Triclosan Slows the Progression of Periodontal Disease in Cardiovascular Patients

Posted on Thursday, June 26, 2014


Cape Town, South Africa – Today, at the 92nd General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the IADR Africa/Middle East Regional Meeting, M. P. Cullinan, The University of Queensland, Brisbane, Australia, will present a study titled “Triclosan Slows the Progression of Periodontal Disease in Cardiovascular Patients.”

The objective of this study was to determine the influence of triclosan toothpaste on the progression of periodontal disease in patients with cardiovascular disease (CVD) in a randomized controlled clinical trial. In this study, 438 patients with CVD and a minimum of 12 teeth (78% males and 22% females: mean age 61.1 +/- 8.5 years) were randomized to receive triclosan (n=223) or placebo (n=215) toothpaste. Six sites per tooth were examined annually for five years for probing pocket depth (PPD) and relative attachment level using the Florida Probe. Subgingival plaque was collected from interproximal sites, pooled and RT-PCR used to detect periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis). Data on numbers of sites showing PPD ≥4mm and loss of attachment (LOA) ≥2mm at each examination were analysed using transition modeling and Markov chain modeling of binary responses (<4/≥4 sites with PPD ≥4mm defining healthy/diseased states).

The researchers found that triclosan significantly reduced the number of proximal sites showing LOA ≥2mm between examinations by 21% on average (p<0.01). There was a smaller and only marginally significant (p=0.10) effect of triclosan in reducing the number of sites showing PPD ≥4mm, with this effect lessened for patients on anti-inflammatory medication. Triclosan also significantly increased the rate of regression from the diseased to the healthy state (p<0.05) but smoking negated this effect. There were no significant main effects of the periodontal pathogens and hypertension (p>0.10) on any of the responses.

This study shows that using triclosan toothpaste over five years slowed the progression of periodontal disease in this cardiovascular population and confirms the effect of triclosan shown in previous studies.

This is a summary of abstract #1057, “Triclosan Slows the Progression of Periodontal Disease in Cardiovascular Patients,” to be presented by M. P. Cullinan on Thursday, June 26, 2014, 8 a.m. - 9:30 a.m. in Ballroom East of the Cape Town International Convention Centre.
