Odontomas are the most common odontogenic tumors and are classified into compound and complex types. They result from a combination of odontogenic epithelium and ectomesenchyme. Complex odontomas frequently occur in the posterior mandible, whereas compound odontomas are more commonly found in the anterior region of the maxilla. Due to their small size and asymptomatic nature, odontomas are often diagnosed incidentally. Typically, odontomas are <3 cm in diameter; those exceeding this size are classified as giant odontomas and may present with extraoral swelling. This case report documents an unusual instance of a giant compound odontoma, containing 156 denticles, in a 15-year-old girl. Despite the odontoma's large size in the mandibular anterior region-an uncommon site for compound odontomas-the patient was completely asymptomatic and presented with only intermittent pain in the lower right back tooth region over the past month. The denticles were extracted, and intentional root canal treatment was performed on teeth 41, 42, 31, and 32 under general anesthesia.

牙瘤是最常见的牙源性肿瘤,分为组合型和复杂型。它们由牙源性上皮和外胚间充质组合而成。复杂牙瘤常发生于下颌骨后部,而组合牙瘤更常见于上颌骨前部。由于其体积小且无症状,牙瘤常为偶然发现。通常,牙瘤直径<3 cm;超过此大小的被归类为巨大牙瘤,可能出现口外肿胀。本病例报告记录了一名15岁女孩发生的罕见巨大组合牙瘤,含有156个牙小体。尽管该牙瘤在下颌前部区域体积巨大——组合牙瘤的罕见部位——但患者完全无症状,仅在过去一个月右下后牙区域有间歇性疼痛。取出牙小体,并在全身麻醉下对41、42、31和32号牙进行了根管治疗。
