Definition of acquired pellicle
layer of glycoprotein deposited from salivary and crevicular fluids that is strongly bound to the tooth surface
Definition of calculus
concentration composed of calcium phosphate, calcium carbonate, magnesium phosphate, and other elements within an organic matrix composed of desquamated epithelium, mucin, microorganisms, and other debris that adheres to tooth surfaces
Definition of first molar loss
syndrome that has not been proven to initiate periodontal disease but that is associated with gingival inflammation and pocket formation as the condition progresses
Definition of food impaction areas
areas of the teeth and oral tissues in which food becomes lodged; occur inter proximally because of open contact areas
Definition of lingual groove
furrow or channel that forms on the tongue side of selected front teeth
Definition of pyrophosphate
compound found in parotid saliva that helps delay calcification of bacterial plaque
Definition of risk factor
exposures, behaviors, and characteristics associated with a disease
Definition of risk indicator
behavior that causes a person to have a greater likelihood of disease
Definition salivary duct calculus
calculi that can form and block the openings of major and minor salivary ducts, referred to as sialoliths or salivary stones
Definition of serumal calculus
another name for sub gingival calculus
Definition of sub gingival calculus
calculus deposited on the tooth structure and found apical to the gingival margin within the confines of the gingival cervix, gingival pocket, or periodontal pocket
Definition of submarginal calculus
another term for sub gingival calculus
Definition of supra gingival calculus
calculus deposited on the teeth occlusal or incisal to the gingival crest
Definition of tartar
common name for dental calculus, often used by patients when referring to calculus
Supragingival calculus is primarily composed of
.
Calculus is a major causative factor in the formation of periodontal disease. Subgingival calculus covered with plaque does not contribute to greater disease progression
.
Anticalculus toothpastes reduce the formation of new supra gingival calculus due to which agent?
.
Amalgam restoration discrepancies are detrimental to periodontal health because they serve as a sheltered place for plaque and calculus growth
.
All of the following statements regarding calculus removal are true EXCEPT one. Which one is the EXCEPTION?
.
Routine plaque control can be complicated for the periodontal patient by poorly aligned teeth. Orthodontic therapy will cause severe periodontal disease in children and teenagers
.
All of the following characteristics may be related to calculus formation EXCEPT one. Which one is the EXCEPTION?
.
Smoking and the use of tobacco products are considered risk
