Comminuted middle third orbito-zygomatic complex fracture leading to blindness due to unanticipated tyre rim explosion during service - A rare case.

An explosion is caused by conversion of solid, liquid into gas with resultant energy release. Blast injuries of large tyres are similar to injuries resulting from landmine explosions. Most of the patients were polytraumatised, initial evaluation and management should follow ATLS.

A Self-Retaining Lingual Flap Guarding Device During Surgical Removal of Impacted Mandibular Third Molar.

Introduction: Lingual nerve damage is one of the common complications following mandibular third molar surgery. On considering the impact of lingual nerve damage on the patient's quality of life, it is necessary to exercise caution to minimize its occurrence.

Material And Methods: Although many lingual retractors are available, in this article we describe an indigenously designed lingual retractor for use in mandibular third molar surgery.

Colorimetric and fluorimetric response of salicylaldehyde dithiosemicarbazone towards fluoride, cyanide and copper ions: Spectroscopic and TD-DFT studies.

The sensing mechanism of salicylaldehyde phenyldithiosemicarbazone (SDTSC) chemosensor has been investigated by spectroscopic and TD-DFT methods. The SDTSC shows colourimetric and spectral changes towards fluoride, cyanide and copper ions. The interaction between SDTSC with fluoride, cyanide and copper ions was examined through their absorption and fluorescence behaviour, and found that SDTSC has more sensing ability towards Cu ion than CN and F ions.
