divided into four groups (n=10). Class V cavities on buccal surfaces with retentive or non retentive features were prepared. A comparative dye leakage study was done between Syntac single component and Fujibond LC bonding agent, when cavities were restored with Heliomolar composite resin. 2% methylene blue dye was used to assess microleakage under stereomicroscope. The scores obtained were subjected to the Kruskal Wallis one-way analysis and Mann Whiteney U test. Results: Results of this study showed that the glass ionomer bonding agent-liner groups in both retentive and non-retentive cavities exhibited statistically significant (P<0.05) less microleakage as compared to the non-retentive dentin bonding agent group on the dentinal/cemental cavosurface margins. Conclusion: Within the limits of the study, it was concluded that the glass ionomer bonding agent-liner may be effective in reducing gingival microleakage in Class V situations with gingival margins in cementum and dentin.
