Tooth whitening efficacy of self-directed whitening agents vs. 10% carbamide peroxide: A randomized clinical study
This randomized, controlled, single-blind, four parallel group clinical study evaluated the potential for tooth colour whitening by self-directed whitening agents - two whitening dentifrices and a peroxide barrier-free varnish - in comparison to a 10% carbamide peroxide agent (CP) as positive control for a period up to 90 days, in young adults.
