'Mesiodens' are the supernumerary teeth present in the midline of the maxilla between the two central incisors. These mesiodens are the most common supernumerary teeth and are usually responsible for eruption disturbance or delay of the maxillary anterior permanent teeth. The present study seeks to investigate the prevalence of mesiodens among school going children in Indore City, India.
The study was a retrospective collection of data to evaluate the prevalence of mesiodens among 3896 children, whose ages ranged between six and seventeen years.
The results showed that males were affected approximately 1.2 times as frequently as females; 3.18% of the total screened population had mesiodens and among the affected population 4.03% had two or more mesiodens. Most of the mesiodens were conical in shape. The age, sex distribution, number of mesiodens per patient, shape, and direction of the eruption are presented in this study.
The present study gives an insight into the prevalence of mesiodens among school going children of Indore city. A coincidental finding in our study has been the high risk of trauma associated with the occurence of mesiodens. This finding makes it mandatory to include mesiodens as a risk factor in traumatic dental injuries. Early diagnosis and management of these otherwise considered mild factors must be made mandatory in pediatric dentistry.
“正中牙”是位于上颌骨中线、两颗中切牙之间的多生牙。这些正中牙是最常见的多生牙，通常会导致上颌前部恒牙萌出障碍或延迟。本研究旨在调查印度印多尔市学龄儿童正中牙的患病率。
本研究是一项回顾性数据收集研究，旨在评估3896名年龄在6至17岁之间儿童的正中牙患病率。
结果显示，男性受影响的频率约为女性的1.2倍；在所有筛查人群中，3.18%患有正中牙，在受影响人群中，4.03%有两颗或更多颗正中牙。大多数正中牙呈圆锥形。本研究呈现了年龄、性别分布、每位患者的正中牙数量、形状以及萌出方向。
本研究深入了解了印多尔市学龄儿童正中牙的患病率。我们研究中的一个意外发现是正中牙的出现与创伤风险高相关。这一发现使得必须将正中牙作为创伤性牙损伤的一个风险因素。在儿童牙科中，必须对这些原本被认为是轻微因素的情况进行早期诊断和管理。
