摘要： 目的:分析罕见下颌双侧第二磨牙远中牙龈组织对称萌出的外周性混合性牙瘤临床特点,结合文献探讨该病发生机制。方法:结合我院确诊的罕见下颌双侧第二磨牙远中牙龈组织对称萌出的外周性混合性牙瘤患者的临床资料,对比相关文献进行分析研究。结果:该患者没有外伤史、特殊感染史及遗传病史,在下颌双侧第二磨牙远中牙龈组织对称萌出外周性混合性牙瘤,瘤体无牙齿形状,表面光滑不规则,呈叶状实性钙化团块,与下颌双侧第二磨牙远中牙合面吻合。结论:青少年牙瘤的发现更多来自X线检查,非创伤、感染、遗传病史的个体也可能发生外周性混合性牙瘤,其萌出力可能借助于磨牙的萌出,对称发生较罕见,可能与牙胚发育早期相关基因表达或调控异常有关。

Abstract: Objective: Analyzed clinical and rare features of one patient with rare mandibular bilateral second molar distal gingival tissue symmetry eruption of Complex odontoma, and combined with literature to explore the pathogenesis of the disease. Methods: Analyzed clinical data of one patient who was accurate diagnosed with rare mandibular bilateral second molar distal gingival tissue symmetry eruption of Complex odontoma in our hospital and reviewed literature. Results: The patient had no history of trauma ,special infection and genetic disease , The patient with rare mandibular bilateral second molar distal gingival tissue symmetry eruption of Complex odontoma without teeth shape, unsmooth surface, with the presention of solid calcified mass, and matching mandibular bilateral distal to the second molar occlusal surface consistent. Conclusion: We found Adolescent dental odontoma by X-ray examination, non trauma, infection, genetic history of the individual may also occur in peripheral of mixed odontoma, the sprouting output may be by means of molar eruption, symmetry which is relatively rare may be related with gene expression and regulation of the abnormalities in the tooth germ early development.

Key words: Peripheral odontoma, Complex odontoma, Erupted
