Mother said that betel nut is not a good thing and told me not to eat it again.

What harm does betel nut addiction have?

1. From the point of view of environmental sanitation, greedy people spit betel nut juice indiscriminately, which is harmful to the city appearance and environmental sanitation.

From a medical point of view, chewing betel nut is harmful to human health.

What is the impact on human health:

1. When calcium and betel nut juice fill the mouth to form dental calculus,

Because of long-term hard chewing, teeth are consumed, and even teeth are cracked or broken.

2. Influence on temporomandibular joint:

Due to occlusal changes caused by dentin occlusion and temporomandibular joint surface wear, as well as temporomandibular joint pain and diseases, there will be sound and joint pain when opening and closing, which is not only pain,

And the treatment is quite difficult.

3. Effect on periodontal tissue:

Because betel nut fiber is quite thick and hard, it will stab gums or block teeth.

It causes inflammation due to the compression of the interdental papilla, and also damages the periodontal ligament due to hard chewing, causing inflammation, swelling and pain around the root.

On the other hand, due to the accumulation of calcium and betel nut residue, stones are getting thicker and thicker.

Lead to gum injury, redness, suppuration, root exposure and so on. , leading to periodontal disease.

Eventually, the teeth fall off one by one or have to be pulled out.

4. Effects on oral mucosa:

Oral submucosal fibrosis and leukoplakia caused by chewing betel nut,

That is, the early stage of oral cancer, its clinical symptoms are difficulty in opening mouth, pain, numbness, whitening of oral mucosa and ulcer.

5. Effects on digestive system:

Betel nut juice scale pollutes the teeth and cheeks of black lips, which affects the appearance, damages the taste nerve and saliva secretion, hinders the digestive function, and betel nut residue stimulates the stomach wall, leading to inflammation and even perforation of the gastric mucosa.

Affect nutrient absorption, leading to malnutrition.

Chewing betel nut is closely related to oral cancer.

In Taiwan Province Province, betel nut chewing is closely related to oral cancer, and most patients with oral cancer have the habit of chewing betel nut, accounting for about 90%, especially in southern China. In addition, because chewers are used to putting betel nut between gum and buccal mucosa when chewing, buccal mucosa cancer and gingival cancer account for more than half of oral cancer in Taiwan Province Province, while the incidence of buccal mucosa cancer and gingival cancer in non-betel nut chewing area is quite low. According to the statistics of American scholars, these two types of cancers only account for about 14% of oral cancer, which shows how harmful areca nut is.

☆ How does chewing betel nut cause cancer?

There are several theories about the carcinogenic mechanism of betel nut. The first theory is that betel nut itself can cause cancer. Some researchers use animals as experimental models, and putting or smearing areca nut blocks or their extracts has proved that it can cause local tumor changes. Betel nut contains polyphenols, which will produce some carcinogenic oxygen free radicals in alkaline (mixed with red ash) environment. From 65438 to 0993, the research results published by the Institute of Dentistry of National Taiwan University showed that betel nut and Celastrus orbiculatus (or Celastrus orbiculatus) were genotoxic, mutagenic and cytotoxic, and their carcinogenesis process could be regarded as a series of genetic variations. Another research direction is that betel nut components will be nitrated when chewed in the mouth, and some of them have been proved to have strong carcinogenicity of betel nut cancer. The second theory holds that betel nut can promote the growth and expansion of cancer. Studies by foreign scholars show that betel nut can promote cancer in vitro, and feeding betel nut to rats can also promote the formation of oral cancer. 1990 Chengda Dentistry shows that betel nut chewing tablets in Taiwan Province Province can promote cancer locally, and then betel nut fiber and cold extract can promote cancer. During the period of 1993, advanced medical dentistry also found that the application of arecoline would increase the number of hamster cheek pouch cancer. All these studies show that betel nut sold in Taiwan Province Province is likely to have the ability to trigger and promote cancer growth.

Another possibility is that betel nut changed the local tissue structure, causing epithelial atrophy, submucosal collagen fiber accumulation, decreased blood flow and vitrification of submucosal tissue. Even if the patient is miserable, he will never recover from the "oral submucosal fibrosis" with normal opening, and the resistance and immunity of the patient's local tissue are greatly reduced, which is beneficial to the role of other carcinogens, thus gradually transforming into oral cancer.

In fact, as early as 1985, IARC made a comprehensive analysis of previous studies on betel nut chews, and announced that chewing betel nut chews containing tobacco or chewing betel nut at the same time has the habit of smoking, which has obvious carcinogenic effect on human body and can lead to cancer of mouth, throat and esophagus. This is supported by sufficient evidence. Worryingly, nearly 90% betel nut chewers in Taiwan Province Province have the habit of smoking at the same time. According to IARC's opinion, we can know how serious the problem is!
