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 ...
Together with periodontal curettes, periodontal scalers are used to remove calculus from teeth. While curettes are often universal in that they can be used on both supra- and sub-gingival calculus removals, scalers are restricted to supra-gingival use. [1] Use of a scaler below the gum line is likely to damage the gingiva (gums). [2]
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 ...
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. [ 44 ]
The calculus of the oral cavity is the result of mineralization of and around dead microorganisms; this calculus can then be colonized by living bacteria. Dental calculus can be present on supragingival and subgingival surfaces. [8]
Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, [1] the agents that ...
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.
