Summary
Periodontal disease is an increasing cause of tooth loss, especially in those with attachment loss, bone loss, and smoking habits. Advanced periodontitis significantly impacts tooth mortality in a small population segment.
Area of Science:
- Dentistry
- Periodontology
- Epidemiology
Background:
- Dental caries has historically been the primary cause of tooth loss.
- Recent epidemiological trends indicate a rise in tooth loss attributed to periodontal disease.
Purpose of the Study:
- To analyze the factors contributing to tooth loss due to periodontal disease.
- To identify risk factors and patterns associated with periodontal tooth mortality.
Main Methods:
- Review of epidemiological studies and long-term maintenance data.
- Analysis of factors such as attachment loss, bone height, and smoking.
- Examination of tooth types most frequently lost and reasons for extraction.
Main Results:
- Initial attachment loss, reduced bone height, and smoking significantly increase tooth mortality risk.
- A strong correlation exists between smoking, periodontal disease severity, and tooth loss.
- Molars are most frequently lost in long-term studies, primarily due to mobility and furcation involvement.
Conclusions:
- Periodontal tooth mortality is strongly linked to periodontal attachment loss.
- Advanced periodontitis affects a minority of the population but contributes significantly to tooth loss.
- Periodontal surgery showed no significant benefit in retaining teeth for high-risk individuals.
