Aim: This study analysed the frequently displaced class 2 restorations in the posterior teeth. Materials and method: A total of 1568 patients who have undergone class 2 composite restorations from June 2020- March 2021 were evaluated. Patient details like age, gender, teeth no, surfaces involved, cause for replacement were included. The prevalence of frequently displaced class 2 restorations was determined. The collected Data was analysed using SPSS. Results: Of the 1568 patients that were analysed 44.25% were in the age group 31–45 yrs. There were 53% men and 47% women included in the study The majority of the displaced restorations were class 2 mesio occlusal [MO] with 85% followed by 8.32% MOD and 5.81% Disto- occlusal. Over 50% of the study population had dislodged upper molar restorations followed by 28.93% lower molar restorations. The association between the type of restorations and survival rate was found to be highly significant, p=0.001. Conclusions: The present study reported a high incidence of displacement in the restoration in the mesio occlusal surfaces, especially on the molars. The most common cause of dislodgement was found to be fracture and secondary caries. This study demonstrated that a wide variation of risk factors on the practice, patient, and tooth levels influences the survival of class II restorations. To provide personalized dental care, it is important to identify and record potential risk factors. Therefore, we recommend further clinical studies to include these patient risk factors in data collection and analysis.
