Zinc-doped polymeric nanoparticles in the treatment of dentin hypersensitivity: A randomized, double-blind, placebo-controlled clinical trial.

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 young adults, adults and middle-aged adults, both men and women.

Sixty patients with DH were enrolled in the study.

Patients were recalled 7 times throughout 21 days for sensitivity screening.

How the Study Was Run

The design is described as randomized, double-blind, placebo-controlled and parallel-group.

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

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

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

The Vitamin D, K2, Magnesium and Zinc group and the comparison group ran side by side rather than switching.

This study was a parallel, double-blind, placebo-controlled, single-center randomized clinical trial.

Zinc-doped polymeric nanoparticles (NPs) (test group n = 30) and placebo solution (control group n = 30) were applied.

Visual analogue scale (VAS) by both air blast and percussion tests, and the Schiff air index were used to follow up the symptoms of DH.

What Was Measured

PubMed files the paper under topics including Dentin Sensitivity, Nanoparticles, Zinc, Pain Measurement, Dentin Desensitizing Agents and Polymers.

The authors tagged it with the keywords Hypersensitivity.
