Aim: To evaluate the disinfection of dentinal tubules using calcium hydroxide with propylene glycol and calcium hydroxide with iodoform in silicone oil, as compared to 2% chlorhexidine gel. Materials and Methods: The antimicrobial efficacy of the medicaments against E.faecalis and C.albicans were assessed in vitro, using a dentinal tubule model at depths of 200 μm and 400 μm in extracted single rooted teeth. Saline was taken as the negative control (Group I) Results: All three medicaments used in this study exerted antibacterial and antifungal activity. Group II (calcium hydroxide with propylene glycol) and Group IV (2% chlorhexidine gel) had the highest antimicrobial activity and the differences between their antibacterial activities were not statistically significant. Group III (calcium hydroxide with iodoform in silicone oil) and Group IV had the highest antifungal activity and the differences between their antifungal activities were not statistically significant. The inhibition of growth at 200 μm and 400 ΅m was uniform, with no statistical difference. Conclusions: Two percent chlorhexidine gel was effective against both E.faecalis and C.albicans. Calcium hydroxide with propylene glycol was the most effective intracanal medicament along with 2% chlorhexidine against E.faecalis, whereas, calcium hydroxide with iodoform in silicone oil was the most effective intracanal medicament along with 2% chlorhexidine against C.albicans.
