Bacterium goes from the mouth to the heart to cause disease

The human mouth can have more than 700 different species of bacteria. Under normal circumstances these microbes co-exist as part of our resident oral microbiota but when they spread to other tissues via the blood stream, the results can be catastrophic. Researchers from the University of Bristol have revealed a potentially key molecular process that occurs in the case of infective endocarditis, a type of cardiovascular disease in which bacteria cause unwanted blood clots to form on heart valves. If untreated, this condition is fatal and even with treatment, mortality rates are high. There are over 2,000 cases of infective endocarditis in the United Kingdom (UK) annually and the amount is rising. The research involved the use of the UK national synchrotron facility, Diamond Light Source. Using this giant X-ray microscope the team was able to visualise the structure and dynamics of a protein called CshA which was believed to play an important role in targeting the oral bacterium Streptococcus gordonii to the tissues of the heart. The researchers were intrigued to find that CshA acts as a ‘molecular lasso’ to enable S. gordonii to bind to the surface of human cells. Such adhesive interactions are critical first steps in […]

Tooth repair could occur using Alzheimer’s drug

The renewal of living stem cells in tooth pulp could occur using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London. Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and seals the tooth pulp, but is insufficient to effectively repair large cavities. Currently dentists use human-made cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning the normal mineral level of the tooth is never completely restored. In a paper published in Scientific Reports, scientists from King’s College London have proven a way to stimulate stem cells contained in the pulp of the tooth and generate new dentine in large cavities, potentially reducing the need for fillings or cements. The novel approach could see teeth use their natural ability to repair large cavities. When fillings fail or infection occurs, dentists have to remove and fill an area that is even larger than what is affected, and after multiple treatments the […]

The lowdown on pulling teeth (the official way)

It’s an old saying, but if we get into the serious nature of pulling teeth there are some interesting views to read. As you might expect, this isn’t a two-minute procedure. There’s a whole host of information to dissect and whether you go to Limerick dentists or ones at the other side of the country, the advice stays the same. We’ll now take a look at how you should approach pulling teeth and what you need to take into account to make it as painless as possible. Who may require a tooth extraction? While most people are under the assumption that a tooth extraction should only be carried out if you have suffered some damage in your mouth, this isn’t necessarily the case. In truth, the options are endless and we could pen a dissertation mulling over each of them. To give something of an idea of how varied the reasons might be, you might require an extraction if you are receiving radiation to your head or neck area and there are teeth which have blocked the field of radiation. Alternatively, someone suffering from cancer has more chance of developing infected teeth due to the drugs that are used and […]

Putting a shine on it: Teeth whitening options broken down

It’s something that was once reserved for the rich and famous, but teeth whitening has become something that has become completely accessible to the masses. It’s something that’s offered in pretty much every dental practice in the country; whether you turn to an orthodontist Farnham has, or a practitioner in another part of the country. However, while it has become more open than ever before, it still ‘feels’ complicated to a lot of people. Realising the difference between the various at-home treatments, compared to the dentist’s chair, is something that is vital if you are looking to reap the whitest results. Following on from the above, let’s take a look at all of the teeth whitening options in detail. Professional in-office whitening Let’s start with the most extreme form of whitening; although we use the term ‘extreme’ very lightly nowadays. Sure, in-office whitening might yield the best results, but as we’ve already discussed it’s a very straightforward procedure that dentists are now used to carrying out on a daily basis. The benefit of this option in comparison to some of the others we’ll look at is the strength of the substances that your dentist will use. They are able to […]
