Survival of multiple-surface ART restorations using a zinc-reinforced glass-ionomer restorative after 2 years: A randomized triple-blind clinical trial.

What Was Tested

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

Who Took Part

According to the abstract, 218 participants were involved.

The age groups tagged for this paper are teenagers.

A total of 218 participants, average age 15.4 years (SD=0.2), with an occluso-proximal carious lesion in a permanent (pre-) molar were included.

How the Study Was Run

In design terms this was a randomized and parallel-group study.

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

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

A randomized triple-blind parallel group clinical trial was used.

Restorations using test (ChemFil Rock) and control (Fuji IX GP) restoratives were placed according to the ART method by four calibrated operators.

Restoration survival curves were estimated using the Kaplan-Meier method and difference between dependent and independent variables tested with a Wald (chi-square) test.
