Background : The main aim of the present study is to qualify and quantify voids formation of root canals obturated with GuttaCore (GC) and experimental Hydroxyapatite polyethylene (HA/PE) as new carrier-based root canal fillings by using micro computed tomography scan.
Materials and methods: In the present study, eight straight single-rooted human permanent premolar teeth are selected and disinfected, then stored in distilled water.
The teeth decoronated leaving a root length of 12mm each.
The root canals instrumented by using crown down technique and the apical diameter of the root canal prepared to a size # 30 / 0.04 for achieving standardized measurements.
A 5mL of 17 % EDTA used to remove the smear layer followed by 5mL of 2.5 % NaOCl and rinsing with normal saline.
Then the shaped root canals were randomly subdivided into two groups of 4 teeth each according to the carrier-based obturation system use, GuttaCore or experimental HA/PE.
Afterwards, the obturated roots stored at 37°C with 100% humidity for 72 hours to allow for complete setting of the sealer.
Micro-CT was then scanned to quantify the voids within the root canal space.
The data were statistically analyzed by one-way ANOVA and post hoc comparison tests (α=0.05).
Results: The root canals obturated with both obturation systems, GuttaCore andexperimental HA/PE showed voids formation, particularly at the apical third of the root canal.
GC obturation showed a lower percentage of voids volume (1.54 %) than the experimental HA/PE obturation (2.3 %).
The void volume percentage in the GuttaCore system, however, was non-significantly different (P> 0.05) in comparison with the experimental PE/HA system.
Conclusions : GuttaCore and experimental HA/PE obturators exhibited voids formation within the entire root canal space.
The experimental HA/PE obturator is comparable to the GuttaCore obturator in terms of voids qualification
