Başlangıç Okluzal Çürüklerin Tedavisinde Kullanılan İki Farklı Nanokompozitin Klinik Performanslarının Değerlendirilmesi: İki Yıllık Takip

Abstract

Clinical performance of two different nano composites in initial occlusal caries : two years results. Hacettepe University Health Science Institute PhD Thesis in Restorative Dentistry, Ankara, 2015. The purpose of this study was to evaluate the two-year clinical performance of one condansable nano composite and one flowable nanocomposite in minimal occlusal cavities. Patients were selected from who visiting the Hacettepe University School of Dentistry Department of Restorative Dentistry for the teratment of occlusal caries (age range 18-30 years). At the beginning of treatment, teeth were diagnosed by visual inspection with a mirror and lesions were evaluated with periapical and bitewing radiographs. After that to achieve standardization measurements were made with the DIAGNOdent Pen. Twenty male andtwenty-three female subjects participated to study. A total of 356 occlusal cavities were restored with condansable nano composite (Quixfil, Dentsply) and flowable nano composite (SureFil SDR Flow, Dentsply) according to manufacturers' instructions. All restorations were placed by one operator. The restorations were evaluated clinically within 1 week after placement and after 6., 12., 18., 24. months using modified USPHS criteria by one examiner. At the end of 24 months; in 38 patients 316 restorations were evaluated. Statistical analysis was completed using Pearson Chi-square, Fisher- Exact and Cochran Q tests (p<0,05). No statistically significant differences were found between two resin composites (p>0.05). There were significant differences between time zones with each restoration group for marginal adaptaion, marginal discoloration, anatomic form, post operative sensitivity (p<0.001). Interms of Retantion, color match, seconder caries, surface texture no significant differences have been found in each restorative materials groups (p>0,05). It was concluded that; different types of resin composites demonstrated acceptable clinical performance in initial occlusal caries.
