Periapical Healing in Single-visit Endodontics under General Anesthesia in Special Needs Patients

초록

Introduction: The aim of this study was to determine the prognostic factors of periapical healing of teeth after singlevisit nonsurgical endodontic treatment under general anesthesia in special needs patients. Methods: This retrospective study collected 448 teeth from 241 patients (mean age = 27.4 years, standard deviation = 13.9 years). A total of 271 teeth (60.5%) with clinical and radiographic follow-up records longer than 12 months (mean [standard deviation] = 56.1 [27.9]) were included in the outcome analysis. Demographic, systemic, and dental information about the cases were compared between the healed and nonhealed groups using the Pearson chi-square test. Factors contributing to periapical healing were determined with multivariate logistic regression analysis. Results: Complete periapical healing without clinical signs was observed in 221 teeth (81.5%), uncertain healing with decreased size of the periapical lesion was shown in 43 teeth (15.9%), and no reduction in lesion size was observed in 7 cases (2.6%). In the multivariate analysis, diet type, oral hygiene maintenance, pulp vitality, and root filling length were detected as contributing factors for complete resolution of periapical lesions (P <.05). Conclusions: Successful outcomes of singlevisit endodontic treatment under general anesthesia were shown in special needs patients. The prognoses were influenced by the clinical circumstances of the patients and the preoperative conditions of their teeth.
