Automated perimetry is used for the assessment of visual function in a variety of ophthalmic and neurologic diseases. We report development and clinical testing of a compact, head-mounted, and eye-tracking perimeter (VirtualEye) that provides a more comfortable test environment than the standard instrumentation. VirtualEye performs the equivalent of a full threshold 24-2 visual field in two mod...

BACKGROUND Electronic apex locators (EALs) are modern devices used to determine the working length during root canal preparation. The newest endodontic motors provide an integrated EAL with auto-stop function to prevent instrumentation beyond the predefined working length during rotary root canal preparation. The aim of this study was to compare the accuracy of the auto-stop function of the VDW...

Microsurgery comprises a variety of surgical procedures such as neurovascular anastomoses, performed under optical magnification and with fine instrumentation. While refinements have been made since its advent in the 1960s, robotics offers the potential for major technological advancement. Endoscopic telemicrosurgery is minimally invasive, robotically-assisted microsurgery. This technique remov...

Current flow cytometry (FCM) reagents and instrumentation allow for the measurement of an unprecedented number of parameters for any given cell within a homogenous or heterogeneous population. While this provides a great deal of power for hypothesis testing, it also generates a vast amount of data, which is typically analyzed manually through a processing called "gating." For large experiments,...

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...

Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosis predisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concern before performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often been considered a contraindication for spinal surgery, while i...

Background: The technical quality of root canal treatment (RCT) may impact on the outcome. education received during undergraduate school be linked to provided in general dental practice.
 Objective: To compare RCT where rotary or manual step-back preparatory technique was employed an clinic Turkey. Additionally, present study aimed radiographically commonly seen complications both instrum...

introduction: the aim of this in vitro study was to evaluate the effects of establishing glide path on the centering ability and preparation time of two single-file reciprocating systems in mesial root canals of mandibular molars. methods and materials: sixty extracted mandibular molars with curvatures of 25-39 degrees and separate foramina for the mesiobuccal and mesiolingual canals, were divi...
