The objective of this study is the development an in vitro cell culture model pigmented gingival keratinocytes to provide a unique tool assess oral care products such as toothpaste and evaluate whether cells might be less susceptible than unpigmented cytotoxicity by any toothpaste. Sepia melanin at various concentrations was added primary human keratinocyte (HGK) monolayers identify concentrati...

Recent observations of coherent radiation from the Crab pulsar (Bij et al 2021) suggest emission is driven by an ultra - relativistic ($\gamma \sim 10^4$), cold plasma flow. A relativistically expanding shell can compress ambient magnetic field, like a moving mirror, and thus produce whose wavelength shorter than that medium $\gamma^2$. This mechanism has been studied in past Colgate Noerdeling...

The aim of this study was to evaluate the effect using dentifrices containing tricalcium phosphate (β-TCP) on microhardness, enamel color, and topography before bleaching treatment with 35% hydrogen peroxide (HP). Fifty bovine incisor enamel/dentin blocks (4 × 4 2 mm) were randomized into five groups (n=10): (C) negative control (no treatment), positive (35% HP), Colgate Total 12 then HP (CT + ...

The shortage of faculty in dental education is well documented, but the data also show a shortage of minorities in postgraduate programs, which develop future faculty. In the last ten years, ADEA's effort to address minority issues in dental education has made some progress. In addition, examples of pipelines for minority faculty development that have shown some success include: a partnership b...

This study evaluated the in vitro antibiofilm effect of 5 different commercial mouthwashes (Cepacol Traditional, Colgate Plax Fresh Mint, Listerine Cool Mint, Oral-B Complete, and Sensodyne) on Candida albicans, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans, Escherichia coli, and Pseudomonas aeruginosa. The cytotoxic effect of the mouthwashes on gingival fibroblasts was als...

BACKGROUND This subject-blind randomized clinical trial tested the efficacy of a new 5 percent sodium fluoride varnish (AllSolutions Fluoride Varnish, Dentsply Professional, York, Pa.) for treatment of cervical dentin hypersensitivity. The authors also compared the test varnish with a control fluoride varnish (Duraphat, Colgate Oral Pharmaceuticals, New York City). METHODS The study involved ...

Since the currently available pH-cycling models do not differentiate the anti-caries potential of dentifrices with low fluoride (F) concentration, two models were developed and tested in the present. Bovine enamel blocks were subjected to the models and treated with F solutions containing from 70 to 280 microg F/mL in order to validate them in terms of dose-response effect. The models were also...

BACKGROUND Toothpastes are considered as one of the most common and usable cosmetic and hygienic materials. Such materials contain chemicals which may have an adverse effect on oral tissue in humans. The present study aimed to compare the toxic effect of current commercial toothpastes including Iranian products and imported types which are consumed globally on oral epithelial- and HeLa cells as...

The annual U.S. News and World Report (USNWR) Guide to America’s Best Colleges is a much anticipated magazine among both high-ability prospective students and college and university administrators. In this paper we use a decade of Colgate University Admitted Student Questionnaire surveys to estimate the influence of changes in a school’s USNWR rank on the probability of matriculation of high-ab...

This review details the invention and clinical testing of a new power toothbrush designed to provide a low cost, effective toothbrush, which has a combination of a round oscillating head in conjunction with fixed bristles. The data demonstrate this power toothbrush (Crest SpinBrush) is an effective cleaning toothbrush with respect to plaque removal. Four independent 4-period crossover studies, ...
