Dynamic shear properties of porcine periodontal ligament. (a) Complex modulus $\text{[math]}$ , storage modulus $\text{[math]}$ , and loss modulus $\text{[math]}$ as a function of frequency. (b) Tangent $\text{[math]}$ as a function of frequency. Data were obtained from incisor (white circle) and molar (black circle) periodontal ligaments.
