Meniscal Roots: Current Concepts Review

Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony rootavulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stressesresulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment.These changes are detrimental to the articular cartilage and ult...

Fractured Roots

We report a clinical case of horizontal root fracture in the mandibular first premolar induced by a traffic accident. The fractured tooth spontaneously healed and diagnosed radiographically after 2 years. Fractured fragments were separated by a narrow radiolucent line and the edges were rounded, and healing of the tooth is likely to be related to interproximal connective tissue healing. Our cas...

Complex roots via real roots and square roots using Routh’s stability criterion

We present a method, based on the Routh stability criterion, for finding the complex roots of polynomials with real coefficients. As in Gauss’s 1815 proof of the Fundamental Theorem of Algebra, we reduce the problem to that of finding real roots and square roots of certain associated polynomials. Unlike Gauss’s proof, our method generates these associated polynomials in an algorithmic way.
