Background and
Objective: The
endodontic management of immature teeth with wide open apices has always posed
particular problems. A number of canal preparation and filling techniques have
been described such as apexification, surgery and retrograde filling, customized-cone,
and apical plug. The purpose of this study was to compare the sectional
technique microleakage in open apices with lateral compaction technique.   Materials and
Methods:
Twenty seven open apex canals and twenty seven close apex canals were used in
this study. Teeth were divided into two groups. In addition to 23 experimental
teeth in each group, there were 4 positive controls and 4 negative controls.
Group1 was filled with sectional warm gutta percha and group 2 was filled with
lateral condensation technique. The extent of dye penetration was determined
with stereomicroscope and by two independent observers. The data were obtained
and then statistically analyzed with t test.    Results: The mean microleakage )intra-canal dye penetration(
in group 1 (sectional)(penetration was 0.042) was not significantly different
versus group 2 (lateral) (penetration was 0.027).    Conclusion: This study suggests that sectional technique
is a suitable and non-surgical method for filling gutta-percha in open apex
teeth.
