RATIONALE
Mesiodens are supernumerary teeth located in the pre-maxilla between the two central incisors with a prevalence rate of 0.15-1.9%. An impacted mesiodens may cause delayed eruption of permanent incisors, ectopic eruption, pathological disturbances and malalignment of teeth.
PATIENT CONCERNS
The patient complained of missing upper front teeth associated with pain in the same region for two weeks.
DIAGNOSIS
Upon clinical and radiographic examination, it was diagnosed as triple impacted mesiodens with impacted permanent maxillary central incisors.
TREATMENT
The clinicians in the study approached the issue by surgical removal of the impacted mesiodens and orthodontic treatment for extrusion of the impacted permanent maxillary central incisors.
OUTCOMES
The patient was relieved of the pre-operative concerns and followed up regularly for the eruption of permanent maxillary central incisors.
TAKE-AWAY LESSONS: The authors advocate the importance of timely diagnosis and proper management of such rare pathologies.
原理
正中牙是位于上颌前部两颗中切牙之间的多生牙，患病率为0.15 - 1.9%。阻生正中牙可能导致恒牙中切牙萌出延迟、异位萌出、病理紊乱和牙齿排列不齐。
患者关注问题
患者主诉上前牙缺失并伴有同一区域疼痛两周。
诊断
经临床和影像学检查，诊断为三颗阻生正中牙伴上颌恒中切牙阻生。
治疗
该研究中的临床医生通过手术拔除阻生正中牙并对阻生的上颌恒中切牙进行正畸牵引来解决该问题。
结果
患者术前的担忧得到缓解，并定期随访观察上颌恒中切牙的萌出情况。
经验教训
作者强调了及时诊断和妥善处理此类罕见病症的重要性。
