Dento-alveolar and facial injury caused by air gun pellets.
UNLABELLED Recent changes in the law concerning air gun ownership have made air guns a topical subject and many have called for even tighter restrictions. A case of accidental injury during play with an air rifle is described. It highlights the dental and soft tissue damage that can arise from an injury from such a 'toy' and outlines its subsequent management. CLINICAL RELEVANCE This case hig...
متن کاملMinimal velocities necessary for perforation of skin by air gun pellets and bullets.
A series of tests were conducted to determine the velocities necessary for lead air gun pellets (calibers .177 and .22) and caliber .38 lead bullets to perforate skin. Human lower extremities were used. Caliber .177 air gun pellets weighing 8.25 grains required a minimum velocity of 101 m/s (331 ft/s) to perforate skin. The energy per area of presentation ratio E/a was 1:86 m X kg/cm2. Caliber ...
متن کاملnumerical simulation and operation comparison of two sizes of air gun pellets with 4.5 and 5.5 mm calibers
in this paper the numerical simulation and operation comparison of two sizes of air gun pellets with 4.5 and 5.5 mm calibers is performed. these pellets affected by drag force and are encountered to continuous velocity variations and experience an unsteady flow. in order to solve this problem numerically, the navier- stokes equations in an unsteady compressible turbulent flow with the dynamical...
متن کاملMissile-related Lead Exposure and Blood Pressure in Patients with Retained Pellets in the Craniomaxillofacial Region
Background: Environmental and occupational lead exposures are known to cause an elevated blood pressure but can this concept be applied to missile-related lead exposure? Methods: We implemented a controlled, cohort study design to examine study samples with long-standing missiles in craniomaxillofacial region using atomic absorption spectrophotometry and standard sphygmomanometry to measure ...
متن کاملThe best treatment can be no treatment: retained retro-orbital air gun pellet following attempted suicide.
1 of 3 DESCRIPTION A 35-year-old man presented after shooting himself in the right orbit with an air rifl e following an attempted suicide. His visual acuity was 6/5 in the right eye and 6/6 in the left. An entry wound was noted on the medial aspect of the upper lid. The anterior segment was otherwise unremarkable. Examination of the posterior segment revealed no signifi cant abnormalities. The...
