？ürüksüz Servikal B？lge Di？ Sert Doku Kay？plar？nda Universal Adeziv Kullan？larak Yap？lan Restorasyonlar？n FDI Kriterlerine G？re De？erlendirilmesi

Aim: This study aimed to compare the different application modes of universal bonding agents on non-carious cervical lesions. Material and method: Twenty-five patients without any systemic disease and with good oral hygiene, having at least 20 teeth and 6 non-carious cervical lesions treated using a universal adhesive and nano hybrid composite material were selected among the patients who were treated at Department of Restorative Dentistry, Eski？ehir Osmangazi University between January 2015-March 2015. The 246 restorations included in the study were evaluated according to FDI criteria at 18-month follow-up. Each bonding mode was analyzed by Friedman analysis and Dunn’s binary comparison test. Relation between the categorical mode variate and the scores were analyzed by Pearson Chi-square analysis (p=0.05). Results: There was no significant difference between the application modes at 18-month period regarding surface luster, surface staining, color match and translucency, esthetic anatomical form, marginal adaptation, post operative sensitivity, caries recurrence, erosion, abfraction, tooth integrity and periodontal response. Marginal discoloration, fracture and retention, and the patient's view criterias showed a significant difference in terms of the application modes at 18-month follow-up. Esthetic anatomic form, patient's view, and tooth integrity were not significantly different between evaluation periods (p>0.05). Conclusion: SE mode showed significantly worse scores than that of TE and SLE modes. Further studies are needed to evaluate the clinical performance of universal adhesives
