BACKGROUND Most often used intracanal medicament is calcium hydroxide (Ca(OH)2). Removal of Ca(OH)2 before obturation is mandatory. Different irrigation solutions and devices were tested in the previous study for this purpose. AIM The aim of this study was to evaluate the comparative efficacy of different irrigation techniques in removing intracanal medicament using cone-beam computed tomogra...

AIM: This study assessed the effectiveness of 5 different irrigant activation systems on canal cleanliness and removal smear layer from root canals. METHODS: A total 110 mandibular premolars with straight were assigned to five groups (n = 20): conventional needle irrigation, passive ultrasonic activation, sonic EndoActivator, negative apical pressure EndoVac (EV), or EDDY system, besides a cont...

This paper presents a system to estimate soil moisture through the reading of standard Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) tags that can be buried in the soil, allowing wireless moisture measurement without the need of using batteries in the field for long periods. In the proposed system, one or more passive EPC/GEN2 tags acts as sensors buried in the soil. ...

This study aimed to evaluate the efficacy of 5 irrigation protocols in removing calcium hydroxide simulated internal root resorption cavities. Eighteen extracted human teeth, upper anterior and uniradicular, were prepared up size 50. The teeth divided longitudinally, cavities made by acid demineralization using nitric acid. same sample was submitted five protocols. canals filled with Ultracal X...

AIM To compare the efficacy of the XP-endo finisher file (XP) (FKG Dentaire, La Chaux de Fonds, Switzerland) to that of passive ultrasonic irrigation (PUI) and conventional syringe and needle irrigation (SNI) in the removal of calcium hydroxide paste from an artificial standardized groove in the apical third of root canals. METHODOLOGY The root canals of 68 mandibular incisors with single ova...

Introduction: Wound debridement is considered essential in chronic wound management. Hypochlorous acid has been shown to be an effective agent in reducing wound bacterial counts in open wounds. Ultrasound-enabled wound debridement is an effective and efficient method of debridement. This study compared ultrasound irrigation with hypochlorous acid versus saline irrigation for wound debridement o...

This study evaluates the influence of root dentin treatment with NaOCl alone and combined with EDTA, with and without ultrasound activation, on the push-out bond strength (BS) of fiber-reinforced posts in weakened roots, cemented with RelyX or Panavia. The root canals of 42 maxillary canines were instrumented with Reciproc and 2.5% NaOCl. In the coronal 12mm of all canals, experimental weakenin...
