Odontomas are the most common odontogenic hamartomas worldwide. Depending on the level of organisation of the tissues inside, these can be differentiated into compound type or complex type. As these are asymptomatic and do not cause any changes in the bone, they are often diagnosed during the routine dental examination. Complex odontomas are commonly found to occur in posterior mandible while compound odontomas are found in the anterior maxilla. A nine-year-old female child reported for a routine dental check-up, when a missing left permanent mandibular lateral incisor [32] was noticed. Further investigations revealed compound odontoma and unerupted 32, which is an unusual location. Early detection of these tumours is essential to avoid lengthy corrective treatments.
牙瘤是全球最常见的牙源性错构瘤。根据内部组织的结构程度，可将其分为复合型或复杂型。由于这些牙瘤无症状且不会引起骨骼的任何变化，它们常在常规牙科检查时被诊断出来。复杂型牙瘤常见于下颌骨后部，而复合型牙瘤则见于上颌骨前部。一名9岁女童前来进行常规牙科检查时，发现左下颌恒侧切牙[32]缺失。进一步检查发现了复合型牙瘤和未萌出的32号牙，这是一个不寻常的位置。早期发现这些肿瘤对于避免冗长的矫正治疗至关重要。
