Numerical models commonly account for elastic inhomogeneity in cortical bone using power-law scaling relationships with various measures of tissue density, but limited experimental data exists for anatomic variation in elastic anisotropy. A recent study revealed anatomic variation in the magnitude and anisotropy of elastic constants along the entire femoral diaphysis of a single human femur (Es...

C-shaped canal is one of the most difficult situations with which dentist confronted during endodontic treatment teeth. Recognition unusual variation in configuration critical because it has been established that root a single tapering and apical foramen exception rather than rule. The early recognition these configurations facilitates cleaning, shaping obturation system. “C” configuration, an ...

1209 November 2013 T transversus abdominis (TA) plane regional anesthesia block is a well-described and effective method for reducing pain from lower abdominal surgeries. Successful ultrasound-guided TA plane block is dependent on correct recognition of muscle borders within the anterolateral abdominal wall.1 This wall is composed of three distinct muscle layers from the external oblique (eO), ...
