OBJECTIVE The aim of this study was to investigate the effects of photodynamic therapy (PDT) on endodontic pathogens by evaluating the decrease in numbers of Enterococcus faecalis colonies in the canals of extracted human teeth. BACKGROUND DATA Failure in endodontics is usually related to inadequate cleaning and disinfection of the root canal system. This(More)
UNLABELLED To identify the grade and evolution of dysphagia and dysphonia in patients undergoing supracricoid laringectomy, and to study the association of these findings with clinical and surgical variables. METHOD The study included 22 cases undergoing supracricoid laringectomy at the Head and Neck Surgery and Otolaryngology Department of the Heliopolis(More)
The aim of this study is to evaluate the efficacy of the application of allogenous bone at the maxillomandibular reconstructions for future rehabilitation with dental implants. The patients were submitted to reconstruction of maxilla, using allogeneic bone grafts, in 3 different techniques: onlay grafts for lateral ridge augmentation, onlay and particulate(More)
BACKGROUND To verify the correlation between the micronucleus frequency and the presence of local recurrences or second primary lesion in patients with carcinoma of the oral cavity. METHODS We studied the frequency of micronucleus of the oral mucosa in 27 untreated patients with carcinoma of the oral cavity and oropharynx. The patients were monthly(More)
OBJECTIVES The aim of this study was to determine and compare the frequency of bacterial leakage of Streptococcus sanguinis biotype II along the implant-abutment interface between two systems of morse taper dental implants. Different methods of activation of the taper abutments were used: tapped-in (Bicon) and screwed-in (Ankylos). MATERIALS AND METHODS(More)
Frey syndrome is one of the potential sequelae of parotidectomy. Various medical and surgical treatments have been used in an attempt to avoid this embarrassing condition. Recently, interposing barriers between the overlying skin flap and the parotid bed, such as the sternocleidomastoid muscle (SCM) flap, have been used to prevent this condition. The(More)
CONTEXT The minimal recommended surgical approach to parotid tumors is partial parotidectomy with resection of the superficial lobe of the gland. Histologic diagnosis prior to surgery is not possible, as incisional biopsies are contraindicated due to the possibility of facial nerve injury or incomplete tumor resection. Thus, the biopsies tend to be(More)
Adenoameloblastoma may recur when treated incompletely by curettage. In the rare case of recurrence, an extensive and mutilating resection may become necessary. A correct diagnosis must be made in cases of atypical ameloblastomas in order to avoid unnecessary radical surgery. In doubtful cases, biopsy with histopathologic examination is indicated.(More)
