Efficacy of dental radiographic practices: options for image receptors, examination selection, and patient selection.

Many technical factors and treatment philosophies affect the way dental radiology is practiced. Some, like minimum tube filtration, are legislated. Others, like proper darkroom techniques, are universally acknowledged as essential. Still others, like the selection of an image receptor and the selection of the type of examination, are the subject of much discussion and debate. This article addresses some of the more controversial options and choices facing dental practitioners by reviewing the standard assessment techniques available to help make appropriate decisions, by summarizing and analyzing available data, and by offering recommendations for practice.

Temporomandibular joint arthrography following surgical treatment of internal derangements.

Arthrograms of the temporomandibular joint were obtained in 20 symptomatic joints that had previous reconstructive arthroplasty with disk repositioning because of internal derangements. Preoperative arthrograms were available for comparison in 18 joints. Symptoms resulting in a postoperative arthrogram included pain, limited ability to open the mouth, and clicking of the joints. Postoperative arthrographic findings included limited anterior translation of the condyle (90%), irregularity in outline of the intraarticular contrast agent (60%), a conical configuration of the posterior recess (25%), decreased size of the joint (28%), anterior displacement of the meniscus (25%), and perforated meniscus (15%). Many of these findings may have resulted from fibrosis and scarring, which may be a response to intraarticular bleeding. The mechanism by which the fibrosis causes the postsurgical arthrographic features is discussed.

The use of panoramic radiography in the evaluation of asymptomatic adult dental patients.

This article examines the efficacy of panoramic radiography alone and in combination with intraoral films as part of the "full-mouth" radiographic evaluation of asymptomatic dental patients in the diagnosis of dental caries and periodontal disease. Three full-mouth radiographic surveys--the panoramic alone, the panoramic plus posterior bitewing, and the periapical plus posterior bitewing--are compared. Two forms of measurement--comparative and incremental--were used to identify the radiographic survey with the highest single diagnostic yield when measured against the consensus standard. The findings show that the panoramic radiograph alone exhibits very low sensitivities to dental caries, ranging from 0.6% on anterior teeth to 25.6% on premolars. Even when posterior bitewing radiographs are added to the panoramic films, the sensitivities are significantly below those of the full-mouth periapical and bitewing survey. In contrast, the sensitivities of all three radiographic surveys in the diagnosis of periodontal disease are quite high, ranging from 87% to 96%, so that differences are not clinically significant. However, specificities tended to be low for periodontal disease and high for caries. Thus, for dental caries and (to a lesser extent) periodontal disease, the panoramic radiograph was inferior to the full-mouth intraoral series in its ability to correctly detect evidence of the disease.

A clinical comparison of X-ray films for detection of proximal surface caries.

This clinical study compares the diagnostic yield of Kodak Ektaspeed with the diagnostic yield of Kodak Ultraspeed using a split-mouth experimental design and proximal surface carious lesions as the test objects. Assuming that proximal surface carious lesions are distributed randomly in a given patient and in the population at large, then any difference in the diagnostic quality of either of the films should be disclosed as a difference in the frequency and distribution of lesions identified with either of the films. No statistical difference was observed, which suggests that the two films perform equally well for the diagnostic task of detecting proximal surface carious lesions. Considering that there is a 40% to 50% reduction in radiation exposure to the patient when the faster film is used, it appears that Kodak Ektaspeed should be the preferred film for the dental practitioner.

Dentigerous cyst with mural ameloblastoma.

A case of a 14-year-old black girl with a lesion that appeared to be a dentigerous cyst is presented. Radiographic appearance, findings of a bone scan and biopsy by aspiration are discussed. Histologic findings showed that the lesion was an ameloblastoma that is believed to have arisen from the dentigerous cyst wall.
