View clinical trials related to Dentin Sensitivity.
Filter by:This is a randomized, triple-blind, placebo-controlled study. 51 subjects with a confirmed diagnosis of dentin hypersensitivity were randomized to one of three treatments: Arginine based toothpaste, strontium acetate based toothpaste , or placebo. Treatment will be done at baseline then patients will use the toothpaste at home twice per day by using soft bristled tooth brush and the given dentifrice using modified stillmans method as explained by examiner. Standard test stimuli is calibrated short blast of air syringe, will be applied to sensitive dentin surfaces. Subjects recorded the intensity of sensitivity in response to stimulus on a visual analog scale at baseline, and after 1 week, 2 weeks and 3 months.
To investigate the effects of desensitizing agents on the dental bleaching process, testing the hypothesis that they may prevent dental sensitivity.
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.
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
Clinical randomized, triple-blind, used to measure the level of tooth sensitivity on volunteers using a modified virtual analog scale (VAS). Sixty-six volunteers will be selected and recruited, following inclusion criteria and pre-established exclusion. All volunteers will be guided and sign a term of clarification and consent. Volunteers will be randomly divided into two groups: the control group to receive placebo capsules and application of desensitizing gel containing 6% potassium nitrate and 0.10% fluoro- (conventional treatment) and the experimental group will receive the anti-inflammatory corticosteroids (dexamethasone, capsule - 8mg) and application of a placebo gel. Patients will be treated in two clinical sessions with an interval of 7 days (one week) between them. The protocol for use of the product is as follows: The volunteers in the experimental group will receive six capsules of dexamethasone 8 mg each to be administered orally, initially two days before the first bleaching query as follows: 8 mg (1 capsule) 9 am in the morning two days before the first clinical session whitening; 8 mg (1 capsule) the 9 am to 1 day before the first practice session whitening, 8 mg (1 capsule) to 9 am on the day of the first practice session of whitening. After 7 days (one week), the same protocol will be held for the second and final practice session office bleaching.
A proof of principle single-centre, randomized-controlled, examiner-blind, two treatment group study to investigate the efficacy of an experimental 15% w/w dissolvable strip in relieving dentine hypersensitivity (DH) after a single application and up to 4 hours after application compared to no treatment.
The aim of this study is to compare the efficacy of dentine hypersensitivity reduction using in office paste formula containing nanoHydroxyapatite with the commercially available fluoride (duraphat) and a placebo in treating hypersensitivity in a single visit.
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 aim of this study is through a randomized clinical trial, double blind, splith-mouth, evaluate the various types of protocols and clinical efficacy in the reduction or even elimination of dentinal hypersensitivity by the agents Desensibilize KF - FGM Dental Products, Clinpro - 3M Company, Minnesota - USA, Photon Laser III - DMC, Brazil, Desensibilize KF and laser, Desensibilize KF and Clinpro, laser and Clinpro and the association of all products. Data will be collected, tabulated and submitted to statistical analysis.
Up to date, devices capable of delivering controlled, calibrated, non-contact cold air stimuli in a MR environment are unavailable for quantitative sensory testing. This project therefore aimed at designing and constructing a novel MR-compatible, computer-controlled cold air stimulation device that produces air puffs in a broad flow and cold temperature range. By means of this device, detailed psychophysically testing and subsequent brain scanning of dentine hypersensitivity (DH) subjects will be possible to gain new insights about DH mechanisms.
