مقارنة مخبرية لجودة الختم الذروي لمادة GuttaFlow مع مادة AH Plus لدى حشو القناة بتقنيتين مختلفتين

Abstract EN

Background & Objective: A good apical sealing is considered the key of the successful endodontic treatments.

The aim of this study was to compare the apical seal of GuttaFlow and AH Plus using single cone and lateral condensation technique.

Material& methods: Forty human single canal teeth were prepared using the crown-down technique and irrigated with 1.3% NaOCl & MTAD as a final irrigation.

A total of 40 samples were divided into four groups (n=10) according to root filling Materials and obturation technique: G1.

GuttaFlow + single cone, G2.

GuttaFlow + lateral compaction gutta-percha, G3.

AH Plus + single cone and G4.

AH Plus + lateral compaction gutta-percha.

The teeth were then placed in 2% methylene blue solution, sectioned longitudinally and examined by a stereomicroscope (20×magnification) to evaluate of the linear dye penetration.

ANOVA, Bonferroni and T student test were used for statical analyses.(P<0.05).

Results: The statical analysis showed that GuttaFlow achieved better apical seal than AH Plus when used with lateral condensation significantly (p=0.008), and no significant differences with single cone technique (p=1.000) .

Single cone technique provided better apical seal when AH Plus was used as a sealer when compared to lateral condensation technique (p=0.036).

While no significant differences were found in apical seal of Guttaflow between lateral condensation and single cone technique ( p=0.420).

Conclusion: GuttaFlow showed a better apical seal and the obturation technique did not affect on its apical seal.

Whereas, AH Plus sealer with single cone had better apical seal than lateral condensation.
