Evaluation of the Root Canal Morphology of Molars by Using Cone-beam Computed Tomography in a Brazilian Population: Part I.

Introduction: One of the factors influencing the success of endodontic treatment is anatomic knowledge of the root canal system. Because of the difficulties of using conventional radiographic methods to evaluate root canals, cone-beam computed tomography (CBCT) has been very useful for evaluating the morphology of root canals. The purpose of this study was to use CBCT to evaluate differences in the anatomy of the mandibular first molars with respect to the patient's sex and the location of the tooth in a Brazilian population.

Anti-infective periodontal therapy promoting improvement in systemic markers of HIV infection.

Research supports the theory that the chronic infectious response occurring in periodontal disease may have a role as a risk modifier of systemic diseases. This study assessed the impact of HIV-associated chronic periodontitis treatment on systemic HIV-related markers (CD4 T lymphocytes cell counts and HIV viral load). Fifteen HIV patients presenting chronic periodontitis [at least eight sites presenting a probing depth (PD) >4 mm and bleeding] were included in this study.

Laser Therapy of Recurrent Aphthous Ulcer in Patient with HIV Infection.

The recurrent aphthous ulcer (RAU) is a pathological change found in the oral mucosa, characterized by painful single or multiple ulcers. The etiologic aspect of RAU is not well understood; however it is known that due to lower CD4 cell counts patients had higher prevalence of these oral lesions, and immunosuppressed patients with HIV are predisposed. Patient FC is African descent, 26 years old, male, HIV + CD4 67 cells/mm(3), with minor RAU in the upper and lower right side lip, measuring about 4 mm, and major RAU in tongue and the tonsillar pillar measuring 2 cm.

PDT in non-surgical treatment of periodontitis in HIV patients: a split-mouth, randomized clinical trial.

Background And Objective: The aim of this study was to evaluate the clinical and microbiological effect of photodynamic therapy (PDT) in the non-surgical treatment of periodontitis in HIV patients.

Methods: Twelve HIV patients from the CEAPE/UNIP, Brazil, with periodontitis were included in this 6-month, split-mouth, double-blind, controlled clinical trial. Patients were placed in the following groups: Group SRP-scaling and root planning with an ultrasonic device (SRP); and Group SRP + PDT-SRP associated with a course of PDT with a diode laser with a wavelength of 660 nm and 0.
