Study finds difference in way bipolar disorder affects brains of children versus adults June 18, A new study from Bradley Hospital has found that bipolar children have greater activation in the right amygdala — a brain region very important for emotional reaction — than bipolar adults when viewing emotional faces. Study details risk factors for substance use disorders after manic episode July 22, Medical Xpress —Adolescents with bipolar disorder are more likely to develop substance use disorders than adolescents without psychiatric disorders. Now, researchers at the University of Cincinnati UC have identified
Feb 13, Nanotechnology in dentistry - applications, hazards, benefits Nanowerk News There appears to be many potential benefits to patient outcome from using nanotechnology in dentistry.
Interactions with the Nano dentistry Microenvironment, Clinical Applications, Hazards, and Benefits" aims to detail the ultrafine structure, chemical composition, and reactivity of dental tissues in the context of interactions with ENMs, including the saliva, pellicle layer, and oral biofilm; then describes the applications of ENMs in dentistry in context with beneficial clinical outcomes versus potential risks.
The use of engineered nanomaterials ENMs to enhance themechanical and physiological Nano dentistry of the tooth via new nanofillers and composites should provide an enhanced capability for some areas of restorative dentistry.
The use of ENMs to improve osseointegration, infection control, and biocompatibility of dental implants may reduce the rejection rates in some invasive procedures. There are also completely new frontiers in dental treatment such as the use of ENMs to control and direct pulp stem cells in order to regenerate the tooth.
These potential benefits should be balanced against the risks. For the patient the exposure to ENMs will be controlled by the planned dental treatment, and thus, the main concern is on the hazard of the ENMs in dental materials.
The data so far indicates that oral toxicity for ENMs is low, but some ENMs are translocated across the gut to cause systemic disturbances, perhaps with organ pathology. However, the matrix in which the ENM is incorporated will be important, and oral toxicity studies have yet to be done with dental materials containing EMNs.
Overall, however, the information so far indicates that the oral hazard is low or manageable and should not be a barrier to the safe innovation of nanotechnology in dentistry.
The safety assessment processes in place for medicines and medical devices remain robust, and although individual toxicity tests may need modifications to work well with ENMs, the overall safety strategy is appropriate. Nonetheless, there are some improvements in health and safety that can be made.
For example, better guidance to practitioners on nano-incorporated products with respect to patient safety and occupational health.
For the public and patients, the nanospecific labeling on the many personal care products in dentistry could be improved to clearly identify the nanoingredient s. Thus, giving clarity on whether a product actually contains an ENM and what the proposed mode of action or benefit of the new product might be to the consumer.Sessions and Tracks.
Track 1: Dental Public Health.
Dental public health is the strength of dentistry that advances oral prosperity and furthermore the aversion and control of dental infections. The American Association of Public Health Dentistry perceives a couple of ways that dental specialists can propel oral prosperity, like, assessing the oral prosperity needs of the gathering, making and.
New Funding Opportunity: PFAS in Landfills and Groundwater. Practical Methods to Analyze and Treat Emerging Contaminants (PFAS) in Solid Waste, Landfills, Wastewater/Leachates, Soils, and Groundwater to Protect Human Health and Environment Request for Application (RFA) is now open until Octob er 2, Dr Lorraine Bruce.
Partner, BDS GDC: Originally from Peterhead, Lorraine qualified from the University of Glasgow in She then went on to take up a post in the Dundee Dental Hospital and School, gaining experience in oral surgery and restorative dentistry.
Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, biotechnology including tissue engineering, and, ultimately, dental nanorobotics (nanomedicine). When the first micron-size dental nanorobots can be constructed in years, these devices will allow precisely controlled oral analgesia.
May 22, · Nanotechnology is a new transnational and transcultural development that is growing rapidly and pervasively. The potential impact of novel Nanodentistry Applications in disease diagnosis, therapy and prevention is foreseen to change oral health care in a fundamental way. 1 review of Nano Dentistry "I hate dentists.
No, seriously, I do. Ever since I was a kid and I had the most horrible, verbally abusive country dentist, I've been terrified to go back. Even the thought of a cleaning had me running for my 5/5(1).
