Operating steps:1.Establishing appropriate root canal entrance and using #15 stainless steal K file to establish the guiding path of reaching working length.
2.About upper preparation,using SX file to open upper root canal,then starting motor after root canal file enters into root canal orifice,under passive pressure it will prepare to form
3.Firstly use EDTA to lubricate root canal,then start motor and do lifting movement 3-4 times to prepare 1/3 root canal within 3-5 seconds.After rinsing with sodium hypochlorite,then use stainless steel K file to prepare from apice file to #15 and #20.Every time it need to reach exact working length and rinse with sodium hypochlorite.The EDTA is filled with pulp chambers and root canals,then start motor after S1 enters into root canal orifice.The technique is to move along the root canal to the root tip.Root canal file need to do upper and lower pulling movement3-5 times after it reaches the working length,then rinse with sodium hypochlorite.
SX-F3: speed is 250-350rpm
IMPORTANT INSTRUCTION : WE SUGGEST U TO DO COLD STERLIZATION OF BLUE AND GOLD FILES. IT HELP U TO INCREASE FILES LIFE.
