Abstract
Introduction: The goal of this study was to evaluate the effectiveness of different irrigation solutions on the removal of calcium hydroxide, Chlorehexidine and Lycopene mixture from the root canals by NaOCl, EDTA alone or combination of NaOCl and EDTA. Materials and Methods: Thirty eight single rooted teeth were taken. Root canals were prepared by standardized instrumentation up to Master Apical File 45 and irrigated with 2.5% NaOCl after each instrument, followed by 10 mL 17% EDTA as a final rinse. The canals were filled with Calcium hydroxide, Chlorehexidine and Lycopene mixture and stored for 7 days. Specimens were randomly divided into 3 experimental groups (n = 10) according to irrigation protocols. Positive and negative control groups (n = 4) were included. Group 1: the root canals were irrigated with 5 mL 2.5%Naocl, group 2: the root canals were irrigated with 5 mL 17% EDTA, Group 3: the root canals were irrigated with 2.5 ml Naocl and 2.5 ml EDTA. The specimens were longitudinally sectioned and evaluated with scanning electron microscope and scored by 2 examiners. .Results: The kappa test showed that there was substantial agreement between the 2 examiners values for scoring the calcium hydroxide dressing in the coronal, middle, and apical thirds in each group. All irrigation regimens left debris on the canal walls. Among all the groups, NaOcl and EDTA combination is efficacious in removal of calcium hydroxide dressing from the root canal followed by EDTA, NaOCl in coronal, middle and apical thirds.( P< 0.05)Conclusion: According to the findings of the present study, combination of NaOCl and EDTA could be used effectively for the removal of Calcium hydroxide, Chlorehexidine and Lycopene mixture from the root canals.
