Tooth-like hard tissue in the jawbone

Introduction A dental tumor (oral and maxillofacial surgery) is a odontogenic tumor that grows in the jaw bone and is formed by abnormal development of one or more tooth germ tissues. The tumor may contain various tooth germ tissues or teeth at different developmental stages. The number varies from one to several tens of, and the shape is irregular. It may be similar to a normal tooth. It may also have no tooth shape. It is just a group of disordered hard tissues. It is surrounded by a fibrous membrane and arranged under the microscope. Regular enamel, dentin and cementum.

Cause

There is no clear cause.

an examination

Growing in the jaw, it is formed by abnormal development of one or more tooth germ tissues. The tumor may contain various tooth germ tissues or teeth at different developmental stages, and the number may vary from several to dozens. The rules may be similar to normal teeth, or they may be without the shape of a tooth, just a mess of hard tissue.

Differential diagnosis

It is differentiated from gingival cancer.

The performance of gingival cancer is:

1. The gums are not healed for a long time, and the enlargement is faster, or the wounds are not cured after a tooth extraction, and the tumor is prominent.

2. When the posterior development of the posterior molar region and the pharynx is made, it may cause difficulty in opening the mouth; when the inferior alveolar nerve is affected, the lower lip may be numb.

3. The lower gingiva is more than the upper gingiva, the growth is slower, and it is mostly ulcerated.

4. Invasion of the alveolar process and the jaw bone destroys the bone and can cause loosening and pain.

5. The cervical lymph node metastasis can be caused by cervical lymph node metastasis. The mandibular gingival cancer metastasizes to the submandibular and axillary lymph nodes, and then metastasizes to the deep cervical lymph nodes. The maxillary gingival cancer is transferred to the affected side of the jaw and neck depth. Lymph nodes.

6. X-ray examination showed that the jaw bone was "fan-shaped" and the edge was worm-like. Growing in the jaw, it is formed by abnormal development of one or more tooth germ tissues. The tumor may contain various tooth germ tissues or teeth at different developmental stages, and the number may vary from several to dozens. The rules may be similar to normal teeth, or they may be without the shape of a tooth, just a mess of hard tissue.
