Avaliação das dimensões transversas na maxila e mandíbula em pacientes na fase da dentição mista tratados com aparelho ortodôntico removível superior

Objeti vo: Avaliar os efeitos da expansão lenta na maxila e na mandíbula com o aparelho ortodônti co removível superior com torno de expansão simétrico e mediano, nas regiões oclusal, gengival e alveolar de pacientes jovens com atresia maxilar. Método: A amostra compreendeu 18 indivíduos leucodermas (11 meninas e 7 meninos; idade média: 8 anos e 10 meses no início do tratamento) que apresentavam atresia da maxila, acompanhadas ou não de mordida cruzada posterior uni ou bilateral na fase de denti ção mista. Todos os pacientes foram tratados com aparelho ortodônti co removível superior com torno de expansão simétrico e mediano, sendo o tempo médio de tratamento de 15,4 meses (± 7,6). Para avaliar a infl uência do tratamento nas mensurações dos pontos demarcados nas regiões oclusal, gengival e alveolar, foram uti lizados os modelos de gesso dos arcos superior e inferior (36 pares) obti dos em dois tempos: T1: início do tratamento e T2: ao fi nal do tratamento. Para cada paciente em ambos os tempos, foram mensuradas as distâncias transversas na região oclusal entre caninos decíduos, 1o molares decíduos ou 1o pré-molares permanentes e entre 1o molares permanentes, superiores e inferiores. Para verifi car se a movimentação ocorreu por inclinação ou por movimento de corpo, foram uti lizadas também medidas nas regiões gengival e alveolar. Os dados foram avaliados estati sti camente pelo teste “t student para amostras pareadas (5%). Resultados: Observou-se que em T2, todas as distâncias mensuradas para as regiões oclusal, gengival e alveolar apresentaram valores estati sti camente superiores às mesmas medidas em T1 (p<0,05). Conclusão: O aparelho ortodônti co removível superior é efeti vo nos casos de expansão lenta da maxila, agindo também indiretamente nas dimensões transversas do arco inferior.

Eletromiografia dos músculos temporal e masseter em crianças com mordida cruzada posterior direita

This study proposal was to evaluate the changes at a masticatory muscle temporalis and masseter, through a eletromyographic, at ponters of the right unilateral bite posterior, verifying the difference at the eletric activity between right and left sides. Twenty female volunteers, with ages between 7 and 8 (x = 7.4). The eletromyographics signals were collected in both sides in all volunteers in rest situations and in an usual isotonic mastication, right, left and bilateral and the maximun isometric constriction, which sinal was used to the eletric activity amplitude normalization. The results signed that the right masseter muscle presents an expressive statistic difference, if compared with the left masseter muscle during the left and right mastication, suggesting a right unilateral mastication. The muscle haven't gotten any expressive variance in this amplitude which remained to a proximate flat noticed in a right and habitual mastication, suggesting a right and one sided mastication during the left mastication occurs a raise of the eletric signal amplitude of the muscle left masseter. The right masseter muscle haven't gained any expressive variance, which remained in a proximate flat observed in an usual and right mastication, suggesting a muscular pattern hyperfunction next to the dental crossing.

Morphological characteristics of foramen of Vesalius and its relationship with clinical implications

The aim of this study was to evaluate the incidence as well morphometry of the foramen of Vesalius in human skulls and analyzing their clinical importance. Dry human skulls (n = 80) and with gender distinction were used (40 male and 40 female). The results demonstrates an total incidence of 40%, 13.75% skulls with the bilateral presence of the foramen, 26.25% skulls with the unilateral presence of the foramen, 31.25% skulls with foramen only of the right side, 22.50% skulls with foramen only of the left side, 25% masculine skulls with at least 1 foramen and 52.25% skulls with at least 1 foramen. The morphometry showed an average diameter of 1.457 ± 1.043 mm on the right and 1592 ± 0938 mm to the left. The average distance to the foramen ovale was 1.853 ± 0.303 mm on the right side and 2.464 ± 0.311 mm on the left. It can be concluded that a deepened anatomical study of the foramen of Vesalius collaborates not only for anatomical knowledge of this structure, but also in clinical situations involving this foramen.

Renal cell carcinoma with cutaneous metastasis in a dog

The present report describes the occurrence of skin metastasis in a dog with primary renal carcinoma. The clinical findings included progressive weight loss, inappetence, palpable abdominal mass and cutaneous nodules. The histopathological examination was carried out after unilateral nephrectomy and was confirmed by immunohistochemistry. The immunohistochemical and histopathological findings characterized this case as renal cell carcinoma with skin metastasis.

Prevalence of chewing side preference in the deciduous, mixed and permanent dentitions

Aim: This study evaluated the prevalence of the chewing side preference (CSP) in the deciduous, mixed and permanent dentitions. Materials and methods: Three-hundred subjects were divided in three groups (n = 100): Group 1 - children with deciduous dentition; group 2-children with mixed dentition; group 3 - subjects with permanent dentition. The CSP was determined using a direct method (visual observation) developed by McDonnell et al. (2004). Descriptive statistic was used to observe the prevalence of CSP. The Pearson's Chi-square was used to investigate signicant associations between gender, presence of CSP and preferred side (right/left). Results and conclusion: Eighty-seven percent of group 1 had a CSP. Eighty-two percent of group 2 had a CSP. Seventy-six percent of group 3 had a CSP. There was no statistically significant association between presence of CSP and gender in all groups. There was no statistically significant association between preferred side (right/left) and gender in all groups. Clinical significance: There is a higher prevalence of subjects in deciduous, mixed and permanent dentition that presented chewing side preference. The early diagnosis of the presence of chewing side preference can prevent the unilateral chewing pattern with prophylactic therapy applied to the first teeth (deciduous).
