Various radiographic techniques are applied for diagnosing mandibular fractures. Standard radiographs used in the hospital to diagnose mandibular fractures have included lateral oblique, posteroanterior, and fronto-occipital (Towne) mandibular projections. If positive, the panoramic radiograph can be used as the sole radiograph. A case is reported of a unilateral fracture of the mandibular angle, which became evident about one month after extraction of the mandibular third molars. Neither the lateral oblique nor the panoramic projection revealed the fracture; however, periapical films showed the fracture through the extraction site.
多种放射学技术被应用于诊断下颌骨骨折。医院用于诊断下颌骨骨折的标准X光片包括下颌骨侧斜位、后前位和额枕位（汤氏位）投照。如果结果呈阳性，全景X光片可作为唯一的X光片使用。本文报告了一例下颌角单侧骨折病例，该骨折在拔除下颌第三磨牙约一个月后才显现出来。下颌骨侧斜位片和全景片均未显示骨折；然而，根尖片通过拔牙部位显示出了骨折。
