KERATOCYSTS Meaning and
Definition
-
Keratocysts, also known as odontogenic keratocysts or keratocystic odontogenic tumors (KCOTs), are a type of cystic lesion that primarily affects the jaws. These lesions are benign, but they have the potential to grow rapidly and cause significant damage if left untreated.
Keratocysts are derived from the dental lamina or remnants of the enamel organ, which are important structures involved in tooth development. They typically occur in the posterior mandible (lower jaw), particularly around the third molars (wisdom teeth), but can also be found in other areas of the jaws. Clinically, keratocysts often present as a painless swelling or a radiolucent (dark) area on dental X-rays.
Histologically, keratocysts are characterized by a lining of stratified squamous epithelium. The epithelial lining is typically thin, with a distinctive parakeratinized or orthokeratinized layer. These cysts have a high propensity for recurrence, which is one of their defining features. Thus, appropriate treatment involves complete removal of the cyst lining and any associated tooth or teeth to prevent the likelihood of recurrence.
If left untreated or not removed entirely, keratocysts can expand and cause destruction of surrounding structures such as the jawbone, adjacent teeth, and the sinus cavity in the maxilla (upper jaw). Due to their potential for growth and recurrence, management of keratocysts often requires close clinical and radiographic follow-up to monitor for any signs of recurrence.

Etymology of KERATOCYSTS
The word "keratocysts" is derived from two roots: "kerato-" and "-cysts".
1. "Kerato-" comes from the Greek word "keras" (κέρας), meaning "horn" or "keratin". In medical terminology, "kerato-" typically refers to conditions related to the cornea, the transparent front part of the eye.
2. "-Cysts" originates from the Greek word "kustis" (κύστις), meaning "bladder", "cyst", or "sac". In medical terminology, "-cysts" typically refers to sac-like structures or pathological cavities within tissues.
When combined, "keratocysts" refers to cysts or sac-like structures lined with keratinized epithelial cells.
