The three-function XCP-ORA dental X-ray positioning device consists of five different parts, three parts of which together make a specific assemblage for taking anterior, posterior or
bitewing radiographs, respectively.
Dentists routinely rely on
bitewing radiographs to help diagnose interproximal caries.
Table 3 shows the error that necessitated each retake for PSP plates and direct sensors when taking
bitewing radiographs. The main cause of bitewing retakes, for both direct sensors (26.8%) and PSP (15.4%), was an error in image receptor placement.
In vitro performance of a pen-type laser fluorescence device and
bitewing radiographs for approximal caries detection in permanent and primary teeth.
Although the prevalence rates have been reported using
bitewing radiographs and OPTs, PEIR can be detected using either radiograph.
Unfortunately, the devices can be confusing to assemble because each device consists of three pieces that can be assembled in multiple ways, and there are three types of such devices for anterior, posterior and
bitewing radiographs (in addition to a fourth accessory device for taking endodontic radiographs).

For example, dental radiographs are useful in detecting larger, advanced and possibly cavitated dental caries, but limited image resolution and poor radiographic contrast of early carious lesions reduces radiographs insensitive for detecting early stage dental caries.6 In the last decade, several new caries detection methodologies have emerged.8 Many of these new developments are
bitewing radiographs, dyes, fiber-optic light transillumination, and quantitative light (or laser) induced fluorescence.9
