Active clinical trials for "Dentin Sensitivity"

To compare the efficacy of two commercially available in-office desensitizing agents (Fluoraphat Pro and VivaSens®), in the treatment of dentinal hypersensitivity.

Objective: This randomized, double-blind, parallel, placebo-controlled clinical trial aims to evaluate the effect of propolis with two distinct concentrations (10% and 15%), and the impact on volunteers' quality of life. Materials and methods: Volunteers meeting the inclusion and exclusion criteria will be randomized and allocated into three groups: Group 1- placebo - toothpaste without active ingredient, Group 2- toothpaste with 10% propolis and Group 3. - toothpaste with 15% propolis. Number of teeth will be used as sample unit, totaling 22 teeth per group. Volunteers will receive oral hygiene instruction with guidance to brush their teeth three times a day with toothpaste corresponding to the groups in which they will be allocated for 30 days. The evaluation of dentin hypersensitivity will be performed with three (3) evaluation times: baseline (immediately before the beginning of treatment), 15 and 30 days, through tactile and evaporative stimuli, using the visual analog scale (VAS). The self-reported evaluation of the volunteers will be done through a questionnaire before the beginning and after one month with the completion of the research to determine the impact of treatment on their quality of life. The data regarding HD in VAS, if present normal distribution, will be used Two-way analysis of variance (ANOVA) with Tukey's post hoc for comparison between treatments. However, if the data show anormal distribution, Friedman to compare the different times in the same group (intra group), and Kruskal Wallis to make the comparison between groups (inter group). To evaluate the QEHD ordinal data, Wilcoxon and Mann-Whitney tests will be used. Bioestat 5.3 (Belém, Pará, Brazil) will be used, considering an alpha level of 5%.

Fluoridated desensitizers the frequently used for the treatment of dentin hypersensitivity (DH) with Iontophoresis. This study aimed to evaluate and compare the immediate and long-term effects of 10% Propolis with 2% sodium fluoride and 1.23% acidulated phosphate fluoride when applied along with Iontophoresis for the treatment of cervical dentin hypersensitivity (DH). Single-center, parallel, and double-blinded randomized clinical trials were conducted on systemically healthy patients, complaining about DH, with at least two sites. 10% propolis, 2% Sodium Fluoride and 1.23% Acidulated Phosphate Fluoride were used as desensitizers along with the Iontophoresis. After applying specific stimuli any decrease in DH was measured at baseline before and after application, on the 14th day after use, and at 28th-day post-intervention time intervals.

Background: The administration of the intra-oral drugs was not capable of reducing this side effect, maybe the use of two analgesics may to present better analgesic effect to avoid the bleaching-induced tooth sensitivity (TS). Methods: A triple-blind, parallel-randomized clinical trial was conducted with 114 health patients who received either a placebo or an association of ketorolac tromethamine/acetaminophen. The first doses of two analgesic (Acetaminophen 750 mg/ Ketorolac Tromethamine 10 mg) or placebo was administered 1 h before the in-office bleaching (35% hydrogen peroxide), and extra doses were administered every 8 h for 48 h. The TS was recorded using 0-10 visual analog scale and a 0-4 numeric rating scale in different periods: during bleaching and from 1 h up to 6h, from 12 h up to 18h, from 18h up to 24 h, from 24h up to 48 h post-bleaching. The color was measured before and one month after dental bleaching with a visual shade guide Vita Classical, Vita Bleachedguide 3D-Master and spectrophotometer Vita Easyshade (Vita Zahnfabrik). The absolute risk of TS was evaluated by Fisher's exact test. Data of TS intensity with NRS scale of the two groups were compared with Mann-Whitney and Friedman tests, while data from the VAS scale were evaluated by two-way repeated measures ANOVA and Tukey's test for pairwise comparison. The color changes between groups were compared using a Student t-test (α = 0.05).

This pilot study will evaluate the safety and effectiveness of a marketed sensitivity strip on existing dentinal hypersensitivity compared to a marketed sensitivity pen.

This single center study will investigate the efficacy of an experimental stannous fluoride containing dentifrice in relieving DH compared with a standard fluoride dentifrice after short term use.

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.

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.

Ibuprofen has been recognized as anti-inflammatory and analgesic. The purpose of this study is to determine the effect of ibuprofen 400 mg on tooth sensitivity (TS) caused by in-office bleaching. Methods: 30 health adults who received either placebo or ibuprofen. The drugs were administered 1 hour prior to the bleaching and will be prescribed 5 doses every 8 hours during 48 hours. For bleaching will be used 35% hydrogen peroxide gel. The tooth sensitivity will be recorded for up and lower arc on two scales: VAS (visual analogic scale) and 0-4. The shade evaluation will be performed before and 30 days after bleaching with visual shade guide and spectrophotometer.

The purpose of this exploratory study is to compare the treatment effect on dentinal hypersensitivity of a tubule occluding dentifrice as measured by Schiff and Tactile sensitivity. This proof of concept study will compare the test dentifrice with three other treatment groups.
