【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鉭面吻合。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: to analyze the clinical features of the rare bilateral mandibular second molars with symmetrical exudation of gingival tissue, and to explore the mechanism of the disease. Methods: the clinical data of the rare bilateral mandibular second molars with symmetrical exudation of gingival tissue were analyzed and compared. Results: the patient had no history of trauma, history of special infection and hereditary disease. The gingival tissue of the mandibular second molar was symmetrically erupted from the gingival tissue. The tumor had no tooth shape, had a smooth and irregular surface, and presented as a leaflike solid calcified mass. The distal tantalum surface of bilateral mandibular second molar was anastomosed. Conclusion: the discovery of odontoma in adolescents may come from X-ray examination, noninvasive, infected, hereditary disease history individuals may also have peripheral mixed odontoma, its eruption force may rely on the eruption of molars, symmetric occurrence is rare. It may be related to abnormal gene expression or regulation in the early stage of tooth germ development.
