Abstract

Background: The present study was conducted for evaluating and comparing two different
root canal irrigating solutions during root canal therapy.Materials & methods:Assessment
of 20 freshly extracted mandibular first premolar were obtained and were broadly divided
into two study groups with 20 specimens in each group; Group 1- Root canals irrigated
using 2.5% NaOCl for 1 min only, and Group 2- Root canals irrigated with 2% CHX
gluconate for 1 min followed by 3 ml of 2.5% NaOCl solution. The cleaning ability of
irrigating solutions was evaluated using the smear layer score system. All the results were
recorded in Microsoft excel sheet and were analyzed by SPSS software.Results: Mean
smear layer score among specimens of group A and group B was 4.5 and 4.2 respectively.
Non-significant results were obtained while comparing the mean smear layer score.
Conclusion:From the above results, the authors concluded that both the irrigating
solutions are equally effective in removing smear layer.
