“…The gel used in this study contains potassium hydroxide, which is a strong alkaline component that may be able to neutralize acids in aqueous environments. 22 Another component present in the formulation of the bleaching gel is sodium fluoride, which is broadly added to toothpastes as a caries preventive element. According to the manufacturer, these components play an important role in desensitizing mechanisms, preventing demineralization development and loss of hardness.…”

Aim: This study aimed to evaluate the effect of a laser-activated bleaching agent containing titanium dioxide (TiO 2 ) nanoparticles on enamel roughness and hardness. Materials and Methods: Twenty human premolars were randomized into two groups according to the bleaching treatments performed: HP – 35% hydrogen peroxide and HP + TiO 2 – 30% hydrogen peroxide containing TiO 2 light-activated by diode laser (980 nm). It was performed two bleaching sessions with an interval of 7 days. Microhardness and roughness of the enamel were assessed at three times: T0 – Before 1 st appointment, T1 – after 2 nd appointment, and T2–7 days after 2 nd appointment. Results: The HP + TiO 2 did not cause changes on enamel roughness and hardness and presented the same effects of the HP. Conclusions: Both bleaching agents showed no difference between them. Then, it is possible to conclude that both are viable for clinical use during in-office dental bleaching technique regarding the microstructural changes that they might cause.

“…[9][10][11] The association of hydrogen peroxide with calcium has been reported to reduce enamel mineral alterations when bleaching and erosion are combined. [12][13][14][15][16] During the bleaching treatment, the patients should maintain their oral hygiene, in which dentifrices play an important role. Their use, together with a toothbrush, may increase or decrease enamel and dentin wear.…”

The aim of this study was to evaluate the effect of erosive/abrasive cycles and two different levels of abrasiveness of dentifrices over enamel and dentin subjected to bleaching. Methods: Enamel and dentin bovine specimens were prepared and submitted to an at-home bleaching treatment using 9.5% hydrogen peroxide gel, which was applied daily (30 min/14 days). Concomitant with bleaching, an erosive cycle was performed using citric acid (0.3%, pH 3.8, 5 mins, 3×/day), followed by immersions in artificial saliva for remineralization (30 mins). Abrasion was done with two (high and low abrasiveness) dentifrices (2×/day, 120 seconds) after the first and third erosive immersion each day. Enamel and dentin softening were assessed by microhardness and erosive tooth wear by optical profilometry. Data were submitted to repeated measures ANOVA, followed by the Tukey's test with a significance level of 5%. Results: For the enamel and considering the erosive-abrasive cycle, significant differences were found between the groups tested, the bleaching, and the abrasiveness of the dentifrice tested; however, the final microhardness values were significantly lower than the initial ones. For dentin, differences were found between the eroded/abrasion and the non-eroded/abrasion groups, with the former presenting lower microhardness values compared with the latter. In addition, bleaching decreased the microhardness values only for the highly abrasive dentifrice, and the final values were lower than for the initial ones for all tested groups. Conclusion: The use of high and low abrasiveness dentifrices during bleaching and concomitant with erosion/abrasion cycles is more harmful to dentin than to enamel. Clinical Relevance: Although bleaching is considered a conservative treatment, it can cause deleterious effects to dental hard tissue. The association of an at-home bleaching technique with erosion and high-or low-abrasive dentifrices harms dentin more than enamel.
