Can the intra-examiner variability of Little's Irregularity Index be improved using 3D digital models of study casts?
The use of 3D digital models can improve the reliability of LII measurements by reducing the subjectivity associated with choosing the anatomic tooth contact points and the awkwardness of measuring the contact point displacements on study casts using a cumbersome calliper technique.
Prehospital hypotension is a strong predictor of the need for an emergent, therapeutic operation in trauma patients with normal SBP on arrival to the ED.
