Comparative Bilateral Bone Density of the Mandible Angle International Journal of Morphology
Issa,Joáo Paulo Mardegan; Tiossi,Rodrigo; Catirse,Alma Blásida Concepción Elizaur Benitez; Monteiro,Solange Aparecida Caldeira; Watanabe,Plauto Christhopher Aranha.
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...
