A mesiodens is the most frequent type of supernumerary tooth. They can be related to several complications, such as ectopic eruption and midline diastema. The aim of the present study was to assess the radiographic properties of mesiodens by analyzing the associated age, sex distribution, number of mesiodens per patient, shape, direction of eruption, and their association with complications.
The present study was performed using panoramic radiographs of 14 400 pediatric patients (4-14 years old) who visited the Department of Pediatric Dentistry at Gaziosmanpasa University for a variety of dental complaints from 2015 to 2018.
There were 82 mesiodens diagnosed in a total of 71 patients. Among the 82 mesiodens, 51 (62.1%) were conical in shape, which was the most commonly seen shape, followed by 14 supplemental (17.07%), and 12 (14.6%) tuberculate. Of the 82 mesiodens, 65 (79.2%) were aligned vertically, nine (10.9%) were inverted, and eight (9.7%) were horizontally placed. Clinical complications were observed in 76.8% of patients.
The management of mesiodens can be performed using three methods: (a) spontaneous eruption; (b) early intervention; and (c) delayed intervention. However, the management of mesiodens should be evaluated on an individual basis to determine the best treatment method. Mesiodens-associated complications should be addressed prior to the lateral incisors erupting.
正中多生牙是最常见的多生牙类型。它们可能与多种并发症有关，如异位萌出和中线间隙。本研究的目的是通过分析相关的年龄、性别分布、每位患者的正中多生牙数量、形状、萌出方向及其与并发症的关联，评估正中多生牙的影像学特征。
本研究使用了2015年至2018年期间因各种牙科问题前往加济奥斯曼帕夏大学儿童牙科就诊的14400名儿科患者（4 - 14岁）的全景X线片。
共71例患者诊断出82颗正中多生牙。在这82颗正中多生牙中，51颗（62.1%）呈圆锥形，这是最常见的形状，其次是14颗补充型（17.07%）和12颗结节型（14.6%）。在82颗正中多生牙中，65颗（79.2%）垂直排列，9颗（10.9%）倒置，8颗（9.7%）水平放置。76.8%的患者观察到临床并发症。
正中多生牙的处理可采用三种方法：（a）自然萌出；（b）早期干预；（c）延迟干预。然而，正中多生牙的处理应根据个体情况进行评估，以确定最佳治疗方法。与正中多生牙相关的并发症应在侧切牙萌出前处理。
