About

To evaluate and compare the 2-year clinical performance of Class V restorations using various restorative systems with ion-releasing and non-ion-releasing composites, utilizing fluoride-free and fluoride-releasing universal adhesives for bonding

Full description

The experimental design description adhered to the guidelines provided by the Consolidated Standards of Reporting Trials (CONSORT) statement. The present study is planned as a double-blinded randomized clinical trial, ensuring that both the patients and the examiner are unaware of the treatment allocation. The trial will follow a parallel design. A total of one hundred adult patients, who are seeking dental treatment, will be enrolled in the study. The participants will be recruited from the Operative Department clinic at the Faculty of Dentistry, University of Mansoura. The study will focus on one hundred Class V restorations.

No active advertisement will be used for participant recruitment, and instead, a convenience sample will be formed. Prior to participating in the study, each patient will be required to provide informed consent by signing a consent form. The study is scheduled to be conducted from November 2023 to November 2025. The form and protocol of the study will be approved by Mansoura University's ethics committee before initiation.

To determine the appropriate sample size, previous studies examining the clinical success rate of posterior class V restorations restored with ion-releasing materials were considered. These studies reported a 100% success rate at a two-year follow-up. Based on various parameters, including a significance level of 5%, a test power of 80%, and an equivalence limit of 15%, the sample size was calculated. Considering a potential dropout rate of 20%, a sample size of 100 subjects was determined to be suitable.
