Introduction: This in vitro study was designed to compare the antimicrobial effects of PIPS® laser activation of irrigant against established 3-week bacterial biofilms to traditional needle irrigation in root canal therapy. Methods: Twenty-four extracted human teeth of one common canal configuration (Vertucci Type II) were endodontically cleaned and shaped using two different preparations (flar...

OBJECTIVE To compare the disinfecting efficacy of the sodium hypochlorite irrigation by root canal preparation with stainless steel hand files, taper 0.02 and nickel-titanium Mtwo files with taper 0.04-0.06. STUDY DESIGN 40 extracted human teeth were sterilized, and then inoculated with Enterococcus faecalis (ATCC 29212). After 6 day incubation time the root canals were prepared by hand with ...

Root canal instrumentation produces a layer of organic and inorganic material called the smear layer that may also contain bacteria and their by-products. It can prevent the penetration of intracanal medicaments into dentinal tubules and influence the adaptation of filling materials to canal walls. This article provides an overview of the smear layer, focusing on its relevance to endodontics. T...

in order to achieve a long-lasting effect, one of the main goals in root canal treatment is to eliminate the endodontic bacteria. conventional chemomechanical debridement is considered as the basic treatment in root canal therapy, but adjunctive techniques such as antimicrobial photodynamic therapy (apdt) can also be helpful. the aim of this study was to evaluate reports in the scientific liter...

AIM To examine the clinical and radiographic appearance of teeth with immature apices that were treated by single step procedure using mineral trioxide aggregate (MTA). SUMMARY Creation of a physiological hard tissue barrier with calcium hydroxide in a nonvital tooth although quite predictable has certain limitations, such as the very long duration of the treatment spread over multiple visits...

Root canal disinfection is one of the main factors governing success of endodontic therapy. Antimicrobial photodynamic therapy (aPDT) is presented as a promising antimicrobial therapy that can eliminate microbiota present in infected root canal systems. In this study, a series of experiments investigated the effects of aPDT on cell viability and biofilm degradation ability of endopathogenic mic...

introduction: this study evaluated and compared colony forming units (cfus) and minimum inhibitory concentrations (mics) of calcium hydroxide and propolis as intracanal medicaments. materials and methods: eighty human single-root and caries-free teeth were selected and divided into five groups. crowns were removed. root canals were then prepared in a step-back manner. the samples were then inoc...
