氟化氨银和氟化钠涂料对乳牙龋治疗作用

Effect of silver diamine fluoride and sodium fluoride varnish in trea tment of caries of primary teeth

目的 :观察 3 8mL/L氟化氨银液和 50mg/L氟化钠涂料对乳前牙龋的治疗作用。 方法 :来自 8所幼儿园的 3 75名 3～ 5岁患有上颌前牙龋的儿童参加了该项研究 ,他们被随机分配到 5个组。各组处理分别为去腐和每年涂布 1次氟化氨银 ;每年涂布 1次氟化氨银 ;去腐和每 3个月涂布 1次氟化钠 ;每 3个月涂布 1次氟化钠 ;涂布水。结果 :2 4个月后各组儿童上颌前牙平均静止龋牙面数分别为 3 .52、3 .54、1.93、1.95和1.67(P <0 .0 0 1)。结论 :1年 1次涂布 3 8mL/L氟化氨银对乳前牙龋有治疗作用 。

AIM:To investigate the effect of silver di am ine fluoride and sodium fluoride varnish in treatment of dental caries of primar y teeth. METHODS: 375 3-5 year-old children with carious uppe r anterior teeth were randomly divided into five groups. They received removal o f soft carious tissues and annual applications of silver diamine fluoride soluti on, annual applications of silver diamine fluoride solution, removal of soft car ious tissues and applications of NaF varnish every three months, applications of NaF varnish every three months, and application of water respectively. RESULTS: The results of 24 months showed that the mean numbers of arr ested caries tooth surfaces in five groups were 3.52, 3.54, 1.93, 1.95 and 1.67 respectively (P<0.001). CONCLSUION: Annual application of silver diamine fluoride solution is effective in arresting dental caries in pri mary anterior teeth. Carious removal prior to the fluoride treatments has no sig nificant effect on their ability to arrest dental caries.
