Clinical Evaluation of Chitosan as Final Irrigating Solution for Pulpectomy in Non-Vital Primary Teeth
Main Article Content
Abstract
Introduction: Chitosan has antibacterial properties and has a high capacity for chelating various metal ions.
Aim of the study: To clinically assess 0.2% chitosan for 1 and 3 minutes as final irrigant solution for pulpectomy in non-vital deciduous teeth versus sodium hypochlorite (NaOCl).
Patients and methods: This study is a randomized clinical trial, directed on 43 children aged from 4-7 years old. Forty-five non-vital primary molars were categorized into three equal groups. In Group I (control group), 2 ml of 1% NaOCl was used for irrigation after each file. In Group II, 5 ml of 0.2% chitosan was used as final irrigating solution and left in the canal for one minute. While in group III chitosan was left in the canal for 3 minutes. Clinical evaluation regarding spontaneous pain and tooth mobility was done for all patients preoperative, postoperative and after 1,3,6,12 months intervals.
Results: None of the cases in groups I and III showed pain or tooth mobility in all follow-up periods. Only one positive case was found in group II at 3 months interval. The difference between the three groups was insignificant.
Conclusion: Irrigation in pulpectomy with either NaOCl only or with chitosan as a final irrigating solution for 1 and 3 minutes, showed high clinical success rate with no significance difference.
