Summary
Pathologic tooth migration (PTM) affects over half of periodontal patients and is strongly linked to bone loss, tooth loss, and gingival inflammation. These factors, especially bone loss, significantly increase the likelihood of PTM development.
Area of Science:
- Periodontology
- Epidemiology
- Dental Public Health
Background:
- Pathologic tooth migration (PTM) is a concern in periodontal disease.
- Understanding PTM's contributing factors is crucial for effective treatment and prevention.
Purpose of the Study:
- To determine the prevalence of PTM in periodontal patients.
- To investigate the association between PTM and factors like bone loss, tooth loss, and gingival inflammation.
Main Methods:
- Cross-sectional epidemiological study of 852 periodontal patients.
- Statistical analysis using Wald and Mantel-Haenszel tests, including odds ratio calculations.
- PTM defined as new or increased diastema in the upper anterior sextant.
Main Results:
- PTM prevalence was 55.8% among the studied patients.
- PTM showed significant statistical association with bone loss (p<0.001), tooth loss (p<0.001), and gingival inflammation (p<0.001).
- Odds ratios indicated increased PTM probability with higher bone loss, tooth loss, and gingival index scores.
Conclusions:
- No single factor independently predicts PTM; a combination is key.
- Bone loss is the primary factor associated with PTM, followed by tooth loss and gingival inflammation.
- The association of tooth loss and gingival inflammation with PTM increases as bone loss becomes more severe.
