Comparative Analysis Of Success Rate In Class II Cavities with Direct and Indirect Restorations - A Retrospective Analysis

Aim: An adhesive restoration is a substance capable of holding two surfaces in a strong and permanent manner. There are two strategies in restoring class II cavities- direct, indirect restorations. Indirect technique refers to fabrication of the restoration outside the oral cavity in the laboratory following which it is luted to the tooth with resin cement. The aim of this current study was to analyse and compare direct, indirect restorations done in class II cavities. Materials and Methods: As it was retrospective analysis, data collected from Saveetha Dental College and Hospitals, Chennai and evaluated the patients who received direct and indirect restorative procedures for class II cavities. Data was evaluated from patient's records from June 2019 to March 2020 and the data consisted of 548 patients. Inclusion criteria consisted of patients aged 18-70 years who received direct restorative procedures such as composite or amalgam restorations,patients who received indirect restorative procedures such as metal or ceramic inlay for class II cavities. Exclusion criteria consisted of patients who have received restorations other than class II cavities, sealants, temporary restorations and endodontic procedures. Results: In this study of 309 class II restorations (156 males,153 females with a mean age group of 30 years)were included. Group A (direct restorations) has higher preference rate and success rate over group B (indirect restorations) comprising class II cavitieswith p value<0.05. Conclusion: The clinical success rate of direct restorations were higher than that of indirect restorations in class II cavities.
