-
white, creamy yellow, or gray, may be stained by tobacco, food or other pigments; slight deposits may be invisible until dried with compressed air
supragingival calc
-
light to dark brown, dark green, or black; stains derived from blood pigments from diseased pockets
subgingival calc
-
amorphous, bulky; gross deposits may form interproximal bridge between adjacent teeth or extend over the margin of the gingiva; shape of calc mass is determined by the anatomy of the teeth, contour of the gingival margin, and pressure of the tongue, lips, and cheeks
supragingival calc
-
flattened to conform with pressure from the pocket wall; combination of the following calc formations occur: crusty, spiny, or nodular; lege, or ring like; thin, smooth veneers; finger and fern like; individual calc islands
subgingival calc
-
moderately hard; newer deposits less dense and hard; porous surface covered with nonmineralized biofilm
supragingival calc
-
brittle, flintlike; harder and more dense; newest deposits near bottom of pocket are less dense and hard; surface covered with dental biofilm
subgingival calc
-
quantity has a direct relationship to: personal oral care procedures and biofilm control measures; physical character of diet; individual tendencies; function and use; increased amount in tobacco smokers
supragingival calc
-
related to pocket depth; increased amount with age because of accumulation; quantitiy is related to personal care, diet, and individual tendency as it is with the other; it is primarily related to the development and progression of periodontal disease
subgingival calc
-
coronal to margin of gingiva; may cover a large portion of the visible clinical crown, or may form fine thin line near gingival margin
supragingival calc
-
apical to margin of gingiva; extends to bottom of the pocdket and follows contour of soft tissue attachment; with gingival recession; this calc may become the other and become covered with typical other calc
subgingival
-
symmetrical arrangement on teeth, except when influenced by: malpositioned teeth, unilateral hypfunction, inconsistent personal care, abrasion from food; occurs with or without associated other composits; location related to openings of the salivary gland ducts; facial surface of maxillary molars; lingual surface of mandibular anterior teeth
supragingival calc
-
heaviest on proximal surfaces, lightest on facial surfaces, occurs without associated other deposits
