Gum Disease Bacteria may Facilitate Rheumatoid Arthritis

As stated over on the risks of keeping wisdom teeth page, gum disease (periodontal disease) has been shown to have associations with many different systemic diseases. One such systemic disease is rheumatoid arthritis (RA). So far, any mechanism has remained elusive. In a recent study appearing in PLoS Pathogens, researchers at the University of Louisville School of Dentistry Oral Health and Systemic Diseases and other researchers from the European Union’s Gums and Joints project have uncovered how the bacteria responsible for periodontal disease known as Porphyromonas gingivalis effects rheumatoid arthritis. The researchers showed that this bacteria leads to faster progression, greater severity and earlier onset of RA and can cause bone and cartilage destruction. The researchers found the bacteria produces a unique enzyme, peptidylarginine deiminanse (PAD), which enhances collagen-induced arthritis (CIA), which is an arthritis produced in the lab designed to mimic RA. PAD changes residues of some proteins into citrulline that the body recognizes as intruders which leads to an immune attack. In RA patients, this leads to chronic inflammation which causes  bone and cartilage destruction in joints. Another oral bacteria known as Prevotella intermedia was also studied by did not produce this response to PAD as Porphyromonas gingivalis […]

Using Teeth to Determine Where you are From

An interesting article titled “The Pb isotopic record of historical to modern human lead exposure,” appears in the journal Science of The Total Environment written by George D. Kamenov and Brian L. Gulson (vol. 490, pp. 861-870, 2014). George Kamenov is a University of Florida geology professor. The article describes how trace amounts of lead present in teeth can give clues about what geographical region the teeth (and the person) came from. What is interesting about this article, is that the lead in the teeth can be used to pinpoint the geographic area where the teeth originated from. This is because lead is composed of four different isotopes which fluctuate in different rocks and soils around the world. As children grow they inhale dust and ingest soil which contains the different isotopes of lead. As tooth enamel forms during childhood, it locks in the lead signals from the environment. The first molar has its enamel formed by around age 3, incisor and canine enamel is formed by around age 5, and third molar (wisdom teeth) enamel is formed by around age 8. If a child moves geographic regions during this time, the different teeth can persevere the lead in the environment […]

Treating Gum Disease in Australians Leads to Better Vascular Health

According to a new study in the journal of Hypertension, a single session of gum treatment in Aboriginal Australians can lead to a significant decline in the thickening of the wall of the carotid artery a year later. The thickness of the wall of the arteries is a risk factor for heart disease. Aboriginal Australians are generally thought to have poorer oral health and higher rates of cardiovascular disease when compared to other Australian groups. The researchers say that the effect is comparable to a 30% fall in low density lipoprotein cholesterol which is known as bad cholesterol and associated with a decreased risk of heart disease. The researchers also note that such an effect is equivalent to reversing four years of aging or 25 mm Hg lower systolic blood pressure. Periodontal or gum disease is an inflammatory disease which affects the soft and hard structures supporting the teeth and leading them to become swollen and red. In more advanced forms of periodontal disease the gum tissue can be destroyed and the gums pull away from the teeth. Even more troubling is that bone can be lost and teeth may fall out. Cardiovascular disease also known as atherosclerosis is the most […]
