Evaluation of surgical treatment outcomes for dentigerous cysts using the Partsch II procedure

Objective: This study evaluated the postoperative outcomes of the Partsch II procedure (primary enucleation) in patients with dentigerous cysts treated at the Department of Odonto-Stomatology, Bach Mai Hospital, Vietnam, at 1-week and 3-month follow-ups. Subjects and Methods: A case series study was conducted on 31 patients diagnosed with dentigerous cysts and treated surgically using the Partsch II technique from August 2017 to August 2018. Clinical parameters assessed included swelling, pain, neurosensory disturbances, infection, and radiographic healing. Data were analyzed using SPSS 16.0, with statistical significance set at p < 0.05. Results: At 1 week postoperatively, 78.4% of cases showed good outcomes, 18.9% had mild complications (edema, transient paresthesia), and 2.7% exhibited poor outcomes (infection with flap dehiscence). By 3 months, 94.6% achieved complication-free healing, while 5.4% had residual hypoesthesia or inflammatory drainage. No recurrences were observed radiographically. The complication rate was significantly lower than comparative studies (p = 0.013 at 1 week; p = 0.007 at 3 months). Conclusion: The Partsch II procedure demonstrated high efficacy, with minimal recurrence and manageable complications. Its single-intervention approach reduced treatment duration and costs, supporting its suitability for dentigerous cyst management.
