The Treatment of a 7 Year Boy with Large Dentigerous Cyst: Case Report
七歲男童含齒囊腫的治療－病例報告
摘要
大多數兒童頜骨腫脹常導因為齒源性的囊腫或是腫癌。其中大部份的齒源性囊腫為根尖囊腫及含齒囊腫。初期的時候，症狀常常極為輕微而難以被患者自己發現。隨著時間的經過，囊腫逐漸增大並侵犯到齒槽骨。患者常因牙齒萌發上的障礙或例行性的檢查，經過放射線照射檢查後，才發現到有囊腫的存在。若囊腫大小不大，可以外科手術予以切除。但有時囊腫較大將會導致相鄰牙的阻生及移位。這個病患為七歲六個月男童伴隨右下第二小臼齒阻生及含齒囊腫的腫大，經過適當的治療，我們將阻生的右下第二小臼齒在不施予主動矯正治療的情況下導引至正確的萌發位置。

The common causes which lead children to jaw swellings are cysts and tumors of odontogenic origin. The common odontogenic cysts may be radicular and dentigerous cyst. In the initial stage, it may be asymptomatic. As time goes by, the lesion mat expand and invade the alveolar bone. Dentigerous cysts are usually found on routine radiographic examination or when films are taken to determine the reason for failure of a tooth to erupt. If the cyst is small, it is easy to treat surgically. However, dentigerous cyst may be large and difficult to treat. The impacted tooth may be displaced by cyst pressure for a considerable distance. It increase the difficulty to let the impacted tooth erupt into the proper occlusion. Today we want to present a case with large dentigerous cyst with impacted mandibular second premolar. The case is a 7 years and 6 months old boy. After enucleation and decompression of the cyst, we guide the impacted mandibular second premolar into proper position without active orthodontic treatment.
