Evidence for food, cooking, and medicinal plants entrapped in dental calculus
In addition to yarrow and camomile, the dental calculus study identified an oil shale or bitumen source, a range of different carbohydrates, evidence for cooking, what may have been green vegetables and nuts, and inhalation of wood smoke or smoked food, but no evidence for meat ingestion despite evidence for collagen survival (Hardy et al.
Charred edible plant remains have been found on several Neanderthal sites (Jones 2009) and plant microfossils have been found in samples of Neanderthal dental calculus (Henry et al.
The presence of dental calculus
was evaluated dichotomically (present or absent) in the buccal, palatinal/lingual or occlusal surfaces.
was the original etiologic agent associated with development of chronic periodontitis.
CPI scores were listed as 0, 1, 2, 3 and 4 to indicate, respectively, the following conditions: healthy, bleeding after probing, dental calculus
detected by probing, 4- to 5-mm deep pockets and >6-mm deep pockets.
Researchers from Spain, the UK and Australia combined pyrolysis gas-chromatography-mass spectrometry with morphological analysis of plant microfossils to identify material trapped in dental calculus
(calcified dental plaque) from five Neanderthals from the north Spanish site of El Sidron.
Summary: TEHRAN (FNA)- While we may brush and floss tirelessly and our dentists may regularly scrape and pick at our teeth to minimize the formation of plaque known as tartar or dental calculus
, anthropologists may be rejoicing at the fact that past civilizations were not so careful with their dental hygiene.
The smooth polishing, evidence of repetitive biting and chewing, and presence of dental calculus
, implies that it had been a functional prosthesis.
Perhaps the most astonishing results came from clinical tests conducted by an independent lab in Pennsylvania to determine the efficacy of GREENies in preventing accumulation of dental calculus
