The effect of post space preparation on the sealing ability of a root
canal filling is important because the sealer is crucial for preserving
the apical seal. The question of how, when, and how much of the
gutta-percha should be removed is a debate when preparing a post
space. This study is aimed to compare the effect of immediate versus
delayed post space preparation on the apical seal using AH Plus and
EndoREZ sealers. Forty four single rooted teeth were prepared using
the step-back technique and were obturated with combinations of
gutta-percha/AH Plus and gutta-percha/EndoREZ using the lateral
compaction technique. Four teeth were used as positive/negative
controls. After the teeth were divided randomly into six groups,
post spaces were prepared either immediately after filling or after
storage of the obturated teeth in saline at 37°C for one week. The
post space preparation procedure was performed using hot pluggers
or Gates Glidden drills leaving a 5 mm of root canal filling in the
apical part. Leakage was determined by a computerized fluidfiltration
device. Immediate and delayed post space preparation of
the gutta-percha/AH Plus groups had mean leakage values of 4.97
μl.cmH2O.min-1.10-4 and 4.94 μl.cmH2O.min-1.10-4, respectively.
The respective mean leakage values of immediate and delayed post
space preparation of the gutta-percha/EndoREZ groups were 4.97
μl.cmH2O.min-1.10-4 and 5.57 μl.cmH2O.min-1.10-4. The mean
leakage value obtained in the positive control group was 398.16
μl.cmH2O.min-1.10-4, whereas there was no fluid filtration in the
negative control group. Better sealing was achieved in the guttapercha/
AH Plus delayed group in comparison to the other groups.
Delayed post space preparation in the gutta-percha/EndoREZ group
showed the highest percentage of leakage.
