The restoration procedure the group of Missouri S & T researchers has patented allows oral surgeons to computerize the creation of a dental bar, often referred to as an over-denture. The dental bar is a device oral surgeons use to connect implanted teeth to dentures, and prior to the computerized procedure required a labor-intensive process of molding the patient’s teeth and creating a cast from which the dental bar could be created.

The new computerized process, developed by Missouri S & T distinguished professor Dr. Ming Leu and one of his grad students, Amit Gawate, may revolutionize the way dental bars are created. “This method can reduce the cost as well as the time involved,” Leu says. “The process uses less material than machining or other processes and can be easily tailored,” he added. The process works by taking an image of the patient’s mouth and using special algorithms to design a computerized model of the dental bar.

This is not Leu’s first contribution to the advancement of dentistry. A manufacturing expert, Leu previously was able to develop a process that allowed prototypes of dental prosthetics out of ice using an approach he calls “rapid freeze prototyping.” That invention garnered Leu a grant from the National Science Foundation, which in turn led to the development of the recently patented computerized dental bar process.

While receding gums are often visible, another way to tell if the gum line is receding is to feel for a notch at the gum line, which can indicate that gums are receding. While gums that are receding are usually a typical part of growing older, many people may notice them much earlier than is normal.

Underlying causes of receding gum lines should be addressed by the dentist; misaligned teeth can be straightened and plaque can be removed. Treating the gum itself may require taking grafts from other parts of the mouth. However, rather than replacing gum tissue, many dentists opt to simply prevent the gum from receding further by drilling the teeth and filling them with a special material that helps reduce the risk of further gum loss.

There is a second treatment option being considered for approval by the American Dental Association (ADA) that would offer a less invasive solution. The treatment would allow dentists to simply roughen the surface of the tooth instead of drilling into the tooth before applying a thin coat of the material that helps prevent gum loss. The teeth are then “cured” under a special light before a second coat is treated.

Treating receding gums is critical to tooth health. When gums recede, more sensitive areas of the tooth are exposed. The risk of tooth loss and tooth decay is also increased. To prevent receding gum lines, dentists recommend daily flossing.

In order to get a proper fit, a dentist is required to file the existing teeth to make space for the veneer. Even though porcelain veneers provide many benefits, they are not considered to be an inexpensive remedy to misaligned teeth. The cost of porcelain veneers varies greatly depending on local market rates, the quality of the veneer, and sometimes the experience of the dentist.

Although the cost of porcelain veneers in most places remains around $1500 per porcelain veneer, there could be great differences in pricing. Minimum charges are usually seen around the $500 mark to up to $3000 per veneer on the higher end. The life span of a veneer is usually around 10 years with the ability to last longer if maintained properly.

What can you expect at the dentist’s office? After taking an impression of your tooth, a lab is contacted to fabricate the veneer for custom fitting. You can expect multiple visits to fit your veneer and high quality work results in a perfect fit the first time around.

The easiest way to choose the right place for you to get a porcelain veneer is to look around your local area and get references! Better yet, if you already have a dentist you trust, get in touch with him or her to ask every question you may have about a possible veneer fitting. Don’t be shy about asking for a break in the price as this market is quite competitive.

Recently, lead researcher K. Tezuka and researchers N. Tamaoki, H. Aoki, T. Takeda-Kawaguchi, K. Iida, T. Kunisada and T. Shibata from the Gifu University Graduate School of Medicine in Japan, as well as K. Takahashi, T. Tanaka and S. Yamanaka, all from Kyoto University, Japan, discovered a new way to collect stem cells: from tooth pulp.

The researchers were able to create conditions that caused human cells from the pulp of the tooth to be reprogrammed as pluripotent stem (iPS) cells. These somatic cells can be easily removed from extracted teeth, converted to iPS stem cells, and stored in stem cell banks for research and application use. The most exciting part of the group’s research revealed that dental pulp is actually an optimum source of iPS cells and that the cells would be a perfect match for nearly a fifth of the population.

This research provides a new avenue for stem cell researchers around the country to gather the material they need to conduct regenerative experiments with stem cells without facing the level of controversy they had been. Because the work advances the ability of scientists to force any adult somatic cell into a stem cell state, it will be easier to treat patients without the concern of rejection, since their own tissue could be used.

Apart from its usual uses, crown can also be used to hold together a broken tooth and a bridge. Not only in physical deformities, dental crowns can also be used to hide discoloration of teeth. When applied, a crown fully covers the teeth above the gums. One of the basic reasons of getting a crown is that the filling material cannot be used to make a complete tooth structure and is not that strong enough.

Usually, for getting a crown you would have to make at least two visits to the dentist. During the first visit, the dentist will take the impression of the tooth and send it to dental laboratory for getting molded. You may get a temporary crown until the time your crown arrives from the dental laboratory. Prefabricated crowns are usually used as a mean for temporary restoration. Crowns are usually made from metal, porcelain, porcelain with metal and ceramic materials.

There is a variety of metals that can be used to make crowns some of them are, gold alloy, palladium alloy or other base metals like nickel or chromium alloy. Although crowns are usually considered very strong and durable, metal and Porcelain fused metal material is the strongest and is mainly used for molars. Because of the higher durability and tougher strength of crown materials, crowns are known to have last for seven to eleven years, although with proper care and maintenance they can last longer.

Even though most of the teeth that require crowns are usually decayed or damaged, a root canal is mandatory most of the times for such teeth. A crown is placed on the tooth only after proper space has been made for it. For doing this, a dentist may resort to filing of teeth to make gap for it. Then, the impression of the tooth is taken after pushing the gum down with the help of a thread or a cord. The impression is taken out and sent to a dental lab which sends the crown back after 2 to 3 weeks. After the crown comes, it is applied to the deformed or damaged teeth with the help of dental cement.

One should be able to carry on with the usual life’s work after having a crown fitted. If you are having any discomfort while chewing, there might be a problem with the fitting of the crown. Such problems usually occur when the crown and the tooth have a gap between them. A dentist would easily be able to remove such defects. Although not usual, sometimes the crown comes out completely, in such a case, call the dentist and fix an appointment after cleaning and keeping the crown in a safe place so that it is not damaged.

Those Americans over the age of 65 who qualify for Medicare have health coverage, but that coverage also does not cover dental, adding another 90 million to list of those who have no dental insurance. Unfortunately, untreated dental care problems can end up costing much more because of the complications they cause in a person’s physical health. Gum disease is one of the leading risk factors in developing heart disease and type II diabetes.

The CDC also reported a significant race disparity when it came to dental coverage. Of those without coverage, nearly 40 percent had not graduated from high school. Non-Hispanic African Americans were more likely to be without dental insurance that non-Hispanic white, Asian, and Hispanics. This disparity affects children the most; nearly a quarter of all children are without the dental care they need, and the highest number of untreated children are African American.

Dental care professionals have expressed concern that the lack of available dental care may lead to a more severe health crisis because of the complications that can arise from not having regular care. They are encouraging every individual to take an aggressive approach to home dental care by brushing and flossing twice a day and using a fluoridated cavity rinse.

The VA sent letters to more than 1,800 veterans who had received dental care at the clinic over the past 8 months, notifying the vets that they should make an appointment in order to have their blood tested for Hepatitis and HIV. So far, three of the treated vets have tested positive for Hepatitis, although none have tested positive for HIV so far. According to the investigation by health officials, it is suspected that employees at the Veteran’s Association clinic were reusing disposable dental tools that were only designed for one-time use. The cross-contamination that occurred placed a large number of veterans at risk over a prolonged period.

In response to the outbreak and the poor sterilization practices in place at the clinic, health officials are calling for all dental clinics in the country to implement improved sterilization procedures. They are being reminded as well that one-time use instruments must be disposed of properly after the single use on one patient and not reused with additional patients. The health officials are also asking dental providers to switch to one-time use gloves and masks to prevent the spread of germs.

Scientists measured maximal oxygen consumption or VO2max to identify subjects with the highest levels of physical fitness. Weight management was assessed by measuring both body mass index or BMI and percent of body fat. Researchers also conducted a periodontal exam to assess the level of gum disease present in each patient.

Being overweight is associated with an increased risk of heart disease, some cancers and diabetes. Now, it appears to be a risk factor for severe peritonitis, as well. Peridontitis, also called gum disease, has been associated with heart disease, rheumatoid arthritis and diabetes.

According to Professor Samuel Low of the University of Florida, research shows that overall health is connected with periodontal health. This study should motivate patients to watch their weight and exercise regularly, and strenuously.

Severe gum disease can be prevented by brushing and flossing daily, and visiting the dentist at least twice per year. Anyone with signs of bleeding gums, inflammation or gum tenderness should see a periodontist, a specialist in gum disease. Gum disease is the leading cause of tooth loss among adults. Inflammation of the gums has been linked with other inflammatory diseases including arthritis.

Because the study was not randomized, it is impossible to draw conclusions about cause and effect. Researchers can simply say that individuals who are very fit and have a normal body weight are less inclined to have severe periodontal disease.

A genetically engineered cold-sore virus offers new hope for patients with mouth, neck and head cancers.

The herpes virus, Onco VEX, proved effective in a small clinical trial at the Institute of Cancer Research in the U.K. Seventeen patients had the virus injected into their lymph nodes, in addition to treatment with radiation and chemotherapy.

The Onco VEX virus has been genetically modified to invade both healthy and cancer cells. Once inside, the modified virus multiplies only in the cancer cells. It then bursts, killing the tumor cells and releasing a protein that stimulates the patient’s immune system.

Fourteen of the 17 patients showed reduction in the size of the tumors. The lymph nodes were removed as a precaution, but showed no residual cancer in 75% of the patients. The two-year survival rate for the patients was 76.47%. The typical relapse rate is 35 percent to 55 percent, but in this case only 23.5 percent of the patients relapsed.

Principal researcher Dr. Kevin Harrington calls the results “very favorable.” He adds that despite the small study size, the results are good enough to warrant a much more extensive test of the virus.

Patients in the study experienced mild to moderate side effects, some of which have been attributed to chemo and radiation. However, some patients did experience fatigue and fever that appeared to be related to the virus.

This is especially good news since researchers recently reported that younger people are being diagnoses with oral cancer, which seems to be on the increase in Britain and other developed nations. Risk factors for oral cancer include smoking and drinking.

Early diagnosis of oral cancer improves the odds of survival from 50 percent to 90 percent. New treatments could increase the odds even more.

The Notch signaling pathway is one of the most basic cellular development signals within the body, directing cells during fetal development to take on the specific roles for which they have been enabled. It’s long been known by scientists that the Notch pathway affects the development of organs in the body, but Mitsiadis has discovered that this same pathway directs the development of healthy teeth through the activation of the Jagged2 gene.

The usefulness of Mitsiadis’s research extends beyond simple genetic understanding. Using stem cells, understanding the way the Notch signaling pathway and the Jagged2 gene work, scientists will eventually be able to revolutionize dental care, including repairing teeth with genetically created tooth material and even creating an entire set of “bio teeth” using stem cells. Mitsiadis explains: “A combination of stem cells with an artificial scaffold could constitute a solution.” This research is the first step toward an entirely new approach to dentistry that would allow tooth regeneration by creating teeth that has the right shape and size for the person for whom they are created, made of real tooth material instead of a synthetic denture.
