Gum disease is linked to an increased risk of hypertension, a new study has found. Furthermore, the more sever the gum disease, the greater a person’s risk of high blood pressure. The research by University College London's Eastman Dental Institute – the findings of which appear in the journal Cardiovascular Research – shows people with periodontitis (an advanced form of gum disease) have a higher risk of hypertension. Hypertension, according to the Centers for Disease Control and Prevention (CDC), affects 32% of all American adults, and as many as 47.2% of people aged over 30 have some form of gum disease, which is why the new research is so intriguing. While the two conditions may appear to be completely unrelated, the new research shows otherwise. And when you consider that high blood pressure is the leading cause of premature death worldwide, affecting up to 45% of adults, the findings of the study could result in much more attention being paid to combatting gum disease going forward. Specifically, the research revealed an association between moderate-to-severe periodontitis and a 22% higher risk of hypertension, Moreover, severe periodontitis was linked to a 49% higher risk of hypertension. Speaking about the findings of their research, senior author Prof. Francesco D'Aiuto, from the University College London Eastman Dental Institute in the United Kingdom, said: “Previous research suggests a connection between periodontitis and hypertension and that dental treatment might improve blood pressure, but to date, the findings are inconclusive. “Hypertension could be the driver of heart attack and stroke in patients with periodontitis,” he added.
Individuals who routinely drink more than one alcoholic beverage every day have an overabundance of bad bacteria and less good bacteria in their mouths, a new study has found. Compared to their non-drinking peers, drinkers have less good, such as Lactobacillales that help protect your gums, and more bad bacteria, such as certain Actinomyces, Bacteroidales, and Neisseria species that can lead to gum disease, heart problems and even some cancers. [Related reading: Regular excess drinking found to shorten life expectancy] Publishing their findings in the science journal Microbiome, the study authors said the acids found in alcoholic drinks could make the oral environment hostile for certain bacteria to grow, hence the lower number of so-called good bacteria. For the study, a group of more than 1,000 individuals had their saliva tested. The group included 270 non-drinkers, 614 moderate drinkers and 160 heavy drinkers. The results show that the drinkers had more Bacteroidales, Actinomyces and Neisseria species of bacteria, all potentially harmful, as well as fewer Lactobacillales, a family of bacteria associated with a reduction of gum inflammation. Talking about the findings of the study, Jiyoung Ahn, the study's senior investigator and an epidemiologist at the NYU School of Medicine, said: "heavy alcohol intake is a known risk factor for multiple chronic diseases, including cancers (head and neck, esophagus, colon and breast), liver disease and cardiovascular diseases."
A new study has uncovered further evidence that a close link exists between oral health and chronic diseases; specifically that patients with chronic kidney disease and severe gum disease have a greater risk of death than those with healthy gums. Led by the University of Birmingham in the UK, the study, the results of which were published in the Journal of Clinical Periodontology, found that oral health definitely isn’t just about teeth, again highlighting the importance of good oral hygiene. Iain Chapple, senior author of the study and a professor in periodontology, said: "The mouth is the doorway to the body, rather than a separate organ, and is the access point for bacteria to enter the bloodstream via the gums." For the research, Chapple and his colleagues analysed data from some 13,734 individuals in the US, of which 6% were found to have chronic kidney disease. The team then assessed the link between severe gum disease and mortality in people with chronic kidney disease. They found that over 10 years, the risk of death for people with chronic kidney disease was increased by 9% if they also had periodontitis (severe gum disease). Professor Chapple said that the most worrying fact is that people with periodontitis often don’t know they have it. A little bit of blood when they brush their teeth is often dismissed as normal, but if they don’t have it checked out further they could be risking problems in the rest of their bodies.
