Insights on the Dynamics and Toxicity of Nanoparticles in Environmental Matrices.

The manufacturing rate of nanoparticles (10-100 nm) is steadily increasing due to their extensive applications in the fabrication of nanoproducts related to pharmaceuticals, cosmetics, medical devices, paints and pigments, energy storage etc. An increase in research related to nanotechnology is also a cause for the production and disposal of nanomaterials at the lab scale. As a result, contamination of environmental matrices with nanoparticles becomes inevitable, and the understanding of the risk of nanoecotoxicology is getting larger attention.

Reattachment of fractured tooth fragment with fiber post: a case series with 1-year followup.

Coronal fractures of the anterior teeth are common sequelae of dental trauma. In case of complex fractures, where the fractured segment is available and there is close approximation of the segment to the remaining tooth, root canal treatment followed by reattachment of the fractured segment with fiber post reinforcement is a feasible option. The procedure is simple and economic and needs less chair-side time as compared to many conventional methods.

Surgical management of pyogenic discitis of lumbar region.

Study Design: Retrospective review of patients who had pyogenic discitis and were managed surgically.

Purpose: To analyze the bacteriology, pathology, management and outcome of pyogenic discitis of the lumbar region treated surgically.

Overview Of Literature: Surgical management of pyogenic discitis is still an infrequently used modality of treatment.
