A Stereomicroscopic Evaluation of Four Endodontic Sealers Penetration into Artificial Lateral Canals Using Gutta-Percha Single Cone Obturation Technique
Background: Three-dimension obturation of whole root canals system complexity is so important step in root canal filling to isolate the remnant microorganisms from space and neutrinos and consequently is the success of such treatment
Aim of the study: Evaluation the filling capacity of artificial lateral canals after main canal single cone obturation with the following endodontic sealers:
TotalFill® BC, Gutta Flow bioseal, MTA fill apex and AH- plus forty single-rooted extracted lower premolars were instrumented up to size X2 (protaper Next, Dentsply) then generate three lateral canals in each mesial and distal aspects then randomly divided into four gropes (n=10) each group was obturated with single cone gutta-percha with deferent sealers G1: calcium silicate based sealer TotalFill® BC Sealer™(FKG), G2: ROEKO GuttaFlow® Bioseal (COLTEN), G3: MTA Fillapex(ANGELUS) and G4: AH Plus® (DENTSPLY)
The teeth will be demineralizing with week acid to evaluate the penetration of sealers into artificial lateral canals by stereomicroscope the significance of the difference of different means (quantitative data) were tested using Studentst-test for the difference between each two-independent means.
Result: For all ALCs of roots, the GUTTAFLOW BIOSEAL sealer had the highest mean penetration (94.83 ± 6.29) which was significantly higher than the penetration of AH-PLUS (p-value0.030), MTA-FILLAPEX (p-value 0.0001) and Totallfill BC (p-value0.001).
GUTTAFLOW BIOSEAL sealer In the coronal third had the highest mean penetration which was significantly higher than the penetration of Totallfill BC (p-value 0.049) and MTA-FILLAPEX (p-value 0.002) and not significant with AHPLUS (p-value 0.227).in the middle third also significantly higher than the penetration of Totallfill BC (p-value 0.017) and MTA-FILLAPEX (p-value 0.007) and not significant with AH-PLUS (p-value 0.278).the same in apical third which was significantly higher than the penetration of Totallfill BC (p-value 0.0001) and MTA-FILLAPEX (p-value 0.003) and not significant with AH-PLUS (p-value 0.054).
