A team of scientists from the University of Pennsylvania claims that they managed to patch up permanent teeth in children with the help of stem cells taken from baby teeth.
The team performed the clinical trial that involved 30 children treated with the new method and 10 children treated with the traditional method. They suggest that in the future it will be possible to use this technique to repair dental injuries and fix dead teeth in adults.
Songtao Shi, one of the research team, says: “This treatment gives patients sensation back in their teeth. If you give them a warm or cold stimulation, they can feel it; they have living teeth again. So far we have follow-up data for two, two and a half, even three years, and have shown it’s a safe and effective therapy.”
Scientists from Queen Mary University of London have created a new material for dental fillings, which can treat tooth by itself. It can be inserted into teeth to repair and regenerate dentin – the hard, bone-like tissue that makes up the bulk of all teeth.
Professor Robert Hill told that innovative structure is a bioactive composite material on a glass base. It appears that after the dental filling is placed in the tooth cavity, minerals begin to be released, which form a tooth tissue, namely fluoride, calcium and phosphorus. According to this, dental tissue will be recovered.
Also, comparing to old tooth fillings, the new material leaves no gaps between filling and tooth, making impossible a bacterial growth under filling. At the same time scientists assure that this filling will be put once and forever. It will not be weared out over time, like modern tooth fillings, and certainly will not fall.
The technique just won second prize in the materials category of the UK Royal Society of Chemistry’s Emerging Technologies Competition 2016.
There is speculation that coffee, both with cigarettes and tea darken teeth, the enamel covers with yellow coating.
But recent research have shown that this is not true.
In order to protect your teeth from the adverse effects, it is necessary to observe basic rules.
Dentists say that the teeth and coffee – is a healthy union. When coffee is used tooth enamel may change its color, only if it contains microcracks. In this case, you need to follow simple rules of hygiene, and the darkening should not scare you.
Do not drink sweet coffee. This will help to protect your teeth from the accumulation of bacteria and intensify the taste of the other way, and you’ll discover a new flavor. Sweet drink can trigger the accumulation of pathogenic bacteria, which cause yellowish plaque.
Everybody knows that sudden temperature changes are bad for teeth, but we like to enjoy a coffee with ice cream. The combination of hot-cold things forms microcracks, and subsequently darkening of the tooth enamel.
Recently the entire world heard the news that coffee prevents the formation of tooth decay. Italian scientists as a result of deep research, came to the conclusion that such a beverage like coffee, has antibacterial properties that harmful bacteria do not stay on the surface of the teeth.
The US study also found that coffee have acids, which do not allow the formation of bacteria that form tooth decay. But of course we have in mind, coffee without sugar, snacks and cream. Still there is an interesting fact, people who regularly drink coffee are protected against cancers of the mouth and throat of about 40%.
If you follow all the advice, you can enjoy a delicious drink, as well as the impact it has on the body.
