Background: Fixed prosthodontics is a commonly used dental treatment that restores and preserves oral tissues. Marginal gaps at the tooth-restoration interface are an inevitable component of any fixed restoration and need to be sealed effectively. Luting cements are used to seal gaps and preserve the tooth from microbial invasion. 1 Failure of cements to seal gaps may result in an inflammatory response in the pulp and subsequent pulpal necrosis, which compromises the longevity of restorations. Aim of the study: To assess composite inlays by using different luting cements at different levels. Materials and methods: The present study was conducted in the Department of Conservative Dentistry and Endodontics of the Dental institutions. For the study, we selected 40 extracted premolar teeth free from any caries or structural anomaly. The teeth were randomly grouped into 2 groups with 20 teeth in each group. Standardized class II inlay box cavities were prepared on each tooth using high speed hand piece along with air and water spray. GROUP I –Multilink N as a luting agent and GROUP II- Multilink speed as a luting agent. The luting cements were mixed and applied as per the manufacturer’s instructions. The inlay was seated into the cavity and excess material was removed with scalers. The margins were light cured for 20 seconds as per the manufacturer’s instructions. Results: There were 20 teeth in each group I and II. The mean rank of microleakage for Group I teeth was 9.23 and for Group II teeth was 8.21. On comparing the results, it was found that results are statistically non-significant. Conclusion: Within the limitations of the present study, it can be concluded that the microleakage of composite inlay with luting cements Multilink N and Multilink speed are very minimal but there is not much difference between both the cements as per microleakage.
