Abstract
Introduction Intraoral film processing can be performed manually using chambers manufactured from opaque material to prevent light from entering and consequently blurring images. The aim of this study was to evaluate whether portable darkrooms used in offices, clinics and educational institutions prevent the entry of light during the processing of intraoral films. Methods To this end, tests were carried out and images were analyzed by measuring the optical base-plus-fog densities (ODs) upon imaging. Results Review of the OD measurements revealed that in 70.7% of the evaluated manual portable revelation cameras, the base-plus-veil density of intraoral films was not in accord with that of the protocol reference. Discussion The results of this work can be used to identify chambers that are commonly exposed to light from fluorescent lamps and solar lighting.
