“…Damage to soft tissues from tooth whitening can be minimized under the supervision of a dentist with a rubber dam. 154 However, preventing the exposure of soft tissues to whitening agents is difficult at home. Several studies have reported the side effects of whitening agents on soft tissues.…”

Whitening agents, such as hydrogen peroxide and carbamide peroxide, are currently used in clinical applications for dental esthetic and dental care. However, the free radicals generated by whitening agents cause pathological damage; therefore, their safety issues remain controversial. Furthermore, whitening agents are known to be unstable and short-lived. Since 2001, nanoparticles (NPs) have been researched for use in tooth whitening. Importantly, nanoparticles not only function as abrasives but also release reactive oxygen species and help remineralization. This review outlines the historical development of several NPs based on their whitening effects and side effects. NPs can be categorized into metals or metal oxides, ceramic particles, graphene oxide, and piezoelectric particles. Moreover, the status quo and future prospects are discussed, and recent progress in the development of NPs and their applications in various fields requiring tooth whitening is examined. This review promotes the research and development of next-generation NPs for use in tooth whitening.

“…Different tooth bleaching techniques on vital teeth performed or supervised by the dentist are described in the literature in search of color change 5–8 . Among them, the most established is the in‐office bleaching which uses higher concentrations of hydrogen peroxide (HP) (up to 40%), 9–13 the gel application being performed by the dentist, 14 and the at‐home bleaching, which uses lower concentrations of HP (up to 10%), performed by the patient himself with the application of bleaching gel in custom trays 15 . However, both techniques showed adverse effects and tooth sensitivity induced by bleaching was among the most prevalent 16 …”

ObjectiveTo evaluate the penetration of hydrogen peroxide (HP) into the pulp chamber and the color change of different bleaching varnishes in low concentrations used for at‐home bleaching.Materials and MethodsNinety healthy premolars were used, randomly distributed into nine groups (n = 10) according to bleaching varnish (PL, PolaLuminate; VS, VivaStyle Paint On Plus; CA, Cavex Bite&White whitening pen and; AW AlignerWhite) and time (10 and 30 min), and a control group (no bleaching). The penetration of HP was evaluated by UV–Vis spectroscopy. To evaluate the color change (ΔEab, ΔE00, ΔWID) a digital spectrophotometer was used (α = 0.05).ResultsThe AW group in 10 min and the control group showed similar and lower HP penetration in the pulp chamber when compared to the other groups (p = 0.003). Increasing the application time to 30 minutes elevated the amount of HP inside the pulp chamber for all groups (p = 0.003), except for PL (p > 0.05). When applied for 30 min all bleaching varnishes showed higher color change (ΔWID) when compared to 10 min (p = 0.04).ConclusionsFor all bleaching varnishes evaluated, PolaLuminate applied for 30 min showed lower penetration into the pulp chamber and higher bleaching effects.Clinical SignificanceThe use of bleaching varnishes seems promising for teeth bleaching, but it varies according to user product and protocol.

“…In‐office dental bleaching has become increasingly popular for its ability to deliver impressive tooth whitening results in a single session, 1 significantly improving patients' quality of life 2 . This technique involves using high concentrations of hydrogen peroxide, which are supplied in two separate vials that need to be mixed just before application 3,4 …”

ObjectiveThis study aims to assess hydrogen peroxide (HP) penetration into the pulp chamber, color change (CC), physical–chemical properties, and material wastage (MW) and material used (MU) in mixing tips when using in‐office bleaching gels with two different mixing tips.Materials and MethodsForty teeth were divided into five groups (n = 8) based on the bleaching gels used (Pola Office +37.5% [PO+] and Whiteness HP Automixx Plus 35% [AM+]) and the mixing tip types (T‐Mixer and Helical). A negative control group was treated with ultra‐purified water. HP concentration was measured using UV–Vis, and CC was evaluated with a digital spectrophotometer. Initial concentration, pH, and viscosity were measured through Titration, a Digital pH meter, and Rheometer, respectively. MW and MU were measured using a precise analytical balance. Statistical analysis included two‐way ANOVA, Tukey's, and Dunnett's test (α = 0.05).ResultsA higher HP concentration was observed with PO+ with the Helical mixing tip in comparison with AM+ (p = 0.01). No significant differences in CC or MU were found for different mixing tips (p = 0.001). The T‐mixer mixing tip resulted in significantly less MW (p < 0.00001) and improved mixture homogeneity and viscosity.ConclusionsUtilizing a T‐mixer with self‐mixing bleaching gels achieves comparable CC while reducing MW. Moreover, it decreases HP penetration when using PO+.Clinical SignificanceFor the application of a self‐mixing in‐office bleaching gel, a T‐mixer mixing tip should be recommended, as it reduces the penetration of hydrogen peroxide into the pulp chamber when using PO+, while also minimizing gel wastage.
