Abstract
Objectives: The aim of this study was to compare the tooth bleaching effect of two whitening materialsin toothpaste i.e., hydroxyapatite and hydrogen peroxide on. In a randomized, double blinded controlledclinical trial, 85 participants with tooth colorations were assigned to use one of three toothpastes containingeither hydroxyapatite (0.25%), hydrogen peroxide (0.75%), or no active ingredient (placebo). Thepatients were examined at baseline and 1, 2, and 3 months after usage.
Methods: The patients underwent an oral examination, tooth shade measurement, and a subjectiveevaluation. During the oral examination, the patient’s oral health status was determined. ShadeEye NCCand Vita classical shade guide were used to determine the tooth color. Further, the patients were askedto assess the color of their own teeth using a visual analog scale (VAS) scale (range, 1-5).
Results: According to the CIELAB system, a significantly greater color change (Δb*) was observed inthe hydrogen peroxide group (2.10±1.54) than in the hydroxyapatite (1.50±1.09) and control (0.94±0.75) groups after 3 months of toothpaste usage (P<0.002). The ΔE*color change was not statisticallysignificant among the 3 groups at each time point (P>0.05). The subjective evaluation results of thehydroxyapatite (P=0.023) and hydrogen peroxide (P=0.047) groups were statistically significant at eachtime point.
Conclusions: The hydrogen peroxide-containing toothpaste caused significant lightening of tooth colorationthan the hydroxyapatite and placebo toothpastes.
