Clinical Evaluation of the Effect of Direct and Indirect Composite Resin Restorations In Hypomineralized Permanent Molar Teeth: A Pilot Study

Aim: The purpose of this pilot study is to comparative evaluation of the clinical effectiveness of direct and indirect composite resin restorations in hypomineralized first permanent molars. Materials-Methods: A total of 20 hypomineralized first permanent molars in 10 children aged 7-11 were included for the study. Teeth were randomly divided into two groups according to the restoration type to be applied: direct or indirect composite resin restorations. Restored teeth were clinically evaluated at baseline, 6 and 12 months by modified United States Public Health Service (USPHS) criteria. Mann-Whitney U and Friedmann tests were used for statistical analysis of data. Results: During the 12-month follow-up period, although Alpha and Bravo scores were determined, no Charlie score was observed in both direct and indirect resin restoration groups. According to USPHS criteria scores, for each group, no significant difference was observed between follow-up periods (p 0.05). When the clinical success of direct and indirect composite resin restorations were compared, the scores of marginal adaptation, marginal discoloration and anatomical form of indirect composite resin restorations were observed to be better than direct composite resin restorations; however, this difference was not statistically significant (p 0.05). Conclusion: As a result of this pilot study observed that direct and indirect composite resin restorations in hypomineralized first permanent molars to have similar clinical effectiveness.
