Particulate production during orthodontic production laboratory procedures.

Dental technicians are exposed to respirable particles during their everyday work. This study investigated particulate production during dental laboratory procedures. Real-time air sampling of dental laboratory production processes was carried out, including the use of a plaster hopper, trimming study models and the trimming and polishing of removable orthodontic appliances.

Quantitative and qualitative analysis of particulate production during simulated clinical orthodontic debonds.

Objectives: The objectives of this investigation were firstly to quantitatively and qualitatively determine particulate production during orthodontic debond and enamel cleanup procedures, and secondly to examine what methods can be employed to minimize operator exposure to such dust particles.

Methods: A qualitative study was performed to determine the aerodynamic diameters and compositions of particulates produced during simulated clinical debonds and enamel cleanup procedures on extracted teeth. In each case the enamel was cleaned using tungsten carbide burs in either a high or slow speed handpiece, with or without water coolant spray, with or without high volume evacuation (HVE) or a face mask.

Body temperature management after severe traumatic brain injury: methods and protocols used in the United Kingdom and Ireland.

Objective: To establish whether there is consensus in the management of body temperature in patients with severe traumatic brain injury (TBI) admitted to hospitals in the United Kingdom and Ireland for neurosurgical intensive care.

Methods: Permission was granted from the Society of British Neurosurgeons (SBNS) and the Local Research Ethics Committee to undertake the survey. A senior member of nursing staff from all adult neurosurgical units, excluding our own, was contacted by telephone.
