The article explores the role of bacterial growth and crystal formation in the formation of calculus. In one experiment the author divided a beef heart infusion agar into two portions, added dextrose to one of these, then sterilized and poured plates from both. Two additional experiments are described as well, and results for all are discussed.

    A definition of the term "scale" is presented. It refers to a small dry flake, shed from the upper layers of skin. It also refers to a film of tartar encrusting the teeth. The term is also used to remove a film of tartar from the teeth. It refers to form a scale on and is also used to shed scales.

    Protease activity was measured in dental plaque collected from patients with or without supragingival calculus. Plaque specimens from the calculus group showed significantly greater protease activity in the presence of 0.05% sodium thioglycollate than did those from the non-calculus group. No...

    Most animal models for the study of calculus accumulation and control currently use rodents or dogs. In an effort to overcome limitations inherent in the use of these species, we investigated calculus formation in domestic ferrets, a species used by King et al. in the 1940's and 1950's. Ferrets...
