The term mesiodens refers to a supernumerary tooth located between the maxillary central incisors. The aim of the study was to investigate the characteristics of mesiodens among children in Turkey. The study population involved 24 children who attended the Department of Pediatric Dentistry, Ege University for dental problems. The characteristics of mesiodens were obtained from clinical and radiographic examinations. Results showed that twenty-four patients had thirty-four mesiodens for an average of 1.42 mesiodens per person. Males were affected approximately 3 times more frequently in comparison with females. Forty-two percent of the patients had bilateral mesiodens. All of the mesiodens were conical in shape and 91% were in the downward position. The age and sex distribution, location, direction, eruption of mesiodens and effects on permanent maxillary incisors were also presented in this study. It could be concluded that, delayed, ectopic or asymmetric eruption of the central incisors should alert the clinician to the possibility of a mesiodens.
正中牙是指位于上颌中切牙之间的多生牙。本研究的目的是调查土耳其儿童正中牙的特征。研究对象为24名因牙齿问题到伊兹密尔埃杰大学儿童牙科就诊的儿童。通过临床和影像学检查获取正中牙的特征。结果显示,24例患者共有34颗正中牙,平均每人1.42颗。男性受影响的频率约为女性的3倍。42%的患者有双侧正中牙。所有正中牙均呈圆锥形,91%向下生长。本研究还介绍了正中牙的年龄和性别分布、位置、方向、萌出情况以及对恒牙上颌中切牙的影响。可以得出结论,中切牙萌出延迟、异位或不对称应提醒临床医生注意正中牙的可能性。
