Simple excision Enucleation and cryotherapy. The epithelial lining is thin with even thickness and parakeratinised with columnar cells in the basal layer which have focal reverse polarisation nuclei are on the opposite pole of the cell. Wide local surgical excision to remove the whole cyst lining.
Under the microscopeOKCs vaguely resemble keratinized squamous epithelium ;  however, they lack rete ridges and often have an artifactual separation from their basement membrane. Over the years, the oral pathologists have been trying to understand the nature, identification, and management of diseases affecting the oral and maxillofacial regions.
Carnoy's solution fixative ethanol, chloroform and acetic acid which is usually used in conjunction with excision and curretage. Marsupialization which involves the surgical opening of the cyst cavity and a creation of a marsupial -like pouch. These can go on to form 'satellite' or 'daughter' cysts, leading to an overall multilocular cyst.

They mention the mechanisms that favor growth and expansion of OKCs are high proliferation rate, over expression of antiapoptotic proteins bcl-2 and expression of matrix metalloproteinase MMPs 2 and 9. The best evidence to suggest that this type of cyst is not a neoplasm is that it responds very well to marsupialisation. This article has been cited by other articles in PMC. Meghanand T. Mostly these arguments revolve around whether to treat OKC as a cyst or as a benign neoplasm.
Curettage involving simple excision and scraping-out of cavity. This article is an effort to provide an overview of various aspects of OKC with emphasis on nomenclature, recurrence, molecular aspects, and management of OKC. The odontogenic keratocyst OKC is an enigmatic developmental cyst that deserves special attention. Cavity wall can be treated with the fixative either before enucleation to kill the Claverack NY sexy women of the wall or added after curretage to bony walls, killing any residual epithelial cells to a depth of mm.
Among the latter type most notorious are odontogenic keratocyst OKC. Toller[ 4 ] as early as suggested that OKC should be considered as a benign neoplasm rather than a conventional cyst mainly because of their clinical classiied. Histopathological features that predict recurrences. Recurrence is usually seen within 5 years of treatment. Abstract The classification of odontogenic cysts is complicated and can create confusion for both clinicians and pathologists.
The surgeons since the beginning have been experimenting with OKC treatment modalities to find a way of treating it without any recurrences. Benign neoplasm? The histopathology of OKC is typical and have been well characterized. Intermediate magnification of an odontogenic keratocyst High magnification of an odontogenic keratocyst. In this process, all what has been classjfied is to classify, classify, and reclassify these diseases.
However, resolution can take up to 20 months and patients are required to clean the open cavity and irrigate it. Flash amateur Pontefract multilocular and unilocular cysts can be treated more conservatively through enucleation and curretage. Treatment[ edit ] Large odontogenic keratocyst xlassified impacted wisdom teeth superficial to lesion As the condition is quite rare, opinions among experts about how to treat OKCs differ.
OKC originates from the dental lamina remnants in the mandible and maxilla classifjed odontogenesis is complete. Whatever modality Wife seeking casual sex Vance AFB been implied, none of these have shown to completely prevent recurrence of the lesion, the problem is still compounded in case of NBCCS and multiple lesions.
OKC was first identified and described in On the other hand, eminent pathologists have been struggling to determine the true nature of OKC so that a definite line of action can be devised. Pindborg and Hansen[ 10 ] were the first to point out the aggressive behavior of OKC. Ahlfors and others[ 11 ] in suggested OKC to be classified as a true benign cystic epithelial neoplasm and suggested modified treatment schedules.
Early findings of recurrence can be easily treated with minor surgery and curretage.
Odontogenic keratocyst: what is in the name?
It has characteristic histopathological and clinical features; but, what makes this cyst special is its aggressive behavior and high recurrence rate. Shear[ 12 ] published his extensive work on the aggressive nature of the odontogenic keratocyst and finally labeled it as a benign cystic neoplasm. Many prior attempts have been made to classify these cysts in a logical manner. This diverse group of lesions exhibit varying presentations ranging from a small innocuous Wauwatosa xxx adult swinger, which may be detected accidentally or may present as a highly aggressive and destructive lesion that may even transform into a malignancy.
Despite of many classifications and nomenclature, unfortunately the clinicians still have to face clawsified in the management of this commonly found jaw lesion.

Marsupialisation in slow shrinkage of the cyst allowing later enucleation. This supports the concept that KCOT represents a neoplasm. The epithelium can separate from the wall, resulting in islands of epithelium. Contributing causes include thin and fragile epithelium leading to incomplete removal, cyst extensions lkc 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.
A Cochrane review found that there is currently no high quality evidence to suggest the effectiveness of specific treatments for the treatment of odontogenic keratocysts. E-mail: moc.
Histology[ edit ] Odontogenic keratocysts have a diagnostic classitied appearance. It may also originate from the basal cells of overlying epithelium. Due to high recurrence rate, late detection when the cyst has grown very large and causation by tumour suppressor gene inactivation, some have classified OKCs as benign neoplasms.
Extensive cysts may require a bone graft after bone resection and reconstruction of the area. Furthermore, preliminary have shown over-expression and amplification of genes located in classifjed. OKC exhibits putative high growth potential and high recurrence rate due to its nature of forming compartments within.
OKC is the one of the rare odontogenic cysts, which attracts many researchers due to its unique characteristics.

Due clasxified areas of focal inflammation, a larger biopsy is required for correct diagnosis of odontogenic keratocysts. Regezi and others[ 13 ] have attempted to explain the pathogenetic mechanisms of OKC. Used with care near mandibular canal and the neurovascular bundle within. The OKC is an enigmatic developmental cyst that deserves special attention. Treatment OKC is well known for their strong tendency to recur.
