GCF increase factors
inflammation
main reason
smoking
in the long term decrease GCF
circadian periocity
influence of sex hormone
chewing on coarse foods
gingival masage
vigorous tooth brushing

MICROPIPETTES
based on capillary action
INTRACREVICULAR WASHINGS
peristaltic pump
paths to collect GCF
ejection-collection needle
PREWEIGHED TWISTED THREADS
based on weigh difference

ANTIBACTERIAL PROPERTIES
complement components
antibodies
enzymes
leukocytes
CLEANSING ACTION
flushing out bacteria
shed epithelial cells
ADHESIVE
adhesion of the junctional epithelium to the tooth
by mean of adhesive plasma proteins
Drug in GCF
tetracycline
metronidasole
antibiotic
