Factors affecting the diagnostic quality of bitewing radiographs: a review.
The bitewing radiograph (BWR) has been used in dental practice for over 90 years and is a widely used technique. This paper outlines the ideal technique for producing reproducible BWR of good diagnostic quality. In particular, it reviews the technical errors that may occur while exposing and processing BWR and the psychological errors that may result when radiographs are viewed. The consequences of these errors, (unnecessary patient exposure to radiation, poor diagnosis and potentially inappropriate treatment) are outlined in detail. Steps to improve the quality of BWR and decrease patient exposure to radiation are given in line with recent recommendations.
