Effect of Modeling Resin on Anterior Direct Composite Veneer

the study will be conducted to evaluate the clinical performance of direct Nanohybrid resin composite veneer restorations applied with or without modeling resin

ChatGPT This study aims to investigate the impact of modeling resin on the clinical performance of direct nanohybrid resin composite veneer restorations in anterior teeth. Resin composites are widely used in dental restorations due to their aesthetic qualities, but issues like discoloration and surface roughness can affect their longevity and patient satisfaction. Modeling resin, used to aid in composite placement and sculpting, has become common, but concerns exist regarding its effects on composite properties, particularly long-term color stability. The research will employ a randomized controlled trial design with a two-arm parallel approach. Adult patients (18-45 years) with anterior tooth defects suitable for composite veneer restoration will be recruited. The intervention group will receive nanohybrid resin composite with modeling resin, while the comparator group will receive the composite without modeling resin. Outcomes will be assessed using modified USPHS criteria, including color stability, color match, anatomical form, marginal adaptation, marginal discoloration, retention rate, presence of secondary caries, and postoperative sensitivity, at baseline and at follow-up intervals of 1, 3, 6, and 12 months. Statistical analysis will involve independent t-tests for intergroup comparisons and repeated measures ANOVA for intragroup comparisons, with a significance level set at 0.05. The study aims to determine if the use of modeling resin influences the clinical outcomes of resin composite veneer restorations. Ethics approval will be obtained, and confidentiality of participant data will be strictly maintained throughout the study period. Overall, this research seeks to provide insights into optimizing the application of resin composites in dental practice to enhance patient outcomes and satisfaction
