A team of researchers from Queen Mary's University in London today presented their new work devoted to the study of a new way of growing enamel on teeth – it is known that this is one of those types of hard tissues that cannot be restored on its own. On the contrary, with age, enamel undergoes significant changes, often wearing out under the influence of many harmful factors. And despite the traditional synthetic tools and approaches to the growth of enamel, today's study is devoted to the use of specialized nanocrystals, which start the process of restoration and spread of new enamel over the entire surface of the teeth.
At the moment, the most used enamel restoration technique is laser exposure at low frequencies, but even this modern approach has many drawbacks and side effects – including the uneven distribution of enamel on the teeth. A team of London researchers presented their study, which is based on the use of a special protein component, which, when decomposed on the surface of the teeth, forms special apatite nanocrystals that structurally resemble enamel.
The results of preliminary tests have already demonstrated that this nanocrystalline structure has a much higher degree of strength and resistance to external factors compared to conventional natural enamel, which is a promising research result.
However, experts note that they still have to conduct many tests and experiments around the presented method of coating the teeth. The synthetic structure of nanocrystals, although it closely resembles natural enamel, still has a lot of features and side effects that must be isolated and removed before such a technique appears on the dental market in the UK and in Europe as a whole.
