Abstract
OBJECTIVES: To assess the whitening efficiency and patient satisfaction after usage of commercially available toothpastes with the different whitening ingredients. MATERIALS AND METHODS: This randomized controlled trial study comprised 161 participants who were randomly divided into eight groups based on used whitening or control/conventional toothpaste (Colgate Max Expert White [CMEW], n = 20; Signal Daily White [SDW], n = 20; Himalaya Sparkly White Herbalis [HSWH], n = 20; Signal White System [SWS], n = 20; Rembrandt Deeply White + Peroxide [RDWP], n = 20; Splat Extreme White [SEW], n = 20; Splat White Plus [SWP], n = 21; and Kalodont Multi Repair [control], n = 20). Tooth color and color change were evaluated using a spectrophotometer (CIELAB coordinates, ΔEab*, ΔE00, whiteness index change [ΔWID]). Measurements were performed at baseline, 30 days and 60 days after the beginning of treatment, and 30 days after completing treatment - follow-up. Side effects and satisfaction with the whitening outcome were reported throughout the questionnaire. RESULTS: The results for ΔL*, Δa*, and Δb* showed an increase in lightness and decrease in yellowness for all tested whitening toothpastes compared to the control group after 30 days of use (p ≤ 0.05). Also, significant tooth color difference (ΔEab*, ΔE00) and whiteness index change (ΔWID) were recorded for all tested whitening toothpastes 30 days and 60 days from the beginning of use (p ≤ 0.05). Toothpaste containing a combination of urea peroxide and enzyme ingredients (SEW) demonstrated the highest and the longest whitening effect. CONCLUSIONS: Whitening toothpastes can show perceptibly whitening effect after a short time of usage, but without a long-lasting impact. CLINICAL RELEVANCE: Toothpaste containing a combination of enzymes and peroxides showed the best whitening performance compared to those containing only enzymes, peroxides, or abrasives. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04460755.
