Background: Retention of a primary tooth due to congenital absence of its permanent successor presents a unique restorative and endodontic challenge. In such situations, preservation of the retained primary tooth for as long as possible is desirable to maintain function, arch integrity, and alveolar bone support. Although gutta-percha (GP) is conventionally used as an obturating material in permanent teeth, its use in primary teeth is uncommon because of the physiologic root resorption necessary for the exfoliation of primary dentition. However, in cases where the permanent successor is congenitally absent, gutta-percha may serve as a suitable non-resorbable obturating material.
Case Report: This case report describes the management of a 15-year-old female who presented with recurrent spontaneous pain associated with a retained mandibular left primary second molar. Clinical and radiographic examination revealed dental caries with irreversible pulpitis in tooth 75 and congenital absence of the permanent mandibular left second premolar (35). A two-visit pulpectomy was performed, and the canals were obturated with gutta-percha. The tooth was subsequently restored with glass ionomer cement and a stainless-steel crown. Clinical and radiographic follow-up over 12 months demonstrated the absence of pain, swelling, mobility, sinus tract formation, or periapical pathology, indicating a successful treatment outcome.
Conclusion: This report highlights the potential use of gutta-percha as an obturating material in retained primary teeth without permanent successors, where long-term tooth preservation is desired.
