BACKGROUND To compare the amount of debris extruded apically by using conventional syringe, Endovac & Ultrasonic irrigation. MATERIALS & METHODS Thirty freshly extracted mandibular premolars were selected, working length was determined and mounted in a debris and collection apparatus. The canals were prepared. After each instrument change, 1 ml. of 3% sodium hypochlorite was used as irrigatio...

INTRODUCTION The purpose of this investigation was to compare the antimicrobial efficacy of root canal irrigation with the EndoVac (Discus Dental, Culver City, CA) to endodontic needle irrigation in the apical 5 mm of root canals infected with Enterococcus faecalis. METHODS Bilaterally matched, extracted human teeth were sterilized and inoculated with E. faecalis. Specimens in the EndoVac gro...

INTRODUCTION The purpose of this study was to compare the debridement efficacy of EndoVac irrigation versus conventional needle irrigation in vivo. METHODS Seven adult patients with a total of 22 matched pairs of single-canaled vital teeth with fully formed apices were recruited. Canals were instrumented to a master apical file size #40/.04 taper. One tooth from each matched pair was irrigate...

OBJECTIVE Immature teeth have a large apical opening and thin divergent or parallel dentinal walls; hence, with conventional needle irrigation there is a very high possibility of extrusion. This study was done to compare the apical extrusion of NaOCl in an immature root delivered using EndoVac and needle irrigation. MATERIALS AND METHODS Eighty freshly extracted maxillary central incisors wer...

AIM This study compared the efficacy of conventional, endovac and ultrasonic irrigation system for the removal of debris from root canal walls, using scanning electron microscopy (SEM) at cervical, middle and apical 3rd. MATERIALS AND METHODS A total of 30 freshly extracted human mandibular premolars with complete root formation were selected and divided into group 1 endovac, group 2 conventi...

INTRODUCTION The purpose of this study is to compare extrusion of irrigants delivered with a 27-G needle or the EndoVac system (Discus Dental, Culver City, CA) during instrumentation and final irrigation of teeth. METHODS Matched paired single canal teeth were divided into four sample groups and controls. The experimental groups were needle irrigation International Standards Organization (ISO...

The objective of this project was to evaluate the safety of various intracanal irrigation systems by measuring the apical extrusion of irrigant. Twenty-two single canal, extracted mature teeth were instrumented and secured through the lid of a scintillation vial to collect apically extruded irrigant. A precision syringe pump delivered controlled amounts of irrigant at a constant flow. The irrig...

INTRODUCTION The aim of this study was to compare the effect of the EndoVac irrigation system (SybronEndo, Orange, CA) and conventional endodontic needle irrigation on sealer penetration into dentinal tubules. METHODS Forty single-rooted, recently extracted human maxillary central incisors were randomly divided into 2 groups according to the irrigation technique used: conventional endodontic ...

The purpose of this in vivo study was to investigate the antimicrobial effectiveness of 6% sodium hypochlorite, when used with the conventional irrigation technique using a 30 gauge side-vented needle, the EndoVac TM System, and the ProUltra PiezoFlow TM Ultrasonic Irrigation Needle. It was hypothesized that both the EndoVac TM system and the PiezoFlow TM Ultrasonic Irrigation Needle would remo...

BACKGROUND This study aimed to compare the smear layer removing efficacy of the EndoActivator, EndoVac and Er:YAG laser in extracted mandibular premolars, at the apical, middle and coronal third of root canal, through scanning electron microscopy. MATERIAL AND METHODS 40 extracted mandibular premolars were decoronated to a standardized length of 12 mm. Specimens were shaped to ProTaper F4 siz...
