Question: What Is Odontogenic Keratocyst?

What is the most common odontogenic tumor?

Odontomas are the most common odontogenic tumor.

There are two types of odontoma; compound and complex..

How is odontogenic infection treated?

Infections from teeth that are limited to the oral cavity or superficial anatomic spaces are primarily managed on an outpatient basis with control of the etiological factor, antibiotics, and surgical incision and drainage if necessary.

What does odontogenic mean?

An odontogenic infection is an infection that originates within a tooth or in the closely surrounding tissues. … It is estimated that 90-95% of all orofacial infections originate from the teeth or their supporting structures and are the most common infections in the oral and maxilofacial region.

What is the best antibiotic for mouth infections?

The goals of therapy are to treat the dental infection and prevent further complications. Amoxicillin is still the first-line drug of choice but with 34% of Prevotella species resistant to amoxicillin, the alternatives of amoxicillin/clavulanate, clindamycin, and metronidazole need to be considered.

How are odontogenic infections best managed?

Penicillin in conjunction with metronidazole provides excellent bacterial coverage for most odontogenic infections and should be considered the antibiotic of choice. Clindamycin also provides excellent coverage and should be used for the penicillin-allergic patient or in the setting of penicillin failure.

Why is OKC called KCOT?

In recent years, World health organization (WHO) recommended the term cystic neoplasm (now known as keratocystic odontogenic tumor (KCOT)) for this lesion, as it better reflects aggressive clinical behavior, histologically high mitotic rate and association with genetic and chromosomal abnormalities.

What causes odontogenic cysts?

Odontogenic jaw tumors and cysts originate from cells and tissues that are involved in normal tooth development. Others tumors that affect the jaws can be nonodontogenic, meaning that they can develop from other tissues within the jaws that are not related to the teeth.

What is Adenomatoid odontogenic tumor?

Adenomatoid odontogenic tumor (AOT) is a well-recognised slow growing benign tumor derived from complex system of dental lamina or its remnants. This lesion is categorised into three variants of which the more common variant is follicular type which is often mistaken for dentigerous cyst.

What is a odontogenic tumor?

An odontogenic tumor is a neoplasm of the cells or tissues that initiate odontogenic processes. Examples include: Adenomatoid odontogenic tumor. Ameloblastic fibroma. Ameloblastoma, a type of odontogenic tumor involving ameloblasts.

What is the best antibiotic for dental infection?

Antibiotics of the penicillin class, such as penicillin and amoxicillin, are most commonly used to help treat tooth infections. An antibiotic called metronidazole may be given for some types of bacterial infections. It’s sometimes prescribed with penicillin in order to cover a larger variety of bacterial species.

What is the most common odontogenic cyst?

Dentigerous cysts are the most common of odontogenic cysts and can occur at any tooth location, but most often occur in third molars and maxillary canines, locations most often involved in tooth impaction.

How is OKC treated?

In healthy patients, enucleation of OKC’s followed by the application of Carnoy’s and excision of the overlying mucosa in the region of attachment to the OKC should be the treatment of choice.

Why is OKC aggressive?

An extensive volume of research has demonstrated that the epithelium of OKCs has a unique growth potential compared with that of other cysts (2,3). … … These characteristics can explain the aggressive clinical behavior, a distinctive histopathology and the high frequency of recurrence in OKC.

What is Gorlin Goltz syndrome?

Gorlin-Goltz syndrome is an autosomal dominant disorder with a high degree of penetrance[1] and variable expressivity. [2] It is characterized by basal cell carcinomas, odontogenic keratocysts, palmar and/or plantar pits, and ectopic calcifications of the falx cerebri. More than 100 minor criteria have been described.

Why is OKC recurrence so high?

[36] reported that a recurrent OKC may develop in three different ways: By incomplete removal of the original cyst lining; by the retention of daughter cysts, from microcysts or epithelial islands in the wall of the original cyst or by the development of new OKC from epithelial off-shoots of the basal layer of the oral …
