Assessment of Post-operative Pain After Different Instrumentation Techniques in Pulpectomy Treatment of Primary Molars

the patient will be anesthetized by local anesthesia. the rubber dam will be used for isolation. caries will be removed using high speed handpiece. determination of working length using apex locator. the canal patency will be checked with a # 10 K file, and gliding path until #15 K- file. the root canals of primary molars will be cleaned and shaped in pulpectomy treatment using the adaptive xp endo shaper. it is single file technique saves time and help with patient cooperation . the endomotor will be activated at aspeed of 800 rpm and 1 Ncm torque. the canals will be irrigated using 2.5% Nacol ending with 0.9% normal saline canal irrigation. the canals will be dried with paper points and obturated with Metapex. teeth will be restored by glass ionomer restoration than stainless steel crown.

The canal patency will be checked with a #10 K-file, and a glide path until #15 K-file will be created .the root canals of primary molars will be cleaned and shaped in pulpectomy treatment using FANTA AF baby files. it is pediatric rotary system consists of 4 files specialized for primary molars.Open file: #17, taper 08.~* BTF1: #20, taper 04, Yellow~* BTF2: #25, taper 04, Red~* BTF3: #30, taper 04, Blue The file will be activated at speed 350 rpm and torque 2 N until reaching the full working length. the canals will be irrigated using 2.5% Nacol ending with 0.9% normal saline canal irrigation. the canals will be dried with paper points and obturated with Metapex. teeth will be restored by glass ionomer restoration than stainless steel crown."

the patient will be anesthetized by local anesthesia. the rubber dam will be used for isolation. caries will be removed using high speed handpiece. determination of working length using apex locator. the root canals of primary molars will be cleaned and shaped in pulpectomy treatment using hand k files starting with #15 stainless steel hand K file. they are manual files, they are standard for root canal treatment (control group). the canals will be irrigated using 2.5% Nacol ending with 0.9% normal saline canal irrigation. the canals will be dried with paper points and obturated with Metapex. teeth will be restored by glass ionomer restoration than stainless steel crown.
