scalloped bone destruction of the jaw
Introduction
Introduction X-ray examination showed that the jaw was "fan-shaped" bone destruction, and the edge was worm-like as one of the main symptoms of gingival cancer. In the oral squamous cell carcinoma composition ratio of the second or third, such as the upper gingival and lower gingiva are calculated separately, the lower gingival cancer ranks third, the upper gingival ranks fifth, lower gingival cancer is more common than upper gingival cancer. More men than women. Related to environmental factors, some external factors such as heat, chronic damage, ultraviolet rays, x-rays and other radioactive substances can become carcinogenic factors. For example, tongue and buccal mucosa cancer can occur in residual roots, sharp cusps, poor prostheses, etc. Long-term, often irritating parts.

In addition, internal factors such as neuropsychiatric factors, endocrine factors, immune status of the body, and genetic factors.

[clinical manifestations]
1. The lower gingiva is more than the upper gingiva, the growth is slower, and it is mostly ulcerated.
2. Invasion of the alveolar process and the jaw bone destroys the bone and can cause loosening and pain.
3. When the posterior development of the molar area and the pharynx is developed, it may cause difficulty in opening the mouth.
4. It can metastasize to cervical lymph nodes, and the mandibular gingival cancer metastasizes to the submandibular and axillary lymph nodes, and then to the deep cervical lymph nodes; the maxillary gingival cancer is transferred to the submandibular and deep cervical lymph nodes.
5. X-ray examination showed that the jaw bone was "fan-shaped" and the edge was worm-like.
Diagnosis
Differential diagnosis
diagnosis
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. Loose teeth and pain in the lesion.
3. When the posterior development of the molar region and the pharynx is developed, it may cause difficulty in opening the mouth; when the inferior alveolar nerve is affected, the lower lip may be numb.
4. The neck is swollen.
5. X-ray examination showed that the jaw was "fan-shaped" bone destruction, and the edge was worm-like.
6. Histopathological examination confirmed the diagnosis.
