Summary

Apical surgery can cause gingival recession and attachment loss, primarily within the first year. Long-term periodontal changes are influenced by patient factors and healing outcomes.

Area of Science:

  • Periodontology
  • Oral Surgery
  • Clinical Dentistry

Background:

  • Most studies on apical surgery focus on periapical healing.
  • This research investigates long-term periodontal outcomes following apical surgery.

Purpose of the Study:

  • To assess long-term changes in periodontal parameters after apical surgery.
  • To identify factors influencing these periodontal changes.

Main Methods:

  • Collected data on probing depth (PD), gingival margin (GM), and clinical attachment level (CAL) at baseline, 1 year, and 5 years post-surgery.
  • Analyzed changes in PD, GM, and CAL over time.
  • Evaluated the influence of patient, tooth, and treatment covariables.

Main Results:

Related Experiment Videos

  • Significant gingival margin recession (0.29 mm) and clinical attachment loss (0.20 mm) were observed within the first year at facial sites.
  • No significant periodontal changes occurred between 1 and 5 years.
  • Incision technique impacted early changes; age, smoking, and healing influenced later changes.

Conclusions:

  • Patients should be aware of potential gingival recession and attachment loss post-apical surgery.
  • Surgery-related factors influence early changes, while patient and healing factors affect longer-term outcomes.
