Effectiveness of Different Candies Against Bad Breath (HALIDROP)

This study is to analyze whether the candies can relieve or eliminate bad breath, both subjectively and objectively.

This study is to systematically examine an existing candy, which is easily available and is intended to relieve or eliminate bad breath. The main aim of the study is to determine the effectiveness of the candies on the subjective perception of bad breath. The secondary outcome of the study is to investigate whether there is actually a decrease in volatile sulphur compounds (VSC) in the exhaled air and also a decrease in bad breath during organoleptic measurement. The purpose of the study is to investigate whether the different candies can relieve or eliminate bad breath, both subjectively and objectively.

Three different variants of a candy are being tested by each participant. The candies are randomly assigned to the subjects, so that each subject has tested each of the three candies once. Randomization creates a different order for each participant. The study will be carried out on three different days.

Intake of 3 different candies against bad breath on three different days (2-days interval each) after artificially creating a temporary bad breath (by eating of chips and cheese); analysis of breathing during intake of candy both subjectively and objectively
