Periodontal healing after impacted lower third molar surgery. A retrospective study
International Journal of Oral Surgery
|February 1, 1985
Summary
Lower third molar surgery can negatively impact periodontal tissues, leading to plaque, gingivitis, and pockets, especially on the distal surface of the second molar. Long-term follow-up reveals significant bone loss and deep pockets post-surgery.
Area of Science:
- Dentistry
- Periodontology
- Oral Surgery
Background:
- Impacted or semi-impacted lower third molars often require surgical intervention.
- The surgical removal of lower third molars can potentially affect the health of adjacent periodontal tissues.
Purpose of the Study:
- To evaluate the long-term effects of lower third molar surgery on periodontal tissues.
- To assess the incidence of plaque, gingivitis, periodontal pockets, and alveolar bone loss post-surgery.
Main Methods:
- A retrospective study of 215 cases involving lower third molar surgery.
- Post-operative examinations conducted 2 years after surgery.
- Clinical assessments (plaque, gingivitis, pockets) and radiographic evaluations (alveolar bone level).
Main Results:
- Higher prevalence of plaque, gingivitis, and pockets on the distal surface of the second molar.
- Two years post-surgery, 43.3% of cases had pocket depths >7 mm.
- Two years post-surgery, 32.1% of cases showed intrabony defects >4 mm.
Conclusions:
- Lower third molar surgery is associated with increased periodontal issues, particularly around the second molar.
- Significant periodontal pocketing and bone loss can persist 2 years after surgery.
- Factors influencing periodontal healing require further investigation.
