Active clinical trials for "Dentin Sensitivity"

There is a lack of long-term clinical studies comparing different restorative materials; most of the available studies have only looked at class I cavities or examined post-operative sensitivity in non-caries cervical lesions. The purpose of this study is to measure postoperative sensitivity in clinical settings at 3-month intervals for class 1 and 2 direct posterior restoration

The aesthetics of dental elements generates great psychological and social impacts, both in the deciduous and permanent dentition. One of the techniques widely used to visually improve the appearance of teeth is bleaching. Bleaching can be performed both at home and in a dental office. In office whitening, the technique used consists of applying the whitening gel to the dental surfaces in concentrations ranging from 25% to 50% of hydrogen peroxide. However, recent studies show that low and medium concentration bleaching agents based on hydrogen peroxide have been effective and present a lower risk of sensitivity to the patient. In view of the above, this study aims to carry out a controlled and randomized clinical trial to compare the effectiveness of dental bleaching in deciduous teeth with hydrogen peroxide at concentrations of 35% and 6%. For this, 38 patients aged 03 to 06 years will be selected, allocated in 2 groups (G1 - Hydrogen Peroxide 35%, n=19 and G2- Hydrogen Peroxide 6%, n=19). Bleaching will be carried out in up to three sessions, with an interval of 7 days between them and the evaluation of color and tooth sensitivity will be carried out 48 hours after each bleaching session. The color assessment will be measured using a digital spectrometer and tooth sensitivity using the Pain Level Scale (Wong-Baker Faces®). Descriptive statistical analysis will be carried out, containing the mean and standard deviation in the calculation and normality and homogeneity tests will be carried out, for subsequent adequate statistical analysis. As a result, it is expected that there is no significant difference between the groups in terms of color variation and that the low-concentration bleaching group has the lowest sensitivity index.

This trial is test the dentin hypersenstivity using Giomer based Varnish versus Bioactive glass air polishing system in patients with non-cervical lesions.

This randomized, double-blind clinical trial aimed to evaluate the effect of an experimental gel containing copaiba oil resin in reducing postoperative tooth sensitivity caused by bleaching with 35% hydrogen peroxide. The volunteers of this study were randomized into 3 different groups - GC (placebo); GN (potassium nitrate and sodium fluoride); GCO (copaiba oil resin). The dental elements of the GCO received application of the experimental desensitizing gel on the buccal surfaces of the central incisors, lateral incisors, canines and upper and lower premolars, with a rubber cup in an active way, for 10 minutes. The GC and GN groups also received the application of a placebo gel and a nitrate potassium and sodiun fluoride gel, respectively, under the same conditions described for the experimental gel. Subsequently, all groups underwent in-office bleaching treatment with 35% hydrogen peroxide. Post-bleaching sensitivity was collected through a form composed of the visual analogue scale (VAS). Color measurement was performed at two times: baseline (Ti) and one week after the 3rd bleaching session (Tf).

Comparison of the clinical effectiveness of self etch adhesive and fluoride varnish in reducing dentin hypersensitivity in patients with gingival recession. A Randomized Clinical Trial ABSTRACT Objective: To compare the clinical effectiveness of self etch adhesive and fluoride varnish in reducing dentin hypersensitivity in patients with gingival recession Study Design: Randomized Clinical Trial Place of Study: Department of Operative Dentistry and Endodontics, Peshawar Dental College, Warsak Road. Methodology: 142 diagnosed cases of Dentin hypersensitivity from outpatient department of nephrology, Prime Hospital Peshawar will be referred to operative department, Peshawar dental college for Comparison of the clinical effectiveness of self etch adhesive and fluoride varnish in reducing dentin hypersensitivity in patients with gingival recession. Results: Conclusion:

Forty-four patients with dentin sensibility after non-surgical scaling and root planning (SRP) will be randomly included in 2 groups: Experimental Group: SRP+ Photobiomodulation (PBM) (660nm, 100W, area 0,5cm2, 200w/cm2, 30 seconds, 3 J, 6J/cm2. The primary outcome of the study will be the assessment of dentinal sensitivity after 7 days of RAR measured with the visual analog scale (VAS). The cutoff of VAS is 3. Also, it will be assessed the impact of oral health on the participant's quality of life, with the OHIP-14 questionnaire. The use of analgesics (paracetamol) will be prescribed as needed and the amount of medication will be calculated. These outcomes will be evaluated after 7 days and 1 month of application

A dental gel intended to relieve pain related to dentin hyper sensitivity is commercialized in several countries worlwide since May 2017. Its efficacy and tolerance has already been proven in dentin hyper sensitivity. In this new study, we assess the efficacy and tolerance of this tested product in a specific external agression, the teeth whitening.

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.

Dentin hypersensitivity is one of the most commonly occurring clinical dental conditions which is characterized by short and sharp pain which arises from exposed dentin in response to external stimuli, which typically are thermal, evaporative, tactile, osmotic or chemical. Hypersensitive dentin is mostly found in buccal tooth areas, in which enamel is missing because of abrasion, attrition, or erosion. The most generally accepted theory regarding the mechanism of dentin hypersensitivity is the hydrodynamic theory. It proposes that a pain-provoking stimulus increases the flow of the dentinal tubular fluid and consequently, stimulates the nerves around the odontoblasts, leading to dentin hypersensitivity.

The goal of this clinical trial is to evaluate the effect of 3M™ Clinpro™ Fluoride Aqueous Solution (experimental) on Dentin Hypersensitivity (DHS) in comparison to 3M™ Vanish™ (commercialized, control] in patients who have DHS. Participants will be asked to complete the following activities: Undergo a pre-treatment washout period for 3- to 6-weeks (± 4 days) post-enrollment. During this time, the Subject is to only use the provided oral hygiene products. Hypersensitivity will be assessed prior to (baseline) and immediately after sample application. Subject will be asked to come to the facility for hypersensitivity assessments at 24 hours, 7 days, and 30 days after the treatment visit. Researchers will compare 3M™ Clinpro™ Fluoride Aqueous Solution to 3M™ Vanish™ to evaluate if the effect of Clinpro™ on DHS treatment is non-inferior to Vanish™.
