ABSTRACT

O objetivo deste trabalho foi verificar a efetividade na descontaminação de cones de guta-percha e de resilon com os seguintes grupos: hipoclorito de sódio 5,25% durante 1 minuto; hipoclorito de sódio 2,5% durante 1 minuto; clorexidina 2% durante 1 minuto; glicerina fenicada durante 24 horas. Os agentes apresentaram-se eficazes, sem diferença estatística significativa, embora a clorexidina a 2% tenha apresentado um percentual de 20% de amostras positivas tanto na guta-percha como no resilon, o que pode ser considerado relevante clinicamente. Concluiu-se que o hipoclorito de sódio e a glicerina fenicada podem ser indicados para a descontaminação de ambos os tipos de cone, nas duas concentrações testadas.


The aim of this study was to assess the effectiveness in decontamination of gutta-percha and Resilon with the following groups: 5.25% sodium hypochlorite for 1 minute; 2.5% sodium hypochlorite for 1 minute, 2% chlorhexidine during 1 minute; glycerin fenicada for 24 hours. The agents had been effective, not statistically significant, although the 2% chlorhexidine presented a higher percentage of 20% of positive samples in both the gutta-percha and Resilon in what can be considered clinically relevant. It was concluded that sodium hypochlorite and glycerin fenicada may be indicated for the decontamination of both types of cone, at the concentrations tested.

ABSTRACT

A clinical study of Brazilian patients with neurofibromatosis type 1 (NF1) was performed in a multidisciplinary Neurofibromatosis Program called CEPAN (Center of Research and Service in Neurofibromatosis). Among 55 patients (60 percent females, 40 percent males) who met the NIH criteria for the diagnosis of NF1, 98 percent had more than six café-au-lait patches, 94.5 percent had axillary freckling, 45 percent had inguinal freckling, and 87.5 percent had Lisch nodules. Cutaneous neurofibromas were observed in 96 percent, and 40 percent presented plexiform neurofibromas. A positive family history of NF1 was found in 60 percent, and mental retardation occurred in 35 percent. Some degree of scoliosis was noted in 49 percent, 51 percent had macrocephaly, 40 percent had short stature, 76 percent had learning difficulties, and 2 percent had optic gliomas. Unexpectedly high frequencies of plexiform neurofibromas, mental retardation, learning difficulties, and scoliosis were observed, probably reflecting the detailed clinical analysis methods adopted by the Neurofibromatosis Program. These same patients were screened for mutations in the GAP-related domain/GRD (exons 20-27a) by single-strand conformation polymorphism. Four different mutations (Q1189X, 3525-3526delAA, E1356G, c.4111-1G>A) and four polymorphisms (c.3315-27G>A, V1146I, V1317A, c.4514+11C>G) were identified. These data were recently published.

ABSTRACT

O objetivo deste estudo é descrever uma técnica de instrumentaçäo de canais radiculares, baseada em princípios renovados, que utiliza movimentos contínuos de rotaçäo alternada. Esta técnica apresenta uma série de vantagens, como: a) permite a limpeza e a manutençäo do forame apical em sua posiçäo original; b) facilidade de execuçäo; c) reduçäo do tempo de trabalho e da fadiga do operador; d) facilidade de acesso ao terço apical por parte de soluçöes irrigadoras e dos instrumentos utilizados; e) controle máximo do preparo apical, permitindo uma maior ampliaçäo do terço apical do canal menor risco acidentes, como extrusäo de detritos e confecçäo de desvios ou transportes

ABSTRACT

Neste estudo foram incluidos 148 doentes, sendo 65 com pitiriase versicolor e 83 com dermatofitoses, submetidos a tratamento com ketoconazole por via oral. A dose diaria foi de 200mg (um comprimido) durante duas a quatro semanas para os casos de pitiriase versicolor e de quatro a oito semanas para os de dermatofitoses. O tratamento determinou, nos doentes de pitiriase versicolor, cura clinica e micologica em 50 (78,1%), apenas cura clinica em dois (3,1%) e cura micologica em um (1,6%). Nos doentes com dermatofitoses, em 69 (84,1%) houve cura clinica e micologica, quatro (4,9%) apresentaram cura micologica e cinco (6,1%) tiveram apenas cura clinica. Efeitos colaterais foram observados em 11 doentes (7,4%), sendo que dois necessitaram abandonar o tratamento por intolerancia (um teve nauseas de grau moderado e outro, nauseas, vomitos e tonturas de grau moderado, ambos no 1o. dia de tratamento).O ketoconazole por via oral demonstrou ser bastante eficaz no tratamento de pitiriase versicolor e de dermatofitoses
