Research has yet to find any evidence of this treatment being effective. Likely the raw meat was used when ice packs were not yet commercially available and meat was stored in iceboxes instead of in a protective gas. While cold but not freezing, meat is more gentle to the skin than ice and will not damage the surface of the skin as the skin temperature cannot go below freezing even in extreme cases. Meat is also soft and comes easier into contact with the skin than blocks of ice that were available. Associated conditions
Eye injury and head trauma may also coincide with a black eye. Some common signs of a more serious injury may include:

Double vision
Loss of sight and/or fuzzy vision could occur
Loss of consciousness
Inability to move the eye or large swelling around the eye
Blood or clear fluid from the nose or the ears
Blood on the surface of the eye itself or cuts on the eye itself
Persistent headache or migraine

Periapical periodontitis or apical periodontitis (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root, most commonly caused by bacterial invasion of the pulp of the tooth. It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis. Other causes can include occlusal trauma due to high spots after restoration work, extrusion from the tooth of root filling material, or bacterial invasion and infection from the gums. Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms. Etymologically, the name refers to inflammation (Latin, -itis) around (peri- ) the root tip or apex (-apical) of the tooth (-odont-). Periradicular periodontitis is an alternative term. Diagnosis
The radiographic features of periapical inflammatory lesions vary depending on the time course of the lesion. Because very early lesions
may not show any radiographic changes, diagnosis of these lesions relies solely on the clinical symptoms. More chronic lesions may show lytic (radiolucent) or sclerotic (radiopaque) changes, or both. Classification
Classification of periapical periodontitis is usually based on whether the process is acute/symptomatic or chronic/asymptomatic. (Note: alternative names for periapical periodontitis include apical periodontitis and periradicular periodontitis.) Acute periapical periodontitis
