A comparison between bitewing radiographs taken with rectangular and circular collimators in UK military dental practices: a retrospective study

摘要

ObjectivesThe aim of this study was to determine any increase in the incidence of cone cut errors that adversely affected diagnostic yield resulting in more retakes using rectangular collimation with film holders in bitewing radiography. Comparisons were also made with other positioning errors that occurred when bitewings were taken with circular collimation, with and without film holders.
