Odontomas are the commonly occurring benign tumors of the jaw, which are odontogenic in origin. Lesion originates as the dental components are laid down in a disorganized manner, due to failure of normal morphodifferentiation. They are considered as hamartomatous developmental malformations rather than a true neoplasm. Mostly, these asymptomatic lesions are discovered as an incidental finding. Large odontomas may give rise to local disturbances, such as eruption delay of permanent teeth, asymmetric tooth eruption, malpositioning, displacement, resorption, or occasional devitalization of adjacent teeth. Odontomas may erupt into the mouth and tend to be associated with impacted teeth and other cystic lesions. The odontomas have a tendency to become symptomatic due to local infection such as sinusitis, infected adjacent tooth, and the exposure of tumor to oral environment. The aim of this paper is to elucidate the primary features and treatment of these lesions, depending on published data and individual witness.
牙瘤是颌骨常见的良性肿瘤，起源于牙源性。由于正常形态分化失败，病变起源于牙体组织的无序排列。它们被认为是错构瘤性发育畸形，而非真正的肿瘤。大多数情况下，这些无症状病变是偶然发现的。大型牙瘤可能引起局部干扰，如恒牙萌出延迟、牙齿不对称萌出、错位、移位、吸收，或偶尔导致相邻牙齿失活。牙瘤可能会萌出到口腔中，并往往与阻生牙和其他囊性病变相关。由于局部感染，如鼻窦炎、相邻牙齿感染以及肿瘤暴露于口腔环境，牙瘤有出现症状的倾向。本文旨在根据已发表的数据和个人经验阐明这些病变的主要特征和治疗方法。
