PURPOSE This study assessed the anti-calculus benefit of Crest Dual Action Whitening Toothpaste in gastrostomy (GT) children compared to a control anti-caries dentifrice. METHODS A double-blind randomized crossover design was used to compare the two dentifrices. A convenience sample of 24 GT subjects, 3-12 years old, was given a consensus baseline Volpe-Manhold Index calculus score by 2 train...

Dental calculus (calcified dental plaque) is a cross-cultural biological matrix that emerging as critical source of information for anthropologists and oral health professionals. It contains multitude diverse biomolecules, providing about an individual’s culture, diet, ancestry, health. Most researchers who study archaeological use genomic or proteomic approaches, although wide range other tech...

This work presents elemental composition studies of human dental calculus by X-ray fluorescence analysis using synchrotron radiation. The intrinsic characteristics of synchrotron light allow for a quantitative analysis of major, minor, and trace elements of very small samples in a single measurement. At present, several theories of calculus formation exist, but none of them can describe complet...
