NCT06802614
Tooth bleaching is widely used to treat the colors of teeth. This study compares the efficiency of two experimental bleaching gels, with and without nanoparticles, and with and without light activation versus two commercial bleaching products of low and high concentrations. The objective is to evaluate tooth color change, sensitivity, and patient satisfaction in patients with moderate yellowing of their teeth. Methods: This is a randomized controlled trial that will include 120 participants aged 18-65 years. Participants will be randomly assigned to one of 12 treatment groups: Gel A (with or without nanoparticles, with or without light), Gel B (with or without nanoparticles, with or without light), Whiteness HP 35% (with or without light) and Whiteness Automixx 6% (with or without light). The primary outcome is tooth color change, measured using a commercially-available equipment. Secondary outcomes will include tooth sensitivity and patient satisfaction. Randomization will be computer-generated. Results: The study is expected to show differences in color change between the experimental and commercial gels. Tooth sensitivity and patient satisfaction will be evaluated to determine the overall effectiveness and safety of the treatments. Conclusions: This trial will provide information into the whitening efficacy of two experimental gels compared to two widely used commercial products.
NCT05750745
The purpose of this study is to evaluate the efficacy of the 0.454 percentage (%) weight/weight (w/w) stannous fluoride (SnF2) toothpastes for the relief of dentine hypersensitivity (DH) in China.
NCT05083052
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%.
NCT04950465
The purpose of this study is to support long-term dentinal hypersensitivity (DH) relief claims of 0.454 percent (%) stannous fluoride (SnF2) containing toothpastes in China.
NCT05309967
Tooth whitening is one of the most indicated aesthetic procedures in dentistry and there is evidence that it interferes with aspects of patients' quality of life. However, the sensitivity, associated with the post-procedure period, challenges clinicians and researchers. The use of topic desensitizing agents could be a alternative for the control of this adverse effects of bleaching agents. The objective of this randomized clinical study, therefore, is to evaluate the effect of glutaraldehyde-based desensitizing agent associated on tooth sensitivity and tooth color after bleaching with 35% hydrogen peroxide. 25 patients will be selected divided into two groups for a double-blind and split-mouth study. Among the results it is expected: that the use of glutaraldehyde desensitizing agent helps in the control of post-bleaching sensitivity, without harming the final color obtained of patients submitted to the proposed clinical protocol.
NCT03943095
This exploratory study will characterize the efficacy profile of an experimental dual active 5 percent (%) potassium nitrate/0.454% stannous fluoride dentifrice, compared to a single active 0.454% stannous fluoride desensitizing dentifrice, over an 8-week treatment period.
NCT01111474
This study aimed to evaluate the effectiveness of two treatments for dental hypersensitivity: cyanoacrylate (Super Bonder®) compared with use of low intensity laser treatment (LILT). As the cyanoacrylate is a lower cost treatment, the hypothesis in investigation is if this product is equally effective as the laser treatment.
NCT02481557
This study will assess sensitivity during a dental prophylaxis with or without the use of a potassium oxalate salt solution.
NCT02651467
This will be a single center, eight week, randomized, double blind, three treatment arm, parallel design, stratified (by mean baseline Schiff Sensitivity Score of the two selected test teeth) study in healthy participants.
NCT03434782
To investigate the effects of desensitizing agents on the dental bleaching process, testing the hypothesis that they may control dental sensitivity.
NCT02773758

NCT02770573
Aim: to investigate the clinical effectiveness over 12 weeks of three different biomaterials, nano-hydroxyapatite based, in the therapy of the dental sensitivity. Methods: The study is designed as a randomized clinical trial comparing: 1) Cavex Bite\&White ExSense, 2) Teethmate™ Desensitizer , 3) Ghimas Dentin Desensitizer. The pain experience was generated by a cold stimulus directly to a sensitive tooth surface and assessed using the Visual Analogue Scale (VAS). The response was recorded before the application of the materials (PRE-1), immediately after (POST-1), at 1-week (POST-2), 4-weeks (POST-3) and 12-week controls (POST-4).

Aim: To compare the desensitizing capacity of Vertise Flow™ (VF), a new self adhering material, in the treatment of dentine hypersensitivity (DH) in patients who are xerostomic due to radiotherapy for head and neck cancer. Methods: A total of 17 patients were selected for the study. The study was conducted as a split-mouth randomized clinical trial comparing: 1) VF 2) Universal Dentin Sealant (UDS), 3) Clearfil Protect Bond (CPB) and 4) Flor-Opal® Varnish (FOV). Basal and stimulated salivary flow was recorded for each patient according to the method described by Sreebny. The pain experience was generated by a cold stimulus directly to a sensitive tooth surface and assessed using the Visual Analogue Scale (VAS). The response was recorded before the application of the materials (PRE-1), immediately after (POST-1), at 1-week (POST-2), 4-weeks (POST-3) and 12-week controls (POST-4).
