Dental tumor

Introduction to dental tumor A dental tumor 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, and the number may vary. From dozens to dozens, the shape is irregular, it may be similar to a normal tooth, or it may be without the shape of a tooth. It is composed of a disordered hard tissue, surrounded by a fibrous membrane, irregularly arranged enamel and teeth under the microscope. Nature and cementum. basic knowledge The proportion of sickness: 0.003%-0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: Gum cancer Gingivitis

Cause of dental tumor

Abnormal dental tissue (78%):

A dental tumor is a hamartoma or a developmental malformation of an adult tooth tissue, not a true tumor. The mass contains mature enamel, dentin, cementum and pulp tissue.

Dental disease prevention

It is very important to maintain a good attitude, to maintain a good mood, to have an optimistic, open-minded spirit, and to be confident in the fight against disease. Don't be afraid, only in this way can you mobilize your subjective initiative and improve your body's immune function.

Dental complication Complications Gingival cancer gingivitis

A small number of oppressors can have pain.

Symptoms of dental tumors Common symptoms Teeth abnormal gums gums swollen gums dark red or dark red jaws like hard tissue

1. Slowly enlarged bone swelling, hard, nodular, missing teeth.

2. More asymptomatic, a small number of oppressors can have pain.

3. Histopathological examination confirmed the diagnosis.

Dental examination

1. For the clinical manifestations are more typical, the preoperative diagnosis has been more clear to check the project to check the box limit "A".

2. For the clinical manifestations are atypical, the differential diagnosis is more difficult, and the part of the tumor where the conventional film overlaps is more likely to include the inspection frame limit "B".

3. X-ray film shows bone expansion, there are many different sizes and shapes, images of hypoplasia, or a group of images with transmission like dental tissue. There is a clear shadow between the image and normal tissue, which is the capsule of the tooth tumor.

Diagnosis and diagnosis of dental tumor

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 unhealed after the tooth extraction, and the mass 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.
