Development and Treatment of Radicular Cyst in Pediatric Patient-Case Report.

Inflammation in the periapical area of primary teeth can affect the development and eruption of permanent teeth. In an asymptomatic course, they are detected accidentally during routine examinations. In such cases, they often reach significant dimensions and cause irreversible changes. This report presents the case of a 9-year-old boy with a radicular cyst in the mandible, resulting in the displacement of both premolar tooth buds. To address the inflammation, facilitate the proper eruption of the impacted teeth, and prevent adjacent teeth from shifting, the primary molars were extracted. Marsupialization was performed under general anesthesia, followed by the fabrication and placement of an obturator. Two months after treatment, the displaced tooth buds began aligning along the natural eruption pathway. By the 8-month follow-up, the premolars had successfully erupted into their proper positions in the oral cavity. Marsupialization combined with the use of an obturator is an effective first-line treatment for radicular cysts in pediatric patients, offering a conservative approach that promotes natural tooth eruption while preserving the surrounding dentition.
