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 […]

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 […]

A Study of Outcomes Related to Wisdom Teeth Removal

An interesting article titled “A Prospective Study of Clinical Outcomes Related to Third Molar Removal or Retention,” appears in the American Journal of Public Health (April 2014, Vol 104, No. 4) written by Greg J. Huang and et al. The article is a companion article to another also on wisdom teeth in the April 2014 issue of the journal. I discussed the companion article last week in the blog post http://blog.teethremoval.com/practice-based-wisdom-teeth-removal-study/. The article opens by mentioning the controversy surrounding the removal of wisdom teeth. On one side some have advocated for wisdom teeth to be removed to prevent future pathology and minimize risks, others have advocated for wisdom teeth to be removed to prevent lower incisor crowding, and others have argued for wisdom teeth to be removed to prevent periodontal pathology. On the other side some have advocated for wisdom teeth to be retained to avoid complications that can result, with some being lasting and permanent. This study set out to better explore long term outcomes of retaining or removing wisdom teeth by following up with patients over a period of two years. The methods used for the subjects in the study were the same as in the previous companion […]

Periodontal Disease and Pregnancy Risks

An often disagreed point in the literature is whether or not periodontal disease is associated with adverse pregnancy outcomes such as preterm births and low birth weight. I have discussed this some more on the risks of keeping wisdom teeth page over at http://www.teethremoval.com/risks_of_keeping_wisdom_teeth.html. I discussed how in a meta-analysis of 10 randomized trials in January 2011 found no evidence in favor of periodontal disease being associated with preterm births and low birth weight. The source for this study is Mariana Fampa Fogacci and et al. The Effect of Periodontal Therapy on Preterm Low Birth Weight: A Meta-Analysis. Obstetrics & Gynecology. vol. 117. issue 1. pages 153-165. January 2011. In a letter in J Can Dent Assoc 2012; 78: c120 there is an articled titled “Periodontal Disease and Pregnancy Risks,” which was published on on September 24, 2012 over at http://www.jcda.ca/article/c120 discussing periodontal disease and potential pregnancy risks. A reader from Tennessee writes in questioning why the authors undertook a study that was by Fahey M. titled “Periodontal health isn’t yet the answer to preterm birth”. J Can Dent Assoc. 2012;78:c31. The reader is wondering why the study looking at whether or not periodontal disease has an effect on pregnancy risks […]

Removing Wisdom Teeth May Improve The Periodontal Health of Remaining Teeth

An interesting article titled “Removal of Symptomatic Third Molars May Improve Periodontal Status of Remaining Dentition,” by Carolyn Dicus-Brookes and et al. appears in the Journal of Oral and Maxillofacial Surgery (vol. 71, pp. 1639-1646, 2013). The article seeks to explore the impact of removing wisdom teeth on the periodontal status of adjacent second molars and other teeth located in the mouth specifically for patients who have mild symptoms of pericoronitis. As discussed recently over at Upcoming Changes to JOMS and AAOMS in 2014, select articles in JOMS will have press releases written by AAOMS staff to accompany them. This is one of those articles so that feature appears to have already been rolled out. To get an idea of what the press release entails I will briefly describe it. It is very short (less than 10 sentences) and fits on 1 page. It was released on October 1, 2013. The press release states 69 patients were followed with mild symptoms of pericoronitis. All patients had wisdom teeth prior to the study start and had an average age of 21. The main conclusion of the study as stated in the press release, is that at the beginning of the study […]
