[摘要] 目的 比较渗透性树脂和氟漆治疗正畸后牙面脱矿的治疗效果。 方法 以本院2011年5月~2014年5月收治的正畸治疗后牙面脱矿患者114例作为研究对象,将其随机分为两组。A组应用渗透性树脂进行治疗,B组应用氟漆进行治疗,比较两组治疗前后的牙面脱矿颜色稳定情况。 结果 两组治疗前的白垩斑颜色稳定评分比较,差异无统计学意义(P>0.05),两组治疗后的白垩斑颜色稳定评分与治疗前比较,差异有统计学意义(P<0.05);A组治疗后的白垩斑颜色稳定评分明显高于B组,差异有统计学意义(P<0.05)。 结论 与氟漆治疗相比,渗透性树脂治疗正畸后牙面脱矿的效果更好,患者的白垩斑颜色稳定状况更佳,同时可一次性完成治疗,更加简便、快捷,提高了牙齿美观性,临床价值高,值得进一步推广应用。

[Abstract] Objective To compare the therapeutic effect of permeable resin and fluorine paint treating demineralization after orthodontic treatment of the tooth surface. Methods 114 patients with demineralization after orthodontic treatment of the tooth surface treated in our hospital from May 2011 to 2014 May were selected as the study objects,and they were divided into the two groups.The group A was treated with permeable resin,the group B was treated with fluorine paint,color stability of demineralization of the tooth surface before and after treatment in the two groups was compared. Results There was no statistical difference of color stability score of chalky spot before treatment in the two groups (P>0.05),there was a statistical difference of color stability score of chalky spot in the two groups after treatment compared with before treatment (P<0.05),color stability score of chalky spot in the group A was higher than that in the group B,and there was a statistical difference (P<0.05). Conclusion Compared with fluorine paint treatment,permeable resin treating demineralization after orthodontic treatment of the tooth surface has better effect,color stability of chalky spot of patients is better,at the same time,it can complete treatment once,and it is simple and quick.It improve the aesthetic property of the teeth with high clinical value,it is worthy of further promotion and application.

早期牙釉质脱矿是固定矫治中常见的一种不良现象,以牙釉质呈现白垩色改变为主要表现,严重时会引起牙体缺损[1]。白垩斑的出现会影响患者牙齿的美观性,不仅对外观产生一定的消极影响,甚至可能对牙体硬组织造成不可逆破坏。相关研究显示,临床正畸治疗后至少1颗牙齿发生釉质白垩斑的概率在20%左右[2],积极予以预防及防治非常重要。本研究以本院收治的正畸治疗后牙面脱矿患者作为研究对象,比较渗透性树脂和氟漆治疗正畸后牙面脱矿的效果。
1 资料与方法
1.1 一般资料
选取本院2011年5月~2014年5月收治的正畸治疗后牙面脱矿患者114例作为研究对象,按照随机数字表法将患者分为两组。A组58例(患牙共65颗),男32例,女26例,年龄12~26岁,平均(16.8±4.7)岁,平均白垩斑牙齿(1.1±0.3)颗。B组56例(患牙共66颗),男30例,女26例,年龄13~24岁,平均(16.5±4.1)岁,平均白垩斑牙齿(1.2±0.3)颗。两组患者的年龄、性别比例、平均白垩斑牙齿数目等比较差异无统计学意义(P>0.05),具有可比性。
1.2 纳入标准
①患者正畸治疗已经结束;②至少1颗上颌切牙出现牙面脱矿情况;③使用探针可钩住白垩色斑或感觉粗糙。
1.3 排除标准
①依从性差者;②白垩斑出现明显龋洞者;③接受正畸治疗后又接受过与本次治疗类似矿化治疗者;④患者口内存在四环素牙、氟斑牙及釉质发育不全者。
1.4 治疗方法
A组应用渗透性树脂(德国DMG公司,Icon 渗透性树脂)进行治疗:清洁患者牙后将楔子置于邻间隙。涂布Icon酸蚀剂于白垩斑区,注意要超出病损区2 mm,30 s后予以冲洗冲并吹干,然后涂布Icon干燥剂于白垩斑区并吹干。之后于已酸蚀牙面上涂布渗透性树脂,等待3 min后用棉球将多余材料去除并予以光照,时间在40 s左右。重复将Icon渗透性树脂涂布于已酸蚀牙面上,等待1 min后予以40 s光照,进行打磨及抛光,嘱患者使用含氟牙膏并注意口腔卫生。B组应用氟漆(瑞士伟瓦登特公司)进行治疗:清洁患者患牙后冲洗并隔湿,用棉球擦干。涂布0.4 ml 5%(体积分数)氟保护漆患牙,凝固1 min即可。治疗完成后45 min内不可进食与漱口,治疗期间保持口腔清洁,使用含氟牙膏,间隔1个月复诊并再次治疗,治疗次数视患者的实际情况确定。
