2016-09-08 16:53:21 | BioPortfolio

Summary

The aim of this study was to evaluate the clinical performances of nano-hybrid resin composite systems used for anterior diastema closure and tooth reshaping at 4 years in service using FDI Criteria.

Twenty-three patients with diastema problem were enrolled. Nano-hybrid resin composites to be used on each patient were randomly selected. Thirty-seven teeth (10 patients) were restored with Filtek-Z550 (3M/ESPE) in combination with Adper™ Single Bond 2 (3M/ESPE) in Group 1; whereas 39 teeth (13 patients) were restored with Charisma-Diamond (Heraeus Kulzer) in combination with Gluma2 Bond (Heraeus Kulzer) in Group 2, by two operators. Esthetic, functional and biological properties of the restorations were evaluated at baseline, 1-4 years using FDI Criteria establishing a score-range of 1-5. The data were evaluated using the Fisher's Chi-Square (p=0.05).

Description

The aim of this study was to evaluate the clinical performances of nano-hybrid resin composite systems used for anterior diastema closure and tooth reshaping at 4 years in service using FDI Criteria.

The study protocol was approved by the Ethical Committee of Hacettepe University, Ankara, Turkey and the Ethical Committee of Ministry of Health (protocol HEK KA-14004). A total of 23 patients (6 male, 17 female, mean age: 31.27) with maxillary anterior midline or multi-diastema problem received 76 direct composite resin restorations.

The teeth to be restored were first cleaned with pumice-water slurry using a rubber cup. The appropriate shade of restorative material was selected using a standard VITAPAN® Classic shade guide and initial intraoral photographs were taken. Teeth were then isolated using cotton rolls and Mylar strips were placed with the help of wedges interproximally to achieve a smooth and overhang free restoration outline in the cervical area and to form final restorations. The surfaces to be restored were etched using 35% phosphoric or orthophosphoric acid for 30 s according to the restorative system used. The etched surfaces were rinsed and dried. Nano-hybrid resin composite systems to be used on each patient were randomly selected. Thirty seven teeth of 10 patients were restored with Filtek-Z550 (3M/ESPE, St. Paul, MN, USA) in combination with Adper™ Single Bond 2 (3M/ESPE, St. Paul, MN, USA) etch&rinse adhesive; whereas 39 teeth of 13 patients were restored with Charisma-Diamond (Heraeus Kulzer, GmbH, Germany) in combination with Gluma2 Bond (Heraeus Kulzer, GmbH, Germany) etch&rinse adhesive by two operators. Materials were used according to the manufacturers' instructions. Two calibrated observers who were blinded to the objective of this study performed the evaluations. For maximum validity, the observers were calibrated by using the web-based training and calibration tool www.e-calib.info recommended by FDI. Both observers evaluated the esthetic, functional and biological properties of the restorations independently at baseline, 1-2-3 and 4 years using FDI Criteria establishing a score-range of 1-5 (1-Clinically excellent/very good, 2-Clinically good, 3-Clinically sufficient/satisfactory, 4-Clinically unsatisfactory and 5-Clinically poor). After data collection, in case of discrepancies in scoring, restorations were evaluated again, a consensus was reached and this was accepted as the final score.

Statistical analysis was performed with SPSS 15.0 software. To compare the performance of restorative materials according to FDI criteria over the study period, the Fisher's Chi-Square test was used. The Cochran's Q test was then used to compare the 1-2-3 and 4-year scores of each material with baseline scores to evaluate the changes of each dependent group by the time. Survival curves were obtained using Kaplan-Meier method. p values less than 0.05 were considered to be statistically significant in all tests.
