A 1-year comparative evaluation of clinical performance of conventional direct composite restoration technique with a novel "custom shield" technique in class I compound lesions - A randomized clinical study.

Aim: The aim of the study is to evaluate and compare the 1-year clinical performance of conventional direct composite restoration technique with a novel "custom shield" technique in class I compound lesions.
Subjects and Methods: After ethical approval, 72 patients who signed the informed consent form participated in the study. They were divided into two groups - Group A: Conventional direct composite restoration ( n = 36) and Group B: Composite restoration using custom shield technique ( n = 36) by computer randomization. In Group A, composite restoration was performed by the incremental layering technique. In Group B, restoration was performed using a novel custom shield and occlusal stamp along with the incremental layering technique. Patients were evaluated using the modified USPHS criteria by blinded evaluators for 1 year.
Statistical Analysis: Chi-square test and Friedman test using SPSS version 21.0.
Results: A statistically significant difference was obtained for marginal adaptation ( P = 0.024), retention ( P = 0.23), surface texture, and anatomic form ( P < 0.001), and time taken to perform the procedure for Group B was higher than Group A.
Conclusion: Conventional composite restoration and custom shield technique can be successfully used in class I compound lesions with custom shield technique having a higher edge over the conventional technique.
Competing Interests: There are no conflicts of interest.
