The use of radiographic techniques in the diagnosis and management of periodontal diseases.

Radiographs continue to play an important role in the diagnosis and management of periodontal disease although opinions as to the most appropriate form of assessment vary. It is important to recognize the limitations of each technique in terms of resolution, repeatability and accuracy so that radiographs can be correctly interpreted to the benefit of the patient. The value of intra-oral and panoramic radiography is reviewed, with particular reference to articles published over the past five years, followed by a consideration of developing computer-aided techniques which may, in time, prove of value to the dental practitioner in the diagnosis and management of periodontal disease.
