A dentigerous cyst is the most common developmental odontogenic cyst. It is a benign and asymptomatic intraosseous lesion that affects the bones of the maxillofacial complex, interfering with tooth eruption. This article reports the spontaneous eruption of a canine after marsupialization of an infected dentigerous cyst and extraction of the deciduous teeth. A radiograph showed a large cyst with a radiolucent area involving the mandibular left deciduous canine and first molar, and the permanent canine and first premolar. Although enucleation is the treatment of choice, marsupialization is the best option for large cysts involving an unerupted permanent tooth, as in this case. The patient was followed for 1 year, and eruption of the permanent canine and first premolar and gradual reduction of the radiolucent area were observed.
含牙囊肿是最常见的牙源性发育性囊肿。它是一种良性、无症状的颌骨内病变，会影响颌骨复合体的牙齿萌出。本文报道了经袋形术治疗感染性含牙囊肿和拔除乳牙后，犬牙的自发萌出。X 线片显示一个大的囊肿，有一个透光区域累及下颌左乳犬齿和第一磨牙以及恒犬齿和第一前磨牙。虽然肿瘤切除术是首选治疗方法，但对于涉及未萌出恒牙的大囊肿，如本例，经袋形术治疗是最佳选择。患者接受了 1 年的随访，观察到恒犬齿和第一前磨牙的萌出和透光区的逐渐缩小。
