Water fluoridation confirmed to prevent dental decay

dfdfdThe fluoridation of drinking water was among the great public health achievements of the 20th century. A recent study ‘Water fluoridation and dental caries in US children and adolescents’, published in the Journal of Dental Research, evaluated associations between the availability of community water fluoridation and dental caries (decay) in US child and adolescent populations.
In this large study, county-level estimates of the percentage of the population with community water fluoridation from the Centers for Disease Control and Prevention were merged with dental examination data from 10 years of National Health and Nutrition Examination Surveys.
The analysis showed that children and adolescents with greater access to fluoridated drinking water were less likely to experience decay. Counties in which over 75% of the population had access to community water fluoridation saw a 30% reduction in dental decay in baby teeth, and a 12% reduction in dental decay in the permanent teeth, compared to counties in which less than 75% had access to community water fluoridation.
The findings are consistent with evidence from the last 50 years showing that water fluoridation continues to provide a substantial dental health benefit. The current study boosts the evidence by showing that the benefit is most pronounced early in life, in the baby teeth of two to eight year olds. Maria Ryan, President of the American Association for Dental Research said: "This study confirms previously reported findings and provides additional evidence in support of water fluoridation as a core public health intervention promoting oral health".

Handheld sensor immediately identifies halitosis

dfdfdHalf of adults suffer from halitosis at some point. While bad breath is just annoying in most cases, sometimes it is a symptom of serious medical and dental problems. Yet many people with halitosis may not be aware of their condition unless someone tells them. Now, a new device may be able to identify bad breath.
Researchers at the Korea Advanced Institute of Science and Technology and Massachusetts Institute of Technology (MIT) have developed a sensor that detects tiny amounts of hydrogen sulphide gas, a compound responsible for bad breath, in human breath.
To develop their sensor, the researchers used a chemical that turns brown when exposed to hydrogen sulphide. On its own, it is not sensitive to the amounts of hydrogen sulphide in human breath, but the researchers anchored it to a 3D nanofiber web, providing numerous sites for the chemical and hydrogen sulphide to react.
The researchers collected breath samples, which were mixed with 1 part per million (ppm) of hydrogen sulphide to simulate halitosis, and the mixtures were exposed to the sensors. All of the sensors turned from white to a brown, indicating successful sensing of hydrogen sulphide. The sensors could detect as little as 400 parts per billion (ppb) of hydrogen sulphide. Also, the colour-changing sensor detected traces of hydrogen sulphide added to the breath samples from ten healthy volunteers. The researchers believe the technology would be inexpensive and easy to use in medical and dental offices and could be adapted to detect other illnesses.

People with diabetes face a higher risk of mouth cancer, with women far more at risk

dfdfdNew research, published in Diabetologia, discovered that women have a 13% higher chance of developing oral cancer if they suffer from diabetes. Overall, women faced a 27% increase of developing any form of cancer if they had diabetes, while men also faced a 19% increased risk, according to the study.
With previous research showing close links between diabetes and the development of mouth cancer, the health charity the Oral Health Foundation is calling on people to be aware of the close links between their oral health and their wider well-being.
CEO of the charity Dr Nigel Carter, believes the research could help to identify individuals at risk of mouth cancer. Dr Carter said: “This could be a very significant piece of research, and one that could help to save lives. Diabetes has previously been linked to poor oral health, but this new research shows a specific link to mouth cancer.
“This makes regular dental visits an absolute must. If your dentists know that you are diabetic, they will check your mouth accordingly. For many years we have known that diabetic patients are more likely to get gum disease and need extra dental care”.
It is important for everyone to be aware of what the signs and symptoms of mouth cancer are: “Be alert to ulcers which do not heal within three weeks, red and white patches in the mouth and unusual lumps or swellings in the head and neck area. If you experience any of these visit your dentist immediately”.
