Et si en matière d’AVC, les parodontopathies étaient plus inductrices que le diabète !

 

Les accidents cardio-vasculaires (AVC) sont la proie des statisticiens qui voudraient bien cerner les pathologies ayant la particularité d’en accroître la prévalence.

La structure des parois des vaisseaux, notamment leur rigidité, leur fragilité et leur texture, perturbée par un métabolisme déviant constitue le principal soubassement du risque ; et on sait que le diabète altère profondément ces paramètres et constitue ainsi un facteur de risque d’AVC.


Mais la nidation bactérienne qui imprègne les parois des vaisseaux s’avère également être une composante du risque vasculaire.


A cet égard, il a été établi que la parodontopathie pourrait représenter un risque d’AVC non fatal deux fois supérieur au risque imputable au diabète !

 

Lors d’une conférence tenue au 89° Congrès de l’International Association for Dental Research (IADR au mois de mars 2011), il a même été affirmé que la maladie parodontale serait plus agissante que l’hypertension sur le risque d’AVC non fatal !

 

 

Gum disease bigger risk than diabetes

4th Apr 2011

New research suggests that gum disease carries a higher risk of causing a stroke than diabetes, and its impact is nearly the equivalent of high blood pressure as a major cause of strokes.

High blood pressure (hypertension) and diabetes (diabetes mellitus) are widely recognised as major risks contributing to non-fatal strokes (ischemic strokes).

In recent years, there has been growing evidence of the link between gum disease (periodontitis) and strokes.

New research indicates people are twice as likely to suffer a non-fatal stroke as a result of gum disease compared to diabetes.

The data also suggests its impact is equivalent to people with high blood pressure.

The research, presented at the 89th International Association for Dental Research (IADR) General Session and Exhibition in San Diego last month, is another reminder of the serious impact that poor oral health poses to general health and wellbeing.

Dr Nigel Carter, chief executive of the British Dental Health Foundation, said: ‘Obesity, alcohol abuse, poor diet and smoking are generally well-known risk factors that can cause strokes. Less well-known are the risks caused by gum disease.

‘This research is significant because it helps to quantify the importance of oral health compared to other risk factors. The findings are startling. The fact that high blood pressure carries a similar risk to gum disease is in itself a significant finding. The other finding that shows that gum disease nearly doubles the risk of non-fatal strokes, compared to diabetes, is totally unexpected.

‘The research sends a clear message that the risks caused by poor oral health should not be overlooked or considered less important when compared to others factors.'
