ABSTRACT
Abstract Objective Our study aims to compare the efficacy and tooth sensitivity following in-office (35% hydrogen peroxide) or at-home (10% carbamide peroxide) bleaching treatments both preceded by 2% potassium nitrate (2%KF) desensitizing gel. Methodology 130 volunteers were randomly allocated to a) in-office bleaching and a placebo at-home protocol; or b) in-office placebo and at-home bleaching treatment. 2% KF was applied for 10 min before both treatments. Objective color evaluation was performed (spectrophotometer CIEL*a*b* system and CIEDE2000) to calculate the color change (ΔE00). Subjective evaluation was performed using the VITA classical shade guide followed by shade variation (ΔSGU) at the beginning and end of bleaching treatment and 2 weeks post-bleaching. Tooth sensitivity was daily recorded using a Likert scale varying from 1 (no sensitivity) to 5 (severe sensitivity). Analysis was carried out using non-parametric tests. Results Regarding the color change, at-home bleaching resulted in significant color improvement compared to in-office treatment for the parameters Δb* (p=0.003) and Δa* (p=0.014). Two weeks post-bleaching, the at-home treatment resulted in significant color improvement compared to in-office treatment for the parameters Δb* (p=0.037) and ΔE00 (p=0.033). No differences were observed in either ΔSGU parameters. Concerning sensitivity, patients treated with in-office bleaching reported more tooth sensitivity than the at-home group only on the first day after bleaching started, without significant differences in the other periods evaluated (p>0.05). Conclusions At-home and in-office bleaching, preceded by a desensitizing agent, were effective for vital teeth bleaching and 10% carbamide peroxide produced a higher whitening effect than 35% hydrogen peroxide in the short time evaluation. Tooth sensitivity rates were similar for the two techniques tested.

Pacientes que apresentam alterações na estrutura dos elementos dentais que refletem na estética do sorriso estão em constante busca por procedimentos que reabilitem forma, função e principalmente estética. A amelogênese imperfeita é caracterizada por alterações na quantidade e/ou qualidade do esmalte dental e atinge tanto a dentição decídua quanto a permanente, interferindo na estética do sorriso. Para reabilitar pacientes com amelogênese imperfeita, diversos tratamentos estão disponíveis. Desse modo, o presente relato de caso clínico tem por finalidade demonstrar a reabilitação estética em um paciente com amelogênese imperfeita através do uso de laminados cerâmicos minimamente invasivos...
Patients presenting changes of tooth structure which impairs the aesthetics of the smile are consistently searching for procedures to restore form, function and mainly their aesthetics. Amelogenesis imperfecta is a disorder characterized by changes in the amount and/or quality of tooth enamel, affecting primary and permanent dentitions. Several treatments are available to rehabilitate patients with amelogenesis imperfecta. The aim of this case report is to demonstrate the aesthetic rehabilitation of a patient with amelogenesis imperfecta using minimally invasive porcelain laminate veneers...

A demanda por tratamentos estéticos que buscam um sorriso com aparência natural e com adequada longevidade clínica tem aumentado tanto por parte dos pacientes como por parte dos profissionais. O esclarecimento e a disponibilidade de novas técnicas fizeram surgir a preocupação por tratar esteticamente, no entanto mediante tratamentos minimamente invasivos, que não gerem danos à estrutura dental. Nesse contexto, surgiram os laminados cerâmicos minimamente invasivos. Este artigo relata um caso clínico de remodelação estética de dentes anteriores com manchamento por tetraciclina, através de laminados cerâmicos minimamente invasivos...
The demand for aesthetic treatments searching a natural-looking smile and longevity is increasing by patients and dentists. The knowledge and availability of new techniques increased the desire for aesthetic treatments that could be minimally invasive and not generating damage to tooth structure. In this context, minimally invasive ceramic laminates appeared. This paper reports the aesthetic reshaping of anterior teeth with tetracycline staining using minimally invasive ceramic laminates...
