OCE quantification of Poisson's ratio through 2D speckle tracking.

We describe a real-time 2D motion tracking method based on speckle analysis. We implemented this method in real-time using graphic s processing unit (GPU). The capability to track both axial and lateral motions will enable more comprehensive characterization of tissue mechanical properties including Poisson's ratio.

Lip Repositioning: A Boon in Smile Enhancement.

This clinical report describes the successful use of lip repositioning technique for the reduction of excessive gingival display. The lip repositioning technique was performed with the main objective of reducing gummy smile by limiting the retraction of elevator muscles (e.g.

Periodontal status of tuberculosis patients - Is there a two-way link?

Background: The influence of systemic disorders on periodontal tissues is well established. Amongst various chronic debilitating diseases, tuberculosis (TB) is one of the major health problems in most developing countries. Although it has a definite affinity for the lungs, it can affect any part of the body including the oral cavity.
