摘　　要：目的:观察和评价氯化镧(LaCl3)漱口水防治老年根面龋的临床效果.方法:选择63～84岁患有牙龈萎缩根面暴露的老年人222名,随机分为实验组和对照组,每组均按常规方法记录牙龈退缩数和根面龋补数,实验组每日使用一次500×10-6mmol/L的含La3+漱口水漱口,对照组使用NaCl漱口水漱口,两组均使用1个月、1年及2年后重复使用漱口水1个月,3年后复查每个老年人根面龋情况.结果:实验组根龋指数(RCI)的新增值明显低于对照组.结论:500×10-6 mmol/L的含La3+漱口水能有效地控制老年根面龋.Objective： To evaluate the clinical effects of lanthanum-contained anti-caries preparation on carious-resistance to the aged root surface , and to furnish evidence for clinical practice. Method： 222 the aged patients with gingival marginal atrophy and with root surface exposure were enrolled in study. The patients were randomized into test group and control group. The patients were administered either lanthanum-contained rinse solution in test group or saline solution in control group per day for one month at baseline every year . Clinical ts of root caries index（RCI） were analyzed at baseline 3 years. Result： The decline in clinical new parameters were significant preferable in test group than in control group. Conclusion：500×10^-6 mmol/Lanthanum -contained rinse solution per day for one month can leads to significant clinical improvement for root carious-resistance ability , especially suitable for the treatment and prevention of the aged dental root caries.
