1.Every time you change a file,please ensure to lubricate with enough EDTA frequently.(veryimportant!!)
2.Anterior teeth:20 root canals
3.Posterior teeth:15 root canals (or 5 posterior teeth)
4.Preparation of the sharp curved root canals dose big damage to the instrument,werecommend one-time use."
"GUIDELINES FOR USE
1.Measure the length & negotiate the canal by #10 stainless steel K FILE
2.Negotiation by #15 stainless steel K files
3.OPEN FILE to open the upper1/3 part of orifice.Speed 300rpm,Torque 3.0N.cm
4.Irrigate,then build a glide path by PATH FILE #19.Speed 350rpm,Torque1.5N.cm
5.Use brushing motion with G3PG-1(white), G3PG-2（red),G3PG-3（double red), G3PG-4(green) and short 1-2 mm amplitude strokes to prepare to working length,until it does not easily prigress any more.Speed 350rpm,Torque 2.0/1.5/1.5N
6.It is very important to irrigate and negotiate the root canals with suitable interval when near1/3 of the apical to remove the debris.Repeat the above steps until prepare to the working
