Filter by:The aim of this clinical study is to evaluate the efficacy and dental sensitivity associated with Combined Bleaching Technique (in-office + at-home) varying in-office bleaching application under two different time protocols, and dentifrice containing arginine 8% and carbonate calcium use. One hundred eight participants who meet the study inclusion criteria will be selected. The desensitizing agent used will be a dentifrice containing 8% arginine and calcium carbonate. In each evaluation will be determined: tooth sensitivity and color. The data collected will be submitted to the factorial statistical analysis for evaluation of color and chi-square test for tooth sensitivity (α = 5%).
This randomized, controlled clinical trial, triple-blind, split-mouth type was conducted aiming to assess the absolute risk of sensitivity with and without sonic activation of a desensitizing gel previously to the in-office bleaching in adults.
Evaluating the effect of a desensitizing agent on post-bleaching hypersensitivity.
Study title: The Efficacy and Safety of tooth bleaching procedure using Y10 Whitening toothpaste and RF current The Device: The Brighttonix Y10 Tooth Whitening system is indicated for use in painless non-invasive tooth whitening treatments. Design: Single center, randomized, controlled, double blind, two-arm, prospective clinical study. Follow up visits at 7 days (phone visit), 12 weeks and 26 weeks.
This study aims to evaluate the effects of prior use of non-steroidal anti-inflammatory Naproxen on risk and level of tooth sensitivity caused by in-office bleaching procedures.
Bleaching protocol In each session, volunteers received prophylaxis with pumice powder and water. Then, gingival tissue was protected using a light-cured resin gum barrier applied according to the manufacturer's instructions (Lase Protect - DMC, São Carlos, SP, Brazil). Both bleaching agents were prepared by mixing hydrogen peroxide and thickening compounds according to the manufacturer's instructions (with 3 peroxide drops for 1 drop of thickener). The resultant gels were distributed uniformly on the upper hemiarcade surfaces of the teeth. A total of 8 teeth between the first premolars were bleached for each patient. In each bleaching session, the bleaching gels were applied twice for 12 minutes each. In each application, the surface of the gel was light activated with continuous irradiance for 12 minutes using LED/laser light with a total power of 1800 mW (Whitening Lase Plus - DMC Equipamentos, São Carlos, SP, Brazil). Three bleaching sessions were completed for the patients, and the interval between sessions was 7 days
