The systemic effect of a food additive on dental plaque and calculus

  title={The systemic effect of a food additive on dental plaque and calculus},
  author={S. Wikner and Christina Timander and J. Bergstr{\"o}m},
A food additive containing the brown algae Ascophyllum nodosum SW1313 was used in an eight-week clinical trial with the purpose to explore its possible effect on reducing supragingival plaque and calculus. 105 subjects were randomly assigned to one of three groups, each containing 35 subjects at baseline. Two groups received tablets of either a low (125 mg) or a higher (250 mg) concentration of the algae. A third group (control) received placebo tablets. Significant reductions in plaque levels… Expand

Figures and Tables from this paper


Reduction of dental plaque deposition in humans by oolong tea extract.
OTE was found to significantly inhibit plaque deposition in volunteers, although mouthrinsing with OTE solution had no significant effect on the number of mutans streptococci in unstimulated whole saliva. Expand
Dental calculus composition following use of essential-oil/ZnCl2 mouthrinse.
Group C regimen with essential oil/ZnCl2 mouthrinse and standard dentifrice showed a significant anti-microbial effect and favored the formation of DCPD, the most soluble Ca-P in HDC. Expand
The inhibitory effect of funoran and eucalyptus extract-containing chewing gum on plaque formation.
The results suggest that FG and EG may be useful in inhibiting dental plaque formation. Expand
Use of the feed additive sodium hexametaphosphate to prevent dental calculus in squirrel monkeys (Saimiri spp.).
It is concluded that HMP is ineffective in squirrel monkeys with preexisting dental calculus, because dental calculus did not differ significantly between the experimental groups. Expand
Effects of oral rinsing with triclosan and sodium lauryl sulfate on dental plaque formation: a pilot study.
Mouthwashes containing 0.3% or 0.15% triclosan in combination with 1.5% sodium lauryl sulfate (SLS) produced a significant reduction in plaque formation in a test panel of 11 students who refrainedExpand
Inhibitory effects of cacao bean husk extract on plaque formation in vitro and in vivo.
Results indicate that CBH possesses significant antiplaque activity in vitro and in vivo. Expand
Supragingival irrigation with 0.06% chlorhexidine in naturally occurring gingivitis. I. 6 month clinical observations.
The purpose of this study was to assess the efficacy of supragingival irrigation with 0.06% chlorhexidine gluconate (CHX) on naturally occurring gingivitis. The relative benefit of CHX irrigation inExpand
Plaque formation and gingivitis after supervised mouthrinsing with 0.2% delmopinol hydrochloride, 0.2% chlorhexidine digluconate and placebo for 6 months.
The results from this clinical trial indicate that supervised rinsing with 0.2% delmopinol hydrochloride or with 1% chlorhexidine digluconate twice daily for 60 s as a supplement to normal mechanical oral hygiene procedures resulted in less plaque formation and gingivitis than rinsed with placebo.

The use of PVP-iodine as an adjunct to non-surgical treatment of chronic periodontitis.
It was demonstrated that non-surgical periodontal therapy resulted in improved gingival conditions, reduced PPD, and gain in PAL and the topical application of 0.1% PVP-iodine in conjunction with the mechanical root debridement established conditions which further improved the outcome of therapy.

Anticalculus effects of a novel, dual-phase polypyrophosphate dentifrice: chemical basis, mechanism, and clinical response.
The structure of polypyroph phosphate as compared to the parent pyrophosphate molecule, the rationale for its improved chemistry, and, in particular, its tartar control chemistry are described. Expand
