Effect of display monitor devices on intra-oral radiographic caries diagnosis

Abstract

Appropriate monitors are needed for radiographic diagnosis on monitor screens.

Performance of 5 different displays in the detection of artificial incipient and recurrent caries-like lesions

“…While we also did not standardize any of the non-auto DICOM calibrating monitors, we found no significant difference between monitors. The reason given by Araki et al 3 for the difference was related to the novelty of usage of the tablet display by the observers. While this may be a valid explanation, it was not confirmed in our study.…”

“…One study showed a statistically significant difference between monitors for enamel caries detection. 3 They also found that after the caries was into the dentin layer the statistical significance found within the enamel observation was no longer observed. 3 This could be interpreted to mean that the more advanced disease of dentinal caries will be accurately displayed regardless of monitor type.…”

“…2 Additionally, a recent study showed a PC tablet to have significantly lower accuracy when detecting enamel caries. 3 In contrast, tablet computers have reliably shown anatomical landmarks in panoramic and lateral cephalometric radiographs. 4 While most monitors are liquid crystal displays (LCD), newer monitor options include light emitting diode (LED)backlight displays.…”

“…A couple examples are the TG18-QC patterns and the Society of Motion Picture and Television Engineers (SMPTE) calibration pattern. A poor display quality may lead to a missed diagnosis and/or misinterpretation of overall disease state or progression 3 , which may result in inappropriate or no treatment for a particular condition.…”

“…There have also been a few studies in the dental literature, which have compared the effects of using medical displays, off-the-shelf consumer monitors and/or computer tablets on the diagnosis of dental diseases like caries. [3][4][5] However there was not a study found that included secondary caries as a diagnostic variable.…”
