深度楔状缺损两种修复方法的临床疗效观察

通过光固化氢氧化钙垫底后Dyract复合体修复和直接用Fuji II玻璃离子水门汀分别修复牙颈部深度楔状缺损，临床观察6个月～24个月。对二者的治疗效果进行研究分析，认为玻璃离子水门汀直接修复深度楔状缺损治疗效果优于以光固化氢氧化钙垫底用Dyract复合体修复，Fuji II玻璃离子水门汀直接充填是一种较理想的修复深度楔状缺损技术。

Two Kinds of Repair Methods for Teeth Depth of the Wedge--shaped Defect

To compare the observed light--cured calcium hydroxide bottom composite Dyract after repair and the direct use of Fuji II glass ionomer cement neck deep wedge--shaped defects in dental clinical efficacy. 178 cases of tooth neck deep wedge--shaped defect in patients with 412 teeth were randomly divided into two groups. Group 1 Fuji II glass ionomer di- rect repair. Group 2 using light--cured calcium hydroxide bottom composite Dyraet after repair. 6--24 months follow-up after, the results were significantly different after two years （P〈~0. 05 ）, six months no significant difference （P〉0. 05 ）. 2 years after the first set of edge adaptation, secondary caries and periodontal dental pulp are superior to group 2 （P〈0. 05）. Repair of glass ionomer cement direct treatment of wedge--shaped defects over the depth of light curing calcium hydroxide to bottom with Dyract complex repair, FujiII direct filling of glass ionomer cement is an ideal depth of wedge-- shaped defect repair technology.
