CSA local antimicrobials in perio Flashcards
what is mechanical therapy to remove perio. pathogens?
- scraping near roots
- patients cleaning their teeth
Limitations of mechanical therapy?
- ## teeth with furcation involvement show poor treatment outcome
Why mechanical therapy may fail to remove pathogens?
- microbes trapped
Where can microbes get trapped?
- sub epithelial gingival tissue
- crevicular epithelial cells
- within CONNECTIVE tissue
- altered cementum and dentinal tubules
- sub gingival calculus
- DEEP grooves
- tongue, tonsils and oral mucosa
what is a locally delivered antimicrobial?
0.2% chlorhexidine gluconate:
In perio. disease is there a high volume of GCF?
Yes
Are all local delivery devices degradable?
YES apart from Actisite
How to measure treatment outcomes?
PPD
Gingival recession
Clinical attachment level
BOP
why can there be a change in pocket depth after treatment?
attachment tissue being reformed or inflammation of gingivae is resolving
what is a reliable tool to indicate perio. stability?
absence of BOP
WHAT IF patient has pockets > 3mm with NO BOP
OHI and scaling
WHAT IF patient has pockets > 3mm with BOP
scaling and RSD
What is actisite?
long ethylene vinyl acetate fibre loaded wit 25% tetrracycline
how does actisite work?
bactericidal, layered within pocket and adhesive placed around tooth neck
when is acitisite removed?
after 10 days, its difficult to place
