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.

Intraoral X-rays or a 3-D cone beam scan of the affected area can be used to obtain radiological images and confirm diagnosis of cysts in the periapical area. Circular or ovoid radiolucency surrounding the root tip of approximately 1-1.5 cm in diameter is indicative of the presence of a periapical cyst. [2]
In 1890, W.D. Miller, considered the father of oral microbiology, was the first to associate pulpal disease with the presence of bacteria. [11] This was confirmed by Kakehashi, who, in 1965, proved that bacteria were the cause of pulpal and periradicular disease in studies using animal models; pulpal exposures were initiated in both normal and germ-free rats, and while no pathologic changes ...
In some cases, the pain presents as a long dull ache as this is due to necrosis of the apical nerves being the last part of the pulp to necrose. Therefore, the pain is from the apical nerves, which have residual vitality remaining when the majority of the pulp is necrosed due to the supply of blood to the more medial parts of the apical nerve.

Periradicular surgery should be very considered where previous endodontic treatment has failed, and possible re-root treatment is the preferred option. [4] If re-root treatment is not possible, will not correct the problem or patient factors prevent it, periradicular surgery is indicated.
Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.
Condensing osteitis, also known as focal sclerosing osteomyelitis, is a rare periapical inflammatory condition characterized by the formation of sclerotic bone near the roots of premolars and molars. This condition arises as a response to dental infections, such as periapical pulp inflammation or low-intensity trauma.
A phoenix abscess is an acute exacerbation of a chronic periapical lesion. It is a dental abscess that can occur immediately following root canal treatment.Another cause is due to untreated necrotic pulp (chronic apical periodontitis). [1]
