Abstract
This study aimed to compare the efficacy of tooth whitening and prevalence of tooth sensitivity between 6% hydrogen peroxide (HP) and 10 % carbamide peroxide (CP) at-home whitening systems. Forty-eight patients were chosen and divided into two groups: 6% HP (Tion Take Home With, WI) and 10% CP (Tion Take Home Platinum, PL). Both groups followed the manufacturer's instructions. The whitening procedures were performed over a 10 day period of 1 h per day in WI and a 14 day period of 2 h per day in PL. Tooth color changes were measured with a spectrophotometer. The pain intensity was assessed using a numerical rating scale. No significant differences in ΔE*ab, ΔE00, and ΔWID were found between the groups. Tooth sensitivity was more prevalent in WI than in PL. Ten days of 6% HP use was as effective as 14 days of 10% CP.
期刊介绍：
Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
