Filter by:The aim of this randomized, double-blind, split-mouth clinical trial is to evaluate and compare the desensitizing efficacies of the resin-modified glass ionomer cement ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional glass ionomer cement Vidrion R (SS White, Gloucester, UK) at 2-year follow-up.
An 8 week clinical study to evaluate the ability of an experimental dentifrice containing calcium sodium phosphosilicate and sodium fluoride to provide relief from dentine hypersensitivity compared to a marketed dentifrice containing calcium sodium phosphosilicate and sodium monofluorophosphate.
The aim of this project is to evaluate in vitro and in vivo the effect of dental bleaching agents, carbamide peroxide 16% (T1) and hydrogen peroxide 35% (T2) together with desensitizers/remineralizer agents, Sensodyne® dentifrice (D1); experimental dentifrice with 7,5% of Biosilicate micro-particles (D2); Odontis RX® dentifrice (D3); Sorriso® dentifrice (D4); Biosilicate micro-particles paste, 1:1 (D5), Desensebilize Nano P (D6), bioglass type 45S5 paste, 1:1 (D7); GC= distilled water, in the experimental groups: T1/D1; T1/D2; T1/D3; T1/D4; T1/D5; T1/D6; T1/D7; T1/GC e T2/D1; T2/D2; T2/D3; T2/D4; T2/D5; T2/D6; T2/D7; T2/GC. In the in vitro study, microhardness and roughness measurements, and images using scanning electron microscopy (SEM) will be made on samples of bovine dental enamel and dentin (4x4x3mm; n=10 per group) before and after the treatment with the bleaching gels (T1= 14 days/ 04 hours/day; T2=single session) and the desensitizers/remineralizer agents. In the clinical study, the volunteers (n=10 per group) will be evaluated regarding dentin hypersensitivity (DH), using visual analogue scale, before the beginning of the treatments (T1 and T2) and during the next 14 days (1º, 3º, 7º, 10 º e 14º days) in which the desensitizers/remineralizer agents (there´s no control group in the clinical experiments) will be applying. Data will be analysed intra and inter-group, statistically.
This study will compare the safety and effectiveness of a potassium oxalate desensitizer on adjacent teeth with dentinal hypersensitivity.
The aim of this study is to investigate the longitudinal efficacy of a potassium nitrate mouthwash formulation when used as an adjunct to brushing with a standard fluoride dentifrice for the relief of dentinal hypersensitivity (DH) compared to brushing with a standard fluoride dentifrice alone. This will be a single centre, eight week, randomised, examiner blind, two treatment arm, parallel design, stratified (by maximum baseline Schiff Sensitivity Score of the two selected test teeth) study in participants with at least two sensitive teeth that meet all the criteria at the Screening and Baseline visit. Participants will be assessed at Baseline, and at four and eight weeks to monitor clinical efficacy and safety.
This study will compare the safety and effectiveness of normal oral hygiene with two different marketed dentifrices, on longer term dentinal hypersensitivity response following use of potassium oxalate desensitizers.
This study will compare the safety and effectiveness of two water-based potassium oxalate desensitizers on existing dentinal hypersensitivity.
This study will compare the safety and effectiveness of a potassium oxalate desensitizer or negative control on dentinal hypersensitivity.
This study will compare the safety and effectiveness of two water-based potassium oxalate desensitizers on existing dentinal hypersensitivity.
Aim: To evaluate the effectiveness of a desensitizing gel for topical and home use in the treatment of dentin hypersensitivity (DH) through a randomized clinical trial, double-blind, with three parallel treatment. Methods: 126 subjects were divided into three groups: placebo gel (PG), test gel (TG) (5% sodium fluoride, potassium oxalate 5%, strontium chloride 10%) and sodium fluoride gel (2% FG ). The measurement of DH was performed by a single examiner blinded by the visual analog scale (VAS) after tactile, thermal and osmotic stimuli in the Baseline, 7, 15 and 30 days.
