Objective: The purpose of this study was to evaluate the effects of application of three over the counter whitening toothpastes (Colgate Optic White, Aquafresh Ultimate White and Crest 3D White) on the color stability of different esthetic restorative materials (Resin composite/Filtek Z250 XT, resin modified glass ionomer/GC Fuji II LC, and glass ionomer/Ketac Molar Quick Aplicapweek) commonly ...

AIM To compare the safety and efficacy of two manual toothbrushes, Oral-B Exceed and Asian Colgate 360 masculine, in removing plaque. METHODS AND MATERIALS The study used an examiner-blind, two-treatment, randomized, four-period (visits) crossover design. At the first visit, subjects received a baseline plaque examination; plaque was scored using the Rustogi et al. Modified Navy Plaque Index ...

PURPOSE To evaluate the extrinsic stain profiles of two experimental stannous-containing dentifrice prototypes compared to two marketed control dentifrices. METHODS This was a 5-week, randomized, four-treatment, parallel group, double-blind clinical trial of healthy adults. Following a baseline Lobene Stain Index evaluation, subjects received a prophylaxis limited to the 12 anterior teeth to ...

Aim: This study determined whether prior brushing with desensitizing toothpastes (Sensodyne Rapid Relief and Colgate Pro-Relief) affected the shear bond strengths of composite to dentine surfaces after appropriate use of two different dentine bonding agents (SingleBond and PQ-1). Materials and Methods: Sixty caries free molar teeth were cleaned, disinfected and embedded in individual cylinders ...

AIM To compare and evaluate the remineralizing potential of four commercially available products namely SHY-NM, GC Tooth Mousse Plus, ReminPro and Colgate strong teeth on demineralized human teeth. MATERIALS AND METHODS The study included 50 extracted premolars having 3 × 3 mm window prepared on the middle third of the tooth, which was then subjected to demineralization for 48 hours at 37°C. ...

One of the major innovations in dental home care therapy was the introduction of fluorides in the 1950s for the management of dental caries. Since that time, fluoride has not only been incorporated into dentifrices, but also into a variety of delivery systems. It was not until the 1990s that the next significant advance in patient home care occurred with the introduction by the Colgate-Palmoliv...

The association between a toothbrush and a dentifrice is the most used denture cleaning method. The purpose of this study was to evaluate the abrasiveness of specific and non-specific denture cleaning dentifrices on different heat-polymerized acrylic resins. Sixteen specimens (90 x 30 x 3 mm) of each acrylic resin (QC-20, Lucitone 550, Clássico, Vipi-Cril) were prepared and randomly assigned to...

The aim of this in vitro study was to evaluate the effect of different mouthwashes on superficial roughness and Knoop hardness of two resin composites. Eighty specimens (6 mm Ø and 2 mm height) were prepared and divided into eight experimental groups (n = 10) according to the resin composites (4 Seasons and Esthet X), and storage solutions (G1 - Distilled water; G2 - Colgate Plax Overnight; G3 ...
