Causative analysis,prevention and treatment on failure of endodontic microsurgery
Based on the literature,this paper systematically reviews the failure cases of endodontic microsurgery in the past 15 years.according to the time point:short-term and long-term failuresthe reasons for the failures are analyzed and classified into two categories.Incorrect diagnosis,unreasonable treatment plans,and non-standard surgical procedures lead to short-term failures,while long-term failures are mainly due to secondary vertical root fracture,other diseases,imperfect surgical procedures,and severe periodontal disease.Corresponding treatment plan is proposed,including error correction,extraction,and re-surgery.Prevention strategies include establishing correct diagnosis,selecting appropriate cases,developing reasonable treatment plans,and implementing standardized procedures to avoid short-term failures,reduce long-term failure,to improve the success rate of endodontic microsurgery,effectively treat pulp and periapical diseases,and preserve healthy natural teeth.
