The elimination of necrotic and inflamed pulp tissue, dentin debris, microorganisms is essential for the success endodontic treatment. However, root canal’s complexity has led to incomplete cleaning disinfection. This study aims compare efficacy penetrability three different irrigation activating techniques apical third canal. Sixty sound single-rooted human mandibular premolars are prepared wi...

OBJECTIVES To investigate differences in surgical time, the distance the surgical instrument travelled and number of movements required to complete manual phacoemulsification cataract surgery versus femtosecond laser cataract surgery. DESIGN Non-randomised comparative case series. SETTING Single surgery site, Moorfields Eye Hospital, UK. PARTICIPANTS 40 cataract surgeries of 40 patients. ...

Femtosecond laser-assisted cataract surgery has grown in popularity among ophthalmologists as a novel technique with the potential to reduce phacoemulsification energy requirements.1,2 However, early adoption of femtosecond laser-assisted cataract surgery by experienced cataract surgeons has been associated with a significant learning curve.3 Roberts et al. reported higher complication rates in...

Background To identify areas for improvement, the National Health Service in England mandates the review of case reports of patients who have died, which should be translated into improved care for other patients. Case report A 49-year-old Caucasian man sustained C-7 tetraplegia in a motorcycle accident in 1992. In 2009, he developed seizures and collapsed in the lavatory on a number of occas...

The dependency of surfaceor groundwater flows and aquifer hydraulic properties on dewateringinduced layer deformation is not available in the USGS's groundwater model MODFLOW. A new integrated hydrologic model, MODFLOW-OWHM, formulates this dependency by coupling mesh deformation with aquifer transmissivity and storage and by linking land subsidence/uplift with deformationdependent flows that a...

Carrot samples from field research studies of irrigation, fertility, and variety trials must be cleaned prior to weighing and grading. Soil and other foreign materials must be removed, especially for medium– and heavy–textured soils in which a preharvest irrigation is used to loosen the soil prior to hand harvesting. The objective of this project was to develop a low–cost mechanical carrot wash...

Although the term precision irrigation is now quite widely used, often to mean drip irrigation, there is no commonly accepted definition or conceptualisation of the term, and no cohesive framework to guide research, development or adoption. This paper is reporting on a review of precision irrigation funded by NPSI. This review is considering the role of current irrigation application technologi...

purpose: to present a case of traumatic bilateral eyelid lymphedema. case report: an 18-year old male presented with severe bilateral eye lid lymphedema with a history of severe craniofacial trauma three month ago and neurosurgical procedure. he had lost vision in his left eye because of sever globe injury. his lymphedema was attributed to wide surgical incision scar. the patient underwent manu...

BACKGROUND The need for reoperation or wound infection treatments between pulsatile and gravity irrigation are statistically equivalent, however, it is unclear which method maximizes operative efficiency and expeditious irrigation. In this study we set out to determine the differences in irrigation rate between these various treatment methods. METHODS This was an ex-vivo experimental laborato...
