At the same time, they are providing that care at a reduced cost to the dental practice. The report, released today by Community Catalyst, determined that midlevel dental providers currently practicing in Alaska and Minnesota cost their employers 27 and 29 percent respectively of the revenue they generate. http://medicalxpress.com/news/2013-05-analysis-dental-therapists-access-children.html Dentistry Tue, 14 May 2013 12:48:41 EST news287754515 (HealthDay)—Manifestation of dental erosion caused by illicit drug use or excessive soda consumption needs to be distinguished from dental caries, according to case studies published in the March/April issue of General Dentistry. http://medicalxpress.com/news/2013-05-excessive-soda-mimic-illicit-drug.html Dentistry Mon, 13 May 2013 15:10:01 EST news287667840 Are you wrecking your teeth without even knowing it?

Researchers at the Universitat Jaume I (UJI) in Castellón have developed an implant coating with a novel biodegradable material aimed at people with bone deficit. It will also increase the overall success rate of implants through an enhanced biocompatibility and reduce the time of osseointegration or bone integration. http://medicalxpress.com/news/2013-04-success-tooth-implants.html Dentistry Mon, 29 Apr 2013 09:28:22 EST news286446495 (Medical Xpress)—Scientists of the Max Planck Institute for Evolutionary Anthropology in Leipzig and the Senckenberg Research Institute in Frankfurt together with dental technicians have digitally analysed modern human teeth using an engineering approach, finite element method, to evaluate the biomechanical behaviour of teeth under realistic loading. They report results, showing that very widespread loss of dental material (enamel and dentine) at the base of the crown might be linked to the reduction of tooth wear in our industrialised societies. The study is published today in the professional journal PLoS ONE. http://medicalxpress.com/news/2013-04-material-loss-teeth-fatigue-failure.html Dentistry Thu, 25 Apr 2013 07:25:51 EST news286093544 IQ directly relates to how students perform on tests in the first two years of dental school.

Although the loss of every second tooth is attributable to it, this disease, and its possible consequences, is still not being taken seriously. Corinna Bruckmann, periodontitis expert at the Bernhard Gottlieb University Dental Clinic at the MedUni Wien, also makes this point: "Current figures show that periodontitis escapes the subjective awareness of those affected, in older people even more so than in younger ones." http://medicalxpress.com/news/2013-04-periodontitis-underestimated-danger.html Dentistry Wed, 17 Apr 2013 09:47:45 EST news285410858 Silver tooth fillings have been placed in the mouths of Americans since before the Civil War, an inexpensive, durable and reliable material that helped form the foundation of modern dentistry. http://medicalxpress.com/news/2013-04-dental-amalgam-anti-mercury-movement-shifts.html Dentistry Thu, 04 Apr 2013 09:30:01 EST news284281797 Researchers from Tufts University School of Dental Medicine have discovered a statistical association between the injection of local dental anesthesia given to children ages two to six and evidence of missing lower wisdom teeth. The results of this epidemiological study, published in the April issue of The Journal of the American Dental Association, suggest that injecting anesthesia into the gums of young children may interrupt the development of the lower wisdom tooth. http://medicalxpress.com/news/2013-04-dental-anesthesia-wisdom-teeth-children.html Dentistry Wed, 03 Apr 2013 11:05:53 EST news284205839 Researchers at Tufts University School of Dental Medicine and the Forsyth Institute published a study today that found that a significant proportion of dental bib clips harbored bacteria from the patient, dental clinician and the environment even after the clips had undergone standard disinfection procedures in a hygiene clinic. Although the majority of the thousands of bacteria found on the bib clips immediately after treatment were adequately eliminated through the disinfection procedure, the researchers found that 40% of the bib clips tested post-disinfection retained one or more aerobic bacteria, which can survive and grow in oxygenated environments. They found that 70% of bib clips tested post-disinfection retained one or more anaerobic bacteria, which do not live or grow in the presence of oxygen. http://medicalxpress.com/news/2013-04-dental-bib-harbor-oral-skin.html Dentistry Tue, 02 Apr 2013 01:00:01 EST news284036686 Just 40 years ago, more than half of American kids had at least one untreated cavity.

Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant.

Bleeding gums during brushing or when biting into an apple could be an indication of periodontitis, an inflammatory disease of the tissues that surround and support the teeth. Bacterial plaque attacks the bone, meaning teeth can loosen over time and in the worst case even fall out, as they are left without a solid foundation to hold them in place. Furthermore, periodontitis also acts as a focal point from which disease can spread throughout the entire body: If the bacteria, which can be very aggressive, enters the bloodstream, they can cause further damage elsewhere. Physicians suspect there is a connection between periodontitis pathogens and the sort of cardiovascular damage that can cause heart attacks or strokes. In order to stop the source of inflammation, dentists remove dental calculus and deposits from the surface of teeth, but this is often not enough; aggressive bacteria can only be eliminated with antibiotics. http://medicalxpress.com/news/2013-02-millions-germans-periodontitis.html Dentistry Fri, 01 Feb 2013 06:27:18 EST news278922414 (Medical Xpress)—Researchers from the University of Adelaide say any health warnings about soft drinks should include the risk of tooth decay, following a new study that looks at the consumption of sweet drinks and fluoridated water by Australian children. http://medicalxpress.com/news/2013-01-sweet-tooth.html Dentistry Wed, 30 Jan 2013 08:18:54 EST news278756327 (Medical Xpress)—Children have been shown to significantly prefer a new way of treating tooth decay that doesn't involve needles or drills. http://medicalxpress.com/news/2013-01-drill-less-technique-kids-dentist.html Dentistry Tue, 29 Jan 2013 06:30:06 EST news278663391 Today, the International and American Associations for Dental Research (IADR/AADR) published a paper titled "ß-catenin is Required in Odontoblasts for Tooth Root Formation."
