Several similar projections utilizing cranial and caudal angulation of the X-ray tube in various obliquities have been described recently for coronary angiography and left ventriculography. These views provide improved visualization of the proximal branches of the left coronary artery, the region of the crux of the right coronary artery, and the left ventricle in the left anterior oblique proje...

Abstract Dental implants are fixtures that constitute for the replacements of root a missing natural tooth. implant therapy has been widely used restoration partially and fully edentulous patients. The literature emphasizes importance passively fitting prosthesis to prevent prosthodontic complications or even loss fixture integration. Failure achieve force tightening superstructure may result i...

OBJECTIVE The goal of this study was to assess effects of translation (horizontal displacement) and angulation (transducer tilting) on 3-dimensional (3D) echocardiographic volumes of both balloons and human left ventricles after autopsy. METHODS Six water-filled (non-) aneurysmatic balloons of 150, 250, and 350 mL and 3 hearts of different sizes and shapes were suspended upright in a water ba...

OBJECTIVES The aim of this study was to analyze the relationship between beam angulation and air kerma in a modern cardiac catheterization laboratory. BACKGROUND Recent reports have identified the merits of reducing radiation scatter, an important determinant of radiation dose in the catheterization laboratory. Radiation scatter is poorly characterized in the context of catheterization labora...

Introduction: Surgical removal of the mandibular third molar has its own set complications. The impacted teeth are in proximity to Inferior Alveolar Nerve (IAN), Buccal Nerve, and Lingual (LN). Therefore, each these nerves is always at risk injury during extraction. Objectives: This study was evaluate anatomical factors nerve after surgical extraction molars patients visiting department oral ma...

Introduction: Polishing after scaling and root planing provides a smoother tooth surface improves patient convenience. Recently, novel polishing system using the air-driven high-pressured device is introduced, but advantage over conventional still questionable. This article aims to provide comprehensive literature study regarding dental by comparing roughness air systems. To conduct this review...

Background: There is constant advancement in aesthetic material used dentistry due to increase demand of aesthetics.
 Objectives:
 
 “To evaluate fracture resistance and pattern failure ETT restored with PEEK post no ferule.”
 1mm ferule length.”
 2mm compare the above groups each other.”
 Methods: 30 human RC treated mandibular premolar teeth single root will be d...

The accuracy of measuring angulation of stable proximal humerus fractures using the axillary lateral projection was investigated. A closing wedge osteotomy with apex anterior angulation was performed on two cadaveric humeri to simulate a stable surgical neck fracture. One specimen was fixed at 30 degrees angulation and the other at 55 degrees. Axillary radiographs were taken with each specimen ...

The differences in angulation and length observed for the fibers of anatomical muscles may reflect two distinct mechanical requirements: arrangement for pinnation, reflecting an increase in physiological cross-section and arrangement for equivalent placement of sarcomeres, possibly associated with coordination. The observed differences in fiber angulation and length have different effects upon ...

OBJECTIVE To evaluate stainless steel archwire static friction in active and passive self-ligating lingual and conventional brackets with second-order angulations. METHODS Two conventional lingual brackets for canines (STb light/Ormco; PSWb/Tecnident), and two self-ligating brackets, one active (In-Ovation L/GAC) and the other passive (3D/ Forestadent), were evaluated. A stainless steel archw...
