Bitewing

Bitewing radiographs are most frequently taken in the posterior regions of the mouth of the premolar and molar teeth for the detection of proximal caries and alveolar bone loss. For adult patients, the size 2 receptor is preferred. Bitewings can be oriented in either the horizontal or vertical plane with the receptor positioned parallel to the teeth crowns. Horizontal bitewings are the most common but vertical bitewings are taken particularly when moderate or greater alveolar bone loss is present.

Anterior bitewings can be taken to view bone levels in the anterior segments of the mouth as well. A size 1 receptor is used to capture incisor and lateral-canine bitewing views. The clinician can select traditional tabs or instrument holders to accomplish the bitewing survey. The vertical angulation used for tab bitewings ranges from +5^ο to +10^ο. The most common error associated with bitewing radiography is horizontal overlap which can render the image non-diagnostic.

Bitewing radiograph sizes

• Size 0-(22 x 35 mm) : For very small children
• Size 1-(24 x 40 mm) : For small children
• Size 2-(31 x 41 mm) : Routine adult size
• Size 3-(53 x 26 mm) : Longer film for adults.
