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...

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...

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...

OBJECTIVE To gather information on the materials and methods employed in root canal treatment by dentists in Turkey. METHODS A questionnaire was distributed to 1,527 dentists who attended the Turkish Dental Association Congress. Respondents were asked to choose one or more suitable answers for the questions. Data was gathered for demographic and professional information regarding stages, mate...

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 ...

BACKGROUND Cleaning and shaping of root canal system requires various irrigating solutions. The question is whether the presence of irrigation solution alters working length determination using apex locators. The purpose of this study was to compare the accuracy of Root ZX and i-Root apex locator for determining working length in the presence of different irrigating solution. MATERIALS AND ME...
