Supernumerary teeth refers to an excessive number of teeth and are relatively common in the oral cavity. The supernumerary tooth located in the midline of the maxilla between the central incisors is referred to as "mesiodens". The present study emphasizes the importance of multidisciplinary management and long-term follow-up of patients with mesiodens.
This study investigates the characteristics of mesiodens among children in patients reported to department of pediatric and preventive dentistry in an institution in the state of Tamil Nadu, India.
The study population consisted of 55 children below 14 years. The characteristics of mesiodens were obtained from radiographs and clinical examination. And all these were confirmed as mesiodens by surgical intervention.
Results showed that males were affected approximately 2 times as frequently as females. Predominant shape of the mesiodens was conical (79.7%). 27 (49.09%) of 55 patients had multiple mesiodens. 25 (45.45%) of 55 patients required orthodontic correction after surgery.
Mesiodens can cause many complications. So routine radiographic examination of all pediatric patients is advised. And when identified, they should be extracted as early as possible in children and adolescents in order to avoid possible complications.
多生牙是指牙齿数量过多，在口腔中相对常见。位于上颌中切牙之间中线处的多生牙被称为“正中牙”。本研究强调了对正中牙患者进行多学科管理和长期随访的重要性。
本研究调查了印度泰米尔纳德邦一家机构的儿童牙科与预防牙科部门报告的患者中儿童正中牙的特征。
研究人群包括55名14岁以下的儿童。通过X光片和临床检查获取正中牙的特征。所有这些均通过手术干预确认为正中牙。
结果显示，男性受影响的频率约为女性的2倍。正中牙的主要形状为圆锥形（79.7%）。55名患者中有27名（49.09%）有多颗正中牙。55名患者中有25名（45.45%）在手术后需要正畸矫正。
正中牙可引起许多并发症。因此，建议对所有儿科患者进行常规X光检查。一旦发现，应在儿童和青少年中尽早拔除，以避免可能的并发症。
