[Trends in dental radiology--a review of the literature].
Dental radiology is experiencing a marked improvement in equipment and its comfort of use. The production of intensifying screens with calcium tungstate stratification causes considerable diminution of radiation damage although at the price of changes in the structure of the picture. Xeroradiography is stagnating after promising beginnings. The protection of the patient against radiation has improved and recent work shows that in the dental field, more care must be given to preserve the lens of the eye from radiation hazard. Pantomography as a diagnostic means is progressing although it has not been able to substitute for the conventional radiography. TMJ radiography does not make exception in the same sense, so the knowledge of the correct use of special cranial radiographs remains.
