Chemical control of supragingival plaque Flashcards
1
Q
Classification of elements that inhibit the formation of supra-gingival plaque-according to mechanism of action
A
- Antiadhesive
- Antimicrobial
- Plaque removal
- Antipathogenic
2
Q
Antiadhesive
A
- Acts at pellicule surface
- Interferes w/ bacterial matrix formation
3
Q
Antimicrobial
A
- Inhibits primary plaque proliferation
- Bactericidal
4
Q
Plaque removal
A
- Mechanical removal-brush combined w/antimicrobial mouthwash
5
Q
Antipathogenic
A
- Inhibits pathogenicity of microorganisms w/out destroying them
6
Q
Methods of plaque control
A
- Toothpastes
- Mouthwashes
- Sprays
- Irrigators
- Chewing gum
- Varnishes
7
Q
Effectiveness of chemical plaque control agents depends on
A
- Adsorption and prolonged retention on oral surfaces
- Bacteriostatic/bactericidal action
8
Q
Chlorhexidine characteristics
A
- Gluconate, acetate, hydrochloride salts
- Antimicrobial
- Cationic nature=>miminises absorption through skin and mucosa
9
Q
Side effects of chlorhexidine
A
- Discolouration
- Taste affected
- Mucosal erosion
- Uni/bilateral parotid swelling
- Increased supragingival calculus germination
10
