A new technique for the fabrication of composite resin direct veneers is presented. In this technique, a transparent acrylic resin matrix is fabricated before preparation of the facial surface of the tooth, to allow the adequate reproduction of contour, shape, and surface texture originally exhibited by the tooth. Advantages, as well as limitations, of the procedure are also presented.
We describe a child with dermatomyositis and calcified necrosis in the middle third of both ureters. Histopathological examination showed vasculitis associated with ureteral necrosis and calcification. These findings together with a similar previous report in the literature have prompted us to correlate dermatomyositis in childhood with ureteral necrosis and to anticipate specifically a lesion in the middle third of the ureter because of the relative lack of blood flow in that segment.
