Mandibular Ameloblastoma is an uncommon, noncancerous (benign) tumor that usually occurs near the molars in the jaw. Ameloblastoma starts in the cells that make up your teeth’ protective enamel layer. 


Mandibular ameloblastomas are usually divided into types. However, they can also be divided by cell types. The four major types are as follows:

Conventional ameloblastoma. This is the most prevalent variety, which grows quickly and commonly in the lower jawbone, with about 10% of cases recurring after therapy.

Unicystic ameloblastoma. This type is less aggressive, although it happens more frequently in children. The tumor is usually found near the teeth in the rear of the lower jawbone. After treatment, recurrence is possible.

Peripheral ameloblastoma. This form is uncommon and affects the upper or lower jaw’s gums and oral tissue. After therapy, the tumor has a low probability of recurrence.

Metastasizing ameloblastoma. This type is extremely rare, and it’s identified by tumor cells that appear outside of the jaw’s leading site.


Ameloblastoma typically has no symptoms, but pain and a lump or swelling in the jaw might be signs and symptoms. If the tumor is not treated, it can grow quite large, altering the appearance of the lower cheek and jaw and displacing teeth out of place.


The following tests may be used to diagnose ameloblastoma:

  • Imaging tests
  • Tissue test


Treatment for mandibular ameloblastoma is determined by the size and location of the tumor and the variety and appearance of the cells involved. The following treatments may be used:

Surgery to remove the tumor. Ameloblastoma is often treated with an operation to remove the tumor. Because ameloblastoma frequently develops into surrounding jawbones, surgeons may remove the affected jawbone. 

Surgery to repair the jaw. If part of your jawbone is removed after surgery, surgeons can restore and replace it. This can help your jaw look and function better after that. The procedure may also make it easier for you to eat and speak.

Radiation therapy. After surgery, or if surgery isn’t an option, may require high-powered energy beam radiation therapy.

Prosthetics. Prosthodontists can replace lost teeth or other natural components in the mouth with artificial ones.

Supportive care. During and after treatment, a range of professionals can assist you with speech, swallowing, and eating challenges. Dietitians, speech and language therapists, and physical therapists are these specialists.
