“…The rate of calculus formation, and its composition, may differ depending on the intra‐oral localization. Dental calculus in close proximity to the openings of the large salivary gland ducts contains more calcium and phosphorus than does dental calculus that develops at other intra‐oral sites (Fig. ).…”

Dental calculus represents the first fossilized record of bacterial communities as a testimony of evolutionary biology. The development of dental calculus is a dynamic process that starts with a nonmineralized biofilm which eventually calcifies. Nonmineralized dental biofilm entraps particles from the oral cavity, including large amounts of oral bacteria, human proteins, viruses and food remnants, and preserves their DNA. The process of mineralization involves metabolic activities of the bacterial colonies and strengthens the attachment of nonmineralized biofilms to the tooth surface. From a clinical point of view, dental calculus always harbors a living, nonmineralized biofilm, jeopardizing the integrity of the dento-gingival or implanto-mucosal unit. This narrative review presents a brief historical overview of dental calculus formation and its clinical relevance in modern periodontal practice.

“…This buffer has been proposed for fluoride analyses of calcified dental tissues [McCann, 1968]. As plaque contains less calcium and phosphorus [Jenkins, 1965] than calci fied dental tissues [Trautz, 1967], 1 ml of a 1.0 m trisodium citrate solu tion was considered sufficient to eliminate interferences (tables V, VI).…”

A method using an Orion combination electrode (96–09) was developed for determining the total fluoride content of soft tooth deposits. The samples were collected by plastic sealers and dried at 105° C. After weighing, the sample was dissolved in a small polypropylene tube, positioned inside a larger tube. The dissolution was carried out in 0.2 ml of a mixture of HClO₄ and HNO₃ at 60° C for 2 h. The outer tube contained 0.3 ml NaOH and 1 ml Na₃-citrate. After the soft deposit was dissolved, the contents of the tubes were mixed without opening the sealed outer tube. The final mixture had a pH of 5.8 and the F^–– was determined directly. The recovery was found to be satisfactory. Known amounts of F added to dried deposits of Streptococcus salivarius and to Ca₃(PO₄)₂ indicated no F- binding in the solubilized material. Deposits collected from a group of children 5–6 days after mouthrinsing with 0.2 % NaF had an average fluoride concentration of 85 ppm F (on dry weight) as compared to 52 ppm F in the control group.

“…Attempts to relate micromorphological observations with chemical data on the crystalline inorganic constituents of early calculous plaque (Schroeder & Bambauer, 1966) encounter serious difficulties due 1) to the nonhomogenous distribution of calcium phosphate containing foci within plaque, and 2) to the content of organic phosphorus. The chemistry of the total plaque has been summarized by Jenkins (1965…”
