A new SWEEPS (Shock Wave Enhanced Emission Photoacoustic Streaming) modality for Er:YAG laser is presented, developed especially to improve the cleaning and disinfecting efficacy of laser-assisted endodontic procedures. Typically, shock waves are not emitted during laser-assisted irrigation of spatially confined root canals. However, by using the new SWEEPS modality, an acceleration of the coll...

As indicated by standards of modern dentistry, the essence endodontic treatment is chemo-mechanical disinfection root canal system. The vital element this process irrigation canals with designated solutions as well activating them. This review article summarizes various techniques activation irrigants for such manual activation, thermal, pressure, sonic, ultrasonic, and laser in order to compar...

The purposes of this study were to investigate the reliability and efficiency of a new evaluation method for resin bonding to root canal dentin, which measures both marginal adaptation and shear bond strength simultaneously, and to determine the effects of root canal irrigants on resin bonding. A wet bonding system (Single Bond) and a self-etching primer system (Clearfil Mega Bond) were employe...

This study evaluated the protocols of sonic and vacuum irrigation regarding the capacity of debris removal from root canal systems. Canal preparations were carried out on 30 mandibular first molars using the ProTaper Universal System. Teeth were divided into two experimental groups (n=15): Group 1: sonic irrigation and Group 2: vacuum irrigation protocol. Subsequently, the mesial roots were sec...

BACKGROUND Different studies have used different tests to evaluate bond strength of resin cements to root dentin. In this in vitrostudy, three different tests were used to evaluate the bond strength of two resin cements to root dentin using two root dentin irrigation protocols. MATERIAL AND METHODS Ninety-six intact single-rooted teeth were selected for this study. Forty-eight teeth, with a r...

Sodium hypochlorite was inadvertently injected into the maxillary sinus during root canal treatment of the right maxillary first molar. Sterile water irrigation of the sinus was effected through the palatal canal. The expected sequelae of pain, significant edema, and hemorrhage were not experienced.

As important passive flow control methods, dimples and protrusions have been successfully implemented via geometric modifications to manipulate flow fields to get a desired flow parameters enhancement. In this research, two novel needles were proposed based on a prototype by means of the dimple and protrusion, and flow patterns within a root canal during final irrigation with these needles were...

statement of problem: it is necessary to use irrigation solutions during cleaning and shaping of root canals to efficiently reduce the number of micro organisms. sodium hypochlorite is used as an effective antibacterial endodontic irrigants. however, the extract of pennyroyal plant has also shown anti-bacterial characteristics comparable with antibacterial drugs. objectives: to compare the anti...

The field of endodontics is devoted to the study and treatment of tissues inside (endo) the tooth (dontia). When a nerve within a tooth becomes necrotic andor infected, socalled root canal therapy might be considered. In this case, a dental practitioner cleans and widens the inner root canal system by chemical irrigation and mechanical instrumentation with respect to the original canal morpholo...

INTRODUCTION Due to the complex anatomy of the root canal system and high surface tension of common root canal irrigants (RCI), conducting an investigation on RCIs containing surfactants is a priority. The aim of this in vitro study was to verify the antibacterial potential of RCI with low surface tension in root canals infected with Enterococcus faecalis (E. faecalis). METHODS AND MATERIALS ...
