Stem Cells Can Help Fight Inflammatory Disease

A recent study shows that stem cells found in mouth tissue can help relieve inflammatory disease. The stem cells studied are gingival mesenchymal stem cells (GMSC) which are found in gum tissue in the mouth. Similarly to other types of stems cells, GMCS develop into cells that effect the immune system. The study found two differet types of GMSC: those that arise from the mesoderm layer of cells during embryonic development (M-GMSC) and those that come from cranial neural crest cells (N-GMSC).  The two types of stem cells vary substantially in their benefits. N-GMSC was found to be easier to change into other cells include neural and cartilage-producing cells. N-GMSC was found to have more of a healing effect on inflammatory disease. When the researchers transplanted N-GMSC into mice with dextrate sulfate sodium-induced colitis, which is an inflamed condition of the colon, it was found that the the inflammation was significantly reduced The bottom line from this study is that stem cells found in gum tissue may have important applications to aid in disease and with health. The stem cells in the gum tissue may able to help in improving skin wound healing and helping to reduce scar formation. Of […]

Bisphenol A Exposure in Early Age May Damage Enamel

Bisphenol A (BPA) is a chemical compound that is used to make up resins and plastics. For example, bisphenol A is used in bottles, inside drink cans, and inside food tins. Research has shown that bisphenol A has been found in human blood and urine hence indicting that it has been ingested. Other research has shown that bisphenol A has adverse effects on the development and reproduction of lab animals. Bisphenol A has already been banned from being used in the manufacturing process of baby bottles in Europe. A recent study set out to determine if teeth of rats when treated with low daily doses of bisphenol A are damaged. The researchers showed that the teeth of rats treated with low daily doses of bisphenol A are in fact damaged and that the characteristics present are similar to what has been found in a new pathology of tooth enamel in a small percentage of children between 6 and 8. Specifically the researchers showed that the teeth showed numerous characteristics that are common with a tooth enamel pathology known as Molar Incisor Hypomineralisation which selectively affects permanent incisors and first molars. Children who have this pathology present with teeth that are […]

The American Dental Association: Is it Patient-Centered, Science-Based and Ethically-driven?

Some time recently (within the past 6 months) the ADA (American Dental Association) has updated their about me page over at A new video appears and under it the text reads “This American Dental Association video tells our story and highlights how the ADA has always been a patient-centered, science-based and ethically-driven association. It captures the ADA’s spirit and what the ADA strives to be.” Viewing the video the words patient centered, science-based, and ethically-driven are repeated. The video also throws around the terms continuous learning, research and development, patents, and up to date. In one segment a dentist presumably says do no harm, always do good, treat people with fairness and honesty, and respect the doctor patient relationship. Unfortunately I disagree with the ADA’s assertion that they have always been patient-centered, science-based, and ethically-driven. As stated before on this website, see for example this blog post I was never made clear that wisdom teeth were no longer commonly removed in other countries prior to having my healthy wisdom teeth extracted in June of 2006. Guidelines from SIGN and NICE existed in 1999 and 2000 respectively see If the ADA was always a patient-centered, science-based and ethically-driven […]

Everything You Need to Know About Dental Implants

Dental Implants A dental implant is a replacement tooth that looks exactly like your real teeth. There is a root that is placed into the jawbone, which holds the replacement tooth in place. Dental implants are a perfect option for people who have lost teeth because of an injury, periodontal disease, or for any other reason. Types of Dental Implants There are two types of dental implants. The type of dental implant that you receive depends on what condition your mouth is in. The two types are Endosteal and Subperiosteal. Endosteal: This is the type of implant that is used most often, and is placed in the jawbone. Screws, blades, and cylinders are used to secure the teeth to the jawbone. Each of the implants holds one prosthetic tooth, and it is used as an alternative for patients with removable dentures or bridges. Subperiosteal: This type is placed under the gums and rests on top of the jawbone. They are most commonly used for people who have a shallow jawbone and do not want to have a procedure to rebuild the bone structure. Are Dental Implants Right for You? People who have good oral health are the perfect candidate for […]

Cheese may aid in cavity prevention

In an article appearing in the May/June 2013 issue of General Dentistry, it was found that eating cheese and other diary products may be beneficial in protecting teeth against cavities. The study sampled 68 subjects between the ages of 12 and 15 and looked at their dental plaque pH in their mouth before and after eating cheese, yogurt, and milk. In fact, three different groups were used one that eat cheddar cheese another that drink milk and another that eat sugar free yogurt. Each group was told to eat/drink for around 3 minutes and then swish their mouth with water. Then the researchers measured the pH level of each subject’s mouth at 10, 20 and 30 minutes after they finished eating/drinking. The researchers found that the groups who drank milk and ate yogurt had no changes in pH levels in their mouth. However, those who ate cheese showed a rapid increase in pH levels which was present for all 3 intervals looked at. This suggests that cheese has anti-cavity properties because a higher pH level puts a person at a less chance of developing cavities. The researchers are not entirely sure what caused the rise in pH levels from eating […]
