The predictive role of aortic propagation velocity for coronary artery disease.

Background: It is well recognized that cardio- vascular risk factors lead to histological and functional changes in aorta, and aortic stiffness is the best predictor of cardiovascular morbidity and mortality. In this study we evaluated the relation of a less evaluated echocardiographic parameter of aortic stiffness, aortic propagation velocity (APV) with the presence and severity of CAD.

Methods: This cross sectional study was conducted from May 2015 to March 2016 in Imam Reza hospital, Mashhad, Iran.

Multidisciplinary Management of Candidates for Maxillary Sinus Augmentation by a Surgeon and ENT Specialist.

Maxillary sinus augmentation has been shown to be a predictable treatment option for placing dental implants in areas of posterior maxilla with lack of sufficient residual alveolar bone height. The transalveolar (crestal) and the lateral window are the main techniques for the maxillary sinus augmentation with the goal of creating a space beneath the Schneiderian membrane in which to place various grafting materials in order to increase alveolar bone height.

Maintaining Osseointegration: Understanding, preventing, and treating Risk Factors for Peri-implant Diseases.

The dental implant is a predictable way of restoring fully and partially edentulous patients and has shown high success rate for managing a broad range of clinical conditions. Improving implant surfaces has revolutionized the osseointegration of implants and changed the focus of implant research from osseointegration more toward the risk factors associated with the failure of implants in the long-term.

Maxillary Sinus Grafting With Biphasic Bone Ceramic or Autogenous Bone: Clinical, Histologic, and Histomorphometric Results From a Randomized Controlled Clinical Trial.

Purpose: The present, randomized, controlled clinical trial compared the histologic and histomorphometric results from maxillary sinus augmentation with either biphasic calcium phosphate (BCP) (60% hydroxyapatite and 40% β-tricalcium phosphate) or autogenous bone (AB) as bone-grafting materials.

Material And Methods: Ten patients received bilateral sinus elevation surgery with intraoral AB chips (control group) on one side and BCP (test group) on the contralateral side. After a healing period of 6 to 8 months, implant sites were created and trephine cores were harvested for histological and histomorphometric analysis of the grafted areas.

Peri-implant Diseases: What do We know and What do We need to know?

As the demand for implant restorative therapy increases worldwide, peri-implantitis is considered to be a major challenge for clinicians. Peri-implant diseases are inflammatory in nature and might be limited to the soft tissue, peri-implant mucositis, or extend to the supporting alveolar bone that is called peri-implantitis.(1).

Radiographic Evaluation of Maxillary Sinus Lateral Wall and Posterior Superior Alveolar Artery Anatomy: A Cone-Beam Computed Tomographic Study.

Objective: The purpose of the current study is to assess the thickness of the maxillary sinus lateral wall in dentate and edentulous patients using cone beam computed tomography (CBCT). This study also provides information about the diameter, prevalence, and course of the posterior superior alveolar artery (PSAA), and its relation to the maxillary sinus floor.

Materials And Methods: Four hundred and thirty CBCT scans of the maxillofacial complex (860 maxillary sinuses) were reviewed.

A comprehensive clinical review of maxillary sinus floor elevation: anatomy, techniques, biomaterials and complications.

Several systematic reviews have shown that maxillary sinus augmentation is a predictable and effective procedure for augmentation of an atrophic posterior maxilla. However, we know of no reviews that have covered all the clinical aspects. We searched the PubMed, EMBASE, Cinhal, and Cochrane databases up to January 2015 to select relevant studies that cover the different objectives of this review, including the anatomy of the maxillary sinus, surgical techniques, biomaterials used in the sinus augmentation, and potential complications.

Comprehensive review of hyperbaric oxygen therapy.

Hyperbaric oxygen therapy involves inspiration of pure high pressure oxygen. For the past 20 years, administration of 100% high pressure oxygen and its potential benefits in management of diseases have been more clarified. Physiological advantages advocate HBO for the first-line treatment of several conditions.

Clinical assessment of orofacial manifestations in 500 patients with multiple sclerosis.

Purpose: The aim of the present study was to determine the incidence of orofacial manifestations in patients with multiple sclerosis (MS) and to assess the factors associated with these symptoms. The dental implications of this disease are discussed.

Patients And Methods: The study included 500 patients 11 to 69 years old with MS.

Frontal sinus agenesis using computed tomography.

In adults, paranasal sinus agenesis is an uncommon anomaly that appears mainly in the frontal sinus. The aim of this study was to investigate the prevalence of agenesis of the frontal sinus using computed tomography in a population of Iranian individuals. Computed tomographic scans in the axial and coronal planes of the frontal sinus of 565 patients were examined for evidence of the absence of the frontal sinus.

Effect of 10% sodium ascorbate hydrogel and delayed bonding on shear bond strength of composite resin and resin-modified glass ionomer to bleached enamel.

Objective: The aim of this study was to comparatively investigate the neutralizing effect of antioxidant treatment and delayed bonding after bleaching with hydrogen peroxide on the shear bond strength of a composite resin (CR) and resin-modified glass ionomer (RmGI) to enamel.

Materials And Methods: Ninety-six freshly extracted human 3rd molars with flat enamel surfaces were divided into six experimental groups (n=12/group) and two control groups (n=12/group). After initial preparation, specimens in Groups 1 and 5 (control groups) were not bleached and the buccal enamel surface of specimens were bonded immediately with CR and RmGI.
