This retrospective study aimed at determining the predicted risks of clinical and radiographic complications in primary teeth following traumatic dental injuries, according to injury type, severity and child's age. Data were collected from records of children treated at a Dental Trauma Center in Brazil for nine years. Records of 576 children were included; clinical sequelae were assessed in 774...

Small-scale domes with circumferential aprons and concentric aureoles in western Arcadia Planitia (34–41°N, 167–179°E) near Tyndall crater were examined using a suite of datasets including CRISM, THEMIS IR, HiRISE, CTX. Previous studies based primarily on photogeologic evidence suggested that these analogous to terrestrial felsic cryptodomes extrusive lava domes. The have also been CRISM visibl...

Abstract Oceanic Transform Faults are one of manifestations the three major plate boundaries and a key tectonic feature oceanic crust. They broadly considered to accommodate strike‐slip displacement along simple vertical faults be largely without magmatic addition. We present first observations from broadband 3D seismic buried, Cretaceous‐aged transform in Gulf Guinea with complex internal arch...

provide a test for the hypothesis of faunal change at the Triassic-Jurassic boundary recently proposed by OLSEN and SUES (1986). They are remarkable for the numerical abundance and quality of preservation of the bones, the lithological diversity of fossil-bearing deposits, and the excellent degree of stratigraphic resolution. The vertebrate remains from the McCoy Brook Formation currently repre...

AIM The aim of this study was to evaluate the main post-traumatic complications of severe luxation and replanted teeth using clinical and radiographic analyses. MATERIALS AND METHODS Eighty-three patients aged between 7 and 55 years old presenting 180 traumatized teeth that suffered extrusive luxation (n=67), lateral luxation (n=69), intrusive luxation (n=10) and tooth avulsion (n=34) followe...

Following phagocytosis in vivo, acidification of extracellular pH (pH(o)) and intracellular metabolic acid generation contribute to cytosolic proton loading in neutrophils. Cytosolic pH (pH(i)) affects neutrophil function, although its regulation is incompletely understood. Its effect on mechanisms of neutrophil death is also uncertain. Thus, we investigated pH(i) regulation in Escherichia coli...

The objectives of this study were to comparatively assess the magnitude and direction of forces and moments generated from different bracket systems, during the initial levelling and alignment stage of orthodontic treatment. Three types of brackets were used: Orthos2 (Ormco), Damon2 (Ormco), and In-Ovation R (GAC). The brackets were bonded on resin replicas models of a patient's crowded mandibu...
