FACTORS AFFECTING THE DIAGNOSTIC QUALITY OF BITEWING RADIOGRAPHS - A REVIEW

The bitewing radiograph (BWR) has been used in dental practice for ove r 90 years and is a widely used technique. This paper outlines the ide al 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 resu lt when radiographs are viewed. The consequences of these errors, (unn ecessary 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 i n line with recent recommendations.
