  2. 口腔细菌的数量大(>10亿/mg) 种类多(400种)

  3. 细菌与龋病的关系的证据 未萌出的牙不发生龋 抗生素可减少龋病的发生和减轻其严重程度 龋损釉质和牙本质中可找到细菌

  4. 细菌与龋病的关系的证据 细菌在体外能引起龋样损害 早在19世纪，Miller就在体外，将牙、唾液和面包一起孵育，产生了牙的脱矿。如将加热后的唾液与牙、面包一起孵育，牙则不会脱矿。 无菌鼠不发生龋 由Orland等人(1955)所作的有名的无菌鼠诱龋实验所证实的。 龋病是可以传播的 1960年，Keyes等的动物实验证明龋病是可以传播的。

  5. 细菌与龋病的关系的证据 亲子之间龋的相关性研究 1995年confield报告，高龋母亲其子女患龋多 乳牙患龋率高则其后萌出的恒牙患龋率也高
