Because of the horizontal angle of the X-ray beam, these radiographs also may reveal secondary caries below restorations that may escape recognition in the periapical views. Bitewing projections are also useful for evaluating the periodontal condition. They provide a good perspective of the alveolar bone crest, and changes in bone height can be assessed accurately through comparison with the adjacent teeth. In addition, because of the angle of projection directly through the interproximal spaces, the bitewing receptor is especially effective and useful for detecting calculus deposits\xa0in\xa0interproximal\xa0areas. (Because of its relatively low radiodensity, calculus is better visualized\xa0on\xa0images\xa0made\xa0with\xa0reduced\xa0exposure).\nRef: ORAL RADIOLOGY Principles\xa0and\xa0Interpretation, Stuart C.
