A simplified low-cost phantom for image quality assessment of dental cone beam computed tomography unit.

Introduction: A standardised testing protocol for evaluation of a wide range of dental cone beam computed tomography (CBCT) performance and image quality (IQ) parameters is still limited and commercially available testing tool is unaffordable by some centres. This study aims to assess the performance of a low-cost fabricated phantom for image quality assessment (IQA) of digital CBCT unit.

Methods: A customised polymethyl methacrylate (PMMA) cylindrical phantom was developed for performance evaluation of Planmeca ProMax 3D Mid digital dental CBCT unit.

Enhancement of Tech-Sil25 Maxillofacial Silicone Mechanical Properties after Artificial Weathering through Addition of Nanoparticles.

Purpose: To evaluate the effect of nanosilica and nanoalumina addition in Tech-sil25 maxillofacial silicone before and after exposure to artificial weathering conditions.

Materials And Methods: A total of 144 samples were divided into four groups, a control group ( = 12) and three test groups, nanosilica (NS) ( = 36), nanoalumina (NA) ( = 36), and a hybrid nanoparticle (HySA) ( = 60) at different weight percentages (1, 2, and 3 wt. %) was added to Tech-sil25.

Model-based glycemic control in a Malaysian intensive care unit: performance and safety study.

Stress-induced hyperglycemia is common in critically ill patients. A few forms of model-based glycemic control have been introduced to reduce this phenomena and among them is the automated STAR protocol which has been used in the Christchurch and Gyulá hospitals' intensive care units (ICUs) since 2010. This article presents the pilot trial assessment of STAR protocol which has been implemented in the International Islamic University Malaysia Medical Centre (IIUMMC) Hospital ICU since December 2017.

In Vitro Mean Red Blood Cell Volume Change Induced by Diode Pump Solid State Low-Level Laser of 405 nm.

Objective: This study was conducted to investigate the effects of low-level laser (LLL) doses on human red blood cell volume. The effects of exposure to a diode pump solid state (DPSS) (λ = 405 nm) laser were observed.

Background Data: The response of human blood to LLL irradiation gives important information about the mechanism of interaction of laser light with living organisms.
