Background: Dental restorations play a crucial role in preserving the structural integrity and function of posterior teeth. However, wear resistance remains a significant concern for these restorations.
Materials and methods: In this RCT, 120 participants with posterior tooth restoration needs were randomly assigned to two groups. Group A received conventional composite restorations, while Group B received NanoFilled Composite restorations. The restorations were placed according to standardized protocols. Wear resistance was assessed using a custom-designed chewing simulator, and the material wear was quantified using a profilometer. Patient-reported outcomes and clinical evaluations were also recorded at regular intervals over a 24-month follow-up period.
Results: The wear resistance of the NanoFilled Composite restorations (Group B) was significantly higher than that of the conventional composite restorations (Group A) after 24 months of follow-up (P < 0.05). Profilometer measurements revealed that Group B had an average wear depth of 0.15 mm, while Group A had an average wear depth of 0.25 mm. Patient-reported outcomes indicated higher satisfaction and comfort in Group B. Clinical evaluations also demonstrated that Group B restorations had better retention and marginal integrity.
Conclusion: This RCT demonstrates that NanoFilled Composite restorations exhibit superior wear resistance compared to conventional composite restorations when used in posterior teeth.
