Determination of Optimal Angles for Intraoral Occlusal Views for the Radiographic Imaging of Dental Structures in the Cynomolgus Monkey (Macaca fascicularis).

Highly detailed dental radiographs aid in obtaining an accurate diagnosis of common dental abnormalities. This paper compares three oblique angle intraoral occlusal views for the evaluation of the teeth of the maxillary and mandibular arcade of cynomolgus monkeys. The best views for isolating tooth structures of the canine, premolar, and molar teeth of the mandibular and maxillary arcades were obtained by directing the primary beam 608 relative to the hard palate in the transverse plane. The dorsoventral view allowed superior visualization of the maxillary incisor teeth, whereas the ventrodorsal view was best for evaluating the mandibular incisor teeth. Survey radiographs obtained by using these views, coupled with thorough dental examination, would aid the accurate diagnosis of dental abnormalities in cynomolgus monkeys.
