Apically-positioned flap surgery significantly reduced periodontal pocket depth more effectively than modified Widman flap surgery. Neither surgical approach completely eliminated periodontal pockets, highlighting the need for post-operative measurements to ensure intended flap placement.

Area of Science:

  • Periodontology
  • Oral Surgery
  • Regenerative Medicine

Background:

  • Periodontitis is a common inflammatory condition affecting the gums and supporting bone.
  • Surgical interventions like modified Widman flap and apically-positioned flap are used to treat moderate to severe periodontitis.
  • Comparing the efficacy of different surgical techniques is crucial for optimizing treatment outcomes.

Purpose of the Study:

  • To compare the effectiveness of modified Widman flap surgery versus apically-positioned flap surgery in treating adult-type periodontitis.
  • To evaluate the reduction in periodontal pocket depth immediately following each surgical procedure.
  • To assess the consistency between intended and actual flap placement in surgical periodontal treatment.

Main Methods:

Related Experiment Videos

  • A comparative study involving 14 patients with moderate to severe periodontitis.
  • Seven patients received modified Widman flap surgery (210 sites), and seven received apically-positioned flap surgery (210 sites).
  • Periodontal sounding depth measurements were recorded before and immediately after surgery for all treated sites.

    • Main Results:

    • Apically-positioned flap surgery resulted in a greater mean reduction in sounding depth (from 4.77 mm to 2.46 mm) compared to modified Widman flap surgery (from 4.89 mm to 3.42 mm).
    • Neither surgical technique achieved complete eradication of all periodontal pockets.
    • Inconsistent flap placement was observed, with apically-positioned flaps often placed significantly above the bone crest.

    Conclusions:

    • Apically-positioned flap surgery appears more effective in reducing periodontal pocket depth compared to modified Widman flap surgery.
    • The variability in flap placement underscores the importance of immediate post-operative measurements to validate surgical technique execution.
    • Further research may be needed to refine surgical techniques and ensure consistent outcomes in periodontal therapy.
