Effect of artificial saliva on permeability of dentin treated with phosphate containing desensitizer measured by digital flow meter.

The aim of this study was to investigate the effects of artificial saliva on permeability measured using a highly sensitive digital flow meter of dentin discs treated with a phosphate containing desensitizer compound (Teethmate desensitizer; TD). Four random groups (n=10) were treated either with TD or distilled water (DW), then stored in artificial saliva (AS) or DW for 1 day, 1 week and 1 month. Flow rates under 2 kPa pressure were calculated as percentage reduction (PR%) from the baseline.

Novel treatment of in-office tooth bleaching sensitivity: A randomized, placebo-controlled clinical study.

Objectives: Aim of this clinical trial was to investigate the effect of a calcium phosphate based desensitizer paste applied prior to in-office tooth whitening on bleaching sensitivity (BS).

Methods: This crossover study was designed as randomized double-blinded, placebo-controlled trial. The desensitizer paste Teethmate AP (TAP) contains tetracalcium phosphate and dicalcium phosphate anhydrous in glycerol and polyethylene glycol, whereas placebo (PLA) is a calcium phosphate free analog.

Effect of two desensitizing agents on dentin permeability in vitro.

Objective: The aim of this in vitro study was to investigate the effect of two desensitizing agents and water on hydraulic conductance in human dentin.

Material And Methods: GLUMA Desensitizer PowerGel (GLU) contains glutaraldehyde (GA) and 2-hydroxyethyl methacrylate (HEMA), and Teethmate Desensitizer (TD) is a powder comprising tetracalcium phosphate (TTCP) and dicalcium phosphate anhydrous (DCPA) that is mixed with water. Deionized water was used as a negative control (CTR).

Discoloration of various CAD/CAM blocks after immersion in coffee.

Objectives: This study evaluated color differences (Δs) and translucency parameter changes (Δs) of various computer-aided design/computer-aided manufacturing (CAD/CAM) blocks after immersion in coffee.

Materials And Methods: Eight CAD/CAM blocks and four restorative composite resins were evaluated. The CIE values of 2.

Effect of a Calcium Phosphate Desensitizer on Pre- and Postcementation Sensitivity of Teeth Prepared for Full-Coverage Restorations: A Randomized, Placebo-Controlled Clinical Study.

Purpose: The aim of this study was to investigate the effect of Teethmate Desensitizer (TD), an aqueous slurry of calcium phosphates, on the pre- and postcementation sensitivity of contralateral premolars prepared for full-coverage restorations.

Materials And Methods: In this clinical study, using a split-mouth design, 20 patients were allocated and two contralateral vital premolars per patient were randomly assigned to treatment with TD and placebo (PLA; distilled water). One day after preparation and temporization, sensitivity (PRE) upon air blast (AB) and probe scratch (PS) was determined using a 10-cm-long visual analog scale (VAS).
