Analysis of Bone Quality on Panoramic Radiograph in Osteoporosis Research by Fractal Dimension

Abstract

Objective: To Assess the correlation between different quality analysis parameters of trabecular pattern in digital panoramic radiographies and relations with forearm bone mass density (BMD) performed by DXA. Methods: The study was developed using panoramic and peripheral bone densitometry dual energy X-ray absorptiometry (DXA) of 68 patients, 9 males and 59 females (19-73 years old). In the panoramic radiographs, evaluation of the trabecular bone morphology through assessment of fractal dimension (FD), connectivity (C) and total number of "bright" pixels (ET) was performed. In DXA, the exam determines the bone mineral density of the forearm to identify who has a high risk of osteoporosis. Statistics analyzed the relationship of these exams and the contribution of dental radiographs in detecting patients at risk for osteoporosis. Results: The average age of subjects was 43.85. In the analysis of trabecular pattern, a significant correlation between the FD, ET and C factors in level of 5% (Pearson correlation test) was found. Correlation tests showed no significant correlation between DF and BMD. Conclusions: The analysis showed correlations with each other, detecting alterations in the trabecular pattern. It cannot be related to BMD with FD but should be taken into account that examining the bone or trabecular alveolar process, when, for example, diagnostic analysis of pre-implant bone quality, is required.

Correlation between mandibular trabeculae bone density on panoramic radiograph and body mass index of men aged 5-35 years old

“…7 Some qualitative and quantitative indices, such as the mandibular cortical index, mandibular cortical thickness or mandibular panoramic index, use panoramic radiograph to assess the bone quality. 8 This study uses primary data in the form of panoramic radiographs. The population and sample of this study is male patients aged 5-35 years old who have done Dental Hospital Padjajaran University Panoramic Radiography at Dental Radiology Installation between January and February 2018.…”

Automatic detection of pneumonia in chest X-ray images using textural features

“…Although these structures cannot be considered true geometric fractals, since their property of self-similarity does not extend to infinity, it is possible to define it, to a certain degree, where the concept of repetition is limited to a biologically relevant spatial scale window [ 41 ]. While the use of fractal dimension for x-ray image analysis has focused on the study of bone tissue [ 42 , 43 ] examples of its use can be found in a wide variety of clinical settings, as brain structures analysis [ 44 ] or vascular patterns studies [ 45 ]. However, its use in the pneumonia detection in X-ray has been so far limited [ 46 ].…”

Diagnostic Application of Fractal Dimension Analysis of Bone Invasion in Oral Malignancy—A Preliminary Retrospective Study

“…Panoramic radiography is highlighted in this context because it is frequently taken in the dental office; it is rapid and low cost and uses low dose of radiation. 2 With recent advances in digital technology, image analysis has become an essential part of several research areas from nanotechnology to neuroscience. 3 FD analysis using digital orthopantomograms (OPGs) is a novel method, which can be used for early diagnosis of bony invasion by oral cancer.…”
