This Comparative Randomized in-Vitro study was conducted to compare the antibacterial effect of two different herbal extracts: Cinnamon Zylanicum (True Cinnamon) and Azadiracta Indica (Neem) versus Calcium Hydroxide (Ca (OH) 2) as an intracanal medication against Enterococcus Faecalis (E. faecalis) in single-rooted premolars teeth. Thirty nine single-rooted premolars teeth were randomly divided according to the intracanal medication used into three groups (n=13), either True Cinnamon or Neem or Ca (OH) 2. The teeth were decronated, infected with E. faecalis and incubated for 21 days, then Pre-operative sample (S1) was taken using size 25 sterile paper points. The root canals were prepared using ProTaper Universal rotary system till size F4, then Post-Instrumentation sample (S2) was taken using F4 sterile ProTaper paper points; this was followed by the application of the intracanal medications for 7 days, then the Post-medication sample (S3) was taken using F4 sterile paper points. The antibacterial effect was assessed using Agar Diffusion Test to count the colony forming units. Results showed that there was no difference in the antibacterial effect of True Cinnamon, Neem and Ca (OH) 2, however in each group there was a statistically significant difference in the antibacterial effect between the Pre-operative samples (S1), the Post-Instrumentation sample (S2) and the Post-medication sample (S3)
