Panoramik Radyografilerde Sahte Renklendirme ile Osteoporozun Değerlendirilmesi

Abstract

Objective: The aim of this study is to evaluate osteoporosis based on mandibular cortical index (MCI) by performing pseudocoloring on panoramic radiographs. Material and Methods: This study was based on 300 panoramic radiographs that were obtained at the archive of Necmettin Erbakan University, Faculty of Dentistry, Dentomaxillofacial Radiology. In the panoramic radiographs evaluated within the scope of the study, C1, C2, and C3 scores were determined according to MCI. In the next step, the differences between pseudocoloring and scores were visually examined using the ImageJ program. Differences of pixel values corresponding to C1-C2-C3 scores were analyzed by the Kruskal-Wallis test. SPSS v21.0 (IBM Corp, Armonk, NY, USA) program was used to analyze of the data. Test results were evaluated according to a p<0.05 significance level. Results: Osteoporotic changes of C1-C2-C3 scores could not be visually distinguished on pseudocolored panoramic images. According to the numerical density values obtained in the histogram analysis, a significant difference was found between C1-C2-C3 scores (p<0.05). C3 has the highest density value, followed by C2 and C1, respectively (C3>C2>C1). Conclusion: Pseudocolored images obtained by using ImageJ program are not successful in visually distinguishing osteoporotic changes according to MCI on panoramic radiographs. Still, the differences between scores can be demonstrated numerically by histogram analysis. © 2023, Selcuk University. All rights reserved.
