Effect of Three Different Zinc Lactate-Added Tablets on Volatile Sulfur Compounds - A Comparative Study.

What Was Tested

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

The OralChroma2 © device was utilised to evaluate VSC in the oral air.

Why It Was Studied

It was planned in four parallel groups, a single-centre, single-blinded randomised-controlled trial.

Who Took Part

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

Eligible participants had to score VSC ≥75 parts per billion (ppb) at the basal measurement to enter.

How the Study Was Run

The researchers set it up as a randomized, single-blind, placebo-controlled and parallel-group study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Only one side, usually the participants, was kept unaware of whether Vitamin D, K2, Magnesium and Zinc was given.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

Groups ran in parallel: each of the participants stayed in one arm throughout.

VSC were scored at baseline, after sucking one tablet, after 30 minutes, 1 hour and 2 hours.

Data were analysed with SPSS (version 22).

Comparisons within the groups were performed using a paired T-test, and among the groups with an unpaired T-test.

What Was Measured

PubMed files the paper under topics including Tablets, Halitosis, Sulfur Compounds, Zinc Compounds and Lactates.
