Obstructive Sleep Apnea and Bruxism

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 between sleep apnea and teeth grinding. Through a retrospective chart review, Dr. Subramanian assessed the prevalence of bruxism and gastroesophageal reflux (GERD) in 150 men and women. Each group consisted of 50 Caucasians, 50 African-Americans, and 50 Hispanics. Results showed that 25.6 percent of patients suffered from teeth grinding, while 35 percent of all patients with OSA complained of nocturnal […]

Dental Stem Cells Generate New Bone Tissue

An interesting article presented in Genetic Engineering and Biotechnology News discusses dental stem cells and their role of creating new bone tissue in humans. This article is based off of the procedure and results in a recent paper titled “Human Mandible Bone Defect Repair by Grafting of Dental Pulp Stem/Progenitor Cells and Collagen Sponge Biocomplexes” which has been conducted by Gianpoalo Paccio and his partners in Naples, Italy. (Europen Cells and Materials Vol.18, 2009, pages 75-83). Seventeen patients had their wisdom teeth extracted and the dental pulp stem/progenitor cells known as DPCs were eventually used to fill the injury site left by the wisdom teeth that were removed. Three months later, the patients were examined by X-ray. The sites where the wisdom teeth were extracted and filled with the DPCs (along with a collagen sponge scaffold) showed complete regeneration of the bone. This shows that dental stem cells have a wide array of potential and possibilities for the future. If you are considering having your wisdom teeth extracted even after knowing the complications, risks, and benefits, you may also want to consider having your stem cells saved. Several companies have emerged  to help you store your stem cells from your […]

Near Death Wisdom Teeth Removal Experience

I wanted to alert everyone to a recent article in The Orangeville Banner and The Wellington Advertiser regarding 17 year old female Mercedes Moore and her wisdom teeth removal near death experience. According to the articles, Mercedes had her wisdom teeth removed in February, 2009. She began to feel a purple lump on her left temple along with pain and swelling. She saw the dentist for a follow up and told her he thought nothing was out of the ordinary. Eventually she had to be airlifted to a hospital because she was suffering from septic shock due to an infection that had developed and spread to her main arteries and organs. She had to undergo a surgery on her brain to remove a piece of skull and clean the infection. This surgery lasted 10 hours. Due to the blood clotting she suffered from several strokes and remained in the hospital until May, 2009, a period of around 11 weeks. She then remained in a rehabilitation center until October, 2009. She is now partially paralyzed in her right arm and leg and can only walk short distances. She is also learning to talk again and continuing to undergo physical therapy, occupational […]

Continue Reading 3 – Ira Shapira

Recently launched is a new website This website is run by Dr. Ira Shapira a dentist in Gurnee, Illinois.  People should take CAUTION when viewing this site. First, the site serves as a promotion tool for Dr. Ira Shapira and other neuromuscular dentists in the U.S. Of course, since Dr. Ira Shapira is located in Illinois his practice is the only one listed when you select you live in IL. Currently the site only has one or two dentists at the most for different states. Some states such as Florida currently have no “doctor’s” listed. Secondly, the site is attempting to aid in the dentists ‘cashing’ in on the headache epidemic. In a press release by Dr. Ira Shapira he addresses a article in Medical Hypothesis (2009) “Migraine, neuropathic pain and nociceptive pain: Towards a unifying concept.“ This article can be found for your convenience at In the summary of the article it states “… we suggest that fundamentally all the three pain syndromes referred to in the article share a common pathophysiological mechanism, namely peripheral pain perception, peripheral sensitization at dorsal root ganglion or its intracranial counterpart (like trigeminal ganglion) and central sensitization at the spinal cord […]

Dental Sources of Information

If you are looking for dental information online there are several great sources of information to read. First, thanks for stopping by here at If you are looking for great information from a dentist online,  I would highly recommend Dr. David Leader. He frequently writes articles (usually at least once a month).  You can view his articles over at Some of the more recent article titles include “What Causes Cavities,” “Oral Surgery – Before and After,” and “Reasons to Call your Dentist.” Another source of dental information is the ADA (American Dental Association) News Today. They have many updated articles on dentists and various dental programs throughout the country. You can visit ADA News Today at There are many other websites and blogs that provide useful and informative dental information. Many have been covered before on this blog and site.
