Aim:
To compare fluid movement (FM) along the coronal two-thirds of gutta percha/sealer root fillings placed by three different techniques.
Methodology:
Three groups consisting of the roots of mandibular incisors were instrumented and obturated by cold lateral compaction (LC), warm vertical compaction (VC) or the single-cone technique (SC), using RoekoSeal Automix (RSA) as the sealer. The apical 4 mm of each root filling was removed, and FM along the remaining 7 mm of the root filling was measured.
Results:
The VC group displayed more FM than the other two groups (P = 0.023). No significant difference in FM was found between the LC and SC groups (P = 0.629).
Conclusions:
The coronal two-thirds of the VC root fillings did not prevent FM when RSA sealer was used.
