Objective: Evaluate the efficacy of 0.8% arginine, potassium nitrate and sodium fluoride mouthwashes on dentine hypersensitivity reduction. Methods: Six week randomized, double blinded, two cell, parallel single centre clinical study in the Dominican Republic; subjects were randomized into three treatment groups: mouthwash containing 0.8% argini...

Objective: The objective of this eight week, single-center, two-cell, double-blind, and randomized clinical study was to evaluate the dentin hypersensitivity reduction efficacy of a mouthwash using Pro-Argin™ Mouthwash Technology containing 0.8% arginine, PVM/MA copolymer, pyrophosphates, and 0.05% sodium fluoride in an alcohol-free base ("Arginin...

Objective: The purpose of this study was to evaluate in vitro the anti-erosion efficacy of an alcohol-free mouthwash based on a Zinc/co-polymer/Fluoride system, against negative and no-treatment (water) controls. Methods: Enamel substrates (N = 8 per cell) were prepared by embedding bovine incisors in methacrylate-based resin and polishing with 6...

With the advent of sophisticated microscopy techniques, and associated software and hardware, the ability to study the effect of antimicrobials on biofilms in detail is continually evolving. Objectives: The aim of this work was to develop and/or refine a model-system to study oral multi-species biofilms and examine their 3-dimensional architecture...

Mouthwashes have been used for decades as antimicrobial adjuncts in oral care regimens. While the antibacterial efficacy of cetylpyridinium chloride (CPC) is well known, formula differences affect the overall mouthwash efficacy. Objective: The objective of this study was to optimize a CPC-containing mouthwash formula based on performance in short-...

A number of existing studies have examined the antibacterial efficacy of mouthwashes. Of particular interest is the ability of a mouthwash to kill bacteria during the relatively short time period for which mouthwashes are indicated for use, approximately 30s. Objective: The objective of this study was to examine the ability of four Cetylpyridium Ch...

Objectives: The objective of this 6-Month, single-center, parallel-group, two-cell, double-blind, and randomized clinical study was to evaluate the clinical efficacy of a Mouthwash containing 0.075% Cetylpyridinium Chloride (Test group) as compared to a Placebo Control Mouthwash (Control group) in controlling established dental plaque and gingiviti...

Objective: Demonstrate occlusion efficacy of Colgate Sensitive Pro-Relief Desensitizing Paste via hydraulic conductance. Methods: The Hydraulic Conductance test measures the change in dentin permeability (fluid flow) upon application of a product with occlusion properties. Experiments were conducted using a flow sensor - Flodec - under simulated...
