Feasibility of transpedicular screw placement through the posterior arch of C1: A CT study in the Emirati population by Ivan James Prithishkumar, Dineshwary Suresh, Nerissa Naidoo, Rashid AlSharhan, Usama Al Bastaki, Jeyaseelan Lakshmanan, Baylis Vivek Joseph

“…Results: Mean intraosseous distance from screw entry point in the posterior arch to the anterior cortex of lateral mass following a straight course without any inclination was 28.0 mm in males and 29.0 mm in females, allowing a safe distance of 3.2 mm from the foramen transversarium laterally and 9.0 mm from the vertebral canal medially. A medial inclination of 18° in males and 14° in females allows for increased bone purchase. …”

Effect of ultrasonically-activated irrigation protocols used for regenerative endodontics on removal of dual species biofilm in a three-dimensionally printed tooth model: in vitro... by Saeed Mustafa, Marwa A. Meheissen, Sybel Moussa, Rania ElBackly

“…Dual-species biofilms (comprising Enterococcus faecalis and Streptococcus mutans) were cultivated in the root canal for a period of three weeks. Models with dentine specimens were randomly assigned into 5 groups according to the irrigation protocol; G1(dis H2O): infected root canals irrigated with distilled water to serve as controls; G2(1.5% NaOCl): 1.5% NaOCl for five minutes; G3(1.5% NaOCl + PUI): 1.5% NaOCl + passive ultrasonic irrigation (PUI) for 30 s; G4(3% NaOCl): 3% NaOCl for five minutes; G5(3% NaOCl + PUI): 3% NaOCl + PUI for 30 s. …”
