“…An oxi‐reduction reaction is responsible to degrade the hydrogen peroxide into reactive oxygen species (ROS, i.e., hydroxyl and perhydroxyl). (5) These molecules are responsible for cleavage of the chromogens (the molecules responsible for dentin staining), which, in turn, would either be decomposed into smaller and lighter molecules or eliminated from the tooth (3,5).…”

This review compiles the literature on the antioxidants used after tooth bleaching with either low or high‐concentrated carbamide and hydrogen peroxide to recover the bond strength. Antioxidants used in bleached teeth are mainly natural and non‐enzymatic, except for catalase. Commonly, antioxidants are applied to remove any reactive oxygen species (ROS) residues left from bleaching gels, which adversely affect adhesive procedures, such as restorations or orthodontic brackets bonding. Even though sodium ascorbate, the most thoroughly investigated antioxidant, showed the most efficient bond strength recovery at 10% concentration, its performance depends on the type of solution and the application time. Natural extracts, such as proanthocyanidins and green tea, showed satisfactory results in the reversal of bond strength at 5% and 10% concentrations, respectively. Sodium ascorbyl phosphate, α‐tocopherol, and catalase exhibited promising results, but further research is required. The adhesive system type plays an important role in the outcome of enamel bond strength after the antioxidant application. The postponement of either restorations or orthodontic brackets cementation following bleaching procedures seems to be efficiently replaced by antioxidant application prior to bonding procedures. However, the efficacy of using an antioxidant to recover bond strength depends on its type and application time.

“…On the other hand, disadvantages of in-o ce bleaching are increased tooth sensitivity and less stable bleaching outcomes. [132,135] There also have been concerns regarding the safety of higher concentrations of in-o ce bleaching products which could diffuse into the pulp chamber [137] resulting in pulpal tissue changes and post-treatment sensitivity. [138][139][140] In teeth with thin enamel, such as mandibular incisors, it potentially could lead to pulpal necrosis.…”

Evidence-based fact checking for selective procedures in restorative dentistry

Objectives: Similar to other dental specialties, there are many clinical procedures in restorative dentistry that may or may not be supported by good evidence. Thus, the effectiveness of these procedures is uncertain. The aim of this paper is to reduce this knowledge gap by critically inspecting selective procedures in restorative dentistry and exploring if these well-established or widely advocated treatment modalities are necessary for improving treatment outcomes based on the best available evidence.Materials and Methods: A MEDLINE search was conducted to identify research on selective procedures while focusing on clinical trials and systematic reviews. Due to their practical relevance in the decisionmaking process, cost-effectiveness analyses were also included.Results: Mixed results were identi ed regarding the included interventions. Some procedures had adequate evidence supporting them while others were mostly based on beliefs.Conclusions: A critical review of the available literature indicates that some common restorative procedures lack adequate support from high quality research evidence.Clinical Relevance: In the era of evidence-based dentistry, clinical decision-making should rely on best available evidence rather than expert opinion. This will ensure consensus among stakeholders and improve treatment outcomes.

“…This procedure is accomplished by two alternative techniques: (I) home-applied bleaching, using low-concentration peroxide agents such as 3-10% hydrogen peroxide (HP) or 10-20% carbamide peroxide (CP); and (II) ino ce bleaching using high concentration peroxide agents (35-40% HP or CP) [3,4]. Both processes involve an oxidizing agent, HP or CP, responsible for the release of reactive oxygen species (ROS), which will diffuse into the enamel interprismatic spaces for the cleavage of pigmented molecules [5][6][7].…”

Objective To evaluate color change, surface roughness, microhardness, and morphology of enamel submitted to bleaching with 35% hydrogen peroxide (HP) gels associated with different concentrations of bioglass 45S5 (BG).Methods Enamel blocks (n = 10) were submitted to a positive control (PC): 35% HP bleaching; HP_BG: HP associated with a gel containing BG at concentrations of 0, 2.5, 5, 7.5, 10 wt% and negative control (NC), no treatment in 3 sessions of 40 min each and 7 days apart. The blocks were kept in artificial saliva up to 14 days after bleaching. Color change (ΔE00), color parameters (ΔL, Δa, Δb), roughness average (ΔRa), and surface microhardness were evaluated at baseline (T0), after 24h (T1), and 14 days elapsed from bleaching treatment (T2). The percentage of surface hardness loss (%SHL) was calculated and the enamel was characterized at T2 by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Data were subjected to ANOVA and Tukey test (α = 0.05).Results No differences in ΔE00 and Δb were observed among HP-containing groups, regardless of the BG concentration (p > 0.05). Additionally, no differences were noted in ΔRa, ΔL, and Δa among the groups (p > 0.05). However, BG incorporation into the bleaching gels prevented enamel mineral loss in comparison to PC immediately after bleaching treatment (T1, p < 0.05). At T2, 10% BG was the only group to keep enamel mineral content (p < 0.05). Conclusion: The addition of BG did not affect the HP bleaching efficacy and the incorporation of 10% BG into the HP bleaching agent exhibited a positive remineralizing effect.Clinical Relevance: It was found with BG has the potential to reverse the harmful effects on the dental surface during the bleaching protocol.
