Comparative Study
A comparative evaluation of smear layer removal by using different Er:YAG lasers parameters: An İn-vitro scanning electron microscopic study.
The purpose of this in-vitro study was to investigate the effect of irrigation activation methods using different laser parameters on microhardness and push-out bonding strength of root canal dentin. This study evaluates and compares the efficacy of different laser parameters in smear layer removal using the scanning electron microscopic image analysis. ⋯ According to this study the laser group increases the bonding strength without a negative change in microhardness. In this study the further research is needed on this subject.

Medical waste management (MWM) is of concern to the medical and general community. Adequate knowledge regarding management of healthcare waste is an important precursor to the synthesis of appropriate attitudes and practices of proper handling and disposal of medical waste by healthcare workers (HCWs). ⋯ This study showed that MWM practice at this facility was above average, although improvements were required in accessing waste disposal points and availability of personal protective equipment. Ongoing training should be provided to HCWs on MWM, with more attention to knowledge of regulatory requirements, and involvement of HCWs in development of MWM policies to enhance compliance.

Today, the internet is widely used to obtain any type of information. The use of internet may facilitate healthcare professionals' education as well. ⋯ Videos regarding medical skills should be accurate. Information on YouTube regarding intubation is limited and is of low quality. The establishment of an organization authorized to evaluate the content, quality, accuracy and reliability of the information on the internet regarding medical skills is warranted.

Glial fibrillary acidic protein (GFAP) is a brain-specific astroglial protein that is released into the blood soon after traumatic brain injury by mature astrocytes. S100B is rapidly released into the cerebrospinal fluid and bloodstream after brain damage. We compared the serum concentrations of these proteins in patients with severe head trauma (bleeding and/or fracture) or nontraumatic intracerebral hemorrhage and healthy individuals. ⋯ The GFAP and S100B concentrations were significantly higher in patients with traumatic or nontraumatic brain injury than in healthy individuals, indicating that serum levels of these biomarkers may provide an alternative to computed tomography for the diagnosis of brain injury.

The aim of this study was to compare in vitro fracture strengths (FSs) of metal- and fiber-reinforced frameworks of resin-bonded bridges and to evaluate stress distribution with finite element analysis (FEA). ⋯ In vitro FSs of MR-RB and the stress concentration of the point that the forces were applied were higher as compared to other parts of the restoration. Furthermore, in contrast to FR-RB specimens, retainer tooth fractures were observed in MR-RB specimens.
