Chronic periapical periodontitis
Chronic (or asymptomatic) periapical periodontitis. Related lesions
In addition to periapical abscesses, periapical periodontitis can give rise to various related lesions, including periapical granulomas and cysts. A periapical granuloma (also referred to as an apical granuloma or radicular granuloma) is a mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital (dead) tooth. (Although not a true granuloma, given the absence of granulomatous inflammation, the term periapical granuloma is widely accepted.) Treatment
Treatment options may include antibiotic therapy (in the short term, augmented by chewing gum), root canal therapy, or extraction. Epidemiology
Periapical periodontitis of some form is a very common condition. The prevalence of periapical periodontitis is generally reported to vary according to age group, e.g. 33% in those aged 20–30, 40% in 30- to 40-year-olds, 48% in 40- to 50-year-olds, 57% in 50- to 60-year-olds and 62% in those over the age of 60. Most epidemiologic data has been generated in European countries, especially Scandinavia. While millions of root canal treatments are carried out in the United States alone each year, total numbers of such cases do not provide reliable indicators of frequency, even for symptomatic periapical periodontitis (given that root canal treatment is not always indicated or complied with, and may also be performed in the absence of periapacial periodontitis).

Enophthalmos is a posterior displacement of the eyeball within the orbit. It is due to either enlargement of the bony orbit and/or reduction of the orbital content, this in relation to each other.It should not be confused with its opposite, exophthalmos, which is the anterior displacement of the eye. It may be a congenital anomaly, or be acquired as a result of trauma (such as in a blowout fracture of the orbit), Horners syndrome (apparent enophthalmos due to ptosis), Marfan syndrome, Duanes syndrome, silent sinus syndrome or phthisis bulbi.
