ISSA, Joáo Paulo Mardegan et al. Comparative Bilateral Bone Density of the Mandible Angle. Int. J. Morphol. [online]. 2007, vol.25, n.2, pp. 337-340. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022007000200016.
The aim of this study was to assess a bilateral comparison of the mandible density in both sex young patients with computer densitometry. Fifty panoramic radiographs were obtained from young patients with ages between 18 and 23 years old (group A = 25 female and group B = 25 male) standardized, using the same X-Ray equipment (Siemens, lOKvp, 7mA), scanned with a 282.110 pixels resolution, and transferred later to a computer and using the SIDEXIS (Sirona, USA) program to analyze the bone densitometry performance. Bilateral sites were standardized with the objective to measure the bone density. Obtained data were registered and submitted to statistical analysis. The following means and standard deviations were obtained, in pixels, for the right and the left side, respectively: group A= 154.36±36.90 e 186.12+31.41, group B= 162.07±34.94 and 180.15+30.96. These values show statistical difference between different sides and groups (p<0.05), with a higher bone density on the left side in both groups, especially in group A
