Abstract
AIM : This study aims to compare the smear layer removal efficacy of the chelating agent chitosan(C), 10% citric acid(CA) and 17% ethylenediamine tetraacetic acid (EDTA) when used in specific irrigant protocols. METHODS : Eighty single rooted maxillary incisors and canines were decoronated, standardized to a length of 15mm and prepared with rotary files upto protaper F3 size. Sodium hypochlorite was used as the initial rinse [1ml]. The samples were divided into experimental [Group III, IV, V, VI,VII, VIII and IX] (n=10) and control groups [ I-EDTA, II-Normal saline] (n=5) based on the type of final rinse solution [ 5ml] used ie., 2% C – low molecular, 1% C - Shrimp shell, 1% C – Crab shell, 4% C- oligosaccharide, 4% C- citrate, 10% CA, and 1% Acetic acid. Samples were dehydrated, split buccolingually, sputter coated and examined in Field Emission Scanning Electron microscope. RESULTS : Group VII presented the least amounts of smear among the experimental groups at the apical, middle and coronal one-thirds of the root canal with a mean value of 1.53 ±0.42 there was no statistically significant difference ( p > 0.05 ) CONCLUSION : The use of C- citrate and C-oligosaccharide as final rinse solution during bio-mechanical preparation seems promising.
