问题 单项选择题

某市口腔医院的一项统计结果显示,65岁至74岁老年人中,10人中就有一个全口无牙,调查结果表明,受教育程度越高的老人,全口无牙的比例越低,这说明这些老人对口腔保健比较重视,而大部分人受旧观念的影响认为人老了就应该掉牙,因此忽视了中老年人的口腔保健,使简单易治,痛苦小,治疗费用较低的龋齿,牙龈炎发展成治疗复杂,令人痛苦,治疗费用较高的牙髓病和牙周炎,如果这段文字所表述的内容是真实的,则以下哪一项也一定是真实的?

A.某些观念、卫生习惯的改变,会影响一个年老后患牙齿疾病的风险

B.如果一个人受教育的程度比较低,年老后患牙齿疾病的风险就比较大

C.定期检查,发现疾病及时治疗是老年人的预防口腔疾病有效方法

D.80岁的老人至少应有20颗功能牙,也就是20颗能够正常咀嚼食物,不松动的牙齿
