Periapical radiographs as an aid in diagnosing fractures of the mandibular angle
1Department of Oral Diagnosis/Radiology/Medicine, Louisiana State University School of Dentistry, New Orleans 70119, USA.
Abstract:
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.
