Doggerel:

The white patch is annoying, and I feel depressed with a sigh.

Active treatment is not difficult, and regular review is promising.

Brother Ya:

"Sister Ya, what are these white" lines "on my cheek?"

Tooth elder sister:

"Where?"

Brother Ya:

"Right here. Inside my cheek, this position where my tongue licks. "

Tooth elder sister:

"This is the tooth mark line, it's okay."

Brother Ya:

"You take a good look again, it is really a tooth mark line (also called buccal white line, located in the buccal mucosa corresponding to the occlusal line of bilateral posterior teeth, and it is a continuous white or grayish white line, which is consistent with the shape of dentition and extends horizontally and longitudinally. Most of them are caused by continuous stimulation of teeth during chewing, which is common in adults and has no conscious symptoms. )? Not anything else. "

Tooth elder sister:

"I look good, the elder brother of the tooth. Don't worry! "

Brother Ya:

"Oh, by the way, what does a white dot look like?"

Tooth elder sister:

"Well, why is Brother Ya suddenly interested in white spots?"

Brother Ya:

"I just read your spoken English textbook and happened to see the white spot. The book said that "white spots are precancerous lesions", so I quickly looked at whether there were such white plaques in my mouth. "

Tooth elder sister:

"Ha ha, the elder brother of the tooth has learned to use now! Now that you ask, I'll tell you one thing. Oral leukoplakia refers to white plaque or plaque on oral mucosa, which can not be diagnosed as any other disease by clinical and histopathological methods. Clinically, leukoplakia can be divided into two stages: temporary diagnosis and positive diagnosis. "

Brother Ya:

"What do you mean?"

Tooth elder sister:

"When white mucosal plaques are found and cannot be diagnosed as other diseases, temporary diagnosis can be made first (excluding white keratosis, that is, local white keratotic plaques or plaques formed by long-term mechanical or chemical stimulation of oral mucosa). After removing the local stimulation factor of 1-2 weeks, the color of white loss becomes lighter, the range is obviously reduced, or even disappears). If the damage still exists after 1-3 months of observation after removing some local factors, it can be diagnosed as positive and needs to be further diagnosed according to the biopsy results. "

Brother Ya:

"What caused the white spot?"

Tooth elder sister:

"There are many causes, and the incidence of leukoplakia is more than the long-term stimulation of local factors and some systemic factors."

1, smoking and other stimuli. It is found that the incidence of leukoplakia is directly proportional to the length of smoking history and the amount of smoking. Smoking every day * Smoking for more than 400 years increases the risk of leukoplakia. According to the types of cigarettes from high to low, the order is: smoking dry >; Smoke cigarettes > smoke fog. In addition, drinking spirits, eating overheated food, chewing betel nut and other local stimuli can also promote the occurrence of white spots;

2. Candida infection. Candida albicans can be detected in the mouth of some patients with leukoplakia. According to animal experiments, it was found that the strain was closely related to white spot disease.

3. Systematic factors. Including trace elements, changes in microcirculation and so on.

Brother Ya:

"What kind of white spots are easy to' degenerate'?"

Tooth elder sister:

1, older, such as over 60 years old;

2. Long-term heavy smoking;

3. White spots are located at the edge, abdomen and floor of the tongue;

4. Epithelial dysplasia is more likely to become malignant.

5, the lesion time is long;

6. Those with irritating pain or spontaneous pain;

7. Verrucous, granular, ulcer or erosion, accompanied by candida infection.

Brother Ya:

"If the pathological diagnosis is leukoplakia, how to treat it?"

Tooth elder sister:

1, remove the stimulating factors and actively adjust the mentality. Such as quitting smoking and drinking, eating less spicy food, pulling out residual roots and crowns, and pulling out bad prostheses;

2. Combination of traditional Chinese and western medicine;

3, regular review, found unwell biopsy as soon as possible.

Don't talk about cancer discoloration, because as long as active treatment and psychological adjustment are made, good results can be achieved and the disease can be controlled in the "bud" state.

Note: Oral lichen planus and oral submucosal fibrosis are both "precancerous states". Oral leukoplakia and oral erythema belong to precancerous lesions.
