Calculus can form both along the gumline, where it is referred to as supragingival (' above the gum '), and within the narrow sulcus that exists between the teeth and the gingiva, where it is referred to as subgingival (' below the gum '). Calculus formation is associated with a number of clinical manifestations, including bad breath, receding ...
After supra-gingival oral hygiene cleaning, plaque biofilm will quickly develop at the gingival margin and will enter the gingival sulcus after some time. The junctional epithelium, which is at the base of the gingival sulcus, permits plaque bacteria and its toxin to enter the underlying gingival connective tissue via the large spaces between ...
The bundle branches were separately described by Retzer and Braeunig as early as 1904, but their physiological function remained unclear and their role in the electrical conduction system of the heart remained unknown until Sunao Tawara published his monograph on Das Reizleitungssystem des Säugetierherzens (English: The Conduction System of the Mammalian Heart) in 1906.

Gracey curettes are area-specific periodontal curettes made from stainless steel used to remove supra and subgingival calculus. [3] [5] Along with universal curettes, Gracey curettes are one of the main instruments used for scaling and root planing. Gracey curettes are especially ideal for subgingival calculus removal because the design of the ...
The periodontal therapy carried out at this stage is of a non-surgical approach, which is aimed at the removal of supra- and sub-gingival plaque and calculus deposits, to decrease the microbial load, bacteria biofilm, and calculus from the periodontally involved sites.

An 11/12 type explorer is a double-ended dental assessment instrument with mirror image working-ends. [4] The 11/12 dental explorer should be considered a dental hygienists most important instrument for the detection of subgingival and supragingival calculus.
It requires a few appointments, depending on time and clinician skills, for effective removal of supragingival and subgingival calculus, when periodontal pockets are involved. It can assist in periodontal healing and reduce periodontal pocketing by changing the subgingival ecological environment. [ 45 ]
Dental plaque is a biofilm that attaches to tooth surfaces, restorations and prosthetic appliances (including dentures and bridges) if left undisturbed.Understanding the formation, composition and characteristics of plaque helps in its control. [6]
