The solubility, pH, electrical conductivity, and radiopacity of AH Plus and MTA FillApex were evaluated. In addition, the surfaces morphologies of the sealers were analyzed by using scanning electron microscopy. For pH test, the samples were immersed in distilled water at different periods of time. The same solution was used for electrical conductivity(More)
We have analysed the predictors of postoperative complications and the need for reoperation after grafting of the alveolar cleft from one specialised cleft centre. The data were obtained from hospital casenotes of patients operated on from December 2004 to April 2010, with a minimum one-year follow-up from the final operation. Independent variables included(More)
Cavernous sinus thrombosis is a severe encephalic complication of the cervicofacial infections that can lead to death if not treated in adequate time. Among the several etiologies related to the development of this infection, myiasis has not been reported, enforcing the importance of the report of a case of thrombosis of the cavernous sinus developed from a(More)
OBJECTIVE Keratocystic odontogenic tumors (KOTs) can be treated with Carnoy's solution, although this treatment modality is not free from complications. It is important to verify the incidence of complications after the use of Carnoy's solution and compare these with the literature. MATERIALS AND METHODS This study verified the effects of a complementary(More)
Mandibular position is an important parameter used for the diagnosis of dentofacial deformities, as well as for orthognathic surgery planning and execution. Centric relation (anterior and superior relationship of the mandibular condyles interposed by the thinnest portion of their disks against the articular eminencies), centric occlusion (when lower teeth(More)
There may be significant variation amongst oral and maxillofacial surgeons (OMFS) in the identification and placement of cephalometric landmarks for orthognathic surgery, and this could impact upon the surgical plan and final treatment outcome. In an effort to assess this variability, 10 lateral cephalometric radiographs were selected for evaluation by 16(More)
Craniofacial defects represent alterations in the anatomy and morphology of the cranial vault and the facial bones that potentially affect an individual's psychological and social well-being. Although a variety of techniques and restorative procedures have been described for the reconstruction of the affected area, polymethyl methacrylate (PMMA), a(More)
The lymphoepithelial cyst is a dysontogenic benign cyst originated from the epithelial remnant retained inside the lymphoid tissue during the embryogenesis that occurs in the lateral neck region and, less frequently, in the oral cavity and in the parotid gland. The parotid gland evolvement increased significantly after the HIV discovery and it is related to(More)
Objective To evaluate the ability to open the mouth in patients undergoing radiotherapy for head and neck and the variables related to this limitation. Methods 32 patients were evaluated six months after completion of radiotherapy sessions to treat cancer in the head and neck. The maximum mouth opening was measured using digital calipers and its association(More)
Obtaining a good cosmetic and proper mastication in oral rehabilitation with dental implants are directly linked to the correct positioning of the implant in the alveolar bone. The malposition of the implant is a challenge in rehabilitation, which can often compromise the entire process. In cases of severely malpositioned implants, one has the option to(More)
