article In this article by New Scientist, the team discusses how the disease may be transmitted from person to person and what the research is telling us about how it works.
The research is based on a series of experiments in which volunteers who had been diagnosed with tooth decay were given a dental implant that allowed them to take a picture of their own teeth.
The researchers then used a technique called image processing to recreate the picture and compared the images with images taken of volunteers who were not diagnosed with the disease.
The images revealed that people who had had the disease did have slightly different shapes and sizes of teeth.
In particular, people with the infection tended to have smaller teeth, but their overall shape was still very similar to that of healthy volunteers.
The study suggests that while the disease can affect different parts of the body, it is most likely to affect the jawbone, which is where most people with tooth loss tend to have their teeth extracted.
“We think it’s because of the shape of the jaw that it’s the part of the teeth that’s most susceptible to decay,” said lead researcher Dr James Kiely, from the University of Manchester, who led the study.
“If you have a small jaw you might not have as many teeth on the other side of the mouth.
So that’s where we think it goes on the surface, on the jaw itself, where the decay can occur.”
Dr Kiele explained that this could be because the bacteria that cause tooth decay are very similar in size and shape to bacteria that are responsible for plaque, which can be found in the teeth.
He said this could explain why the researchers found that people with dental implant infection were less likely to have visible tooth decay.
“The bacteria on the surfaces of the two sides of the oral cavity are the same,” Dr Kieley said.
“So the shape is probably due to this similarity of the bacteria on one side of a tooth to the bacteria in the other.”
Dr Gautam Mistry, a dentist at St George’s, University of London, said he had been surprised by the findings.
“What is most striking is that the dentists, the researchers, actually had to look at these photos and they were able to say with a high degree of confidence that this is what happened,” Dr Mistry said.
“They found that there was a very large proportion of healthy participants who had a tooth infection, but they were very small in number.
That is very unusual.”
This is a very important finding and it’s a very promising direction to go.
“The researchers will now try to get some of these healthy volunteers to have an MRI scan, which could reveal which parts of their jaw have the highest risk of decay.
Dr Kileys team is now working on a more sophisticated study to look more closely at how the bacteria can affect the brain and body, and whether it can be reversed by removing the infection.
