摘要

正中贅齒常在乳牙齒列和早期混合齒列造成正中齒間缝、萌牙異常以及咬合不正，甚至引起骨頭破壞、牙根吸收、齒髓壞死或形成囊腫。本文主要提出兩個臨床案例，第一個案例是一對兩歲九個月雙胞胎姊妹，均在全身麻醉辅助下進行全口重建及手術移除兩個正中贅齒。第二個案例是一個八歲五個月男童，因左上正中乳門牙延遲脱落而求診。經臨床及X光檢查發現一水平正中贅齒，且已造成左上正中門牙移位。在接受手術移除正中贅齒，並經由矯正治療後獲得良好的美觀舆穩定的咬合。(Taiwan J Pediatr Dent 3(4):194-199,2003)

The presence of mesiodens may pose some clinical problems,especially in the stages of the primaryand early mixed dentitions.The most common clinical complications include central diastema,abnormal tooth eruption,and abnormal occlusal development.Mesiodens also contributes to bonedestruction,root resorption,pulpal pathosis,and/or the development of cysts.This article presents twocases of supernumerary teeth.The case 1 of twins had two inverted mesiodentes and rampant caries.Full mouth dental rehabilitation and surgical extraction of the mesiodentes were performed undergeneral anesthesia.The Case 2 had a retained #61 and an impacted mesiodens resulting indisplacement of #21.After surgical extraction of the mesiodens followed by orthodontic treatmentalignment,the esthetics and occlusion in the upper anterior region had been established.The timingfor surgical removal of the mesiodens is highly controversial.Early diagnosis and surgical interventionin the proper time may prevent the possible complications to the adjacent teeth and structures.(TaiwanJ Pediatr Dent 3(4):194-199,2003)
