Active clinical trials for "Dentin Sensitivity"

This is a three year single site clinical evaluation of a FDA approved (510(k):K100062) lesion penetrating resin used to infiltrate and hamper progression of proximal carious lesions. The purpose of this study is to compare lesion progression infiltrated with (Icon, Hamburg, Germany) to a similar sized lesion in the same patient treated with a placebo. The study is designed as a randomized, controlled, prospective clinical trial with a three year follow-up evaluation period. The clinical site will enroll 150 subjects (in the age range of 19 years or older) with 2 study lesions. The patients will be evaluated at six time points over a period of 3 years. Lesion status and caries risk will be monitored at 6-month intervals, while radiographic evaluation will be conducted at 12-month intervals at 1-, 2- and 3-year recall visits.

This study will investigate the efficacy of an experimental dentifrice containing 0.454% weight/weight (w/w) stannous fluoride in relieving dentine hypersensitivity (DH) after twice daily brushing, over a 2 week treatment period compared with a standard fluoride dentifrice.

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.

A study to compare the efficacy of a test dentifrice against a control dentifrice in reducing dentinal hypersensitivity over a two week treatment period.

This randomized, double-blind clinical trial aimed to evaluate the effect of an experimental gel containing 10% jambu extract (Acmella Oleracea) in reducing postoperative tooth sensitivity caused by bleaching with 35% hydrogen peroxide. The volunteers of this study were randomized into two different groups - GE (A. Oleracea extract at 10%) and GP (placebo). The dental elements of the GE 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 GP group also received the application of a placebo gel (without active ingredient), 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).

This study will compare the safety and effectiveness of a potassium oxalate desensitizer or negative control on dentinal hypersensitivity.

This study is for people with sensitive teeth and involves going to the dentist for 4 visits over 6 weeks. At each visit the dentist will look at the mouth, teeth, tongue and gums of participants, and check for sensitive teeth. During the first 2 weeks, participants will brush their teeth 2 times a day with the fluoride toothpaste provided. Then, if they qualify to continue in the study, participants will be assigned to one of two treatment groups for the last 4 weeks. Both groups will use assigned toothpaste currently sold on the market. Both groups will each have an investigative mouth rinse to use as well. Participants will have an equal chance of being assigned to any one of the three groups. For the next 4 weeks, participants will use their assigned products according to the directions provided. At Visit 1, participants will be supervised while they brush their teeth to ensure they understand the directions. They will also have supervised use of the products at Visit 2. Results will be analyzed to assess whether the mouthwashes help to reduce tooth sensitivity during the study.

The study is intended to verify through clinical measurement that the NUPRO Sensodyne Prophylaxis Paste with Novamin provides immediate sensitivity relief as well as extended relief up to 28 days.

Tooth hypersensitivity due to dental erosion is one of the most common problem related to swimming in improper pH chlorinated pools. Because the teeth are exposed to acidic water for a long time, which cause the loss of dental hard tissue. Tooth hypersensitivity can lead to a negative effect on daily life such as dietary selection, maintaining optimal dental hygiene and beauty aspects. It has been found that using mouthguard while swimming can prevent the teeth directly contact to chlorinated water, so it can protect tooth structure and decrease tooth hypersensitivity. Moreover, using mouthguard with viscous products can seal the gaps between mouthguard and teeth which can help to protect tooth structure and decrease dental hypersensitivity more effectively. At present, there are many desensitizing products such as toothpaste, mouthwash and chewing gum. Desensitizing toothpaste is the most common over-the-counter (OTC) materials in desensitizing. Many research has endorsed the properties of desensitizing toothpaste that can reduce tooth tissue loss and helps to reduce tooth hypersensitivity effectively. So it can be hypothesize that when use the combination of mouthguard with desensitizing toothpaste, it might have synergistic effect on reducing tooth hypersensitivity in swimmers.

Objectives: This study will determine the clinical efficacy of bleaching agent 37% carbamide peroxide compared to 35% hydrogen peroxide on the change of color scores in anterior superior teeth, in-office bleaching technique after 7, 14 and 37 days; and the Risk to the tooth sensitivity before, during and 24 hours after the procedure. Materials and Methods: Fifty patients will be selected for this single-blind, parallel, randomized-controlled clinical trial. The whitening treatment with 37% carbamide peroxide or 35% hydrogen peroxide (control) will be carried out in a single application of 45 minutes for two sessions with a 7-day interval. The sensitivity level will be assessed before, during and 24 hours after the procedure using verbal and analogic visual analogue (VAS) scales. Color alteration will be assessed by a bleach guide scale 7 days after each session and 30 days after the last session. Relative risk to sensitivity will be calculated and adjusted by session; while comparison of overall risk will performed by McNemar's test. Data on the sensitivity level for both scales will be subjected to the Mann-Whitney tests (α = 0.05). The color change will be measured with a spectrophotometer using the CIE L * a * b * and the L*, a * and b * parameter delta data, and ΔE and Δ00, will be individually subjected to two-way repeated measures ANOVA test to compare the two bleaching techniques at each evaluation time (α = 0.05).
