Abstract



Objective: To compare the effect of Ethylenediamine tetraacetic acid (EDTA) and
calcium hydroxide [Ca(OH)2] in the removal of root canal filling
material during retreatment procedure.



Methodology: Eighty extracted, single-rooted human teeth were used. Root canals were shaped
with a crown-down technique using Ni-Ti rotary instruments (ProTaper, Dentsply
Maillefer, Switzerland) and filled with a cold lateral condensation method. AH
Plus was used as a sealer. After filling, the teeth were divided into 4 groups
and root fillings were removed by ProTaper Universal rotary retreatment
system. In each group different irrigation and disinfection protocols were
followed; Group I. Sodium hypochlorite (5.25%) + EDTA
(17%-1 min.) Group II. Sodium hypochlorite (5.25%) Group III. Sodium hypochlorite (5.25%) + Ca (OH)2 Group IV. Sodium hypochlorite (5.25%) + Ca(OH)2 + EDTA (17%-1 min.). Irrigation with
17% EDTA was performed only before D3-Retreatment instrumentation in
all groups. AutoCAD system was used to detect the amount of residual root
canal filling material. The results were statistically analyzed by SPSS
(Statistical Package for Social Sciences) for Windows 15.0, one way ANOVA and
Tukey’s HSD tests. The significance was evaluated at the level of p<0.05.



Results: The amount of the remnant
filling material in the root canals retreated in Group I was less than the
amount of the material in Group II (p<0.01) and Group III (p<0.05). There
was no significant difference observed between the other groups in terms of the
quantity of the remnant root canal filling materials (p>0.05).



Conclusions: Irrigating the canals with EDTA enhanced the removal of root canal
filling during retreatment. However, disinfecting the canals with Ca(OH)2 had no effect in the removal of
filling material.



Keywords: Retreatment, Sodium
Hypochlorite, Ethylenediamine tetraacetic acid, calcium hydroxide.
