Week 4 Ch 18: Preventive and Desensitizing Materials

cariogenic

substances or microorganisms that promote dental caries

demineralization

action that removes mineral from the tooth, usually caused by acids

fluorapatite

tooth mineral that results when fluoride is incorporated into the tooth

fluoride

naturally occurring mineral that helps protect tooth structure from dental caries

fluorosis

enamel condition caused by consumption of excessive levels of fluoride

remineralization

process that replaces mineral lost from the tooth due to an acid attack

antimicrobial mouthrinse

liquid used to rinse the oral cavity to reduce or suppress bacteria associated with dental caries or periodontal disease

desensitizing agent

a chemical that seals open dentinal tubules to reduce tooth sensitivity to air, sweets and temperature changes

erosion

loss of tooth structure caused by dietary or gastric acids, not by bacterial metabolism (caries process)

sealant

a protective resin that is bonded to enamel to protect pits and fissures from dental caries

substantivity

property of a material that has prolonged therapeutic effect after its initial use

severe fluorosis

mottled enamel; brown staining and pitting of the enamel surface

0.05-0.07 mg/kg/day

what is recommended daily intake of fluoride?

5mg/kg

what is probable toxic dose of fluoride intake?

32-64mg/kg

what is certain lethal dose of fluoride intake?

chlorhexidine

reduces plaque by 55%, gingivitis by 45%; must be used daily for 2 weeks straight to be effective; FDA approved mouthrinse

listerine

phenolic compound; antibacterial action is the alteration of the bacterial cell wall; reduction of plaque scores by about 25% and gingivitis by 50%

potassium nitrate, strontium chloride, zinc chloride

which agents aid in decreasing sensitivity?
