Oral bacteria may cause heart disease / Bakteri dalam mulut dapat menyebabkan penyakit jantung

 

If you’re worried about heart disease, you can easily spend thousands of dollars each year trying to prevent it, paying hand over fist for prescription medicines, shelves of healthy cookbooks, fitness machines for your home, and a gym membership. A number of recent studies suggest that you may already have a cheap and powerful weapon against heart disease, strokes, and other heart disease conditions. It is none other than the toothbrush.

A report from the University of Florida shows that introduction of oral bacteria into the bloodstream in mice increased risk factors for atherosclerotic heart disease. Atherosclerosis, also called “hardening of the arteries,” develops when deposits of fats and other substances in your blood begin to stick to the sides of your arteries. These deposits, called plaques, can build up and narrow your arteries, clogging them like a plugged-up drain. If these plaques ever block the blood flow completely, you could have a heart attack or stroke, depending on the location of the blockage. In the study, the researchers infected mice with four specific bacteria (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum) that cause gum disease and tracked their spread. Once the bacteria were detected in the mouse gums, heart and aorta, researchers saw an increase in risk factors, including cholesterol and inflammation, associated with heart disease. 

Apakah anda takut terkena penyakit jantung dan menghabiskan banyak uang untuk membeli obat-obatan, makanan sehat, dan alat-alat olahraga? Penelitian terbaru dalam kedokteran gigi mengemukakan bahwa dengan menyikat gigi dua kali sehari dapat mencegah penyakit jantung dan stroke.

Penelitian yang dilakukan di Universitas Florida menunjukkan bahwa bakteri dalam mulut yang disuntikkan ke pembuluh darah tikus meningkatkan resiko atherosclerosis. Atherosclerosis merupakan keadaa mengerasnya pembuluh darah jantung yang disebabkan karena plak-plak dalam pembuluh darah. Plak ini akan penyempitan pembuluh darah dan penyumbatan aliran darah ke jantung yang berakhir pada stroke. Pada penelitian ini, peneliti menyuntikkan empat macam bakteri yang biasa ada dalam mulut seperti Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum. Setelah bakteri terdeteksi dalam pembuluh darah tikus terjadi peningkatan pada level kolesterol dan inflamasi yang berhubungan dengan penyakit jantung.
