| Research Abstract |
Survival analysis showed that at least 60% of resin composite restorations survived more than 10 years. Operator-, patient-, material- and tooth-factors related to the longevity of restorations. Clinical trials demonstrated that the incidence of marginal staining increased with time, but most of the stains were clinically acceptable up to 5 years. Questionnaire study revealed that gender and clinical experience of dentists, age and caries risk of patients, clinical characteristics of caries, and location and the extent of marginal staining had a great influence on decision-making in restorative dentistry, such as restorative treatment thresholds for caries and criteria for replacement.
