摘要/Abstract

摘要： 目的:分析与阻生牙有关的牙源性角化囊肿的临床和影像学特点。方法:对235例牙源性角化囊肿中36例与阻生牙有关的临床、影像学资料进行回顾分析。结果:在与阻生牙有关的牙源性角化囊肿病例中,男女比例为1.77∶1,下颌磨牙-下颌支部26例,占72.22%;19例（52.8%）在20~30岁就诊。单房型27例（75%）,多房型9例（25%）;牙冠位于囊内13例（36.11%）,整个牙位于病变内15例（41.67%),而阻生牙位于病变一侧8例（22.22%）。结论:与阻生牙有关的牙源性角化囊肿的一个主要影像学特点是,整个牙被病变包绕或位于囊肿一侧,而表现为冠周密度减低影像者较少。

Abstract: PURPOSE: To analyse the imaging features of odontogenic keratocysts (OKCs) associated with an impacted tooth. METHODS: Clinical and radiological data of 235 cases with OKCs were respectively investigated, with emphasis on imaging features of 36 OKCs, which were associated with an unerupted tooth. RESULTS: In 36 cases of OKCs associated with an impacted tooth, the ratio of male to female was 1.77:1, and molar-ramus was involved in 26 cases (72.22%). OKCs in association with an unerupted tooth occurred mostly in patients ranging from 20 to 30 years (19 cases, 52.8%). There were 27 cases (75%) of unilocular and 9 cases (25%) multilocualr radiolucency. Thirteen cases (36.11%) were related to the crown of the impacted teeth, and the unerupted teeth also were impacted as a result of malposition in which the entire teeth appeared to be enveloped by cysts (15 cases, 41.67%), or adjacent to cyst wall (8 cases, 22.22%). CONCLUSIONS: Radiographically, one of the most imaging features of OKCs in association with an unerupted tooth is that its entire tooth appears to be enveloped by cyst or adjacent to cyst, while pericoronal radiolucencies surrounding an impacted tooth are rarely seen.
