Taste Genes Can Predict Tooth Decay

Posted in Dental News by UK Dental Tourism on September 30, 2010

Dental caries is a highly prevalent disease that is disproportionately distributed in the population. Caries occurrence and progression is known to be influenced by a complex interplay of both environmental and genetic factors, with numerous contributing factors having been identified including bacterial flora, dietary habits, fluoride exposure, oral hygiene, salivary flow, salivary composition, and tooth structure. Previous reports have characterized the influence of the genetic variation on taste preferences and dietary habits.

In an article published in the Journal of Dental Research titled “Taste Genes Associated with Dental Caries” lead researcher Steven Wendell and researchers Melissa Brown, Margaret Cooper, Rebecca DeSensi, Mary Marazita, Xiaojing Wang and Robert Weyant, all from the University of Pittsburgh; and Richard Crout and Daniel McNeil from West Virginia University, hypothesized that genetic variation in taste pathway genes (TAS2R38, TAS1R2, GNAT3) may be associated with dental caries risk and/or protection.

In this study, families were recruited by the Center for Oral Health Research in Appalachia (COHRA) for collection of biological samples, demographic data and clinical assessment of oral health including caries scores. Multiple single nucleotide polymorphism (SNP) assays for each gene were performed and analyzed using transmission disequilibrium test (TDT) analysis (FBAT software) for three dentition groups: primary, mixed, and permanent. Statistically significant associations were seen in TAS2R38 and TAS1R2 for caries risk and/or protection.

“This work is significant in that it identifies key genes that may explain the susceptibilities of some patients to tooth decay,” said JDR Editor-in-Chief William Giannobile. “Although an early study, this breakthrough on taste pathways and genes demonstrates how patient preferences that are genetically predetermined may put patients at risk for disease.”ScienceDaily

Treatment of Temporomandibular Joint Disorder ( TMD )

Posted in Oral Surgery by UK Dental Tourism on September 24, 2010

TMD, also commonly known as TMJD, is short for temporomandibular disorder and is a condition that affects the jaw, muscles in the neck and head and the TMJ joints next to each ear. The TMJ joint is responsible for coordinating movements that lead to eating, drinking and talking so any complaint in the area can have a significant impact on the life of the patient.

The main symptom of TMJ is unfortunately pain. This usually occurs when the patient is chewing or yawning, or any other extended movement of the TM joint. There may also be a painful ringing or tinnitus in the ear. Other major symptoms include swelling around the joint, a change in the bite and profile and trouble swallowing.In TMJ disorders, the joint can be affected by injury, arthritis, general wear and tear or degenerative joint disease. The disk of cartilage that cushions the joint can also become damaged or displaced, leading to a loss of flexibility or range of motion for the joint. Patients often experience pain, difficulty opening and closing their jaw or even hear a “clicking” or “popping” sound when using the joint.

One of the major problems when diagnosing TMJ is that a lot of these symptoms can be caused by manifold other conditions, some of which are far more likely to occur. This means that TMJ is often far down the list of diagnoses. Your dentist, if suspects TMJ, will conduct something called a clench test. This involves clenching the jaw to assess whether there is a structural disorder that could be TMd.

In most cases, treatment of TMJ will involve some level of orthodontics. In some severe cases, there may be a need for surgery but most bite misalignments can be cured with orthodontic treatment. During treatment, it may be necessary to wear a mouth guard to protect the lower teeth.

Symptoms can be treated with anti-inflammatory medications, bite splints or physical therapy techniques. But for patients with lasting TMJ pain, a consultation with an oral maxillofacial surgeon or a TMJ/oro-facial pain specialist can bring them more options to ease their condition.

The most minimally invasive technique for TMJ surgery is arthrocentesis, a short procedure usually performed under IV sedation or general anesthesia. Surgeons inject the joint with local anesthetic and fluid to flush out inflamed fluids.
Arthrocentesis is effective when inflammation is limited to or focused most within the joint.

When treatment requires open surgery, or arthroplasty, surgeons have several options, including disk repositioning, discectomy and joint replacement. Because these surgeries involve more risk, including damage to the ear canal or nearby nerves, they are only used after other treatment options have been considered.

Disk repositioning: Disk repositioning is used when the cartilage disk has slipped out of place inside the joint. Once out of place, the slipped disk can cause the often noted “popping” noise inside the joint, pinch a nerve surrounding the joint or stretch or inflame the surrounding ligaments. In disk repositioning, the surgeon makes an incision, moves the displaced disk back to its original position and stitches it in place, repairing surrounding ligaments if needed. Repositioned disks can sometimes slip back or degenerate.

Discectomy: A discectomy is a full removal of the disk in the TMJ joint. Disks that are constantly out of position or pop back and forth inside the joint are good candidates for this surgery.

Articular eminance recontouring: For some patients, the articular eminence (the “socket” part of the TMJ’s ball and socket joint) can be too deep. In this treatment, the surgeon shortens and smooths the articular eminence to prevent excessive forces on the joint, improve range of motion and reduce pain.

TMJ replacement: Newer techniques and materials have made prosthetic replacement of the TMJ a feasible option for patients with end-stage TMJ degeneration. The replacements have a socket component made of dense polymer and a jaw joint head made of a mixed alloy material that is attached to the remaining jaw bone. Prostheses are recommended to be replaced every decade.

There are various other treatments your dentist will be able to explain upon diagnosis of TMJ. If your jaw joints hurt or are swollen, then contact a dentist and ask for a test for TMJ.

SLActive – New Chemically-Modified Surface For Titanium Implants

Posted in Dental Implants by UK Dental Tourism on September 20, 2010

Dental implants have offered a successful way to restore teeth for more than 20 years. New challenges for improving the process include shortening the time to restore functionality and meeting aesthetic demands. Altering implant surfaces to help promote bone integration is one solution. SLActive, a new chemically-modified surface for titanium, the standard material of which implants are constructed, has shown positive results in this area.

An article in the August issue of the Journal of Oral Implantology reports a 98.2% success rate for SLActive at dental patients’ one-year follow-up. A noninterventional study was conducted to compare these results with previous findings of high survival and success rates among the same type of implants in a controlled clinical trial.

In this noninterventional study, results were obtained under common dental practice conditions where patient selection was not restrictive and technique was not controlled. Thirty dental clinics in Italy participated, and 226 patients were treated. Patients presented with a variety of risk factors, and both early (48 hours to 3 months) and traditional (3 to 6 months) loading of the implant was performed.

Osseointegration-the connection between living bone and artificial implant-can determine stability of the implant over time. Surface properties of the titanium implant, such as topography and roughness, can assist the chemical and biological interface that occurs in the early stages of healing and thus influence the long-term outcome.

The 98.2% success rate of this study was similar to that reported in formal clinical trials. The high success rate in both studies shows that the SLActive implant surface can be safely used with consistent, predictable results. Patients can expect integration of their implants that restores functionality for chewing and speech as well as aesthetics.

Making Stem Cells From Wisdom Teeth

Posted in Dental News by UK Dental Tourism on September 17, 2010

For most people, wisdom teeth are not much more than an annoyance that eventually needs to be removed. However, a new study appearing in the Sept. 17 Journal of Biological Chemistry shows that wisdom teeth contain a valuable reservoir of tissue for the creation of stem cells; thus, everyone might be carrying around his or her own personal stem-cell repository should he or she ever need some.

Groundbreaking research back in 2006 revealed that inducing the activity of four genes in adult cells could “reprogram” them back into a stem-cell-like state; biologically, these induced-pluripotent stem cells are virtually identical to embryonic stem cells, opening up a new potential avenue for stem-cell therapy whereby patients could be treated with their own stem cells.

However, despite their promise, making iPS cells is not easy; the reprogramming efficiencies are very low and vary among the cells that can be used for iPS generation and thus require good amount of “starter” cells — which might involve difficult extraction from body tissue (unfortunately skin cells, the easiest to acquire, show very low reprogramming efficiency).

Now, a team of scientists at Japan’s National Institute of Advanced Industrial Science and Technology may have found an ideal source: third molars, commonly known as wisdom teeth.

The soft pulp inside of teeth contains a population of cells known as mesenchymal stromal cells that are similar to cells found in bone marrow, a common stem-cell source. However, unlike bone marrow, tooth pulp is more easily obtained, especially in wisdom teeth, which most individuals have removed anyway.

The researchers, led by Hajime Ohgushi, collected tooth samples from three donors and managed to generate a series of iPS cell lines following the similar procedure of activating three key genes (however, in another beneficial change they did not have activate the c-MYC gene which might lead the cells to become cancerous).

The different cell lines displayed varying degrees of robustness but in some cases proliferated quite well, up to 100 times more efficiently than typical skin-cell-derived iPS cells. The molar-derived cells also could differentiate into many other cell types including beating cardiomyocytes (see an attached movie), as expected.

The presence of a supply of MSCs in wisdom teeth could have meaningful therapeutic ramifications. As noted by the researchers and others, wisdom tooth extraction is a common medical procedure in developed nations and, thus, creates a perfect opportunity to remove biological material in a sterilized setting; the teeth subsequently can be frozen and stored for many years until needed. In the meantime, that also provides time for researchers to better understand the details of iPS creation to further increase the efficiency for clinical use. Source : ScienceDaily (Sep. 10, 2010)

Secure Dentures With Mini Implants

Posted in Dental Implants by UK Dental Tourism on September 15, 2010

Nobody wants to lose their teeth but sometimes it happens either because of poor dental hygiene, accident or just as the result of age. When all or most of teeth have been lost it can often feel like there is little or no hope and can leave patients feeling quite despondent about the state of their teeth and smile. Lost teeth can also have a physical impact on the profile and structure on the face as the teeth act as a rigid support for facial tissue.

However, there are ways to replace missing teeth and with modern technology they are constantly improving in both functionality and appearance. Dentures have had a bad reputation in the past because they looked unrealistic and were also prone to falling out. Modern dentures however, are much better fitting and shouldn’t even need denture adhesive to keep them in place. Although many patients are opting to have mini-implants fitted to keep the dentures securely in place. These are small titanium screws that are anchored directly into the jawbone and can be used to clip dentures in place and hold them.

Modern dentures also allow much greater freedom to patients as they are capable of eating much more varied food and even things like apples present few problems. Our dentists will be able to give you a lot more information about the possibilities of modern dentures.

A well-made set of dentures should fit snugly around the gum tissue, using suction alone to remain in place. They should cause little or no irritation and be hardly noticeable when in the mouth. If your dentures are causing you problems then you need to make an appointment to have them sorted out.Ask your dentist to provide you with more information about how dental implants work and if you could be a suitable candidate.

Today, September 12th Is World Oral Health Day

Posted in Dental News by UK Dental Tourism on September 12, 2010

The American Dental Association (ADA) joins with the FDI World Dental Federation, the worldwide voice of the dental profession, in observance of the annual “World Oral Health Day” Sept.12. The purpose of this day is to increase global awareness for oral health, as well as the impact of oral diseases on general health and well-being.

The date marks the anniversary of the FDI World Dental Federation and their groundbreaking International Conference on Primary Health Care, which was held on September 12, 1978. In addition the date honors Dr. Charles Godon, the FDI founder, who was born Sept. 12, 1854.According to the FDI, Sept. 12 was chosen to coincide with existing oral health days around the world, to honor the FDI founder, Dr. Charles Godon, who was born on Sept.12, 1854, and to jointly celebrate the anniversary of the groundbreaking World Health Organization’s International Conference on Primary Health Care at Alma Ata, Kazakhstan , taking place on Sept. 12, 1978.

Throughout the world, dental caries or tooth decay is the most common chronic disease, particularly affecting children and disadvantaged populations. Dental disease results in unnecessary pain and suffering, and missed work or school days. Periodontal or gum diseases have been associated with diabetes, adverse pregnancy outcomes and other systemic ailments. Untreated tooth decay seriously affects a person’s quality of life.

Each and every one of us, as dentists and citizens, as professional associations and public health advocates, are able to contribute to better oral health worldwide. Let us on this  World Oral Health Day join together to recognise that oral health is a vital part of wellbeing for all, celebrate the progress we have made to date, but at the same time commit ourselves to continue working towards better oral health for all.

New Approach For Treating Tooth Hypersensitivity

Posted in Dental News by UK Dental Tourism on September 9, 2010

Recently NYU College of Dentistry researchers have identified a promising new approach for treating tooth hypersensitivity, while simultaneously preventing bacteria from causing further harm. Most toothpastes, protective strips and other treatments for tooth hypersensitivity utilize potassium oxalate to close the tubules. However, potassium oxalate cannot prevent a recurrence of tooth hypersensitivity because it is highly susceptible to the effects of acids in tartar, plaque, citrus drinks and other liquids.

In the NYU dental study, a coating made from fluoride and zinc ions in a calcium-phosphate matrix proved effective in reversing damage to the tubules caused by Streptococcus mutans, a bacterium commonly associated with tooth decay. The coating not only caused the exposed tubules to close again, but also prevented Streptococcus mutans from causing further damage.

Co-prinicipal investigators Dr Racquel Z. LeGeros, Professor and Associate Chair of Biomaterials & Biomimetics at the NYU College of Dentistry, and Dr Haijin Gu, Chief Dentist at Sun-yat-sen University Guanghua School of Stomatology in Guangzhuo, China, compared two groups of dentin samples immersed for 24 hours in a solution containing Streptococcus mutans. One group was treated with the calcium-phosphate/fluoride/zinc formulation for eight minutes, while the second group received no treatment. Bacteria multiplied on the untreated samples, but their growth and development was inhibited on the treated dentin. In addition, the treated group had significantly fewer open tubules than the untreated one.

“Because the calcium, phosphate, and fluoride ions formed a solution that occluded the open dentin tubules, and the zinc ions inhibited bacterial growth and colonization, our findings suggest that this formulation may represent a tooth hypersensitivity treatment that is less susceptible to the effects of acid than treatments made with potassium oxalate,” said Dr LeGeros, who plans additional testing to confirm the findings.

Tooth hypersensitivity occurs when the dentin, which lies just below the surface of the tooth, becomes exposed, causing tubules―tiny structures that transmit stimuli to the tooth nerve―to open up. When open tubules come in contact with cold, hot, sweet, or acidic substances, painful stimuli are transmitted to the tooth nerve. Typically, hypersensitivity is caused by oral bacteria, which attach to the tooth surface and leave an acidic residue of tartar and plaque.

Bright Smile with Zoom Whitening

imagesCA74N4MCZoom teeth whitening  is one of the most up to date whitening products on the market, using a special power lamp to activate treatment for speedier results. Zoom works like most other tooth whitening treatments by applying an active gel to the surface of the teeth to bleach any discoloured areas.

Teeth whitening is a very popular cosmetic dentistry treatment that can really improve the appearance of discoloured and stained teeth. Teeth become stained over time because of foods that we eat and other lifestyle choices. Substances that are particularly bad for the teeth are red wine, coffee and tobacco. These can leave teeth yellow or brown spoiling the appearance of a smile making you seem older. Teeth naturally discolour as we age, so any premature discolouration will have the effect of adding years to your appearance as well as looking unhealthy.

Teeth whitening using Zoom can restore the appearance of discoloured teeth, making the teeth look cleaner and healthier and giving you the confidence that comes from a beautiful smile. Your dentist will apply the gel in specially designed trays so that it is in close contact with the teeth. They will also use any necessary safety equipment to keep the soft tissue of the gums and tongue safe.

Some patients may experience some slight sensitivity after treatment but apart from this the process is completely painless. Some patients will notice results immediately but others may require a few treatments, depending on the individual’s teeth. Teeth whitening is one of the most effective and affordable cosmetic dentistry treatments so ask your dentist what it could do for your teeth.For more information call us at 07974-106163



Discover More About Braces At Shimla dentist

untitled1Braces can often be a very scary prospect for a teenager. The adolescent years are very difficult at the best of times so anything that can make you stand out from the crowd or attract negative attention can be very traumatic. This was often the case with the old style metal braces, which, let’s be honest, were hardly the most conspicuous of designs.

Thankfully, over the past ten years or so, a number of new orthodontic treatments have sprung up offering patients an alternative to wearing fixed braces. This has included the Inman aligner with its super-fast results, and Six Month Smile braces with their tooth coloured wires and brackets. However, one treatment stands out as the most efficient when it comes to discreet treatment.

Invisalign braces are made from one-millimetre thick clear plastic, which is almost impossible to see when in the mouth. This means that it is now possible to have your teeth straightened without anybody ever knowing. Not only is this a bonus for younger patients but also for older, professional patients who want to have straighter teeth without having to face the stigma of wearing braces in the workplace.

Not only are the Invisalign braces discreet, they are also fast-acting, with treatment being on average six-months shorter than with traditional braces. The Invisalign system uses a series of removable retainer braces over the course of the treatment each making a slight adjustment to the teeth. In all about twenty-five retainers are needed but this can vary according to individual needs. The fact that they are removable also means that the teeth are easier to clean and that they can be taken out for important occasions and sport. Call us for more information – 07974-106163
