摘要
目的观察氟化物对固定正畸治疗后牙面颜色的影响。方法 2017年8月收集40颗离体前磨牙,采用随机数表法分为A组、B组、C组和D组,每组10颗离体牙。A组为空白对照组,不处理牙齿; B组为托槽粘接组; C组为托槽粘接、涂氟组;D组为涂氟组。粘接托槽前对牙冠颊面中心点色度值进行测定,1个月后去除B、C组托槽,采用同一种方法去除牙冠表面粘接剂,抛光牙面,进行第2次色度值测定,计算每颗牙齿的△E*值,使用SPSS17. 0统计软件进行数据分析。结果 B、C组离体前磨牙颜色明显改变,差异均有统计学意义(P <0. 05);而C组离体前磨牙颜色改变明显小于B组,差异有统计学意义(P <0. 05)。结论固定正畸治疗对牙面颜色具有一定影响,而氟化物的应用可能降低固定正畸治疗对牙面颜色改变的影响,可在临床上推广使用。
Objective To observe the effect of fluoride on dental surface color after fixed orthodontic treatment.Methods Forty separated premolar teeth were collected in August 2017 and divided into the group A,B,C and D by adopting the random number table method.The group A was the blank control group without treating the teeth;the group B was the brackets bonding group;the group C was the brackets bonding+fluoride coating group;the group D was the fluoride coating group.The chromatic values of central point in dental crown buccal surface of all these teeth were detected before bracket bonding.After one mouth,the brackets in the group B and C were removed,the crown surface adhisive was removed by using the same method and the dental surface was polished.The chromatic values of all these teeth were detected again.The△E*value of each tooth was calculated and the data analysis was performed by using the SPSS17.0 statistical software.Results The color of separated separated premolar teeth in the group B and C was significantly changed,and the difference was statistically significant(P<0.05);while which in the group C was smaller than that in the group B,and the difference was statistically significant(P<0.05).Conclusion Fixed orthodontic treatment has a certain effect on the dental surface color,while the fluoride application may decrease the impact of fixed orthodontic treatment on the dental surface color,which can be promoted and applied in clinic.
