Summary
Periradicular surgery using microsurgical technology and ultrasonic root-end preparation achieved a 92.5% success rate over three years. This advanced endodontic treatment effectively healed teeth with failed root canals, promoting bone regeneration.
Area of Science:
- Endodontics
- Oral Surgery
- Radiology
Background:
- Failed conventional root canal treatments often require periradicular surgery.
- Microsurgical technology and ultrasonic preparation offer advanced techniques for endodontic surgery.
Purpose of the Study:
- To evaluate the long-term outcomes of periradicular surgery using microsurgical technology and ultrasonic root-end preparation.
- To assess the healing rates and success of endodontic surgical procedures.
Main Methods:
- 128 teeth with failed root canals underwent surgery using ultrasonic retrotips.
- Zinc oxide-EBA-reinforced material sealed the root end cavities.
- Radiological examinations were conducted at multiple intervals up to 36 months.
Main Results:
- A 92.5% overall success rate was observed in 120 evaluated teeth.
- Complete bone filling occurred in 94 cases, with 17 showing apical scar formation.
- Eighty teeth healed radiologically within 12 months; no significant differences were noted between tooth types.
Conclusions:
- Modern microsurgical endodontic procedures combined with specific root-end fillings demonstrate high success rates.
- The technique is effective for treating teeth with failed root canal treatments, leading to significant bone healing.
- The study supports the efficacy of these advanced surgical techniques in endodontics over a 3-year period.
