Retrospective Study On The Outcomes Of Apicoectomy Without Retrograde Filling For Periapical Inflammatory Cysts
Main Article Content
Abstract
Background: Radicular cysts, common inflammatory lesions related to dental pulp, often necessitate apicoectomy when standard root canal therapy fails. This study explores long-term outcomes of apicoectomy on both inflammatory and non-inflammatory cysts, specifically evaluating the necessity of retrograde filling. Materials and Methods: Data from patients at Kalinga Institute of Dental Sciences and various clinics in Odisha (July 2015 - July 2024) were analyzed. Inclusion criteria involved patients over 20 years who underwent root canal therapy prior to apicoectomy. Clinical outcomes were assessed through symptoms and follow-up cone-beam computed tomography (CBCT). Results: A total of 246 teeth were analyzed (mean age 43.2 ± 13.2 years). Apicoectomies were performed on 171 inflammatory and 75 non-inflammatory cysts, with retrograde filling in 36 and 5 cases, respectively. Over an average follow-up of 3.6 ± 2.3 years, no recurrences occurred, and only 1.2% of non-retrograde filled teeth showed complications. Conclusion: Apicoectomy provides favorable long-term outcomes for both cyst types, indicating that retrograde filling may not be essential for success.
