Dens invaginatus is a developmental anomaly resulting from the infolding of enamel and dentin into the dental pulp. Oehlers' Type IIIa dens invaginatus poses significant challenges due to its intricate anatomy and frequent association with immature teeth. This case report outlines the nonsurgical management of a nonvital immature maxillary central incisor with Type IIIa dens invaginatus, presenting with a chronic apical abscess and a history of trauma to the associated primary incisor. Treatment involved thorough chemomechanical debridement followed by bio-obturation using calcium-enriched mixture cement. Regular follow-ups revealed complete resolution of the periapical lesion. This case underscores the importance of precise diagnosis, individualized treatment planning, and the application of advanced biomaterials in addressing complex presentations of dens invaginatus. The successful outcome emphasizes the efficacy of nonsurgical techniques in preserving immature teeth while restoring function and aesthetics.
牙内陷是一种发育异常，由釉质和牙本质向内折叠进入牙髓所致。奥勒斯IIIa型牙内陷因其复杂的解剖结构以及常与未成熟牙齿相关联，带来了重大挑战。本病例报告概述了一例患有IIIa型牙内陷的非活髓未成熟上颌中切牙的非手术治疗，该牙伴有慢性根尖脓肿且相关乳切牙有外伤史。治疗包括彻底的化学机械清创，随后使用富钙混合水泥进行生物性根管充填。定期随访显示根尖周病变完全消退。本病例强调了精确诊断、个性化治疗计划以及应用先进生物材料在处理牙内陷复杂表现方面的重要性。成功的治疗结果强调了非手术技术在保留未成熟牙齿同时恢复功能和美观方面的有效性。
