White Paper on Ethics & Professionalism in Dental Education

by

The American Student Dental Association (ASDA) has recently published a White Paper on Ethics & Professionalism in Dental Education which can be found at http://www.asdanet.org/uploadedFiles/The_Issues/ASDA%20White%20Paper%20Final-Newcomb.pdf The paper is designed to help address issues of cheating which have occurred at dental schools. The ASDA Student Code of Ethics states that, “ASDA recognizes the importance of high ethical standards in the dental school setting. Therefore, the Association believes students should conduct themselves in a manner reflecting integrity and fairness in both the didactic and clinical learning environments. Ethical and professional behavior by dental students is characterized by honesty, fairness, and integrity in all circumstances; respect for the rights, differences, and property of others; concern for the welfare of patients, competence in the delivery of care, and preservation of confidentiality in all situations where this is warranted.” The paper addresses some of the … Read more

ADA EBD Champions Conference 2010

by

The American Dental Association (ADA) is looking for dentists interested in spreading the word about evidence-based dentistry to attend the EBD Champions Conference March 26-27, 2010, at ADA Headquarters in Chicago, IL. The deadline for applications is faster approaching and is Jan. 30, 2010. The conference is sponsored by the ADA and the Journal of Evidence-Based Dental Practice and supported by an educational grant from Procter & Gamble. The event is a unique opportunity for dentists to become resources to their local dental communities by promoting an evidence-based approach to patient treatment and disease prevention. I am glad to see that dentists are gathering to discuss evidence-based dentistry and feel that if you are able to make the conference, it would be well worth it. For more information about the conference or to apply to become an EBD Champion, visit … Read more

Mercury Fillings May Be Less Toxic: Caution Still Needed

by

A new study on the surface chemistry of silver-colored, mercury-based dental fillings suggests that the surface forms of mercury may be less toxic than that which was previously thought. Graham George and his colleagues note that mercury-based fillings (amalgams) have been used by dentists to repair teeth for over 100 years. In recent years, their use has become controversial because of concerns about exposure to potentially toxic mercury. Even so, mercury can potentially exist in several different chemical forms, each with a different toxicity. Scientists analyzed the surface of freshly prepared metal fillings and compared these with the surface of aged fillings (about 20 years old) from a dental clinic. Fresh fillings contained metallic mercury, which can be toxic. Aged fillings, on the other hand, usually contain a form of mercury, called beta-mercuric sulfide or metacinnabar. This form is unlikely … Read more

Common Bacteria Linked to MS

by

Research suggests that a common oral bacteria may increase autoimmune disease. Multiple sclerosis (MS) is a disease where the immune system attacks the brain and spinal cord. It currently affects nearly around 1 in 700 people in the United States. Patients with MS have a variety of neurological symptoms, including difficulty in moving, difficulty in speech, and muscle weakness. Porphyromas gingivalis, a common oral bacterium in humans, produces a unique type of lipid, phosphorylated dihydroceramides (DHCs), which enhance inflammatory responses. These lipids are also likely produced by bacteria found in other parts of the body including the gastrointestinal tract. Researchers led byFrank C. Nichols and Robert B. Clark of the University of Connecticut Health Center administered phosphorylated DHCs in a mouse model of MS to determine if these lipids cause immune-mediated damage in autoimmune disease. The severity of disease was … Read more

Obstructive Sleep Apnea and Bruxism

by

New research presented at CHEST 2009 found that nearly 1 in 4 patients with obstructive sleep apnea (mostly Caucasian men) suffers from nighttime teeth grinding. Eight percent of the general US population suffers from bruxism. “The relationship between obstructive sleep apnea and sleep bruxism is usually related to an arousal response. The ending of an apneic event may be accompanied by a number of mouth phenomena, such as snoring, gasps, mumbles, and teeth grinding,” said Shyam Subramanian, MD, FCCP, Baylor College of Medicine, Houston, TX. “Men typically have more severe sleep apnea, and perhaps may have more arousal responses, which may explain the higher prevalence of teeth grinding in men. Besides, men characteristically tend to report more symptoms of sleep apnea than women, such as snoring, loud grunting, and witnessed apneas.” Anxiety and caffeine use also help explain the relationship … Read more
