Efficacy of Chitosan Irrigation for Pulpectomy in Non-Vital Primary Teeth:A Clinical-Radiographic Study

Research Abstract

ABSTRACTIntroduction:Despite the antibacterial properties of sodium hypochlorite (NaOCl), it is cytotoxic and cannot effectivelyremove the smear layer. Chitosan is a natural nontoxic biopolymer having antimicrobial properties.Aim:Clinical and radiographic assessment of 0.2% chitosan as final irrigating solution in pulpectomy in non-vital primaryteeth for 1 and 3 minutes versus sodium hypochlorite.Methods:A randomized clinical trial included 45 non-vital primary molars in 43 patients aged from four to seven years oldwere randomly divided into 3 equal groups. In Group I (control group), 2 ml of 1% NaOCl was used for irrigation after eachfile. In Group II, 5 ml of 0.2% chitosan was used as final irrigat and left in the canal for one minute. While in group III chitosanwas left in the canal for 3 minutes. Clinical Assessment was performed regarding pain on percussion and changes inmucobuccal fold. Radiographical evaluation was done at 3,6,12 months follow up intervals using standardized periapicalradiographs and analyzed using Image J program.Results:Studied teeth were recorded as first primary molars (D) and second primary molars (E) with total percentage foreach group (I, II and III). Although the high clinical and radiographic success rate, there was no significant difference betweenthe three groups.Conclusion:Pulpectomy irrigation using either NaOCl alone or chitosan as a final irrigant for one or three minutes exhibiteda good clinical and radiographic success rate with no significance difference.
