Bitewing Radiograph
An intraoral X-ray that shows the crowns of both upper and lower posterior teeth and the crest of the alveolar bone on a single image.
Full Definition
A bitewing radiograph is an intraoral dental X-ray taken with the patient biting down on a tab or wing attached to the film or sensor, positioning it parallel to the crowns of the posterior teeth. It simultaneously displays the crowns of both maxillary and mandibular teeth and is primarily used to detect interproximal caries and assess alveolar bone levels. Unlike periapical radiographs, bitewings do not show the root apices. Editors should note that 'bitewing' is written as a single closed compound, not hyphenated or two words. Horizontal and vertical bitewings differ in their orientation and diagnostic application.
Usage
Usage note: 'Bitewing' is always one word, never hyphenated. Distinguish from periapical radiographs, which capture root apices.
