Retrospective Analysis on Type of Cavity Preparation Done for Class II Mesio Occlusal Composite Restorations
Objective: Controversy exists regarding cavity preparation for restoration of interproximal caries in posterior teeth in terms of preserving the tooth structure. This study aimed to determine the type of cavity preparation in class II mesio occlusal composite restoration. Materials and methods: Study samples of 800 cases were obtained from the data of 86000 patients between March 2020 and March 2021. Statistical software used for analysis was the SPSS (statistical package for the social sciences) which is designed by IBM and the statistical tests used were frequency tables along with bar graphs to analyse and compare the obtained results. The obtained data was tabulated in excel systematically. Data was then entered in the SPSS analysis software and descriptive analysis and correlation statistics performed. The obtained results were tabulated and graphically represented. Results: Results from the study revealed that occurrence of class II cavity was higher among the male population 53.4% when compared with female population 46.6%.Most of the class 2 cavity preparation was done in the maxillary region 66.8% and in the mandibular region is 31.3%.Conservative like cavity preparation was higher 77% and conventional preparation is 14.7% and box only preparation is 6.9% and in slot preparation is 1.7%. Conclusion: Further evaluation based on bigger sample size, multi-location studies with details on the type of cavity design could be helpful. The findings of the study showed that Conservative like cavity preparation was commonly occurring in the male population and maxillary posterior region has a higher incidence of conservative preparation.
