What causes OKC cyst?

Contributing causes include thin and fragile epithelium leading to incomplete removal, cyst extensions extending into cancellous bone, satellite cysts found in the wall, experience of the surgeon, formation of further new cysts from other remnants of the dental epithelium.

What is an OKC cyst?

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.

Is an odontogenic keratocyst a tumor or a cyst?

Abstract. The odontogenic keratocyst (OKC, currently designated by the World Health Organization as a keratocystic odontogenic tumor) is a locally aggressive, cystic jaw lesion with a putative high growth potential and a propensity for recurrence.

Is odontogenic keratocyst benign?

Odontogenic keratocysts (OKCs) are benign lesions of odontogenic origin accounting for about 10% of all odontogenic cysts and characterised by an aggressive behaviour.

Is Odontogenic Keratocyst cancerous?

odontogenic keratocyst (OKC) is considered a benign cyst that can assume a locally aggressive and destructive behavior. Atypia of its lining is uncom- mon, and frank malignant degeneration is rare. Presence of these changes may remain clinically undetected and carry a significant influence on treatment and outcome.

Which cyst has highest recurrence rate?

Abstract. Odontogenic keratocyst (OKC) is of particular interest because of its high recurrence rate and aggressive behavior.

Can odontogenic keratocyst be malignant?

Is Keratocyst a tumor?

The keratocystic odontogenic tumor (KCOT), formerly known as the odontogenic keratocyst (OKC), received its new designation in order to better convey its neoplastic nature [1]. It is a benign developmental odontogenic tumor with many distinguishing clinical and histologic features.

Do Dentigerous cysts recur?

Dentigerous cyst (DC) is one of the most common odontogenic cysts of the jaws and rarely recurs.

Can dental cysts be cancerous?

The risk is high when the cyst is in the premolar region. Ameloblastoma or jaw tumor: These are rare tumors that mainly affect the jaw near the molars or wisdom teeth. They arise from cells that form the enamel. If left untreated, the swelling becomes cancerous and may spread to the lungs or lymph nodes.

Are cysts in the jaw common?

Overview. Jaw tumors and cysts are relatively rare growths or lesions that develop in the jawbone or the soft tissues in the mouth and face. Jaw tumors and cysts — sometimes referred to as odontogenic or nonodontogenic, depending on their origin — can vary greatly in size and severity.

What kind of doctor do you see for a cyst in your mouth?

Oral Mucous Cyst Treatment See your doctor, your child’s pediatrician, or your dentist for expert advice. These are the two types of treatment a doctor or dentist most commonly uses: Removing the gland. The dentist or doctor may use a scalpel or laser to remove the salivary gland.

WHO removes a jaw cyst?

During surgery, your surgeon removes your jaw tumor or cyst, which may include removing nearby teeth, tissue and jawbone, and sends it to the lab for examination. A pathologist examines the removed tissue and reports a diagnosis during the procedure so that the surgeon can act on this information immediately.

What is OKC cysts of the oral cavity?

It is one of the most aggressive odontogenic cysts of the oral cavity. OKC is known for its rapid growth and its tendency to invade the adjacent tissues including bone. It has a high recurrence rate and is associated with the basal cell nevus syndrome.[2]

What is OKC in dentistry?

OKC is the one of the rare odontogenic cysts, which attracts many researchers due to its unique characteristics. OKC originates from the dental lamina remnants in the mandible and maxilla before odontogenesis is complete. It may also originate from the basal cells of overlying epithelium.

What is the best treatment for an OKC cyst?

This procedure relieves pressure from the cystic fluid, allowing reduction of the cystic space and facilitating bone apposition to the cystic walls.[1] Currently, treatment involving careful and aggressive enucleation with close follow-up has been advocated for the OKC.

Can an OKC cyst be removed in one piece?

Because the lining of the OKC is characteristically thin and friable, removal of the cysts in one piece may be difficult. Great care must therefore be taken to ensure complete removal of the cyst lining, without leaving behind remnants attached to the adjacent bone or soft tissue.
