Study Reveals Fiber Reinforced Composites' Performance in Class II Restorations

Posted: September 8, 2025
A recent 18-month randomized controlled clinical trial compared the clinical performance of fibre reinforced resin composites to conventional nanohybrid resin composites in restoring Class II MOD cavities. The study, conducted at Cairo University, included 45 participants with carious lesions in vital posterior teeth. Outcomes were assessed using Modified USPHS criteria, with primary outcomes focusing on marginal adaptation, gross fracture, marginal discoloration, color match, and recurrent caries. The study revealed unexpected findings that challenge traditional assumptions about the efficacy of fibre reinforced composites in dental restorations. Results were statistically analyzed with significance set at P ≤ 0.016, showing potential implications for future dental restoration practices.
