Summary
Extensive direct composite restorations in molars demonstrated acceptable clinical performance over three years. However, male patients experienced a higher failure rate for these dental restorations compared to female patients.
Area of Science:
- Dentistry
- Dental Materials
Background:
- Direct composite restorations are widely used in posterior teeth.
- Assessing the long-term clinical performance of extensive restorations is crucial.
Purpose of the Study:
- To evaluate the clinical performance of extensive direct composite restorations in molars.
- To determine the influence of restoration extent and patient factors on performance.
Main Methods:
- Seventy-four patients with multi-surface molar restorations using nano-filled composite were selected.
- Clinical evaluations were performed at baseline, 1 year, and 3 years using modified USPHS criteria.
- A topographic system was developed to classify extensive posterior restorations.
Main Results:
- The 3-year survival rate for extensive direct posterior composite restorations was 87.7%.
- A mean annual failure rate of 4.2% was observed.
- Gender was a significant factor (p=0.022), with men showing higher failure rates.
Conclusions:
- Extensive direct posterior composite restorations exhibit acceptable clinical performance after three years.
- Restoration survival was not significantly influenced by age, caries risk, or restoration extension.
- Male gender was associated with a higher failure rate in these restorations.
