1. Effects of turbinoplasty versus outfracture and bipolar cautery on the compensatory inferior turbinate hypertrophy in septoplasty patients
Resumo Introdução: A causa mais comum de falha da septoplastia é a hipertrofia das conchas inferiores não tratada adequadamente. Diversas técnicas foram descritas até o momento: turbinectomia total ou parcial, ressecção da submucosa (cirúrgica ou com microdebridador) e a fratura lateral. Objetivo: Neste estudo, comparamos os volumes pré e pós-op

2. An anterior neurovascular interval approach to coronal shear fractures of the distal humerus: a prospective clinical study with short- to mid-term follow-up
RESUMO OBJETIVO: Explorar o efeito do tratamento com uma abordagem anterior do intervalo neurovascular médio para fraturas de cisalhamento coronal da porção distal do úmero. METODOLOGIA: Este estudo prospectivo incluiu duas pacientes do sexo feminino de 30-64 anos de idade, com idade média de 47 anos. As fraturas foram causadas por quedas de bicicleta

3. Influence of remaining coronal thickness and height on biomechanical behavior of endodontically treated teeth: survival rates, load to fracture and finite element analysis
Abstract Objective To evaluate the effect of restorative strategy (fiber post vs cast post and core), coronal height (0 mm vs 2 mm) and thickness (higher than 1 mm vs lower than 1 mm) on survival rate, fracture resistance and stress distribution. Material and Methods Seventy-two bovine teeth were cleaned and allocated in six groups (n = 12). Twenty-four te

4. REPRODUCIBILITY OF SCHATZKER CLASSIFICATION THROUGH SMARTPHONE APPLICATIONS
ABSTRACT Objective: To evaluate the intra-observer reproducibility of Schatzker classification for tibial plateau fractures through smartphone applications. Methods: Radiographs were evaluated in two incidences (anteroposterior and profile) and CT slices (axial, sagittal and coronal) of 37 patients with tibial plateau fracture. Two evaluators, knee surge

5. Influence of crosshead speed on failure load and failure mode of restored maxillary premolars
We analyzed the effect of the crosshead speed of an applied load on failure load and failure mode of restored human premolars. Fifty intact, noncarious human premolars were selected. Class II mesio-occlusodistal preparations were made with a water-cooled high-speed preparation machine, and the teeth were restored with composite resin. The specimens were divi

6. The value of magnetic resonance imaging in the diagnosis of penile fracture
Purpose We studied the use of magnetic resonance imaging in the diagnosis of penile fracture. Materials and Methods Between 1997 and 2012, fifteen patients (age range 17-48 years, mean age 37 years) with suspected penile fracture underwent MRI examinations. Ten patients were injured during sexual intercourse, whereas four patients were traumatized by non-ph

7. Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT
Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. Material and Methods The sample for this study consisted of 242 patients (aging f

8. Internal fixators: a safe option for managing distal femur fractures?
OBJECTIVE: Evaluate safety and reliability of internal fixator for the treatment of intra-articular and periarticular distal femur fractures. METHODS: Retrospective data evaluation of 28 patients with 29 fractures fixed with internal fixator was performed. There was a predominance of male patients (53.5%), with 52% of open wound fractures, 76% of AO33C

9. Eficiência de corte de instrumentos rotatórios de níquel-titânio para alargamento cervical de canais radiculares : análise em estereomicroscopia, perfilometria e microtomografia computadorizada
This study aimed to: evaluate, using different methods and substrates, the cutting efficiency of nickel-titanium rotary instruments for coronal flaring; investigate the influence of rotational speed and number of uses on the cutting efficiency of such instruments; observe the presence of surface defects. First, bovine dentin blocks (n=20) and acrylic blocks

10. Influência do tipo de reconstrução coronoradicular e remanescente dentário no comportamento biomecânico de incisivos tratados endodonticamente
O objetivo deste estudo foi avaliar a influência do tipo de coroa, retentor e a quantidade de remanescente coronário na distribuição de tensões, deformação, resistência à fratura e padrão de fratura de incisivos centrais tratados endodonticamente. Para geração do modelo 3D foi selecionado incisivo central superior hígido. A geometria do esmalte

11. Avaliação da reparação da fratura de côndilo mandibular e da simetria facial em ratos tratados com metotrexato / Evaluation of mandibular condyle fracture repair and facial symmetry in rats treated with methotrexate
O Metotrexato (MTX) é utilizado em altas doses no tratamento de neoplasias e em baixas doses como antiinflamatório. O objetivo deste estudo foi avaliar a reparação da fratura de côndilo mandibular e a simetria facial em ratos tratados com MTX. Foram utilizados 100 ratos, Wistar, machos que foram submetidos a procedimento cirúrgico utilizando modelo exp

12. Influence of remaining coronal structure and finish line on the fracture strength of roots restored with metallic posts
The purpose of this study was to evaluate the fracture strength of roots that were prosthetically restored with metallic posts with or without any remaining coronal structure and with different finish lines. Sixty bovine incisors were sectioned below the cementoenamel junction, endodontically treated, and randomly divided into six experimental groups (n = 10
