Clinical Performance of Universal Adhesives

Study Overview
=================
Brief Summary
-----------------
Universal adhesive systems have recently been launched on the market, allowing dentists to select an adhesive strategy based on individual preferences and clinical conditions. These adhesives contain a primer/adhesive resin mix in a single bottle for multi-mode etch-and-rinse or self-etch applications. The aim of this study was to assess the clinical performance of two universal adhesives and a two-step self-etch adhesive on Class II restorations.

Detailed Description
-----------------
This study was a double-blind (evaluator and patient) randomized controlled clinical study with three study groups with an equal allocation. Two universal adhesives and one two-step self-etch adhesive were compared in Class II 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 esthetic property, marginal discoloration; in terms of function properties, fracture and retention, and marginal adaptation; in terms of the biological characteristics, post-operative sensitivity, and secondary caries 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 the Friedman test (p < 0.05).
