    Background: Esthetic concerns are the prime focus in modern restorative dental practice. Composite resin restorative materials have played crucial roles in establishing esthetics in many clinical situations. However, they are also prone for the marginal discrepancy and microleakage. Bonding agents are used to minimize this phenomenon to improve the success of the restorations. Aim: This study is to assess the marginal adaptation (MA) of nanohybrid composite resin with two 7th generation dentin bonding agents. Materials and Methods: A total of 40 extracted human maxillary premolars were cleaned, processed, mounted, and divided into two experimental Groups A and B. Class V cavities were prepared in extracted teeth with the gingival margin on the dentin and the incisal margin on the enamel. The cavities were restored with a nanohybrid composite resin (Swiss Tec Composite, Coltene Whaledent, USA) using the experimental self-etching adhesives, Group A - (Bond Plus SE, Medicept Dental, UK) and Group B - (Kerr OptiBond, Heraeus Kulzer, Germany). After that, the restorations were light cured, finished and polished. After thermocycling, the MA was analyzed using scanning electronic microscopy (SEM) (SEM, ×600 magnification). The outcome measure is the widest distance between the restoration and tooth structure in the cervical margins expressed in the micrometer. The discrepancy in each margin was recorded, tabulated and analyzed. Results: The mean discrepancy between tooth structure and restoration in Group A was 3.35 ± 0.31 um and for Group B was 3.67 ± 0.24 um. An independent sample t-test was used to analyze the data. A statistically significant difference was observed between the two groups (P < 0.05). Conclusion: Kerr OptiBond showed higher means of gaps than Bond Plus SE in the cervical margins. Even though a statically significance was observed between the two bonding agents, clinical significance may not be altered.
