“…The same happens when nitrogen‐doped titanium dioxide is combined with low concentrations of oxidant agents . Other compounds like strontium chloride and potassium nitrate combined with fluoride do not interfere with the whitening effect, but they improve the process reducing the morphological changes in the enamel …”

Objective The aim is to review the most important aspects about tooth whitening treatments, their side effects, and the new emerging approaches to overcome them. Overview This review is focused on origin of tooth stains, the whitening systems and their chemistry, their side effects, and the new approaches. The search of bibliography of the period 1965‐2018 has been analyzed. Conclusions Tooth whitening has become one of the most requested dental treatments by the public. Tooth stains are classified according to their origin into two categories: intrinsic and extrinsic. The whitening systems are generally organized into two classes: in‐office and at‐home products. Most of the whitening systems use hydrogen peroxide as the active oxidative agent to degrade the organic compounds that cause stains. The concentration ranges depending on the treatment, and it may be applied directly or produced in a chemical reaction from carbamide peroxide that is more stable. Besides its popularity, tooth whitening still has some side effects being tooth hypersensitivity the most common. In order to decrease these side effects, new treatments are constantly in renewal processes. Clinical Significance Despite all the data and new strategies known about tooth whitening, there are many aspects that are not totally fully understood and methodologies that are not completely effective. Therefore, the development of effective, efficient, and long‐lasting whitening treatments is still necessary.

“…Clinically, a desensitizer agent containing fluoride and potassium nitrate attenuates the risk and intensity of tooth sensitivity 19 during bleaching by obstructing dentin tubules and preventing depolarization of nerve fibers 33 . Even though this study presents the inherent limitation of an in vitro design, it demonstrated that the desensitizer might positively impact the bond strength of postponed procedures.…”

Aim: This study evaluated the effect of a desensitizer agent (DES) during bleaching with 10% carbamide peroxide (CP) on enamel microshear bond strength (μSBS). Methods: Sixty bovine incisors were obtained and randomly distributed into groups (n=15): (C) Control: no desensitizing or bleaching, (DES) desensitizing gel application, (CP) bleaching with 10% CP and (CP/DES) bleaching with 10% CP combined with DES. Bleaching was performed for 6 h/day for 14 consecutive days. DES was applied for 8 h only on the 7th and 14th days of therapy. Specimens were stored in artificial saliva among the CP or DES applications and submitted to μSBS testing at three postrestoration times (n=5): 24 h, 7 days, and 14 days after bleaching using a universal testing machine. Failure modes were observed under a stereomicroscope. Data were analyzed by two-way ANOVA and Tukey’s test (α=5%). Results: Immediately after bleaching (24 h), CP promoted lower μSBS than the C and DES groups (p<0.05) but with no differences from the CP/DES. μSBS increased in the DES, CP, and CP/DES groups (p<0.05) when bonding was performed for 7 or 14 days elapsed from bleaching. CP/DES exhibited the highest μSBS among the groups 14 days after bleaching (p<0.05). Cohesive failure in enamel was predominant in the CP groups, while adhesive failure was mostly observed for the other groups. Conclusion: The use of a desensitizer during at-home bleaching maintained the enamel immediate bond strength, and its application favored bonding when the restoration was delayed for 14 days.

“…Acredita-se que a menor remineralização obtida neste grupo seja atribuída, portanto, ao nitrato de potássio, visto que os íons potássio, embora sejam componentes ativos na prevenção da sensibilidade dentária em dentes vitais (dessensibilização), não desempenham papel efetivo na remineralização dentária. 26 Há relatos sobre a efetividade de proteção de cremes dentais à base de zinco-hidroxiapatita (Zn-HAP) e de caseína fosfato de cálcio amorfo (CPP-ACP) sobre o esmalte dentário, 15,2,13 em que a adição de flúor pode potencializar a remineralização. 14 Estudos mostram que a CPP-ACP pode estar associada à uma melhor remineralização das lesões de cárie precoce em relação aos fluoretos.…”

Introdução: A erosão dentária consiste na perda progressiva de tecido duro de um dente por processos químicos que não envolvem ação bacteriana. Objetivo: Avaliar, através da microdureza superficial, a remineralização do esmalte dentário após o tratamento com diferentes agentes remineralizadores. Material e Métodos: Foram confeccionados 25 blocos de esmalte dentário a partir de incisivos humanos. Os corpos de prova foram divididos aleatoriamente em cinco grupos (n=5), de acordo com o tratamento remineralizador empregado. No grupo 1 (G1), controle positivo, os corpos de prova não desmineralizados foram mantidos em água deionizada. No grupo 2 (G2), controle negativo, após desmineralização com ácido fosfórico a 37% por 5 minutos, os corpos de prova foram mantidos em água deionizada. Nos grupos 3 a 5, após desmineralização com ácido fosfórico a 37%, foram aplicados, respectivamente, gel de fluoreto de sódio a 2% (G3), creme dental à base de silicato de cálcio e fosfato de sódio (G4) e creme dental à base de fluoreto de sódio e nitrato de potássio a 5% (G5). Todos os corpos de prova foram submetidos ao teste de microdureza superficial Knoop. Os dados obtidos foram tabulados e submetidos à análise de variância (ANOVA) e teste de Tukey (significância de 5%). Resultados: Os grupos G2 (150,39±26,32), G3 (184,66±9,05) e G5 (279,26±20,77) apresentaram diferenças significativas quando comparados ao grupo controle positivo G1 (331,93±13,82) (p<0,01). Em relação ao grupo controle negativo G2 (150,39±26,32), diferenças significativas foram encontradas quando comparados aos grupos G1 (331,93±13,82), G4 (365,99±18,97) e G5 (279,26±20,77) (p<0,01). Conclusão: Pode-se observar a eficácia de cremes dentais a base de silicato de cálcio e fosfato de sódio no potencial remineralizador do esmalte dentário.
