NCT ID: NCT06394557 Active, not recruiting - Tooth Sensitivity Clinical Trials

Evaluation of In-office Bleaching-induced Sensitivity With 2 or 7 Days Interval Between Sessions

Start date: August 14, 2023
Phase: N/A
Study type: Interventional

Clinical randomized single-blind trial, used to measure the level of tooth sensitivity (TS) after in-office dental bleaching sessions, on volunteers using a modified visual analog scale (VAS). We selected for this study, 47 patients with color 2M2 or darker (Using 0M1 - 5M3 Vita bleaching shade guide). We performed two bleaching sessions with an acidic 35% hydrogen peroxide gel with either a 1-week or 2-day interval. We recorded the TS up to 48 h with a VAS scale and the color at baseline and 30 days after bleaching with a value-oriented shade guide and a spectrophotometer. The risk and intensity of TS and the color change were compared between the two groups.

NCT ID: NCT06288776 Completed - Tooth Sensitivity Clinical Trials

Efficacy of Azadirachta Indica Based Herbal Mouthwash in Treating the Tooth Hypersensitivity

Start date: February 1, 2023
Phase: N/A
Study type: Interventional

Type of study: Single-blinded clinical trial to evaluate the effectiveness of Azadirachta indica based Herbal mouthwash to treat the tooth sensitivity in patients. Participants aged 20 years and above having Gingival Index score 3 will be included in the study. Their tooth sensitivity will be checked initially and then they will be given Herbal based mouthwash for 3 months. Again, their tooth sensitivity shall be checked after 3 months.

NCT ID: NCT05865275 Completed - Tooth Sensitivity Clinical Trials

Diode Low-power Laser Before In-office Bleaching

Start date: November 9, 2021
Phase: N/A
Study type: Interventional

Background: The aim of study was to investigate the effectiveness of low-level laser therapy (LLLT) use before in-office bleaching to prevent risk and intensity of tooth sensitivity. Methods: thirty patients were selected for this clinical trial. Before bleaching procedures with 38 % hydrogen peroxide, the participants were randomly divided into two groups of 15 subjects. Test group: the patients teeth received a preliminary LLLT procedure by an 810 nm diode laser with 0.5 Watt for 30 s for an energy density of 15 J/cm2 and a group placebo: the patients received the same preliminary LLLT but with the device switch off. All patients were instructed to report their cold sensitivity experiences immediately, 1 h, 24 h, and 48 h after the end of bleaching by a visual analog scale score between 0-10.

NCT ID: NCT05835453 Recruiting - Gingivitis Clinical Trials

At-home Bleaching Using Clear Aligners

Start date: April 14, 2023
Phase: N/A
Study type: Interventional

The aim of the present project is to clinically evaluate the bleaching effectiveness, tooth sensitivity, gingival irritation and patient´s satisfaction during a at-home bleaching with 10% carbamide peroxide using a conventional bleaching tray or a clear aligner.

NCT ID: NCT05635253 Completed - Tooth Discoloration Clinical Trials

Influence of Polishing After Bleaching on Color Change and Enamel Morphology

Start date: January 10, 2022
Phase: N/A
Study type: Interventional

This trial evaluated the influence of polishing on enamel color change after in-office bleaching treatment. It also evaluated the influence of polishing on tooth morphology and sensitivity.

NCT ID: NCT05483062 Completed - Tooth Sensitivity Clinical Trials

Effectiveness of Toothpaste Containing the Active Ingredient of Galla Chinensis Extract on Treating Dentin Hypersensitivity

Start date: May 20, 2021
Phase: N/A
Study type: Interventional

This clinical trial was conducted to compare the desensitizing effect of toothpaste containing the active ingredient of an extract of Galla chinensis and toothpaste containing fluoride in patients with dentin hypersensitivity.

NCT ID: NCT04855279 Completed - Tooth Bleaching Clinical Trials

Prevention of Bleaching Induced Sensitivity

Start date: January 7, 2019
Phase: N/A
Study type: Interventional

This study aims to evaluate the use of different desensitizing agents before in-office bleaching. A total of 64 volunteers were randomly divided into four groups. Before undergoing in-office bleaching with 38% hydrogen peroxide gel (three applications of 15 minutes each, one session), clinicians applied a placebo gel (control group), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), neutral sodium fluoride gel (NSF), or nano-hydroxyapatite solution (n-HAP) on all buccal surfaces of teeth. The gel was left undisturbed for 4 minutes. Patients recorded their tooth sensitivities on the VAS scale. Kruskal-Wallis test followed by Mann-Whitney U test were used to compare changes in tooth color and intensity of tooth sensitivity between groups.

NCT ID: NCT03403088 Completed - Tooth Sensitivity Clinical Trials

Non-carious Cervical Lesions and Treatments

NCCL
Start date: August 1, 2017
Phase: N/A
Study type: Interventional

This study will compare clinically the efficacy, time to action and duration of different treatments for patients with non-carious cervical lesions (NCCLs) that caused dentin hypersensitivity (DH).

NCT ID: NCT03323372 Completed - Tooth Sensitivity Clinical Trials

Different Concentrations of Potassium Nitrate in In-office Tooth Bleaching Sensitivity

Start date: December 21, 2016
Phase: Phase 2
Study type: Interventional

The aim of this randomized, double-blind controlled clinical study was to evaluate the absolute risk and intensity of sensitivity to dental bleaching in adults on the application of two different gels based on potassium nitrate and sodium fluoride from a prospective randomized clinical study.

NCT ID: NCT03153657 Completed - Tooth Sensitivity Clinical Trials

Piroxicam-beta-Cyclodextrin on Tooth Sensitivity Caused by In-office Bleaching

Start date: December 13, 2016
Phase: Phase 3
Study type: Interventional

Objectives: This study aims to evaluate the effectiveness of preemptive administration of non-steroidal anti-inflammatory Piroxicam-beta-Cyclodextrin on risk and level of tooth sensitivity caused by in-office bleaching procedures using 35% hydrogen peroxide. Fifty patients will be selected for this triple-blind, randomized, cross-over, placebo-controlled clinical trial. Piroxicam-beta-Cyclodextrin (200 mg) or placebo will be administrated in a single-dose thirty minutes prior to bleaching procedure. The whitening treatment with 35% hydrogen peroxide will be carried out in two sessions with a 7-day interval. Tooth sensitivity will be assessed Immediately before bleaching agent removal and up to 24 hours after each session the procedure using analog visual and verbal scales. Color alteration will be assessed by a bleach guide scale 7 days after each session. Relative risk to sensitivity will be calculated and adjusted by session; while comparison of overall risk will performed by Fisher's exact test. Data on the sensitivity level for both scales and color shade will be subjected to the Mann-Whitney and Friedman tests, respectively (α = 0.05).
