在口腔内科临床上,防龋,治疗初龋,窝洞消毒,安抚镇痛药物,盖髓剂,牙髓失活剂,干髓剂,根管消毒剂,碘甘油等较为常用。一、防龋药物2%氟化钠溶液作用:氟是机体维持正常生命活动所必须的微量元素之一,也是牙齿和骨的正常钙化所必须的。由于牙齿硬组织中含有氢氧磷灰石易溶于酸,性质不稳定,易与很多元素合成其他磷灰石。因为氟化物与牙釉质等硬组织有强烈的亲和作用,所以当牙齿表面涂氟后,氟渗入矛齿硬组织内,氢氧磷灰石就变成难溶于酸的氟磷灰石,从而增加牙齿的抗酸
In oral medicine clinical, caries prevention, early caries treatment, cavity disinfection, appease the analgesic drugs, pulp capping agent, pulp deactivator, dry pulp, root canal disinfectant, iodine glycerol, etc. are more commonly used. First, the anti-caries drugs 2% sodium fluoride solution: Fluoride is one of the trace elements necessary for the body to maintain normal life activities, but also the normal calcification of the teeth and bones are necessary. As the hard tissue contains hydroxyapatite soluble in acid, unstable nature, easy synthesis of many other elements and apatite. Because fluoride and enamel and other hard tissue has a strong affinity, so when the tooth surface fluoride, fluoride penetrate into the spear hard tissue, hydroxyapatite becomes difficult to dissolve in acid fluoride apatite, Thus increasing the tooth's acid resistance
