Abstract
Background: The selection of core build-up material is a critical factor influencing the long-term success of endodontically and surgically treated teeth restored with crowns.
Objective: To evaluate the effect of different core build-up materials on the clinical longevity and survival rate of restored teeth.
Methods: A retrospective cross-sectional study was conducted using clinical records from January 2015 to December 2022. A total of 276 teeth treated with root canal therapy or surgical endodontics and restored with crowns were analyzed. Teeth were categorized based on the core material: resin composite, glass ionomer cement (GIC), or amalgam. Survival rates were evaluated over a minimum follow-up period of three years.
Results: Teeth restored with resin composite cores demonstrated the highest survival rate (85.4%) followed by amalgam (72.2%), whereas GIC cores showed the lowest survival (61.5%) (p<0.05). Failures were predominantly due to catastrophic fractures and recurrent decay.
Conclusion: Resin composite core build-ups were associated with better longevity and clinical performance. The mechanical properties and bonding ability of composite appear to contribute to improved structural reinforcement of treated teeth.
