BIRMINGHAM, England—Supplementing diet with a special combination of fruit and vegetable juice powder concentrates may help to combat chronic gum disease when combined with conventional dental therapy, according to scientists at the University of Birmingham.
The results of a preliminary, randomized, controlled study—published in the Journal of Clinical Periodontology (Oct. 18, 20110)—show taking a daily dose of capsules containing concentrated phytonutrients improved clinical outcomes for patients with chronic periodontitis (deep-seated gum disease) in the two months following non-surgical periodontal therapy, with additional beneficial changes recorded at five and eight months after therapy.
Volunteers aged 30 or older suffering from chronic periodontitis were randomly assigned to one of three groups taking a) fruit and vegetable powder concentrate capsules; b) fruit, vegetable and berry powder concentrate capsules or c) placebo. The supplements (Juice Plus+®) were taken daily following non-surgical scaling and cleaning of the root surfaces of the teeth.
Sixty volunteers completed the two-month review and 54 completed the eight-month review. Clinical outcomes improved significantly in all groups at two months as expected from the standard mechanical therapy. However, in the fruit and vegetable group, and in the fruit, vegetable and berry group, there were additional statistically significant improvements in gum pocketing (a measure dentists use to gauge gum health) at two months. Improvements in gum bleeding followed at five months and in lower dental plaque levels at eight months.
The research team concluded: “Adjunctive juice powder concentrates appear to improve initial pocket depth reductions in nutritionally replete patients where plasma micronutrient bioavailability is attainable."
Study leader, Professor Iain Chapple of the Periodontal Research Group at the University Of Birmingham School Of Dentistry, added: “This was a very complex study and we were surprised to see these outcomes, because when the standard therapy works so well, it creates a ‘ceiling effect’ whereby it is difficult to improve further. It’s difficult to assess the size of the additional clinical benefit, because these patients were well nourished, and had the highest quality standard therapy anyhow. We are very interested in what the effects will be in people who are nutritionally depleted, and in those who do not or cannot access high quality gum care."
The Birmingham researchers are now leading a large multicentre trial in partnership with researchers in Holland and Germany to test the clinical significance of these findings in such an “untreated" population.
