Apical microleakage evaluation of system B compared with cold lateral technique: In vitro study

Abstract

The aim of this study was to evaluate in vitro the apical sealing ability of cold lateral and system B root filling techniques using dye penetration. Eighty-six extracted single-rooted human teeth were prepared and randomly divided into two experimental groups to be obturated by cold lateral condensation (n = 33) and system B (n = 33). The remaining 20 teeth served as positive and negative controls. The roots were embedded for 72 h in methylene blue dye solution and sectioned transversely for dye penetration evaluation using stereomicroscope. The results of this study showed that cold lateral condensation leaked significantly more (P < 0.001) than system B technique.

Effect of Condensation Techniques on Fracture Resistance of Endodontically Treated Teeth Restored with Different Post Systems

“…All root canals used in this study were prepared by using the crown-down technique using ProTaper TM rotary system up to size F5 (finishing 5) for all specimens (24) .…”

“…The specimens received a final rinse with 17% EDTA solution in order to remove the smear layer then were rinsed with sterile water (10,14,24) .…”

“…The sealer used in obturation was AH plus that was used in several studies (24,25) . AH plus was used to avoid the effect of eugenol sealers on the retention of resin cemented posts due to the presence of eugenol on the canal walls appeared to have an adverse effect on post retention (25) .…”

Un approccio critico alle tecniche di otturazione canalare

“…In uno studio di Manal Farea et al 88 è stato valutato il sigillo apicale della tecnica laterale a freddo rispetto al System B utilizzando la tecnica di infiltrazione apicale di colorante. I risultati di questo studio in vitro hanno dimostrato che la condensazione laterale a freddo genera un'infiltrazione media di colorante statisticamente maggiore rispetto al System B.…”

Apical microleakage evaluation of system B and cold lateral compaction

“…This letter is in reference to the study by Farea, Masudi and Wan Bakar (1). In this study, the authors have used single rooted teeth with single canal to evaluate the apical leakage of teeth obturated using system B and cold lateral compaction technique.…”
