Sponsor: Cairo University
Summary
The primary aim of the study is to compare the bacterial reduction in pulpectomy of primary molars using a single rotary file system versus conventional manual instrumentation.

Rotary Instrumentation
After opening the access cavity, the root canal patency will be checked for all the canals located using a size #15 (0.02%) K file, then a single rotary file (AF F One, FANTA, China) (20 taper 4) will be adjusted to the desirable working length depending on an electronic apex locator (1 mm shorter than the apex). This file will be used in the pulpectomy procedure using a brushing motion and will be irrigated with saline.
Manual Instrumentation
After opening the access cavity, manual files (K files, Mani, Inc., Japan) of sizes 15, 20, 25, and 30 will be adjusted to the desirable working length depending on an electronic apex locator (1 mm shorter than the apex). These files will be used in the pulpectomy procedure using a brushing motion and will be irrigated with saline.
