: The aim of this study was to create an accessible, simple and reliable method for assessing the relative density of bone tissue in dentistry based on the analysis of digital panoramic radiographs. : Measurement of average gray values on orthopantomograms was carried out using ImageJ Version 1.54i software. To estimate the relative bone density, functions for selecting regions of interest (ROI), calculating the area of selection, and statistics of the selected area were used. Statistical characteristics of samples and testing of hypotheses using statistical criteria were performed using Microsoft Excel. : we found that when manually selecting the reference and comparison areas for areas without signs of pathological changes in bone tissue, the average standard deviation was 0.058, and the coefficient of variation was 0.055 ± 0.011%, which makes the choice of the jaw angle as a reference more preferable. The average relative bone density of the assessed defective areas to the jaw angle was 0.64 ± 0.11, and the average relative bone density of the areas without pathology to the jaw angle was 1.052 ± 0.058. : a research protocol was developed and justified using the ImageJ software package, which establishes a strict procedure for quantitative assessment of relative bone density based on the results of digital panoramic radiography. The proposed protocol can be used to monitor the condition of bone tissue after all types of dental treatment over time.
本研究的目的是基于数字全景X线片分析，创建一种用于评估牙科骨组织相对密度的可及、简单且可靠的方法。使用ImageJ 1.54i软件对曲面体层片上的平均灰度值进行测量。为了估计相对骨密度，使用了选择感兴趣区域（ROI）、计算选择区域面积以及所选区域统计的功能。使用Microsoft Excel进行样本的统计特征分析以及使用统计标准进行假设检验。我们发现，在手动选择骨组织无病理改变区域的参考区域和比较区域时，平均标准差为0.058，变异系数为0.055±0.011%，这使得选择下颌角作为参考更为可取。评估的缺损区域相对于下颌角的平均相对骨密度为0.64±0.11，无病理改变区域相对于下颌角的平均相对骨密度为1.052±0.058。使用ImageJ软件包制定并论证了一项研究方案，该方案基于数字全景X线摄影结果建立了相对骨密度定量评估的严格程序。所提出的方案可用于长期监测所有类型牙科治疗后骨组织的状况。
