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., zygomaticus minor, levator anguli, orbicularis oris, and levator labii superioris). This technique includes removing a strip of mucosa from the maxillary buccal vestibule, creating a partial-thickness flap between mucogingival junction and upper lip musculature, and suturing the lip mucosa with mucogingival junction, resulting in a narrow vestibule and restricted muscle pull, thereby reducing gingival display.

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. TB and periodontitis are the two distinct disease processes. But environmental and biological factors play a key role in etiopathogenesis of both the diseases. These factors alter tissue microenvironment leading to cascade of untoward events. AIM: To assess and compare the periodontal status of TB patients with that of non-TB subjects. MATERIALS AND METHODS: 50 subjects were recruited and divided into 2 groups. Group A consisted of subjects suffering from TB serving as Test group while group B included non-TB subjects serving as Control group. STATISTICAL ANALYSIS: Unpaired t-test was used. RESULTS AND CONCLUSION: Statistically significant difference in probing pocket depth and bleeding on probing was found between groups A and B, with the difference being higher in group A subjects, thus concluding that periodontal status might be linked with TB.
