K3-Lightspeed case.
Tooth #30 (46 int.); 4 canals; apical periodontitis; 2 visits; Ca(OH)2.
Patency obtained and maintained on all canals.
Sequence: K3#25/.10, #25/.08, #25/.06, #25/04, #20/.04. Mesials needed
a repeat of the sequence. This K3 sequence appears to be quite effective,
without removing too much coronal tooth structure. You can also use
the #25/.08 "body shaper" again at the end for deeper shape!
LightSpeed 12 peck rule: MAR's--MB & ML = #50; Db & DL = #52.5
Endo-Rez; warm vertical SystemB, Obtura. I fit the master cones about
0.5mm short of the bleeding points.
I think some pecking with the Lightspeed files are absolutely required,
rather than just gauging. If you just use the LS files as "gaugers"
they will just tell you the narrow diameter of a non-circular canal.
Trying to "round" it out by rotating the LS files will give you a cleaner
canal by debriding the "out of round" apical areas - Fred Barnett
