1. Preemptive use of etodolac on tooth sensitivity after in-office bleaching: a randomized clinical trial
Abstract Purpose: This study determined the effectiveness of the preemptive administration of etodolac on risk and intensity of tooth sensitivity and the bleaching effect caused by in-office bleaching using 35% hydrogen peroxide. Material and methods: Fifty patients were selected for this tripleblind, randomized, crossover, and placebo-controlled clinical

2. Effectiveness of a new non-hydrogen peroxide bleaching agent after single use - a double-blind placebo-controlled short-term study
Abstract Tooth whitening represents perhaps the most common aesthetic procedure in dentistry worldwide. The efficacy of bleaching depends on three aspects: bleaching agent, bleaching method, and tooth color. Objective: This in vivo study aimed to examine whitening effects on frontal teeth of the upper and lower jaws using an over-the-counter (OTC) non-hydro

4. Effectiveness of nano-calcium phosphate paste on sensitivity during and after bleaching: a randomized clinical trial
The study aimed to evaluate the effectiveness of in-office bleaching and associated tooth sensitivity on application of nano-calcium phosphate paste as desensitizing agent. Bleaching was performed with 35% hydrogen peroxide gel in 40 patients who were randomly divided into placebo and nano-calcium phosphate paste groups. Bleaching efficacy (BE) was evalua

5. In-office bleaching effects on the pulp flow and tooth sensitivity – case series
Laser Doppler flowmetry (LDF) is a noninvasive method capable of evaluating variations in pulp blood flow (PBF) and pulp vitality. This method has thus far not been used to assess changes in blood flow after in-office bleaching. The aim of this case series report was to measure changes in PBF by LDF in the upper central incisor of three patients submitted to

6. The influence of desensitizing dentifrices on pain induced by in-office bleaching
The purpose of this study was to evaluate whether the use of desensitizing dentifrices used 15 days prior to and after in-office tooth bleaching could eliminate or reduce tooth sensitivity. After institutional review board approval and informed consent, 45 subjects were selected and divided into 3 groups according to the dentifrice selected: Colgate Total (C

7. AVALIAÇÃO DAS DIFERENTES TÉCNICAS DE CLAREAMENTO DENTAL DE CONSULTÓRIO: EFETIVIDADE, SENSIBILIDADE PÓS-TRATAMENTO E EFEITOS SOBRE O COMPLEXO DENTINO-PULPAR / Assessment of different in-office tooth bleaching techniques: Effectiveness, sensitivity post-treatment and effects on the pulp-dentin complex
The use of bleaching gels with low hydrogen peroxide (HP) concentration, as well as the reduction of application times or its association with calcium-containing agents may be clinical approaches to reduce the amount of HP that reaches the pulp tissue to cause local damage. However, only a few data have been published about the pulp response of human teeth s

9. CIE L*a*b*: comparison of digital images obtained photographically by manual and automatic modes
The aim of this study was to analyze the color alterations performed by the CIE L*a*b* system in the digital imaging of shade guide tabs, which were obtained photographically according to the automatic and manual modes. This study also sought to examine the observers' agreement in quantifying the coordinates. Four Vita Lumin Vaccum shade guide tabs were used

10. Effectiveness of carbamide peroxide and sodium perborate in non-vital discolored teeth
OBJECTIVE: To evaluate the efficacy of 16% carbamide peroxide gel (CP16%), tetrahydrate sodium perborate (SP) and mixture (CP16% + SP), in walking bleaching of non-vital discolored teeth. MATERIALS AND METHODS: Sixty single-rooted human premolars with intact crowns were used and initial color was assessed using Vita shade guide and standardized photos. The t

11. In vitro assessment of intracoronal bleaching using 2% chlorhexidine gel associated to different bleaching agents / Estudo "in vitro" da associação da clorexidina gel 2% a agentes clareadores utilizados durante o clareamento dental interno
Non-vital tooth bleaching is a conservative esthetic treatment for endodontically treated discolored teeth. It is effective and relatively inexpensive. The purpose of this study was to evaluate ?in vitro? the association of sodium perborate + 2% chlorhexidine gel comparing with sodium perborate + distilled water; sodium perborate + 30%hydrogen peroxide (H2O2

12. "Estudo colorimétrico da translucidez de materiais restauradores odontológicos" / Colorimetric Study of the translucency of restorative odontologic materials.
Quando um dente anterior é restaurado toda uma técnica de proteção ao tecido remanescente e a recuperação funcional do elemento dental podem ser comprometidas se a escolha da cor do material restaurador empregado não for adequada. A familiaridade com as teorias da cor e da interação da luz com a matéria pode ajudar na tarefa de escolha da tonalidad
