Abstract
Obturation materials with superior adaptation and sealing capacity are crucial
for root canal treatment success.
Objective: To compare adaptation and tubular penetration depth of three different sealers
(Ceraseal, AH Plus and Endofill) with single cone obturation technique using scanning
electron microscope (SEM).
Materials and Methods: Thirty-six extracted single canaled mandibular premolar teeth were
decoronated and prepared using ProTaper Universal rotary files till F3. Teeth were randomly
divided into three groups according to sealer type used: group I: Ceraseal (Bioceramic
sealer), group II: AH Plus (Resin sealer), group III: Endofill (Zinc Oxide Eugenol sealer).
All roots were obturated with a single F3 cone with one of the assigned sealers. Teeth were
sectioned into three thirds horizontally and analyzed for sealer adaptation and penetration
using SEM.
Results: Regarding sealer adaptation, roots filled with AH Plus showed better adaptation (less
mean gap sizes) than other sealers in the three canal thirds and the least mean gap sizes were
recorded in the apical third in all groups. Along the complete canal length, a significant
difference was found between AH Plus group and other groups (P <0.0001). Regarding
tubular penetration depth, Ceraseal showed greater mean penetration depth in the middle and
apical thirds than other sealers. However, along complete canal length, no significant
difference was found between Ceraseal and AH Plus groups with a significant difference
noted between both groups and Endofill group (P <0.0001).
Conclusion: Single cone obturation in mandibular first premolar teeth with AH Plus and Ceraseal
could result in significant better adaptation and tubular penetration than Endofill sealer.
