FujiⅡ加强型玻璃离子和光固化复合树脂修复楔状缺损的临床疗效观察

[摘要] 目的 对比fuji加强型玻璃离子光固化复合树脂修复楔状缺损临床疗效,旨在为临床治疗提供理论指导依据。 方法 随机将我科2010年1月~2011年1月治疗的100例牙体楔状缺损患者分为FujiⅡ加强型玻璃离子组和光固化复合树脂组,每组各50例,比较两组的成功率及两组材料充填后失败原因。 结果 FujiⅡ组成功率虽然高于光固化复合树脂组,但差异无统计学意义,两组均无一例发生牙髓炎、牙周炎,但光固化复合树脂组密合性差,充填物脱落率高。 结论 FujiⅡ加强型玻璃离子和光固化复合树脂修复楔状缺损均具有较好的疗效,但FujiⅡ加强型玻璃离子疗效更理想,修复失败率低,值得推广和应用。

[Abstract] Objective To compare the clinical efficacy of Fuji Ⅱreinforced glass ionomer and light—cured composite resin for repairing the wedge—shaped defects. Methods In our department from January 2010 to January 2011, 100 cases dental wedge—shaped defect patients were divided into Fuji Ⅱ reinforced glass ionomer group and composite resin group, 50 cases in each, the success rate and the reasons for failure in the material filling between two groups were compared. Results FujiⅡcomposed of power although was higher than that in the control group, but the difference was not statistically significant, no case of pulpitis, periodontitis, but light—cured composite resin group had poor and high off of fillings. Conclusion FujiⅡreinforced glass ionomer and light—cured composite resin for repairing the wedge—shaped defects have good effects, but FujiⅡreinforced glass ionomer has lower repair failure rate and is worthy of promotion and application.

楔状缺损是口腔科的常见病、多发病,是发生在牙体唇颈部硬组织的慢性非龋性损伤[1],随着年龄的增加,其发生率逐渐增加。目前临床上治疗楔状缺损的充填材料有多种,其中FujiⅡ加强型玻璃离子和光固化复合树脂为常用的材料之一[2]。本研究对FujiⅡ加强型玻璃离子和光固化复合树脂的临床疗效进行分析,现报道如下。

1 资料与方法

1.1 一般资料

选择2010年1月~2011年1月在我科就诊的100例牙体楔状缺损患者,患牙均为深度楔状缺损,患牙无松动,牙周情况良好。达牙本质未穿髓,无龋坏,无充填体,均未经过治疗,随机分为FujiⅡ加强型玻璃离子和光固化复合树脂两组,FujiⅡ加强型玻璃离子组50例(56颗牙),其中男26例(52.00%),女24例(48.00%),年龄31~60岁;前牙36颗,后牙20颗。光固化复合树脂组50例(60颗牙),其中男25例(50.00%),女25例(50.00%),年龄30~59岁;前牙39颗,后牙21颗。两组患者在性别、年龄等方面比较差异无统计学意义(P > 0.05),具有可比性。

1.2 材料

FujiⅡ加强型玻璃离子水门汀(日本,富士公司)、F2000光固化复合树脂(德国,3M公司)。

1.3 方法

1.3.1 FujiⅡ加强型玻璃离子组 隔湿干燥,75%乙醇消毒30 s,气枪吹干,按材料要求粉液比例2.5:1.0(g)调拌,取病损大小所需的量,沿一侧洞壁推入充盈病损区,并用非金属充填器加压,在凝固前雕刻成型,凝固后用凡士林涂布修复体表面,如有必要24 h后用金刚石牙钻磨去多余材料,修整形态,纸砂片抛光,完成修复。

1.3.2 光固化复合树脂组 用细裂钻将边缘磨近45°的斜面,再用乙醇棉球擦拭消毒,用酸蚀剂涂布洞缘釉质壁、釉质短斜面和垫底表面,酸蚀40 s,清水清洗酸蚀剂,隔湿,吹干,涂粘接剂,光照10 s分层固化复合树脂。用金刚石牙钻修整外形,如有近髓深洞,用氢氧化钙垫底后再酸蚀。
