Root Caries and Overall Health
Recently the Partners in Prevention held its first guest speaker event which featured Dr Sally Mauriello an associate professor and coordinator of the Dental Hygiene Program at the School of Dentistry at the University of North Carolina. Dr Mauriello is one the lead researchers of the link between root caries and systemic health. She presented the finding of her research during presentations to the upper year hygiene classes at both George Brown College and the Canadian Academy of Dental Hygiene, as well as a contingent of the Partners in Prevention in Oakville. All three of these presentations were very well received by the audience and elicited many insightful questions and discussion.
Dr Mauriello’s findings have been summarized in three abstracts that have published over the past ten years a brief summary of these finding is below.
In 1996, Mauriello reported that older adults with ≥ 2 new root caries lesions were four times more likely to die during the 3 to 5 year follow period, than those with fewer than 2 root lesions.[1] A subsequent study in 1999 by the Mauriello research team extended and confirmed these findings.[2]- A 2006, Mauriello reported that amongst Americans aged 52-74 the incidence of heart attack over a 6 year period was 4.7% amongst the root caries group versus 2.4% for those without root decay.[3] In a regression analysis, root caries was significantly associated with a heart attack in this population, adjusting for periodontal pocketing, race, age, sex and the usual risk factors such as smoking, income, diabetes, hypertension and LDL
In her recent visit to Toronto, Dr. Mauriello provided some unpublished data from the Atherosclerosis Risk in the Community Study (ARIC), a large prospective study of risk factors for cardiovascular disease funded by the National Institutes of Health in the late 1980s and 1990s. ARIC tracked over 15,000 middle-aged Americans for cardiovascular disease over 10 years. Scientific articles from ARIC are still being published but the root caries connection has yet to be described. Dr. Mauriello reported that in ARIC, root caries out-weighed cholesterol as a risk factor for heart disease.
This link between root caries and overall health is still being investigated and is not completely understood at this point. However there is beginning to be more and more evidence of this link in the published literature. One of the most interesting articles has come from a Japanese research group which detected significant quantities of Streptococcus mutans in surgically removed heart valves and atheromatous plaque of patients with cardiovascular problems (Chart 1). This may indicate a pronounced or prolonged Bacteremia effect from recurrent root caries. The results of this study indicate that S. mutans is a possible causative agent of cardiovascular disease[4].

I hope that this post has given you a little more insight into the relationship between root caries and overall health and that it makes you look forward to the next Partners in Prevention guest lecture event.
Until the next time, take care

This is a very interesting and informative study. This only suggests that we should really care for our teeth and gums to prevent cavities, caries, tartar and other bacteria that are linked to diseases and other health condition.
