The long-term effect of a zinc acetate and chlorhexidine diacetate containing mouth rinse on intra-oral halitosis-A randomized clinical trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

To evaluate the long-term effects of a zinc acetate and chlorhexidine diacetate mouth rinse (Zn/CHX) on intra-oral halitosis.

Who Took Part

PubMed indexes the participants as adults, middle-aged adults and older adults, both men and women.

Forty-six adults with intra-oral halitosis were randomized into a 6-month, double-blind, placebo-controlled clinical study.

The presence of intra-oral halitosis was evaluated at baseline, 3 and 6 months after treatment by assessment of organoleptic score (OLS) and by total volatile sulphur compounds (T-VSC), hydrogen sulphide (H2 S) and methyl mercaptan (MM) concentrations in exhaled air.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

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.

Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

The subject headings attached to it are Anti-Infective Agents, Local, Chlorhexidine, Halitosis, Mouthwashes, Sulfur Compounds and Zinc Acetate.

The authors tagged it with the keywords Zn/CHX rinse, bad breath, hydrogen sulphide, mouth rinse and volatile sulphur compounds.
