Abstract 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… More >
