A proof of principle single-centre, randomized-controlled, examiner-blind, two treatment group study to investigate the efficacy of an experimental 15% w/w dissolvable strip in relieving dentine hypersensitivity (DH) after a single application and up to 4 hours after application compared to no treatment.
This will be a single-centre, randomized-controlled, examiner-blind, two treatment group (test and no treatment), parallel design, stratified (by maximum baseline Schiff sensitivity score of the two selected test teeth) study, in healthy participants with at least two sensitive teeth that meet all the criteria at the screening and the baseline pre-treatment visit. DH will be assessed at baseline (pre-treatment), and 10mins, 2 & 4 hours post-treatment.
Allocation: Randomized, Intervention Model: Single Group Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Treatment

The purpose of this exploratory study is to compare the treatment effect on dentinal hypersensitivity of a tubule occluding dentifrice as measured by Schiff and Tactile sensitivity. This p...
This study will investigate the effectiveness of nanohydroxyapatite (nano-HAP)-containing toothpastes and cream to relieve dentin hypersensitivity, comparing it with those of a commercial ...
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 den...
To investigate the effects of desensitizing agents on the dental bleaching process, testing the hypothesis that they may prevent dental sensitivity.
The aim of the proposed study is to assess the clinical effect of photodynamic therapy (PDT)using LED on dentin with carious lesions in permenent teeth. Patients with molars exhibiting dee...
Palatoradicular grooves (PRGs), morphologic defects that are found most frequently in maxillary anterior teeth, are predisposing factors for periodontal disease. This case report describes the success...
Comparative analysis of the coronal microleakage of a self-etching priming dentin adhesive with the use of antioxidant (Sodium Ascorbate (SA) and herbal quercetin) after Sodium hypochloride (NaOCl) an...
The aim of this study was to assess the effects of intracanal irrigation with sodium hypochlorite (NaOCl) and ethylenediaminetetracetic acid (EDTA) prior to calcium hydroxide medication on the compres...
A subset of potassium channels is regulated primarily by changes in the cytoplasmic concentration of ions, including calcium, sodium, chloride, and protons. The eight members of this subfamily were or...
The nociceptive noxious heat-activated receptor - TRPV1, conducts calcium and sodium, thus producing a depolarizing receptor potential, leading to activation of nociceptive neurons. TRPV1-mediated cal...
Adherent debris produced when cutting the enamel or dentin in cavity preparation. It is about 1 micron thick and its composition reflects the underlying dentin, although different quantities and qualities of smear layer can be produced by the various instrumentation techniques. Its function is presumed to be protective, as it lowers dentin permeability. However, it masks the underlying dentin and interferes with attempts to bond dental material to the dentin.
An serine-threonine protein kinase that requires the presence of physiological concentrations of CALCIUM and membrane PHOSPHOLIPIDS. The additional presence of DIACYLGLYCEROLS markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by PHORBOL ESTERS and it is believed that protein kinase C is the receptor protein of tumor-promoting phorbol esters.
An electrogenic ion exchange protein that maintains a steady level of calcium by removing an amount of calcium equal to that which enters the cells. It is widely distributed in most excitable membranes, including the brain and heart.
An apparently hereditary disorder of dentin formation, marked by a normal appearance of coronal dentin associated with pulpal obliteration, faulty root formation, and a tendency for peripheral lesions without obvious cause. (From Dorland, 27th ed)
Dentistry is the study, management and treatment of diseases and conditions affecting the mouth, jaw, teeth and their supporting tissues (Oxford Medical Dictionary) The work of a dentist ranges from regular patient check-up to orthodontics and surgery....
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
