A Clinical Investigation of the Efficacy of a Dual Zinc plus Arginine Dentifrice for Controlling Oral Malodor.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Who Took Part

By PubMed's age tags, the people studied were adults, both men and women.

A total of eighty (80) adult male and female subjects from Chengdu, People's Republic of China, were enrolled in this clinical study.

Following an assessment of the oral soft and hard tissues, subjects were evaluated for baseline oral malodor by a panel of four trained and calibrated judges using a nine-point organoleptic hedonic scale.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

The participants were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

Neither the participants nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

They were then randomly assigned to one of two treatment groups (Dual Zinc plus Arginine - test; regular fluoride dentifrice - control).

What Was Measured

The subject headings attached to it are Analysis of Variance, Arginine, Dentifrices, Fluorides, Halitosis, Silicic Acid and Sodium Fluoride.

The authors tagged it with the keywords clinical study, oral malodor, organoleptic method, zinc, zinc citrate and zinc oxide.
