The initial clinical and radiological examination by this author included a standard periapical and an
occlusal film (see Figures 2,3, and 4).
Whereas an
occlusal film together with a panoramic view are routinely used for vertical parallax.
(3) The classic
occlusal film can reliably show ductal sialoliths, but small and intraglandular stones may be missed.
Although various radiographic exposures including
occlusal films, panoramic views, and lateral cephalograms can help in evaluating the position of the canines, in most cases periapical films are uniquely reliable for that purpose.5

Occlusal films are cross-sectional views of the dental arches and the incisal edges of the teeth.
Occlusal films also are useful in patients who cannot open their mouths wide enough to accommodate a periapical film, such as patients with trauma or temporomandibular joint (TMJ) conditions, as well as small pediatric patients.
Posterior mandibular occlusal films are exposed in the same manner, but with the film positioned over the area of interest.
Periapical and occlusal films are used to image specific areas of interest when a highly detailed image is desired.
