What is a glandular odontogenic cyst?
What is a glandular odontogenic cyst?
Glandular odontogenic cyst (GOC) is a rare and uncommon jaw bone cyst of odontogenic origin described in 1987 by Gardener et al. as a distinct entity. It is a cyst having an unpredictable, potentially aggressive behavior, and has the propensity to grow in large size with relatively high recurrence rate.
What is the difference between odontogenic and Nonodontogenic cyst?
Odontogenic cysts arise from remnants of the odontogenic epithelium entrapped in bone or gingival tissue, while non-odontogenic cysts develop from epithelium of non-odontogenic origin.
Is primordial cyst and OKC same?
The initial terminology for an odontogenic keratocyst (OKC) was “primordial cyst,” as the origin of the lesion was thought to be the tooth primordium.
What is a radicular cyst?
Introduction. A radicular cyst is generally defined as a cyst arising from epithelial residues (cell rests of Malassez) in the periodontal ligament as a consequence of inflammation, usually following the death of the dental pulp.
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 common are odontogenic cysts?
There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%).
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 …
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.
What kind of cyst is a glandular odontogenic cyst?
Glandular odontogenic cyst (GOC) is a relatively new entity and is defined as “a cyst arising in the tooth-bearing areas of the jaws and characterized by an epithelial lining with cuboidal or columnar cells, both at the surface and lining, with crypts or cyst-like spaces within the thickness of the epithelium.” 1.
When did who diagnose glandular odontogenic cyst in Jaws?
Locally aggressive developmental cyst occurring within the jaws, recognized by WHO in 1992 as odontogenic in origin Noteworthy for locally aggressive growth, potential for recurrence and differential diagnostic considerations
How often does a glandular odontogenic cyst recur?
Recurrence occurred at a rate of 29.2%, within 0.5 to 7 years (mean, 2.9 years). Mean follow-up was also 2.9 years. Two patients had 3 recurrences each. Recurrence was associated with minor surgery such as enucleation or curettage; none of the patients treated by peripheral ostectomy, marginal resection, or partial jaw resection had a recurrence.
What are the characteristics of an odontogenic lesion?
Noteworthy for locally aggressive growth, potential for recurrence and differential diagnostic considerations While generally accepted as odontogenic in origin, lesion demonstrates glandular features including presence of cuboidal / columnar cells, mucin production, and cilia
