Abstract Background Given the favorable antimicrobial properties of zinc oxide (ZnONPs), standard silver (AgNPs), and imidazolium-based (Im-AgNPs) nanoparticles, this study aimed to evaluate their influence on microhardness root canal dentin. Methods In experimental study, 40 mandibular premolars were decoronated at cementoenamel junction longitudinally sectioned into halves create 80 specimens...

Adequate removal of the previous filling material may be pivotal to a favorable outcome root canal retreatment teeth with post-treatment periodontitis in order permit access irrigants and medicaments persistent bacteria. However, even recent technological advances, including introduction specially designed instruments, no technique has been shown predictably promote complete removal. Supplement...

Endodontic irrigating solutions may interact chemically with one another. This is important, because even when solutions are not admixed, they will come into contact with one another during an alternating irrigation technique, forming unwanted by-products, which may be toxic or irritant. Mixing or alternating irrigants can also reduce their ability to clean and disinfect the root canal system o...

The purpose of this study was to determine the minimum instrumentation size required for the effective penetration of irrigants and elimination of debris and smear layer from the apical third of the root canals. The mesiobuccal canals of 40 freshly extracted human mandibular first molar teeth were instrumented using the crown-down technique. The teeth were divided into four test groups accordin...

OBJECTIVE This clinical study was undertaken to compare the effectiveness of 2.5% sodium hypochlorite (NaOCl) and 0.12% chlorhexidine digluconate as irrigants in reducing the cultivable bacterial populations in infected root canals of teeth with apical periodontitis. STUDY DESIGN According to stringent inclusion/exclusion criteria, 32 teeth with primary intraradicular infections and chronic a...

Irrigation is probably the most underrated procedure in Endodontic therapy. While most articles or presentations spend a great deal of time on shaping procedures, not much emphasis is given for irrigation. This has led to a great deal of confusion on the type of irrigant, the protocol and the method of use. The purpose of this article is to discuss root canal irrigants, irrigation techniques an...
