Odontomas are benign tumors of odontogenic origin characterized by their slow growth. They consist of enamel, dentine, cementum and pulpal tissue and constitute 22% of all odontogenic tumors. Two types of odontoma are recognized: compound and complex. The first is approximately twice as common as complex odontomas. The purpose of this study is to value the prevalence of this kind of tumors in the ambulatory-surgical gambit and their clinical symptoms. We want to emphasize the exceptional spontaneous eruption of this tumors and we report a case of erupted complex odontoma. We made the revision of the cases of diagnosed odontomas between 1983 and 2001 in the Clínica Ntra. Sra. del Remei, in the Centro Médico Teknon and the Master de Cirugía e Implantología Bucal of the Odontologic Clínic (Barcelona University). We analyzed their prevalence, distribution in gender, age of the patients, anatomic location, adjacent structures affectation, symptoms, histologic classification and treatment. 52.4% of the cases were diagnosed in females. 37.7% of the tumors were complex odontomas and 62.3% were diagnosed as compound odontomas. 55.7% of all cases were in the maxilla and 44.3% in the mandible. The anterior portion of maxilla was the most common location (54% of cases). Only a case (1.6%) was erupted, in the molars area of the maxilla.
牙瘤是牙源性良性肿瘤，其特点是生长缓慢。它们由釉质、牙本质、牙骨质和牙髓组织组成，占所有牙源性肿瘤的22%。牙瘤可分为两种类型：组合性和复杂性。前者的发病率约为复杂性牙瘤的两倍。本研究的目的是评估这类肿瘤在门诊手术中的患病率及其临床症状。我们想强调这类肿瘤罕见的自发萌出情况，并报告一例已萌出的复杂性牙瘤病例。我们回顾了1983年至2001年间在Ntra. Sra. del Remei诊所、Teknon医学中心以及巴塞罗那大学牙科学院口腔外科与种植硕士项目中诊断出的牙瘤病例。我们分析了它们的患病率、性别分布、患者年龄、解剖位置、对相邻结构的影响、症状、组织学分类和治疗情况。52.4%的病例在女性中被诊断出。37.7%的肿瘤为复杂性牙瘤，62.3%被诊断为组合性牙瘤。所有病例中55.7%位于上颌骨，44.3%位于下颌骨。上颌骨前部是最常见的位置（占病例的54%）。仅1例（1.6%）已萌出，位于上颌磨牙区。
