Clinical Evaluation of Bulk-fill Restorative Materials

Study Overview
=================
Brief Summary
-----------------
High-viscosity glass ionomer cements have been developed to improve the weak mechanical properties of glass ionomer cements, increase wear resistance and improve their limited indications. There are limited clinical studies on the use of high-viscosity glass ionomer cements in areas with large cavities bearing stress. The aim of this study is to compare the clinical performance of two different high-viscosity glass ionomer cements with a bulk-fill resin composite in different cavities.

Detailed Description
-----------------
This study was a double-blind (evaluator and patient) randomized controlled clinical study with three study groups with an equal allocation. Three different restorative materials were compared in Class I, II, and V restorations. The treated patients were called back for controls after one week, six months, and eighteen months. Restorations were evaluated clinically according to modified FDI criteria. In terms of marginal discoloration, fracture and retention, marginal adaptation, post-operative sensitivity, secondary caries, color match and difference criteria were examined. Clinical evaluation was performed by two qualified clinicians using a mirror and probe under reflector light. Clinicians were calibrated before the evaluation of restoration. Bite-wing radiographs were taken from the patients who were called for controls at 6-moth and 18-month to evaluate the formation of secondary caries. Differences between adhesives at each time period were evaluated using Fisher's Exact test. The effect of time on restorations was evaluated using Wilcoxon Signed rank test (p < 0.05).
