What are odontogenic Keratocysts?
What are odontogenic Keratocysts?
Odontogenic keratocyst (OKC) is the cyst arising from the cell rests of dental lamina. It can occur anywhere in the jaw, but commonly seen in the posterior part of the mandible. Radiographically, most OKCs are unilocular when presented at the periapex and can be mistaken for radicular or lateral periodontal cyst.
How is odontogenic keratocyst treated?
Multiple surgical approaches were introduced including decompression, marsupilization, enucleation with or without adjunct (Carnoy’s solution, cryotherapy), and resection. Depending on other studies KCOT can be conservatively treated with enculation and application of Carnoy’s solution or cryotherapy.
How common is odontogenic keratocyst?
Odontogenic keratocysts make up around 19% of jaw cysts. In the WHO/IARC classification of head and neck pathology, this clinical entity had been known for years as the odontogenic keratocyst; it was reclassified as keratocystic odontogenic tumour (KCOT) from 2005 to 2017.
Is odontogenic keratocyst painful?
Clinical Features and Imaging Clinically, odontogenic keratocysts (OKCs) generally present as a swelling, with or without pain.
Why do odontogenic Keratocysts recur?
OKC is known for its rapid growth and its tendency to invade the adjacent tissues including bone. It has a high recurrence rate of 16 to 30%. Odontogenic keratocysts are generally thought to be derived from either the epithelial remnants of the tooth germ or the basal cell layer of the surface epithelium.
What are the non odontogenic tumors?
Primary intraosseous tumors of non-odontogenic origin arising in children and adolescents include osteoma and osteoblastoma, Langerhans cell histiocytosis, desmoplastic fibroma, inflammatory myofibroblastic tumor, juvenile ossifying fibroma, Ewing sarcoma and osteosarcoma, and primary intraosseous lymphoma.
What does odontogenic tissue mean?
Odontogenic Tissue. The tissue that forms the tooth . It consists of the dental pulp, dentin, enamel, cementum, odontogenic epithelium, and periodontium.
What does odontogenic cysts mean?
Odontogenic cyst are a group of jaw cysts that are formed from tissues involved in odontogenesis (tooth development). Odontogenic cysts are closed sacs, and have a distinct membrane derived from rests of odontogenic epithelium. It may contain air, fluids, or semi-solid material.
Who classification of odontogenic tumors?
An odontogenic tumor is a neoplasm of the cells or tissues that initiate odontogenic processes. Examples include: Adenomatoid odontogenic tumor. Amelobastic fibroma. Ameloblastoma, a type of odontogenic tumor involving ameloblasts.
