CYST

A cyst is defined as a pathologic cavity lined by epithelium. The common feature of all cyst is the stimulation of residual developmental epithelial cells leading to proliferation but not invasion of adjacent tissues.
As the mass enlarges, the epithelial cells in the center become positioned further from the blood supply at the periphery of the mass and soon the cells in the center die of nutritional deficiency, creating a lumen filled with fluid. This creates a hydrostatic pressure producing bone resorption, clinical expansion and sometimes pain also. The cyst continues to enlarge unless ENUCLEATION or MARSUPIALIZATION is performed by an oral surgeon.
