| The aim of this study was to evaluate alterations in the masseter muscle of 30 male guinea-pigs submitted to occlusal alteration. The animals were divided into 2 equal groups, the control group (C) only submitted to surgical stress, and the occlusal altered group (T) submitted to teeth extraction. Each group was subdivided into 3 groups, with 5 animals, for the following studies: macroscopy and vessels distribution, light microscopy and histochemical analysis, with animals' perfusion 2 months after surgery. Data were submitted to statistical analysis. Macroscopically, an anteroposterior orientation of the muscular fibers was found and statistical difference between C and T groups in width (p<0.05). Microscopically, C and T groups showed polygonal... |
