Clinical Evaluation of Two Low-shrinkage Composites

Hacettepe University18 enrolled

Overview

Patients with 4 occlusal lesions in molar teeth will be included. Occlusal cavities will be prepared either by Er,Cr:YSGG laser (LS) or conventional diamond bur (BR). Cavities will be restored with Filtek Silorane (3M-ESPE) (SR) and with Kalore (GC) (KR) according to the manufacturers' instructions. All restorative procedures will be performed by one operator and the restorations will be examined by two evaluators according to the FDI (World Dental Federation) criteria at baseline and at 6-month, 1-, 2-,3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-year. Patients' satisfaction about the preparation methods will be evaluated with a survey. Pearson Chi-Square test will be used for statistical analyze(p=0.05).
