| 目的 探讨氟保护漆对青少年正畸患者固定矫治后釉质脱矿发生率的影响。方法 将80例16岁以下青少年固定正畸矫治患者随机分成2组：对照组40例（721颗），对患者及家长进行口腔健康教育，不涂氟；实验组40例（742颗），除了对患者和家长宣教外，戴用固定矫治器时及正畸期间每6个月用氟保护漆处理牙面。临床观察2年，对粘接托槽的牙齿观察其脱矿程度。结果 实验组中706颗牙脱矿指数为0，出现脱矿的有36颗，脱矿率为4.85%，未出现脱矿指数大于1的患牙。对照组中有604颗牙脱矿指数为0，出现脱矿的有117颗，脱矿率为16.23%，其中脱矿指数大于1的患牙有18颗。两组间差异有统计学意义（P<0.05）。结论 固定正畸患者戴用固定矫治器时及矫治期间使用氟保护漆能有效预防正畸牙釉质脱矿。 |

| Objective To evaluate the effect of fluoride varnish on the enamel demineralization in children with fixed appliance. Methods 80 children with fixed orthodontic appliance were divided into two groups.All children and their parents were given professional prophylaxis.40 children in the secondgroup received fluoride varnish treatment,and the other 40 children did not received flour protector, and hence assigned into the first/control group. White spot incidence in all children was evaluated during a 2-year period of time. Results The index of white spot incidence was 16.23% and 4.85% in the first and second group, respectively, and the difference is statistically different. Conclusion fluoride varnish can be used effectively to prevent enamel demineralization in orthodontics. |
