Abstract
Objective: Our objective was to verify the pathological decrease of the vertical dimension of occlusion in adult rodents is capable to produce morphologic alterations and/or morphometrics in their heads of the jaw and in case they happen in that area would prevail. Method: Twenty-four (24) mice were divided in 3 experimental groups and of each group they were separate three animals that served as control. Wear and tear occlusals and incisals were preceded until that if it reproduced a significant decrease of the vertical dimension of occlusion. The animals were sacrificed and they had their heads of the jaw, measured and analyzed morphometric and histologically, in the following intervals: 07 days for the 1st group, 14 days for the 2nd group and 28 days for the 3rd group. Result: The analysis through the stereoscopic magnifying glass demonstrated that there were significant form alterations and size in the heads of the jaws studied in comparison with the one of the animals control and that the area that more alterations suffered during the whole experimental period was the central area. The histological sheets showed great areas of bone reabsorption in images of degeneration of the head of the jaw in the 07 days experimental group; however, we identified areas of bone neoformation starting from the 14 days experimental group with strong presence of trabeculated bone in the 28 days experimental group. Conclusion: The pathological decrease of the vertical dimension of occlusion in mice provoked morphologic and morphometrics modifications in the studied areas of the heads of the jaw and after an initial period the happened adaptation if it completes with a remodelation process that, it takes to the re-establishment of the masticatory functions.
