Evaluate the Efficacy of Endodontic Microsurgery on Teeth Having Undeveloped Root Apex Failed in Non-surgical Treatment with Periapical Inflammation

Abstract

Abstract Background: To evaluate the efficacy of endodontic microsurgery on teeth with undeveloped root apex and periapical inflammation caused by an abnormal central cusp fracture due to failed nonsurgical treatment. Methodology: We performed endodontic microsurgery on 80 teeth in 78 patients with undeveloped root apex and periapical inflammation caused by an abnormal central cusp fracture due to failed nonsurgical treatment. All patients were clinically and radiologically examined 1 year after surgery, and the data were statistically analyzed using the SPSS 27.0 software package. Results: Of 80 teeth in 78 patients, periapical lesions disappeared in 77 teeth at the 1-year postoperative follow-up, with a success rate of approximately 96.3% (77/80). Sex, age, extent of periapical lesions, and the presence of the sinus tractdid not affect the efficacy of endodontic microsurgery. The differences between groups were not statistically significant (P > 0.05). Conclusions: On failure of nonsurgical treatment in teeth with undeveloped root apexand periapical inflammation caused by an abnormal central cusp fracture, endodontic microsurgery may be a good clinical treatment option.
