Filter by:Objectives: This study will determine the clinical efficacy of bleaching agent 37% carbamide peroxide compared to 35% hydrogen peroxide on the change of color scores in anterior superior teeth, in-office bleaching technique after 7, 14 and 37 days; and the Risk to the tooth sensitivity before, during and 24 hours after the procedure. Materials and Methods: Fifty patients will be selected for this single-blind, parallel, randomized-controlled clinical trial. The whitening treatment with 37% carbamide peroxide or 35% hydrogen peroxide (control) will be carried out in a single application of 45 minutes for two sessions with a 7-day interval. The sensitivity level will be assessed before, during and 24 hours after the procedure using verbal and analogic visual analogue (VAS) scales. Color alteration will be assessed by a bleach guide scale 7 days after each session and 30 days after the last session. Relative risk to sensitivity will be calculated and adjusted by session; while comparison of overall risk will performed by McNemar's test. Data on the sensitivity level for both scales will be subjected to the Mann-Whitney tests (α = 0.05). The color change will be measured with a spectrophotometer using the CIE L * a * b * and the L*, a * and b * parameter delta data, and ΔE and Δ00, will be individually subjected to two-way repeated measures ANOVA test to compare the two bleaching techniques at each evaluation time (α = 0.05).
The purpose of the study is to evaluate the efficacy of Sensi-StopTM strips (Procter & Gamble™) on the relief of dentinal hypersensitivity. In other words, do Sensi-StopTM strips (Procter & Gamble™) reduce or eliminate cold sensitivity in teeth? In addition, the investigators will evaluate whether there is a difference in the Sensi-StopTM strip (Procter & Gamble™) effectiveness when the product is placed by a dental professional compared to self-placement by the person with sensitive teeth. This product is not experimental.
