Abstract
Diagnosis of dental caries is not the primary indication of Dental Cone Beam Computed Tomography (CBCT). However, when dental CBCT is available the dental caries may by an incidental finding. This chapter discusses the principles of CBCT and its use for detection of dental caries. Studies indicate that for interproximal caries CBCT has similar reliability as conventional intraoral bitewing radiographs; however, the increased enamel thickness encountered on occlusal surfaces may interfere with the reliability of dental CBCT during the diagnosis of occlusal caries. Its’ use for diagnosis of interproximal recurrent caries does not appear to be as predictable or as reliable as for the diagnosis of primary interproximal caries, although when available and used as an adjunct, dental CBCT can provide helpful diagnostic advice. It is expected that improvements i in the area of x-ray beam filters, dual energy sources and x-ray scatter reduction there will be greater accuracy for detection of caries.
