75%氟化鈉甘油糊劑8%氟化亞錫溶液酸性磷酸氟化鈉(APF)溶液含氟凝膠(1.5%APF凝膠)含氟涂料原理:氟與HA作用,形成氟磷灰石;沉積氟化物,促進再礦化。氟化物對軟組織無腐蝕性,不使牙變色,安全有效,前后牙均可使用。藥物治療氟化物(fluorence)藥物治療硝酸銀10%硝酸銀氨硝酸銀原理:蛋白銀沉淀

還原銀或碘化銀滲入牙釉質(zhì)牙本質(zhì),殺滅細菌,封閉病變區(qū)

對軟組織有強的腐蝕性,不可用于牙頸部齲,并使牙變黑,只用于乳牙和后牙。藥物治療硝酸銀10%硝酸銀氨硝酸銀應(yīng)用方法:用石尖磨除牙表面淺齲,暴露病變部位清潔牙面隔濕吹干涂布藥物應(yīng)用方法:用石尖磨除牙表面淺齲,暴露病變部位2.Remineralization(再礦化療法)
