DG16

Question 5

0 reading on electronic apex locator

Answer 5

indicates PDL
remove 0.5-1mm from this to calculate CWL

Question 6

discuss apical taper of modified double flare

Answer 6

use one file size larger than master apical file.
prep to 1mm less than CWL
R/I/P
then one size less and repeat until desired file goes passively to desired length
master apical file then used to smooth prep
