Objective:
This study compared the dentinal tubule penetration of NeoSEALER Flo bioceramic sealer using single cone and cold lateral compaction obturation techniques.
Methods:
Eighteen extracted single-rooted mandibular premolars were randomly divided into two groups (n=9) according to the obturation technique used. The maximum penetration depth in microns, percentage of penetration depth, and percentage of penetration area of the NeoSEALER Flo bioceramic sealer were assessed using confocal laser scanning microscopy at different root levels; coronal, middle, and apical. Data was statistically analyzed using Kruskal-Wallis's test followed by Dunn's post hoc test with Bonferroni correction and Friedman's test followed by Nemenyi post hoc test with the significance level set at p<0.05.
Results:
The single cone obturation technique has shown a statistically significantly higher percentage area of NeoSEALER Flo penetration than the lateral compaction technique at the coronal root level only. Otherwise, both obturation techniques have shown no statistically significant differences in NeoSEALER Flo penetration distance, percentage of penetration distance, and percentage of area penetration at the middle and apical root levels.
Conclusion:
The single cone obturation technique can be used with bioceramic sealers yielding comparable results to the cold lateral compaction technique. (EEJ-2024-12-192).
