It is said that cysts in jaws enlarge when the intracystic fluid pressure in the cyst cavities increases, and the jaw bone is absorbed. The author investigated that LPO and the prostaglandin-like substances generated in the cyst fluids, damaged the cyst walls, that the value of phospholipid in the cyst walls decreased, that the values of TBA, free radical intensity, PGE, PGF2αincreased, and that the calcification of the jaw bones around the cysts decreased. These facts indicate that PGE generated in the cyst wall when a cyst is infected, acts on the resorption of the jaw bone. It can be regarded that the factor in the jaw cyst enlargement is PGE2.
