Determination of Bone Quality on Panoramic Radiograph in Osteoporosis Research by Fractal Dimension | Chapter 4 | Novel Research Aspects in Mathematical and Computer Science Vol. 8

 The purpose of this chapter is to establish a link between the forearm bone mass density (BMD) as determined by DXA and various quality analysis variables of the trabecular pattern in digital panoramic radiographies. 68 people were studied using dual energy X-ray absorptiometry (DXA), of which 9 were men and 59 were women (19-73 years old). The fractal dimension (FD), connectivity (C), and overall number of "bright" pixels were used to assess the trabecular bone morphology in the panoramic radiography (ET). To identify those most at risk for osteoporosis, the bone mineral density of the forearm is measured during the DXA test. The statistical relationship between DXA tests and the ability of FD, C, and ET dental radiographs to identify individuals at risk for osteoporosis was investigated. The subjects were, on average, 43.85 years old. In analysing the trabecular pattern, a 5% level significant association between the FD, ET, and C variables was found (Pearson correlation test). The results of correlation tests showed no connection between DF and BMD. In order to discover changes in the trabecular pattern, the study identified correlations between the variables. It should be taken into account that analysing the bone or trabecular alveolar process is not associated to BMD with FD when, for example, a diagnostic study of pre-implant bone quality is necessary.
