Effects of Toothpaste Containing 2% Zinc Citrate on Gingival Health and Three Related Bacteria-A Randomized Double-Blind Study.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Gingivitis is the initial stage of periodontitis, one of the most common oral diseases and the primary cause of tooth loss.

Why It Was Studied

Chinese Clinical Trial Registry (Clinical trial registration no.: ChiCTR1900020592) (09/01/2019).

Who Took Part

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

Eleven volunteers with the same oral health status were randomly assigned to the treatment (n = 5) and control (n = 6) groups.

Dental plaque from four areas of the mouth (FDI criteria) was collected at the same timepoints.

How the Study Was Run

In design terms this was 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.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

The plaque index, gingival index, and bleeding index were measured at baseline (0 day), 3 weeks, and 3 months.

A total of 132 dental plaque samples were analyzed using quantitative PCR (qPCR) to monitor the abundance of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia.

What Was Measured

The subject headings attached to it are Toothpastes, Gingivitis, Dental Plaque, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Porphyromonas gingivalis and Periodontal Index.

The authors tagged it with the keywords antibacterial, gingival health and zinc citrate.
