Abstract

The dental profession has given increased attention to temporomandibular joint problems in recent years. Many orthodontists have shown professional concern by taking pretreatment lateral tomograms to assess developmental abnormalities, previous injury, pathology, and condylar position. The purpose of this study was to determine the consistency of orthodontists in evaluating lateral tomograms and panoramic films, particularly when used prior to treatment. Lateral tomograms and panoramic films of 60 single joints were evaluated by 4 orthodontists on two separate occasions. A questionnaire was completed for each radiograph observed and responses were compared for interobserver and intraobserver [aggreement]. Statistically, results showed little to no interobserver agreement, regardless of the type of radiograph used, though a trend of agreement did exist more predominantly with tomograms. There was a greater trend for intraobserver agreement than interobserver agreement on each question. Because of the apparent lack of interobserver agreement, the use of corrected tomograms prior to orthodontic treatment must be questioned.
