An ameloblastoma is a rare benign tumour of the upper or lower jaw.
bec there is other type of ameloblastoma called ameloblastoma carcinoma.. 2nd it doesn't change its shape.. 3rd histopathology shows that it has an inactive connective tissue .. and an increased epithelium thus it doesn't act with the C.T to form a tooth ..:)
because it's simple :D
Amelobblastoma may be discovered in a routine dental x-ray. Once discovered your dentist may recommend tests such as additional x-rays, MRI, and CT Scan. Your dentist may also remove a sample of tissue for testing to further diagnose the condition.
Ameloblastoma is a rare, benign tumor that originates from the dental epithelium, specifically the cells responsible for enamel formation. It typically occurs in the jaw, particularly the mandible, and can lead to local bone destruction and expansion. While it is generally slow-growing, it can be aggressive and may recur if not completely removed. Treatment usually involves surgical excision to ensure complete removal and reduce the risk of recurrence.
A high reccurence rate with a 'scoop and curettage approach' (just scooping out the tumor) at rates as high as 95%. Lower reccurence rates with a resection of the area (removing the tumor along with all adjacent soft tissue/bone that was affected with margins on all sides) at only about 5%. This surgery is more radical as people often lose teeth and large sections of jawbone but it is better when looking at the rate of reccurence.
the word dentigerous means containing a tooth . these are epithelial saced formed around the crown of an unerpted tooth or dental anomaly " odontome" . the cyst radiographically shows an enlargment of the follicular spce around unerupted tooth originates from the accumlation of fluids between reduced enamle epith. and the crown of the tooth . it is most frequent in Children and adolescents in which it is more frequent in the Mandible than the maxilla with no predominant sex predilcaton . the most effected teeth are the lower third molar in the upper canines " due to their late eruption time " . the cyst is painless and symptomless , the pt.'ll seek ttt for the facila assymetry caused by the prgressive enlargment of the cyst . Radiographically : Unilocular Radiolucency associated to unerupted tooth, well marked boarders of the cyst with scelorotic rim , Adjacent teeth's rooth may be resorped . Histologically : Cyst wall > Conn. Tissue capsule free of inflammatory cells, unless the cyst is infected . it is attached to the CEJ of the involved tooth . the cyst may frequently contains secreting cells . * there is a poteintal for ameloblastoma development out of the Dentigerous Cyst Dr. Moh'd S.
