pH Change Following Smear Layer Removal and Final Rinse with 95% Ethyl Alcohol Using Calcium Hydroxide Medicament or BC Sealer
… were sealed at coronal and apical ends using two layers of sticky wax and were placed in a 4mL lab vial containing 2mL of sterile saline. pH was measured days 0,1,2,4,7,9,12,16,22,28. Tooth roots were sectioned and remaining dentin thickness (RDT) was measured to correlate RDT and pH values. A …

In Vitro Evaluation of the Biolase ER,CR:YSGG Side-Firing Tip For Bacterial Biofilm Reduction and Smear Layer Removal in Root-End Cavity Preparation
… associated with residual bacterial biofilm and smear layer that may remain after conventional chemomechanical debridement and ultrasonic root-end preparation, contributing to post-treatment apical periodontitis and compromising root-end surface cleanliness. The objective of this in vitro study …

Vergleich der Wirkung unterschiedlicher endodontischer Spül- und Reinigungssysteme (Handspülung, Ultraschall, EndoActivator®, CanalBrush®) auf die Sauberkeit präparierter Wurzelkanalwände
… Spülung zur Entfernung von Debris und Smear Layer untersucht. Achtzig gekrümmte Wurzelkanäle in extrahierten Unterkiefermolaren wurden unter Verwendung von NaOCl ( 3%) zur Spülung maschinell bis zur Größe .02/40 präpariert. Es wurden die dynamische Handspülung, die …

An in-vitro SEM study comparing the debridement efficacy of the EndoVac® system versus the Canal CleanMax® following hand-rotary istrumentation
… according to relative amount of debris and/or smear layer present, as well as relative number of patent dentinal tubules. These scores were statistically analyzed using a Krustal-Wallis test and Wilcoxon Rank Sum tests to determine differences between groups. The coronal aspect of root canal …

Effects of tooth quality, tooth structure, and cement mixing ratios on dental adhesion
… and lower chemical adhesion when the smear layer covers the dentin. Mixed failure modes were detected during dentin debonding while cohesive failure within the cement were observed during enamel debonding indicating that enamel bonded better to the cement than dentin did. Improper …

The Effect of Root Canal Cleansing on the Retention of Glass Fiber-reinforced Posts
… such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass fiber-reinforced posts, when …

Effect of Diamond Bur and Root Canal Irrigants on Retention of Fiber Posts
… such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass fiber-reinforced posts, when a …

Shear Strengths of Three "One-Step" Self-Etching Dental Bonding Agents
… to expose superficial dentin. A standardized smear layer was created by polishing the surfaces with wet 600-grit silicon carbide paper. Each adhesive system was placed on the specimen surface according to the manufacturers' instructions. The specimen then was mounted onto a standardized jig …
