Area of Science:

  • Endodontics
  • Surgical Dentistry
  • Minimally Invasive Procedures

Background:

  • Periradicular surgery aims to treat persistent inflammation or infection at the root apex.
  • Traditional methods may lack optimal visualization, potentially affecting diagnostic accuracy and outcomes.
  • Endoscopic visualization offers magnified optical views, potentially improving periradicular surgery.

Purpose of the Study:

  • To evaluate the hypothesis that endoscopic periradicular surgery leads to improved clinical diagnostics and success rates.
  • To identify factors influencing the success of endoscopic periradicular surgery.

Main Methods:

  • A prospective study involving 114 teeth from 91 patients undergoing endoscope-assisted periradicular surgery between 2002 and 2003.
  • Pre-operative data recorded: tooth type, number of resected root-ends, root canal contents, clinical diagnosis, and surgery timing.

  • One-year post-operative follow-up assessing clinical and radiological findings for treatment success evaluation.

    • Main Results:

    • Treatment success was achieved in 91.8% of 110 evaluated teeth; failure occurred in 7.3%.
    • A learning curve effect was observed, with increasing success rates throughout the study period.
    • Periradicular surgery on molars showed a statistically higher rate of failure compared to other teeth.

    Conclusions:

    • Endoscopic periradicular surgery is a highly successful treatment modality, confirming the initial hypothesis.
    • The enhanced visualization provided by endoscopes improves diagnostic capabilities and surgical outcomes.
    • Continuous improvement in technique, indicated by the learning curve, further optimizes success rates.
