What are non odontogenic tumors?

Nonodontogenic tumors are those orofacial tumors which do not arise from the dental epithelial and mesenchymal. , Similar to every orofacial tumor, they constitute a major health problem.

What is non odontogenic lesion?

A lesion associated with an impacted tooth frequently indicates an odontogenic origin. Nonodontogenic lesions, however, develop from osseous origin and are not tooth-related. These lesions usually, but not always, consist of a group of pathologies which may be seen anywhere in the axial skleton.

WHO classification benign odontogenic tumors?

BENIGN ODONTOGENIC TUMORS, EPITHELIAL Ameloblastomas were classified as solid/multicystic, extraosseous/peripheral, desmoplastic, and unicystic types in the 2005 classification. The 2017 classification has been narrowed to ameloblastoma, unicystic ameloblastoma, and extraosseous/peripheral types.

What are the odontogenic tumors?

Odontogenic tumors are a group of neoplastic growths that originate from the tissues responsible for tooth formation and the periodontal apparatus of the jaw. Odontogenic tumors usually present as radiolucent defect, which makes diagnosis somewhat confusing while differentiating them from cysts.

What are non-odontogenic infections?

Odontogenic infections include dental caries, periodontal disease, and suppurative deep space infections. Non-odontogenic infections include pyogenic infections of the face and neck, infections of the oral mucosa, oropharyngeal candidiasis, sialadenitis and parotitis.

What is non-odontogenic cyst?

Introduction. A cyst is a pathologic cavity lined by epithelium and filled with fluid or semifluid content and may either locate in soft tissue or within the jaw bone, originating in odontogenic or nonodontogenic tissues. Jaw bones show predilection for odontogenic cysts, whereas nonodontogenic cysts are uncommon.

What is non-odontogenic?

Non-odontogenic cysts are usually discovered during a routine examination. These lesions arise from the non-odontogenic (non-tooth forming) tissue. By definition, the cysts are lined by epithelium. Cysts within the oral cavity vary in their clinical appearance, incidence, histology, behavior, and management.

What is non odontogenic cyst?

WHO classification odontogenic cysts 2005?

Type 1: simple cystic. Type 2: CCOT associated with an odontoma. Type 3: with ameloblastomatous-like proliferation. Type 4: associated with other benign odontogenic tumors other than odontoma.

Where are odontogenic tumors derived?

Background. Odontogenic tumours (OT) are rare entities derived from epithelial, ectomesenchymal and/or mesenchymal components of the odontogenic (or tooth-forming) apparatus and make up less than 5% of all oral tumours [1, 2].

What are the different infections or diseases from odontogenic and non-odontogenic?

What is non odontogenic?

What are the different types of odontogenic tumors?

Ameloblastic carcinoma » B. Clear cell odontogenic carcinoma » C. Adenomatoid odontogenic tumor » D. Calcifying epithelial odontogenic tumor » E. Squamous odontogenic tumor – II.

What are the histologic features of adenomatoid odontogenic tumors?

Adenomatoid Odontogenic Tumor • Histologic Features • The lesion is usually surrounded by a thick, fibrous capsule. • The tumor is composed of spindle-shaped epithelial cells that form sheets, strands or whorled masses with little connective tissue.

What are the clinical features of calcifying epithelial odontogenic tumor?

Calcifying Epithelial Odontogenic Tumor • Clinical Features • Patient Age: 2nd to 10th decades (mean age 40 years). • Gender Predilection: no reported sex predilection.

What are non odontogenic cysts?

WHAT ARE NON ODONTOGENIC CYSTS?  According to Shafer’s Cysts in the orofacial region not essentially derived or related to the odontogenic apparatus are called non odontogenic cysts. 3.
