A mesiodens appears most commonly as a supernumerary tooth impacted in the anterior maxilla. The purpose of this study is analyze mesiodens clinically.
Gender, crown form, direction of impaction, relation to permanent incisors, and chief complaints of patients with extracted mesiodens were analyzed.
Patients were analyzed for motivation to visit the hospital; 85.4% of the patients were referred from other hospitals. Mesiodens was more common in males than in females (3.7:1), and 70.1% of patients had only one mesiodens, while 29.6% had two mesiodenses. Of the mesiodenses, 61.4% were of the aconical form, and the most common direction was upward (62.4%), followed by the normal position (26.0%) and the horizontal position (11.6%). The mesiodenses caused orthodontic problems with the permanent incisors in 46.3% of cases. Mesiodens associated with dentigerous cyst was rarely observed in our patient group.
Mesiodens is more common in males than in females and often affects the permanent incisors. Thus, careful clinical and radiological evaluations of mesiodenses are important.
正中多生牙最常表现为上颌前部埋伏的额外牙。本研究的目的是对正中多生牙进行临床分析。
分析拔除正中多生牙患者的性别、牙冠形态、埋伏方向、与恒牙切牙的关系以及主要诉求。
分析患者就诊动机；85.4%的患者由其他医院转诊而来。正中多生牙在男性中比女性更常见（3.7:1），70.1%的患者只有一颗正中多生牙，而29.6%有两颗。在正中多生牙中，61.4%呈圆锥形，最常见的方向是向上（62.4%），其次是正常位置（26.0%）和水平位置（11.6%）。46.3%的病例中，正中多生牙导致恒牙切牙出现正畸问题。在我们的患者组中，很少观察到与含牙囊肿相关的正中多生牙。
正中多生牙在男性中比女性更常见，且常影响恒牙切牙。因此，对正中多生牙进行仔细的临床和影像学评估很重要。
