Trial of Nano-hydroxyapatite-Containing Toothpastes for Relief of Dentin Hypersensitivity

Dentin Sensitivity

Subjects will be enrolled into 3 balanced groups each using a different strength toothpaste. Dental hypersensitivity (DHS) will be assessed at study start, midway and study end.

Effectiveness of Bioactiveglass Air Abrasion Versus Fluoride Varnish in Management of Dentin Hypersensitivity...

Hypersensitivity DentinTooth Hypersensitivity

Will the use of Bioactive glass with air abrasion technology (Sylc) compared to Fluoride Varnish (Biflourid 10) affects the degree of pain in patients complaining from hypersensitivity due to non-carious lesions?

Study to Investigate the Efficacy of an Occluding Dentifrice in Providing Relief From Dentine Hypersensitivity...

Dentin Sensitivity

This will be a single centre, two week, randomised, examiner blind, two treatment arm, parallel design, stratified (by maximum baseline Schiff sensitivity score of the two selected test teeth), controlled study, in participant with at least two sensitive teeth that meet the study criteria at the Screening and Baseline visits. The study will be conducted in participants in good general health, with pre-existing self-reported and clinically diagnosed tooth sensitivity at screening.

Diode Low-power Laser Before In-office Bleaching

Tooth Sensitivity

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.

Prevention of Bleaching Induced Sensitivity

Tooth BleachingTooth Sensitivity

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.

Effect of an Anti-inflammatory on Tooth Sensitivity Caused by Bleaching

Color Changes During Tooth Formation

Perhaps the use of a more selective anti-inflammatory drug, capable of inhibiting enzyme specific for pain may be more effective in preventing the tooth sensitivity caused by the inflammatory response produced by in-office bleaching. To the extent of the authors´ knowledge, no study has so far addressed the use of a selective anti-inflammatory drug specific for pain enzyme on tooth sensitivity, being this the aim of the present investigation.

Hypersensitivity and Color Changes of Bleached Teeth Using Different Remineralizing Agents

Tooth Hypersensitivity

The aim of this in vivo study is to evaluate the post-bleaching enamel hypersensitivity and the possible color changes following the application of arginine and nano-hydroxyapatite remineralizing solutions after enamel bleaching using an in-office chemical bleaching agent. A commercial Fluoride remineralizing and desensitizing agent will be used as the control group. Following bleaching of the anterior teeth and then the application of the different tested remineralizing agents; the patients will be assessed for post-bleaching hypersensitivity using the visual analogue scale (VAS) to describe the severity of the hypersensitivity from mild to moderate to severe. On the other hand, the baseline shade and post-bleaching color changes will be evaluated using a shade guide. The data will be collected and tabulated then the statistical analysis will be performed. The null hypothesis is that the different tested remineralizing agents will have a similar effect on the post-bleaching teeth hypersensitivity & the color changes of the bleached teeth.

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

Tooth SensitivityToothache

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).
