Summary
Dental restorations like crowns and proximal fillings are linked to a higher prevalence of furcation involvement in molars. Restored molars showed increased attachment loss, suggesting potential periodontal risks associated with dental work.
Area of Science:
- Dentistry
- Periodontology
- Restorative Dentistry
Background:
- Dental restorations, including crowns and proximal fillings, are common in molar teeth.
- Understanding the relationship between restorations and periodontal health, specifically furcation involvement, is crucial for patient care.
Purpose of the Study:
- To investigate the correlation between the presence of dental crowns (CR) or proximal restorations (RE) and furcation involvement (FI) in molar teeth.
- To assess the association between restorations and periodontal attachment loss (AL) and tooth mobility (MO).
Main Methods:
- Cross-sectional study of 134 periodontal maintenance patients.
- Clinical examination of first and second molars for CR, RE, FI, MO, and AL.
- Statistical analysis using Pearson chi-square and pair-difference t test.
Main Results:
- Molars with crowns or proximal restorations exhibited a significantly higher percentage of furcation involvement (P < 0.01).
- No significant difference in tooth mobility was observed between restored and non-restored molars.
- Mean probing periodontal attachment loss was greater in restored molars, with marginal significance (P = 0.051).
Conclusions:
- Dental restorations on molars, particularly crowns and proximal fillings, are associated with an increased prevalence of furcation involvement.
- Restored molars may experience greater periodontal attachment loss compared to non-restored teeth.
- The findings highlight a potential link between dental restorations and furcation defects, warranting further investigation and clinical consideration.
