Locking plates for distal femur fractures does an increased working length improve healing?
… these problems longer plates and an increased working length have been proposed to reduce construct rigidity. The purpose of our study is to investigate whether an increased working length translates into improved healing.

An in vitro comparison of working length accuracy between a digital system and conventional film when vertical angulation of the object is variable
Accurate determination of working length during endodontic therapy is critical in achieving a predictable and successful outcome. Working length is determined by the use of electronic apex locators, tactile perception, knowledge of average tooth lengths and dental radiography. Due to the increasing …

An in-vitro comparison of working length determination between a digital system and conventional film when source-film/sensor distance and exposure time are modified
Accurate determination of working length during endodontic therapy is a crucial step in achieving a predictable outcome. This is determined by the use of electronic apex locators, tactile perception, and knowledge of average tooth lengths and/or dental radiography whether digital or conventional is …

Retreatability of root canals obturated using a bioceramic sealer and gutta percha
… were to determine the possibility of achieving working length and apical patency when obturation is done with the master GP placed at working length and when it is short by 3mm. The time it took to achieve these parameters when it was possible to achieve them was also determined. The role of XP …

Auswirkung der Schwingstrecke und des Platten-Winkels einer Doppelplatten-Osteosynthese in einem ovinen Tibia-Defektmodell - eine Finite-Elemente-Analyse
… torsion at 25 Nm. The models differed by plate length, plate-to-bone distance, number of screws and plate working length. Results Single-plate osteosynthesis in a CSD resulted in implant failure within the first loading cycles. In the DPO, the 120° configuration resulted in an 12.9 times higher …

In Vitro Accuracy of the E-PEX Electronic Apex Locator Compared to the Root ZX II in the Presence of Various Irrigation Solutions
… (NSRCT). This reference point determines the working length, and is commonly calculated with the aid of an electronic apex locator (EAL), which accurately identifies the apical foramen which in turn determines the working length. Throughout endodontic procedures, clinicians utilize a range of …

In Vitro Precision of the E-PEX Electronic Apex Locator Compared to the Root ZX II in Various Embedding Media
… root canal treatment (NSRCT) is determining the working length of the canal which indicates the end point of root canal preparation and obturation. The development of the Electronic Apex Locator (EAL) has helped the clinician to determine the location of the apical foramen, and hence the working …

Apical and radial pH diffusion through root dentin from five modern intracanal medicaments: a twelve-week evaluation of alkaline dynamics
… alkalinization. Complete medicament delivery to working length is critical, as passive diffusion does not compensate for incomplete placement.

Spectrophotometric determination of irrigant extrusion using passive ultrasonic irragation, endoactivator or conventional irrigation
… teeth were decoronated to leave 15 mm of root length for each tooth. Cleaning and shaping of teeth was completed using hand and rotary instrumentation (ProTaper[Dentsply]) to apical file size #40/0.04 taper. Root ends were sealed (not apex) and placed into a microcentrifuge tube with the …

Development of a novel mobile flexible hysteroscopy system for outpatient procedures without general anaesthesia
… single-handedly. It was verified to have a 260mm working length, 4.2mm diameter scope with a 236° bending range, 79 minutes of continuous usage, and the disposable sheath could isolate the system while fully submerged and supply saline solution at over 200 mmHg pressure. The trial results showed …
