Overview

Retrospective clinical study shows survival rates of indirect restorations in adults, indicating smoking as a significant risk factor.

Key Points

  • Lithium disilicate restorations showed a survival rate of over 90% after 5 years, dropping moderately thereafter.
  • For composite restorations, survival rates started at 94% but fell below 60% after 8.2 years.
  • This analysis utilized the Kaplan-Meier method for survival evaluation, alongside Cox regression for risk factor assessment.
  • The findings suggest that smoking may increase the risk of restoration failures, warranting further investigation.
