| Considering the biomechanical aspects, many facts need to be understood on the mandible, to know which effects unilateral occlusal changes may cause on the stomatognathic system. The aim of this study was to analyze the malocclusion by unilateral teeth extraction on the mandible morphology in gerbil. We used 10 gerbils Meriones unguiculatus, young male, weighing around 50-60g, divided into two groups (n=5), an experimental group and control, which evaluated the two hemi-mandibles, with a total of 20 samples which were measured by digital pachymeter. The measures were taken: (1) length and (2) width of the mandible condyle and (3) body height in the region of mandibular 1st molar. Data from these measurements were analyzed using ANOVA and Mann-Whitney test.... |

| The aim of this article is to show the clinical and histochemical alterations of the first periodontal ligament, on the right side, after upper molars teeth extraction on the left side in gerbils. After two months, the periodontal ligaments were removed and processed for histochemical analysis. The data showed that TRAP reaction was able to evidence the osteoclastic activity in the hyperfunction hemimandible, right side, explaining the functional changes in the periodontal ligament after teeth extraction, and a little gingival recession and radicular exposure of teeth without function was observed at inferior molars of the left side |
