Gingival cyst, also known as Epstein's pearl, is a type of cysts of the jaws that originates from the dental lamina and is found in the mouth parts. It is a superficial cyst in the alveolar mucosa . It can be seen inside the mouth as small and whitish bulge.
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
Keratocyst (in the jaws, these can appear solitary or associated with the Gorlin-Goltz or Nevoid basal cell carcinoma syndrome. Paradental cyst; Periapical cyst (The periapical cyst, otherwise known as radicular cyst, is the most common odontogenic cyst.) Radicular cyst (associated with the roots of non-vital teeth, also known as Periapical cyst)
In eukaryotes, the cell cycle consists of four main stages: G 1, during which a cell is metabolically active and continuously grows; S phase, during which DNA replication takes place; G 2, during which cell growth continues and the cell synthesizes various proteins in preparation for division; and the M phase, during which the duplicated ...
Dentigerous cyst, the second most prevalent cyst, is associated with the crown of non-erupted tooth. Odontogenic keratocyst This lesion may be associated with the Nevoid basal cell carcinoma syndrome. Buccal bifurcation cyst which appears in the buccal bifurcation region of the mandibular first molars in the second half of the first decade of ...
Periapical cysts exist in two structurally distinct classes: Periapical true cysts - cysts containing cavities entirely surrounded in epithelial lining. Resolution of this type of cyst requires surgical treatment such as a cystectomy. [10] Periapical pocket cysts - epithelium lined cavities that have an opening to the root canal of the affected ...
These three types form from a mass of epithelial cells known as the epithelial cuff between the tooth and the mouth. [36] Much about gingival formation is not fully understood, but it is known that hemidesmosomes form between the gingival epithelium and the tooth and are responsible for the primary epithelial attachment.

Cells with a defective G 2-M checkpoint will undergo apoptosis or death after cell division if they enter the M phase before repairing their DNA. [1] The defining biochemical feature of this checkpoint is the activation of M-phase cyclin-CDK complexes, which phosphorylate proteins that promote spindle assembly and bring the cell to metaphase.
