Sažetak
Aim: The aim of the present study was to investigate the reasons for placement and replacement of defective resin-based composite (RBC) restorations and the associations between placed and replaced composite restorations by gender, type of cavity, tooth type and longevity of replaced ones. Materials and Methods: Study population consisted of 700 patients, 310 males and 390 females, aged 18 to 58 years old who sought dental treatment in a private practice in Greece. All subjects were clinically examined and the number of decayed teeth (primary caries) and failed-restored teeth was calculated for each patient. In addition the association between placed and replaced composite restorations and the following aspects was assessed: gender, cavity type and tooth type. Statistical analysis was accomplished by using chi-square test. Results: The total number of restorations placed were 904, 524 (57.7%) were placed for first time while 380 (32.3%) were replaced. Primary caries was the most frequent reason for the placement of new composite resin restorations (63%) followed by tooth discolouration (15%) and tooth fracture (14%) while the main reasons for replaced resin composite restorations were secondary caries (42%), discolouration (32%) and loss of filling (20%). The median longevity of the replaced resin composite restorations was approximately 4 years (42%). Conclusions: Dental caries, primary and secondary, was the principle reason for placed and replaced resin composite restorations followed by tooth discolouration. Therefore, patients at a high risk of developing caries may require more frequent dental care to ensure that new and recurrent carious lesions are prevented.
