The Way To Stop Wisdom Teeth Growth In Kids Is Found

Wsidom teeth growthIt is a known fact that wisdom teeth cause lots of problems in many modern people. According to the estimations, every 9 of 10 people have various unwanted conditions related to their wisdom teeth. Some people suffer from impacted wisdom teeth, or improperly growing wisdom teeth which very often causes terrible pains and inability to use the teeth properly. As a result, those people are forced to visit dental clinics and get possible treatment, however, in most of such cases dental care specialists offer removing wisdom teeth. This is quite a serious surgical procedure linked to numerous risks, including the risks for infections and other serious complications.  The experts from the American Association of Oral and Maxillofacial Surgeons say that the number of wisdom teeth removal surgeries has been firmly increasing for a few last years, and it is hardly possible to find an effective solution to stop this tendency.

Some scientists were thinking about the strategies and looking for effective ways to stop wisdom teeth growth, thus receive an opportunity to help people avoid going through pains and painful dental procedures of wisdom teeth removal. Earlier this month, the findings of a very interesting relevant study were published. According to the conclusions of an expert group based in the Tufts University School of Dental Medicine paediatric dental clinic, it is possible to inhibit wisdom teeth growth in young children by giving them some type of dental anesthesia. As the experiments of the scientists have shown, this can be an effective approach to stopping the development of wisdom teeth and making young children not suffer from wisdom teeth related problems in the future. It is reported that the practical experiments involved working with 220 young children aged between 2 and 6, who came to the paedistric dental clinic for various sorts of dental treatment.

The kids had annual X-ray in the clinic for three and more years, and the scientists payed attention to the fact that those kids who were treated with local dental anesthesia (also known as numbing) during dental procedures to their low jaws had considerably higher incidence of underdeveloped or even missing low jaw wisdom teeth buds comparing to those participants who have never had dental anesthesia. According to Anthony Silvestri, one of the study leaders and a professor of prosthodontics and operative dentistry, “The incidence of missing wisdom teeth was significantly higher in the group that had received dental anaesthesia; statistical evidence suggests that this did not happen by chance alone.” He underlined that normally, wisdom teeth buds start developing in little kids aged between 2 and 4, and in late teenage hood wisdom teeth start already emerging. However, in some people wisdom teeth may start emerging in early adulthood, or even as late as in the late 20s – early 30s.

The scientists are convinced that the approach they have found will open a way to developing a new treatment allowing people avoid problems with their wisdom teeth by simple not developing them. However, it is underlined in the report that further more thorough studies are necessary in order to confirm the findings and develop a clear technology based on the findings. “Dentists have been giving local anaesthesia to children for nearly 100 years and may have been preventing wisdom teeth from forming without even knowing it,” the study leader said. “Our findings give hope that a procedure preventing [wisdom tooth] growth can be developed.” The report about this interesting research was recently published in the Journal of the American Dental Association. Many dental experts expressed their interest to these findings, though they failed to explain cause-and-effect links between using dental anesthesia and wisdom teeth growth inhibition. Hopefully, further studies will find the relationship very soon.

Stem Cells Treatment Can Soon Replace Common Dental Treatments

dental treatmentsMany people avoid visiting dental clinics and dental cabinets due to their huge fear of pain and discomfort linked to dental procedures. This dental phobia usually becomes a reason of more serious dental problems since those people who suffer from it tend to fight against tooth aches and other dental pains on their own, until the situation turns into something really serious, so it becomes impossible to avoid visiting dental specialist’s cabinet anymore. Such people look for new dental technologies without pain and unpleasant feelings, so they would never miss visiting dental care specialists and be able to prevent possible serious dental problems. It is a known fact that stem cells technologies can soon turn into a helping hand to those who suffer from dental phobias. According to the latest findings, this approach can give us the ways to forget about pains and other unpleasant feelings we experience when undergoing dental treatments.

Earlier this month, a group of Japanese specialists reported that they managed to use stem cells technology to totally restore tooth tissues of dogs. Therefore, the experts from Shin Nippon Biomedical Laboratories in Kagoshima and from the School of Dentistry at Aichi-gakuin University, are convinced that they are very close to developing similar kind of technology for people, and using stem cells it will soon be possible to forget about such common dental treatments as tooth filling, root canal, and many others. In modern dental clinics, tooth decay is treated by removing a piece of pulp and its surrounding, which is always accompanied with pain (unless a painkilling injection is used) and psychological discomfort, and replacing the removed part with various types of tooth filling. Sometimes, very serious side effects many take place.  ‘Dental cavities and inflammation of the surrounding pulp is a challenging public health issue, as tooth decay not only can cause a patient great pain but it also can lead to other serious health issues including heart disease,’ the study leader said.

Pulp is a very important part of our teeth. It is filled with sensors which give us an idea about what kind of meals we’re tasting (hot, cold, etc.), and also our tooth pulp reacts on the factors like pressure, etc. Tooth pulp is known as an excellent source of stem cells, and, as the Japanese researchers managed to find out, those stem cells can be used to regenerate various tooth tissues, this way helping to prevent the necessity of going through painful dental treatments. The experiments with dog teeth were successful, and the researchers managed to use tooth pulp for restoring not only pulp tissues, but the tissues of the whole tooth. For the experiment, pulp from the root canals of 18 dogs was taken, from which stem cells were collected, and then in the labs the stem cells were treated with what is known as granulocyte-colony stimulating factor (G-CSF). The results were received very fast, and to a great surprise of the scientists, it became possible to regenerate the whole tooth by using the stem cells in quite limited amount of time.

‘We also noted that the pulp stem cells treated with G-CSF yielded a significantly larger amount of regenerated dentin-pulp complex than those without it,’ the study leader, Dr. Nakashima, a specialist of the National Center for Geriatrics and Gerontology, said. The scientists did not manage to detect any evidence of toxicity or any other possible side effects of the technology. However, they are still concerned about the issues of safety, which, according to their comments, should be solved in order to proceed with the experiments and come to working with human teeth. The approval for new studies is expected to be granted soon by the Japanese Ministry of Health, Labour and Welfare. The detailed information about the study and newly proposed stem cell technology to replace common dental treatments can be found in one of the latest issues of the journal  STEM CELLS Translational Medicine.

Losing Teeth Is Often Linked To Memory Impairment In Aging People

Losing TeethAging is linked to many symptoms, and losing teeth is one of those. As we age, our dental health goes worse and worse, and eventually most of aging people lose their teeth, or suffer from other serious dental problems. Certainly, dental health of aging people differs, and most of people lose only some of their teeth by the age of 55-60. In any way, the scientists are convinced that there are strong links between losing teeth and having problems with brain function: in particular, suffering from memory impairment. Those are the findings of a recent study published by the expert from an international research group. The scientists the Institute of Clinical Dentistry in Tromsx, Norway, and from Umea University and Stockholm University in Sweden looked closer at possible connections between the number of teeth and memory function of a group of the participants.

The researchers invited for their study 275 participants, both male and female, aged between 55 and 80. After examining the current dental health condition of the participants, the scientists found out that all of them had at least 10 and at most 22 teeth less than 32, the normal amount of teeth in a healthy human mouth. At that, as it is reported, about 70 per cent of the lost teeth were molars. Then, participants were offered a series of memory tests. ‘In line with the stated hypothesis, the number of natural teeth was positively associated with performance on episodic memory, recall as well as recognition,’ it is stated in the report about the study which recently appeared in the online issue of the European Journal of Oral Sciences. Therefore, the first thing which became apparent to the scientists is that losing teeth is directly linked to memory impairment since those participants who had less teeth performed poorer in memory tests compared to those participants who had more of natural teeth.

Further analysis and processing the information have shown that the number of natural teeth preserved in the mouth of an aging person count for about 20 per cent of the variance in such concept as episodic recall of the events, for as much as 15 per cent in the variance of episodic recognition, and finally about the same share of the variance in semantic memory. It is interesting that after analyzing some additional materials, the scientists came up with the conclusion that replacing missing teeth with tooth implants can help reduce brain function damage and prevent memory impairment. Further studies allowed the researchers to formulate the hypothesis that losing teeth is linked to serious changes in the daily diet of aging people. As a result, considerably less amount of vitamins, minerals, and other essential nutrients can be found in their body systems and organs. Possibly, this very phenomena should play a role of trigger for memory impairment, increased risks for Alzheimer’s disease and other dementia like brain disorders.

Actually, it is underlined that the reported research is not the first one which found strict links and connections between poor dental health and increased risks of poor brain function or memory impairment. In particular, there is very strong evidence that poor dental health in the elderly, and especially suffering from gum disease, is a sign of approaching Alzheimer’s disease. It was found out that dental bacteria causing gum disease can spread around the whole body and is most likely cause brain inflammation, resulting in dysfunctions like Alzheimer’s disease and other dementia like brain disorders. In fact, one of the recent studies by an expert group from the University of California found out that a good dental health, a proper oral hygiene and great teeth condition is linked to reduced risks for Alzheimer’s disease. After collecting and analyzing the data on about 5,500 aging people, the scientists came to the conclusions that a proper dental health can help us reduce our risks for Alzheimer’s disease by almost 65 per cent.
