Active clinical trials for "Dentin Sensitivity"

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).

This is a single center, randomized control. Sixty eligible subjects will be recruited into 3 study treatment groups (n=20 per group) through computerized randomization. Subjects in group 1 will be treated with 8% arginine containing paste(Colgate® Sensitive Pro-Relief™), group 2 with 5% topical fluoride varnish (Acclean) and group 3 with self-adhesive resin (Seal and protect, Dentsply). The subjects in the study will be evaluated for tactile and air-blast hypersensitivity criteria at baseline, two and four weeks.

This study aims to evaluate the effectiveness of different protocols in controlling dentin hypersensitivity in patients with teeth affected by MIH. The subjects will be randomly designated in four experimental groups, according to different treatments. Pain will be assessed with the visual analog scale (Visual Analogue Scale - VAS), after stimulation with air from the triple syringe and and an exploratory probe at the time of (initial) recruitment, immediately after treatment, after 1 week and 1 month, 3 and 6 months after treatment.

The aim of this study is through a double blind randomized clinical trial, evaluate the effectiveness of different clinical protocols in the reduction of dentin hypersensitivity. The desensitization approach (single agent or associated agents) and the long-term effectiveness (baseline, 1 week, 2 weeks, 4 weeks, 12 weeks and 24 weeks) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.

Background: Dentin hypersensitivity (DH) is defined as high sensitivity of the vital dentin when exposed to thermal, chemical or tactile stimuli. Two mechanisms are required for the occurrence of DH: 1) the dentin must be exposed and 2) the dentinal tubules must be open and connected to the pulp. Molar-incisor hypomineralization (MIH) is a qualitative abnormality of a genetic origin that affects tooth enamel and, in most cases, is accompanied by DH. The control of tooth sensitivity is fundamental to the successful treatment of MIH. Objective: The aim of the proposed randomized, controlled, clinical trial is to evaluate the effectiveness of different protocols for the control of DH in patients with teeth affected by MIH. Methods: One hundred forty patients who meet the inclusion criteria will be allocated to four groups. Group 1 will be the control group (placebo). In Group 2, sensitive teeth will be sealed with Permaseal (Ultradent). In Group 3, sensitive teeth will receive low-level laser (LLL) (AsGaAl) at a wavelength of 780 nm (Laser XT Therapy, DMC, São Carlos, SP, Brazil). In Group 4, sensitive teeth will be treated with both LLL and Permaseal (Ultradent). DH will be evaluated 15 min after the application of the treatments and the patients will be reevaluated one week, one month, three months and six months after the treatments. Discussion: This study will enable the determination of differences in the effectiveness of the proposed treatments as well as differences among the evaluation times for each proposed treatment.

The aim of this study is to evaluate the Desensitizing efficacy of polymeric nano calcium fluoride containing varnish and its implementation into clinical practice.

Introduction: Dentin hypersensitivity (DH) could be defined as a brief and sharp pain in response to thermical, chemical, tactile and osmotic stimuli, which cannot be attributed to any dental condition or pathology. Multiple therapies for the treatment of DH have been studied, including equivocal evidence about the efficacy of potassium nitrate salts and recent investigations a promising new 8% Arginin dentifrice. Aim: The aim of this study is to compare the clinical effectiveness of 8% arginine/1450ppm sodium monofluorophosphate (D1) and 5% potassium nitrate/2500ppm sodium fluoride (D2) dentifrices in the treatment of dentin hypersensitivity. Methods: Parallel-design, double-masked, randomized controlled clinical trial. Fifty healthy volunteers aged 18 to 70 years who attend at the Faculty of Dentistry , University of Chile, with DH and a visual analog scale (VAS) score ≥4 at least in two anterior and/or premolar teeth, will be selected and randomized into two treatment groups: T1 (n=25): 8% arginine/1450 ppm sodium monofluorophosphate dentifrice (D1); and T2 (n=25): 5% potassium nitrate/2500 ppm sodium fluoride dentifrice (D2). Environmental, dietary and oral hygiene habits will be recorded in a clinical chart, while O´Leary plaque index and dentin hypersensitivity (DH) measurements will be clinically assessed, at baseline, 4 and 8 weeks. DH will be evaluated through the mean VAS value in response to evaporative and thermal stimuli at baseline, 4 and 8 week follow-up. The data will be analysed through Stata® V11 program.

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.

Will the use of Bio-smart Light Cured Protective Shield with bioactive S-PRG filler or the use of Sodium Fluoride with Xylitol-coated Calcium and Phosphate (CXP™) Varnish be able to reduce the teeth hypersensitivity similar to Sodium Fluoride Varnish?

The aim of the study to compare the clinical effectiveness of Shield Force Plus (SFP) versus sodium fluoride varnish in the management of hypersensitivity of cervical dentin in adult patients for 8weeks.
