A new device for irrigation, which presents hydrodynamic activation based on the pressure-suction technology, has recently been introduced to the market: the RinsEndo system. This study compared the efficacy of the RinsEndo system and conventional (manual-dynamic) irrigation in the removal of debris from the root canal walls, using scanning electron microscopy (SEM). Twenty mandibular premolars...

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...

BACKGROUND The aim of this study was to compare manual needle irrigation (MNI), RinsEndo (RE), and passive ultrasonic irrigation (PUI), and assess the effect of gravity on extrusion from the apex in vitro. MATERIAL AND METHODS The distobuccal roots of molars were used and the canals were instrumented up to F2. Teeth were mounted on models, which permitted visualization and manipulation of the...

background: different techniques have been introduced to improve removing the calcium hydroxide intra-canal dressing. the purpose of this study was to compare the effi ciency of passive ultrasonic irrigation (pui) and rinsendo system in the removal of calcium hydroxide from root canal system. materials and methods: access cavities were prepared in 50 single-rooted anterior teeth. cleaning and s...

The success of the endodontic treatment depends on the removal of vital or necrotic pulp tissue and minimizing the amount of pathological debris from the complex root canal system. Root canal irrigation seems to be undeniably important during biomechanical preparation, particularly because, during mechanical instrumentation, approximately 35-40% of the root canal surface remained unchanged (1)....
