Dental cysts are usually caused due to root infection involving tooth decay. Untreated dental caries then allow bacteria to reach the level of the pulp, causing infection. The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots.
Gingival (alveolar) cysts of infants are mostly found in groups, but are frequently found as single nodules. They are present on the alveolar ridges. They are formed from fragments of dental lamina that remains within the alveolar ridge mucosa during tooth formation (odontogenesis).
The high prevalence of tooth impactions and dental infections that occur in the bones of the jaws is also significant to explain why cysts are more common at these sites. Cysts that arise from tissue(s) that would normally develop into teeth are referred to as odontogenic cysts. Other cysts of the jaws are termed non-odontogenic cysts. [2]
The median alveolar cyst is a rare cyst, occurring in the bony alveolus between the maxillary central incisors. It is distinguished from a periapical cyst by the fact that adjacent teeth are vital. It is distinguished from a periapical cyst by the fact that adjacent teeth are vital.
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
Recurrence is likely when treated by simple enucleation. Contributing causes include thin and fragile epithelium leading to incomplete removal, cyst extensions extending into cancellous bone, satellite cysts found in the wall, experience of the surgeon, formation of further new cysts from other remnants of the dental epithelium.

Stafne's defect is usually discovered by chance during routine dental radiography. [11] Radiographically, it is a well-circumscribed, monolocular, round, radiolucent defect, 1–3 cm in size, usually between the inferior alveolar nerve (IAN) and the inferior border of the posterior mandible between the molars and the angle of the jaw. It is one ...
