摘要目的 探讨影响氟斑牙患者对托槽粘接效果.方法 选取氟斑牙为轻、中、重患者30例,分成A、B、C 3组,年龄在14～20岁的患者,观察托槽粘接效果及时间.结果 轻度氟斑牙A组中轻扫牙面组托槽脱落率明显小于牙面未磨除组;中度氟斑牙B组釉质磨除0.1 mm组托槽脱落率明显小于牙面轻磨除组;重度氟斑牙C组釉质磨除量在0.15 mm以上组托槽脱落率明显小于牙面磨除0.1 mm组.结论 氟斑牙表层釉质的磨除能改变了釉质裘面的物理性状,可提高了粘接效果.

abstractsObjective To exploring the effective of patient with the fluorosis to the bracket bonded.Methods Selected 30 cases of patient, age range from 14ys to 20ys old with the dental fluorosis. They were divided into three groups as of A,B,C based on the degrees of mild,sever,and very sever. Observe the time and effect of bracket bonded. Results In mild fluorosis patient ( A group) , the bracket off rate was less in gently grinding dental surface than in non-grinding dental surface patient. In group B, bracket off rate enamel surface grinding 0. 1 mm group was smaller than gently grinding dental surface group; In group C, grinding dental surface in > 0. 15 mm were better than grinding dental surface in 0. 1 mm patient in bracket off rate. Conclusion Grinding the enamel surface of dental fluorosis could be in changing the physical properties of the enamel surface, and enhance the adhesive effect.
