Air pollution and respiratory diseases: ecological time series

Säo Paulo med. j; 134 (4), 2016
ABSTRACT CONTEXT AND OBJECTIVE: Exposure to air pollutants is one of the factors responsible for hospitalizations due to respiratory diseases. The objective here was to estimate the effect of exposure to particulate matter (such as PM2.5) on hospitalizations due to certain respiratory diseases among re...

Subjective visual vertical with the bucket method in Brazilian healthy individuals

ABSTRACT INTRODUCTION: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical. OBJECTIVE: To evaluate subjective visual vertical using the bucket method in health...

Primary Hyperparathyroidism: The Influence of Bone Marrow Adipose Tissue on Bone Loss and of Osteocalcin on Insulin Resistance

Clinics; 71 (8), 2016
OBJECTIVES: Bone marrow adipose tissue has been associated with low bone mineral density. However, no data exist regarding marrow adipose tissue in primary hyperparathyroidism, a disorder associated with bone loss in conditions of high bone turnover. The objective of the present study was to investigate ...

The impact of clinical use on the torsional behavior of Reciproc and WaveOne instruments

J. appl. oral sci; 24 (4), 2016
ABSTRACT Torsional overload is a fracture representative parameter for instruments in single-file techniques. Objective The aim of this study was to assess the influence of clinical use, in vivo, on the torsional behavior of Reciproc and WaveOne instruments considering the possibility that they degrade...

Influence of resin cement shade on the color and translucency of ceramic veneers

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objective This in vitro study evaluated the effect of two different shades of resin cement (RC- A1 and A3) layer on color change, translucency parameter (TP), and chroma of low (LT) and high (HT) translucent reinforced lithium disilicate ceramic laminates. Material and Methods One dual-cured...

MMP1-1607 polymorphism increases the risk for periapical lesion development through the upregulation MMP-1 expression in association with pro-inflammatory milieu elements

J. appl. oral sci; 24 (4), 2016
ABSTRACT Increased matrix metalloproteinases (MMPs) activity is a hallmark of periapical granulomas. However, the factors underlying the MMPs expression modulation in healthy and diseased periapical tissues remains to be determined. Objective In this study, we evaluated the association between the MMP1...

Comparison of the marginal adaptation of direct and indirect composite inlay restorations with optical coherence tomography

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objective The purpose of the study was to use the photonic imaging modality of optical coherence tomography (OCT) to compare the marginal adaptation of composite inlays fabricated by direct and indirect techniques. Material and Methods Class II cavities were prepared on 34 extracted human mo...

Periodontal disease and inflammatory blood cytokines in patients with stable coronary artery disease

J. appl. oral sci; 24 (4), 2016
ABSTRACT Periodontal disease has been associated with elevations of blood cytokines involved in atherosclerosis in systemically healthy individuals, but little is known about this association in stable cardiovascular patients. The aim of this study was to assess the association between periodontal diseas...

Cytotoxicity and cytokine expression induced by silorane and methacrylate-based composite resins

J. appl. oral sci; 24 (4), 2016
ABSTRACT The successful use of composite resins in Dentistry depends on physicochemical properties, but also on the biological compatibility of resins, because of the close association between pulp and dentin. Objective The aim of this study was to evaluate cytotoxicity and cytokine production induced ...

Serum lipid profile and clinical characteristics of patients with xanthelasma palpebrarum

An. bras. dermatol; 91 (4), 2016
Abstract: Background: Although many factors are involved in the etiology of xanthelasma palpebrum, lipid disorder is strongly associated with its induction. Xanthelasma palpebrum, the most common type of xanthoma, usually presents in middle-aged females and results in aesthetic problems. Objective: To ...
