在癌症的化疗旅程中,患者往往会面临一系列的副作用，其中之一便是口腔问题，这可不是简单的口腔溃疡或口臭那么简单，而是可能威胁到患者生命健康的“隐形敌人”，为什么在化疗期间，医生会建议甚至要求患者拔除一些牙齿呢？这背后，其实是一场精心策划的“口腔保卫战”。
化疗与口腔的“不期而遇”
化疗,作为治疗癌症的一种重要手段，通过药物杀死快速分裂的癌细胞来达到治疗目的，这种“不分青红皂白”的攻击方式也会误伤到正常细胞，尤其是那些分裂速度较快的细胞，比如骨髓中的造血细胞和口腔黏膜细胞，这就导致了化疗患者常常出现口腔问题，如口腔溃疡、牙龈炎、口臭等。
拔牙：为了更长的生存之路
-
预防感染：化疗后，患者的免疫系统会受到抑制，这使得他们更容易受到感染，而口腔中的细菌、病毒等微生物在此时就可能成为“趁火打劫”的敌人，拔除一些可能引起感染的牙齿（如智齿、松动牙等），可以大大降低感染的风险。
-
减少口腔溃疡：化疗药物不仅会攻击癌细胞，还会对口腔黏膜造成损伤，引发口腔溃疡，而口腔中的牙齿，尤其是那些位于溃疡易发区域的牙齿（如智齿），在咀嚼时可能加剧黏膜的损伤，拔除这些牙齿，相当于为口腔黏膜创造了一个“避难所”，减少摩擦和刺激。
-
改善进食：化疗后，许多患者会出现味觉改变、食欲下降等问题，而口腔中的不适（如牙齿疼痛、牙龈问题）更是雪上加霜，拔除一些影响进食的牙齿，可以帮助患者更好地咀嚼食物，提高食欲，从而保证营养摄入，增强身体抵抗力。
-
减少药物副作用：某些化疗药物在经过口腔时，可能会与牙齿发生反应，导致药物失效或产生不良反应，拔除相关牙齿可以减少这种不必要的“浪费”，确保药物能够更有效地到达目标部位。
幽默一刻：拔牙也“治愈”心灵
除了上述严肃的医学原因外,拔牙在某种程度上也成了一种“心理疗法”，想象一下，面对化疗这一人生大考，患者们不仅要与体内的癌细胞作斗争，还要应对各种身体不适和心理压力，而当医生宣布“你可以不用再为这些牙齿烦恼了”时，是不是也像是在告诉他们：“你的战斗已经胜利了一半！”这种小小的胜利感，或许就是他们继续前行的动力之一。
Conclusion: The Unspoken "Battle of the Mouth" in Cancer Chemotherapy
In the journey of cancer chemotherapy, patients often encounter a range of side effects, one of which is oral issues. This is not just a simple case of canker sores or bad breath but a "hidden enemy" that can threaten their life. So, why do doctors recommend or even require patients to extract some teeth during chemotherapy? It's actually a well-planned "battle of the mouth."
Preventing Infections: Chemotherapy weakens the immune system, making patients more susceptible to infections. Teeth, especially those that are infected or loose, can become breeding grounds for bacteria and viruses. Extracting these teeth reduces the risk of infection.
Reducing Mouth Sores: Chemotherapy drugs not only attack cancer cells but also damage oral mucosa, causing mouth sores. Teeth located in areas prone to sores, such as wisdom teeth, can exacerbate the damage during chewing. Extracting these teeth creates a "safe zone" for the oral mucosa, reducing friction and irritation.
Improving Eating: Many patients experience changes in taste and decreased appetite after chemotherapy. Oral discomfort, such as tooth pain or gum problems, can further exacerbate these issues. Extracting teeth that interfere with eating helps patients chew food better, improves their appetite, and ensures adequate nutrition intake to boost their immune system.
Reducing Drug Side Effects: Certain chemotherapy drugs can react with teeth when passing through the mouth, leading to drug inefficiency or adverse reactions. Extracting relevant teeth reduces this unnecessary "waste" and ensures the drugs reach their target more effectively.
