The phrase "amount of calculus" is correct and usable in written English.
It can be used when discussing the quantity or extent of calculus involved in a particular context, such as a course, problem, or application.
Example: "The amount of calculus required for this physics course is significantly higher than in previous semesters."
Alternatives: "level of calculus" or "quantity of calculus".
Besides "enormous amounts" of academic reading and two essays that were due the first day of school, he had "a crazy amount of calculus problems to tackle". Four of the five Advanced Placement courses he took this school year required work last summer, he said.
Hence, high amount of calculus indicates that oral hygiene has been poor for months or even years [ 14].
It needs to be reemphasized that in the subjects who had been healthy in the 1985 examination and also had then no signs of oral diseases but who had died by the year 2011, a voluminous amount of calculus had been accumulating in their gingival crevices.
Therefore, none of these variables confounded the association observed between age, gender, amount of dental calculus, and cardiac death.
The specific aim was to investigate in our 26-year prospective study whether the amount of dental calculus is associated with cardiac death.
We studied whether the amount of dental calculus is associated with death from heart infarction in the dental infection atherosclerosis paradigm.
Based on our results, high amount of dental calculus over time may play a role in premature death in heart infarction.
Each of these indexes in turn, is based on numerical determinations representing the amount of debris or calculus found on the preselected tooth surfaces.
The amount of DNA extracted from calculus can be 3 orders of magnitude greater than that obtained from bone or dentine (Adler et al. 2013; Warinner et al. 2014a, b, c), and the tandem mass spectrometric-based analyses for protein has allowed fragments of protein to be interpreted, according to the deduced amino acid sequences of peptides (Warinner et al. 2014a).
When dentin is strongly degraded and the relative proportion of host DNA in dentin is very low (<0.1%), the absolute amount of human DNA within dental calculus can exceed that of dentin.
The total amount of DNA recovered from dental calculus is substantially higher than from dentin as measured by both fluorometric quantitation (Qubit) (Fig. 2a) and quantitative PCR (qPCR) (Fig. 2b).
