Clinical Trial Summary

The objective of this study is to determine the metagenomic and metatranscriptomic analysis of clinical samples.


Description:

This study is a blinded, non-randomized, crossover design. Subjects who meet the inclusion/exclusion criteria will be enrolled in the study. Following enrollment, subjects will be asked to use a washout dentifrice (#200000035883/001/000) for a minimum of 1 week. Fasting plaque will be collected at Baseline and then again at a duplicate baseline collection up to 1 week after the baseline collection. Subjects will be assigned a new dentifrice (#200000035883/001/000) to use for 12 weeks. After 12 weeks' use, fasting plaque will be collected. There will be a duplicate plaque collection up to 1 week after 12 week collection. Subjects will be given a new dentifrice (#200000040228/001/000) to use for the next 24 weeks. After 24 weeks' use, fasting plaque will be collected, and there will be a duplicate plaque collection up to 1 week after this collection.
