PENHA, Elizandra Silva da et al. Evaluation of different in-office tooth whitening systems. RFO UPF [online]. 2015, vol.20, n.3, pp. 281-286. ISSN 1413-4012.

Objective: To evaluate two in-office tooth whitening products and verify their effectiveness and post-treatment tooth sensitivity. Methods: 12 volunteers were selected and each of their upper arches underwent an imaginary division from the midline, forming two groups: the LD group comprises the upper right hemiarch (tooth 11-15), and the LE group comprises the upper left hemiarch (tooth 21-25). The lower arch formed the control group. The LD group received 35% hydrogen peroxide Whiteness HP™ (FGM Dental Products, Joinville, SC, Brazil) and the LE group received 35% hydrogen peroxide Pola Office™ (SDI Limited, Bayswater, VIC, Australia) in three consecutive sessions with a one-week interval. Color was evaluated with the visual scale Vitapan Classical (Vita Zahnfabrick, Bad Sackingen, BW, Germany) at the beginning of each session and 12 days after the last session of the whitening treatment. At the end of each session, the volunteers recorded the occurrence of tooth sensitivity in Wong-Baker pain faces rating scale. Results: The whitening agents used had the same whitening potential and there was no statistically significant difference (P<0.05) regarding the intensity of sensitivity when comparing both products. Conclusion: There was no difference between the products regarding whitening potential and tooth sensitivity.
