ARTICLE HIGHLIGHTS
Research background
The process of learning, building, and improving radiographic diagnostic skills is a structured and rigorous undertaking that requires extensive human training. This should involve practicing radiologic technical skills, expanding scientific knowledge about diseases, and exposure to clinical environments.
Research motivation
Trabecular bone is highly visible, dominating images of the alveolar structure and adding complexity to human radiographic analysis. Nevertheless, most in vitro studies on the reliability of the radiographic method are carried out only on uncovered extracted teeth, which may increase the differences related to clinical study results. To date, no hard tissue simulation model can be manufactured in a simple and individualized way to mimic human bone for radiological training nor studies.
Research objectives
To investigate the potential of an alternative phantom to simulate the trabecular appearance of the human maxilla in conventional periapical radiographs.
Research methods
Half-maxillary phantoms built from gypsum-ground rice were exposed to X-rays, and the resulting images (experimental group) were compared to standardized radiographic images produced from dry human maxillary bone (control group) (n = 7). The images were blindly assessed according to strict criteria by three examiners for the usual trabecular aspects of the surrounding bone, and significant differences between groups and in assessment reliability were compared using Fisher’s exact and kappa tests (α = 0.05).
Research results
The differences in the trabecular aspects between groups were not statistically significant. In addition, interobserver agreement among observers was 0.43 and 0.51 for the control and experimental groups, respectively, whereas intraobserver agreement was 0.71 and 0.73, respectively.
Research conclusions
According to the preliminary results presented, the phantom constructed from dental gypsum and rice has the potential to simulate maxillary trabecular bone on laboratory periapical radiographs.
Research perspectives
The perspectives are to improve the technique using rice as well as the creation of techniques using other accessible materials.
