鼻咽癌放疗后为什么三年不能拔牙 王旭红 山西省肿瘤医院

鼻咽癌放疗后为什么三年不能拔牙 王旭红 山西省肿瘤医院 鼻咽癌在放疗后为什么三年内不能拔牙？这是因为鼻咽癌的患者在接受放疗后三年内由于放射线对这个唾液腺的损伤是比较重的时候，放射线可以使唾液的分泌减少，发生唾液的粘稠，唾液的酸度增加，导致细菌在唾液中繁殖更快，容易形成放射性的龋齿牙龈的红肿、流脓、牙齿槽骨的坏死流脓。如果在放疗后三年内进行拔牙，上述的症状可以诱发颌骨的骨髓炎，如果进行抗炎治疗无效的时候病情会加重，恶化。穿破皮肤形成瘘道，终日流脓流血不止，病人不能进食，可以导致长期的慢性的消耗，最后病人会死于脓毒血症或者是全身的衰竭，所以鼻咽癌放疗后的三年内是不能拔牙的。 Why can't teeth be extracted in three years after radiotherapy for nasopharyngeal carcinoma Why can't NPC extract teeth within three years after radiotherapy? This is because in the three years after radiotherapy, the damage of the salivary gland caused by radiation is relatively serious, Radiation reduces saliva production, The saliva is sticky, The acidity of saliva increases, It causes bacteria to grow faster in saliva, It is easy to form radioactive caries, redness and pus of gingiva, necrosis and pus of alveolar bone. If the tooth is extracted within three years after radiotherapy, These symptoms can induce osteomyelitis of the jaw, If the anti-inflammatory treatment is ineffective, the disease will worsen, Deterioration. Break through the skin and form a fistula, All day long, he was bleeding, The patient can't eat, It can lead to long-term chronic consumption, In the end, the patient will die of sepsis or systemic failure, Therefore, it is impossible to extract teeth in three years after radiotherapy for NPC.
