Evaluation of Antimicrobial, Post Operative Pain of Cinnamon Extract Versus Sodium Hypochlorite Irrigant Following Pulpectomy of Primary Teeth

Preservation of primary teeth with non-vital pulp is a major problem in pediatric dentistry, as it is a poly-microbial and dominated by obligatory anaerobic bacteria. Regarding these case preferable treatment modality is pulpectomy . The objective of pulpectomy is complete removal of necrotic and irreversibly infected pulp of an affected tooth but due to limited ability of mechanical preparation to eliminate entrapped micro-organisms in the canal space owing to the tortuous and complex nature of the root canal system .Thus, the use of antimicrobial agents has been recommended as an adjunct to mechanical instrumentation in deciduous teeth . Due to potential side effects, safety concerns of synthetic drugs and cytotoxic reactions of commercial intra canal irrigants and their limited ability to eliminate bacteria from dentinal tubules . Finding the best irrigating solution for endodontic therapy in primary and permanent teeth is still a working progress .There is a growing interest in using sustainable products of natural origin as an alternative to commercially available industrial ones .Cinnamon , which has gained popularity in recent time due its antibacterial , antifungal , anti-inflammatory & antiseptic activity . It has shown effectiveness against S. mutans and E. fecalis organisms . It is also known to show a wide spectrum of action on gram positive and gram negative bacteria .
