Resumo

O microscópio clínico é um método comumente utilizado para a magnificação do campo operatório em procedimentos endodônticos. Durante a cirurgia parendodôntica, o microscópio clínico permite ao profissional realizar procedimentos de osteotomia mais conversadores, inspecionar a retrobturação, e a detectar fracturas radiculares, perfurações ou a presença de canais acessórios na superfície radicular. Este estudo avaliou, ex vivo, a presença e o número de foraminas acessórias com o uso do microscópio clínico, comparando com o microscópio electrónico de varredura. Foram selecionados cinquenta dentes, inicialmente analisados no microscópio clínico, em aumento de 32 vezes. Foi observada e registada a quantidade de foramina principais e foramina acessórios. Em seguida, as raízes foram preparadas para o exame no microscópio electrónico de varredura, em um aumento de 35 vezes. Foi comparado o número de foramina acessórios detectados pelo microscópio clínico e pelo electrónico de varredura. O uso do microscópio clínico identificou 46% das foramina acessórios presentes.

Abstract

The operatory microscope is a device commonly used for magnification of the surgical field and it has been recommended during endodontic treatment. During apical surgery, this device allows the professional to do a more conservative bone removal, to inspect the retrofilling, to detect root cracks, perforations or accessory canals. This ex vivo study evaluated the number of foramina using the operating microscope and the scanning electron microscope. Fifty maxillary anterior teeth were evaluated using a surgical operatory microscope, at a magnification of 32x and the number of apical foraminal opening was recorded. Then, the roots were prepared for scanning electron microscope analyses (SEM), at a magnification of 35x. The number of accessory foramina was investigated using both OM and SEM, and these analyses were compared. The operatory microscope was able to identify 46% of the existing foramina.
