“…The characteristics of the 24 selected studies are described in Table 1 (methodology) and Table 2 (results). Sixteen randomized clinical trials [ 1 , 2 , 19 – 23 , 30 – 38 ] and 8 clinical trials [ 39 – 46 ] were selected. In total, 1197 subjects were exposed to home bleaching using different bleaching agents such as HP at concentrations of 3% [ 35 ], 5% [ 20 ] 5.3% [ 20 ] 6% [ 21 , 22 , 34 , 43 ], 7.5% [ 21 , 40 ], and 10% [ 1 , 21 ] and CP at concentrations of 10% [ 1 , 2 , 19 , 22 , 23 , 30 – 33 , 36 – 39 , 42 – 46 ], 15% [ 34 , 41 , 46 ], 16% [ 23 , 30 , 38 ], 20% [ 46 ], and 28% [ 37 ].…”

“…Patients seeking an attractive smile have been increasing significantly, especially in terms of tooth color [ 1 ]. Dental bleaching is considered the treatment of choice to improve patient satisfaction in terms of tooth discoloration, due to its non-invasive approach and low cost compared to other cosmetic dentistry procedures [ 2 ]. Many types of color problems can affect the appearance of teeth, and the causes of tooth discoloration must be carefully evaluated to establish a correct diagnosis [ 3 , 4 ].…”

Objectives The aim of this systematic review was to evaluate the prognosis of at-home dental bleaching using low concentration bleaching products. Materials and methods This review was conducted was performed following the recommendations of the 2020 PRISMA statement and was registered in the International Prospective Register of Systematic Reviews (PROSPERO-CRD42022360530). The PICO question was “What is the prognosis of home teeth whitening treatment?”. An advanced electronic search was made in three databases: PubMed, Web of Science, and Embase. Results The database search led to the retrieval of 225 articles. After elimination of duplicate references, the titles and abstracts of the articles were analyzed with respect to the eligibility criteria, and 24 studies were included for the development of the systematic review. Conclusions Most authors state that the color remains stable between 1 and 2.5 years regardless of the type of bleaching agent or the forms of administration, and color stability in cases of severe discolorations presents a higher degree of recurrence. Clinical relevance Given the growing demand for dental cosmetic treatments, the following systematic review may aid the clinician’s continuing education and evidence-based practice by providing knowledge on the field of at-home dental bleaching agents and their long-term effects.

“…Using the same parameters of L*, a*, and b* parameters, we could calculate color change using the conventional CIELab 76 system (ΔE ab ), the CIEDE2000 system (ΔE 00 ), and the whiteness index for dentistry (ΔWI D ) [46][47][48]. The CIEDE2000 system has been more recently employed, as it better estimates the visual perception of color [68]. The whiteness index provided more information on the direction of the bleaching effect [48] and has been added to recent RCTs about bleaching [21,50,53,66].…”

Objectives To evaluate the risk and intensity of tooth sensitivity (TS), and the efficacy of in-office bleaching after applying an experimental desensitizing gel composed of 10% calcium gluconate, 0.1% dexamethasone acetate, 10% potassium nitrate, and 5% glutaraldehyde. Material and methods In a split-mouth, double-blind, placebo-controlled study, 50 participants had their upper hemiarches randomized into experimental and placebo groups. Desensitizing and placebo gels were applied for 10 min before in-office bleaching (35% hydrogen peroxide, 1 × 50 min; two bleaching sessions; 1-week interval). TS was recorded immediately after bleaching, 1, 24, and 48 h after each session, with a 0–10 visual analogue scale (VAS) and a five-point numerical rating scale (NRS). The color was recorded in all groups at baseline, 1 week after each session, and 1 month after the end of bleaching using shade guide units (ΔSGUs) and a spectrophotometer (Δ E ab , Δ E 00 , and ΔWI D ). Results Most participants (96%) felt some discomfort during treatment regardless of the study group. The odds ratio for pain was 0.65 (95% CI 0.1 to 4.1; p = 1.0). The intensity of TS did not differ between groups ( p > 0.31), and it was only 0.34 VAS units lower in the experimental group. A significant color change occurred in both groups regardless of the group. Conclusions The desensitizing experimental gel applied before in-office bleaching did not reduce the risk and the intensity of TS and did not affect color change. Clinical relevance Although the experimental desensitizing agent with varying mechanisms of action did not jeopardize the color change, it did not reduce the risk or intensity of in-office bleaching. Clinical trial registration number RBR-7T7D4D.

“…Ele foi originalmente projetado para ser usado durante a noite (6 a 8 h), porém, o tempo de aplicação recomendado na literatura para baixas concentrações de peróxido de carbamida 10-16% varia de 1h a 4h (Gökay et al,2000;Cavalli et al 2019). O peróxido de carbamida 10% é o agente de menor concentração para aplicações caseiras, sendo indicado seu uso por 4h para que haja efetividade de clareamento, menor sensibilidade e se evite efeitos de citotoxicidade (Cavalli et al 2019;Goettems et al, 2021;Meireles et al, 2022).…”

“…Nesta técnica, o paciente utiliza uma moldeira de clareamento contendo o gel por poucas horas por dia durante duas semanas ou mais (Basting, 2001;Basting, 2012;Ghanbarzadeh, 2015;Meireles et al, 2022).…”
