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%).
Teeth sensitivity is the most popular symptom when using At-Home tooth whitening. Tri calcium phosphate containing pastes may affect the efficacy and postoperative sensitivity associated with At-Home vital tooth whitening using 20% carbamide peroxide
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.
This is a three year single site clinical evaluation of a FDA approved (510(k):K100062) lesion penetrating resin used to infiltrate and hamper progression of proximal carious lesions. The purpose of this study is to compare lesion progression infiltrated with (Icon, Hamburg, Germany) to a similar sized lesion in the same patient treated with a placebo. The study is designed as a randomized, controlled, prospective clinical trial with a three year follow-up evaluation period. The clinical site will enroll 150 subjects (in the age range of 19 years or older) with 2 study lesions. The patients will be evaluated at six time points over a period of 3 years. Lesion status and caries risk will be monitored at 6-month intervals, while radiographic evaluation will be conducted at 12-month intervals at 1-, 2- and 3-year recall visits.
