摘要/Abstract

摘要： 目的：报道1例双侧上颌第四磨牙病例，探讨多生第四磨牙的发生和治疗方案。方法：收集1例双侧上颌第四磨牙患者的病历资料，记录患者的各项信息，结合文献复习，回顾性分析双侧上颌第四磨牙患者的临床资料和并发症及治疗方案。结果：患者因左上颌后牙区间歇性隐痛数月，加重5 d就诊，专科检查未见可引起主诉症状的异常表现。全口曲面断层片可见双侧上颌区4颗磨牙，第四磨牙位于第三磨牙远中，完全阻生，牙冠较小，牙根较短，压迫使邻牙牙根吸收。拔出18、28和29，患者左上颌后牙区疼痛消失。结论：多生第四磨牙是一种较少见的牙齿发育异常现象，但其存在较多可能的并发症，因此早期诊断及治疗至关重要。

Abstract: Objective:To report one case of bilateral maxillary fourth molars, and to explore the occurrence and treatment method of additional fourth molar. Methods: The case materials of one patient with bilateral maxillary four molars were collected, and the information was record. Combined with reviewing the relevant literatures, the clinical data, complication and treatment of one patient with bilateral maxillary fourth molars were retrospectively analyzed. Results: The patient was diagnosed due to left maxillary posterior teeth area intermittent pain for several months and the increased pain for 5 d; at the same time,there was no abnormal appearance inducing the symptoms detected by speciality check-up. The pantomography showed the four molars in bilateral maxillary, and the fourth molars impacted the third molar root's absorption. The fourth molar crown was smaller and the root was shorter. The 18,28,29 teeth were removed,and the left maxillary posterior teeth area intermittent pain disppeared. Conclusion: The occurrence of additional fourth molar is a relatively rare demal dysplasia. However,there are some complications following with the fourth molar. Early diagnosis and treatment are essential.
