Recently we reported that feline and canine dental calculus fluoresced pink to red under long wavelength ultraviolet light due to the presence of porphyrin.1 Here we report the observation of such fluorescence in 30 of 30 cats, 30 of 30 dogs, and 8 of 13 supragingival samples and 5 of 5 subgingival samples of humans.

Abstract The inorganic chemical and crystallographic composition of seventy-three dental calculus samples of known origin has been investigated. The findings showed the average ash content to be 77%. Calcium, phosphorus, magnesium, fluoride and carbon dioxide averaged 34, 19, 0.9, 0.05 and 1.8% respectively on an ash weight basis.

Tobacco smoking and supragingival dental calculus
Journal of Clinical Periodontology, 1999Abstract. Supragingival calculus is frequent in all ages from adolescence to old age. The influence of tobacco smoking on the occurrence and severity of supragingival calculus has received surprisingly little attention. The present investigation conducted in a population of 258 dentally aware individuals in the age range 20–69 years, was initiated to ...

Tobacco smoking and subgingival dental calculus
Journal of Clinical Periodontology, 2005AbstractObjective: A radiographic investigation into the relationship between tobacco smoking and subgingival dental calculus was conducted in an adult population, including 48 current smokers, 57 former smokers, and 125 non‐smokers.Material and Methods: Assessment of subgingival calculus was based on a full set of radiographs. Mesial and distal root
