The coronal portion of both the maxillary and mandibular teeth of the required area can be-visualized on the film.


  • Detection of interproximal caries with respect to depth and relationship to pulp.
  • Detection in incipient interproximal caries
  • Observation of boundaries of the pulp chamber and the height of the pulp horns
  • Observation of primary resorption pattern
  • Observation of location and position of retained primary roots
  • Observation of relationship of opposing teeth

Bitewing radiograph can be taken with paper holders to which a tab is attached. The central x-ray beam is directed between the contact points of the teeth.

Similar to Bitewing radiograph, Occlusal radiographs are used in the evaluation of the entire maxillary arch or mandibular arch.
