Silk and stem cells are being used to generate salivary glands

Source: biotechin.asia Author: Manish Muhuri Saliva is a watery substance secreted by the salivary glands located in the mouth. Saliva is essential for good health, as it assists in speaking, swallowing, food digestion, preventing oral infections in addition to many other tasks. Without normal salivary function the frequency of dental caries, gum disease (gingivitis), and other oral problems increases significantly. Location and types of salivary glands in humans. Image Courtesy : Wikimedia Commons Dysfunction or reduction in activity of salivary glands can be caused by many factors, including diabetes, radiation therapy for head and neck tumors, aging, medication side effects, and Sjögren’s syndrome. Sjogren’s is an autoimmune disease where the body attacks its own tear ducts and salivary glands. Patients suffering from this disease have severely dry mouth. No treatments are currently available for dry mouth. Salivary glands, unfortunately, have very little regenerative capacity. The title must have left you wondering about the correlation between silk and saliva – what do they have in common? They are both actually part of a unique experiment going on in San Antonio, a study that could change the lives of millions of people who suffer from dry mouth. Chih-Ko Yeh , BDS, Ph.D., and Xiao-Dong Chen, MD, MS, Ph.D., of the UT Health San Antonio School of Dentistry decided there had to be a better way to help people than try to develop drugs and figured that stem cells may help solve a common, painful problem. Yeh said the idea is [...]

Proper dental care for cancer patients: why it is important

Source: newcanaan.patch.com Author: Alan B. Sheiner DDS Common side effects from radiation therapy are not stressed enough in dental schools, but they can be managed and even prevented. A few weeks ago, I was contacted by a retired physician with whom I had not spoken for a number of years since he retired from practice to become a “gentleman farmer” in the country. While I was happy to hear from him, his news was not so good. He was calling because he had been treated for base of tongue cancer and his teeth were “coming apart”. His cancer treatment consisted of chemotherapy and radiation therapy. Unfortunately, he somehow “slipped through the cracks” and his oral cavity was now suffering from some of the side effects of the cancer therapy – fortunately he is currently cancer free. The oral cavity, one of the most complex and visible organ systems in the body, is invariably compromised as a result of treatment for head and neck cancer. Whether the malignancy is to be treated by surgery, radiation therapy, chemotherapy or a combination of these modalities, the function, if not also the form, of the oral cavity will be impacted. Aside from the obvious physical changes after cancer surgery to the head and neck region, there are issues which usually accompany radiation therapy to the head and neck region. There may be side effects from cancer therapy, some of which can be devastating, but preventable or manageable with proper precautions and care. The most [...]

Consistent evidence to support the use of xylitol- and sorbitol-containing chewing gum to prevent dental caries

Source: www.nature.com Author: Svante Twetman Question: Are polyol-containing chewing gums effective in reducing dental decay? Abstract Data Sources Studies were identified using searches with Medline, the Cochrane Library and Google Scholar. Study selection Studies were screened independently and were included if they evaluated the effect of one or more chewing gums containing at least one polyol (xylitol, sorbitol, mannitol or maltitol) on caries development, provided they supplied original data generated by means of a comparative design (experimental or observational) and were published in English. Studies were excluded if only an abstract was available or they described only the pharmacodynamic or pharmacokinetic properties of polyols or did not include a no-treatment arm in the study. Randomised trial quality was assessed using the Jadad scale, and the US Preventive Services Task Force criteria to grade the internal validity of individual nonrandomised studies. Data extraction and synthesis Data were extracted independently with only the final outcomes of a study being recorded. It was decided that surface rather than tooth level data would be recorded. Incremental caries was converted to prevented fraction (PF; the proportional reduction in dental caries in experimental groups relative to control groups) for meta-analysis. The studies were grouped according to type of polyol and a separate meta-analysis performed. Data were pooled using both a random and a fixed-effects model and heterogeneity assessed using I2. Results Of 231 articles identified 25 studies were initially selected with 19 being included in the review [six randomised controlled trials (RCT) of which four were [...]
