Abstract

OBJECTIVE

To determine the detection rate of mandibular condyle pseudocyst in both digital panoramic radiographs and film-based panoramic radiographs.

METHOD AND MATERIALS

All film-based and digital panoramic radiographs of patients treated at our institute during a 4-month period were analyzed by two experienced practitioners. Diagnosis of a condylar pseudocyst was based on the following criteria: appearance of cyst-like radiolucency, partially or completely circumscribed by radiopaque border, located at the anterior aspect of mandibular condyle.

RESULTS

825 radiographs (415 film-based, 410 digital) were included in the study. In 342 (41.5%) radiographs at least one condylar pseudocyst was observed, with no differences between radiograph type, 173 (42.2%) in digital and 169 (40.7%) in film-based radiographs (P = .36). Condylar pseudocyst detection rate was positively associated with older age (P < .001), whereas gender had no influence (P = .93).

CONCLUSION

An equally high detection rate of condylar pseudocyst was found in digital and film-based panoramic radiographs.

摘要

目的

确定数字化全景X线片和传统胶片全景X线片中下颌髁突假性囊肿的检出率。

方法与材料

由两名经验丰富的医生对我院在4个月期间治疗的患者的所有传统胶片和数字化全景X线片进行分析。髁突假性囊肿的诊断基于以下标准：囊肿样透射区表现，部分或完全被不透射线的边界所包绕，位于下颌髁突的前部。

结果

本研究共纳入825张X线片（415张传统胶片，410张数字化）。在342张（41.5%）X线片中观察到至少一个髁突假性囊肿，不同类型X线片之间无差异，数字化X线片中为173张（42.2%），传统胶片X线片中为169张（40.7%）（P = 0.36）。髁突假性囊肿的检出率与年龄较大呈正相关（P < 0.001），而与性别无关（P = 0.93）。
