According to recent research published in the Journal of Dentistry, researchers have found that bleaching toothpaste with higher HP yields a better shade change than other toothpaste after 12 weeks.
The efficacy of whitening toothpaste is questionable and controversial. Clinicians, patients, and researchers have expressed concern with whitening toothpaste due to the risk of wearing the dental structure and the potential for disappointment if the advertised cosmetic results are not achieved.
However, this randomized double-blinded clinical trial was carried out to evaluate the bleaching efficacy and incidence of contact hypersensitivity of three kinds of bleaching toothpaste.
Hyun-Jung Kim and associates from the Department of Conservative Dentistry, Kyung Hee University Dental Hospital, Seoul, Republic of Korea carried out the present study with a total of forty-nine participants having above A2 shade on the maxillary central incisor (#11) and canine (#13). All the participants were randomized into three groups: TW group (n = 15), 0.75 % HP-containing toothpaste (Toothwhole white); VL group, 0.75 % HP-containing toothpaste (Vussen 7); and VH group , 2.8 % of HP-containing toothpaste (Vussen 28).
Participants were instructed to manually brush their teeth for 3 min, 3 times per day for 12 weeks. They were followed-up after 4 and 12 weeks. Shade measurements were performed using a spectrophotometer (SP), and data were calculated. Additionally, visual inspection (VI) using the Vitapan classical shade guide was also performed, and the correlation between the two measurements was analyzed. The incidence of contact hypersensitivity at each follow-up was recorded.
The key findings observed by the authors were-
a. At the 12- week follow-up, all groups showed above 3.46, and above 2.25 for tooth #11.
b. For tooth #13, the values of VH and TW groups only were above those thresholds.
c. Shade change varied according to toothpaste and follow-up points.
d. SP and VI showed a moderate positive correlation.
e. Contact hypersensitivity was not significantly different among the groups.
Hence, the authors concluded that "bleaching toothpaste with higher HP yields a better shade change than other toothpaste after 12 weeks."
The use of bleaching toothpaste with a higher HP concentration results in a better shade improvement, they further added.
