Endofill and EZ-Fill obturating sealers were evaluated and compared for coronal micro leakage in the presence of additional coronal sealing by either Bond1 SF or KN100 as intra-orifice plugs. One hundred and two human single-canalled premolars were decoronated and instrumented, then divided into two groups: Group I (Endofill), Group II (Ez-fill) were used as obturating sealers.
Each group was subdivided into 3 sub-groups: Bond 1 SF in subgroup a, KN100 in subgroup b were placed as intra-orifice plugs, while subgroup C was left free of any coronal barriers, Samples were submerged in Methylene blue dye and leakage was measured after 1 day, 1 week and 1 month. Twelve samples representing all subgroups were examined by SEM. Ez-Fill cement demonstrated significantly better coronal sealing ability compared to Endofill (p = 0.028). The addition of Bond 1 SF or KN100 as intra orifice plugs had no effect on improving the coronal seal. Bond 1 SF however, showed less coronal leakage values than KN100 (p = 0.096) at the end of the study period.
