目的：评价FUJIⅡ化学固化型玻璃离子水门汀用于后牙邻面洞龈壁充填的临床疗效。方法选择后牙邻面龋患者107名，共156颗患牙，按照要求预备窝洞，邻面洞的龈壁均位于龈下≥1mm处，将患牙随机平分为两组，实验组先用FUJI Ⅱ化学固化型玻璃离子水门汀充填邻面洞达距离面洞缘至少2mm处，然后用3M复合树脂充填余留窝洞；对照组中邻、面洞均采用复合树脂充填（深窝洞先用玻璃离子常规垫底）。术后6、12个月进行复查，分别对充填物洞缘裂隙、充填物龈方继发龋及充填物完整性等情况进行评价。结果两组患牙充填物在术后6个月后的脱落率、边缘裂隙率以及龈方继发龋的发生率均无显著差异；12月后对照组充填物的脱落率、边缘裂隙率、龈方继发龋的发生率均显著高于实验组（P<0.05）；6个月及12个月时，实验组充填物的失败率均明显低于对照组（P<0.05）。结论而至FUJIⅡ化学固化型玻璃离子水门汀用于邻面洞龈壁充填有利于增加充填物的密合性，减少继发龋的发生，降低充填物的脱落率，从而改善其临床疗效。

Objectives To observe the clinical effect of FUJI Ⅱglass ionomer cement on the gingival wall fillings in the proximal-occlussal cavity of posterior teeth. Methods 156 posterior teeth in 107 patients suffered from approximal caries were selected. All teeth were prepared according to the requirements of proximal-occlussal cavities in which the gingival walls were located sub-gingival areas more than or equal to 1mm .The teeth were randomly divided into two groups, the first group of teeth was filled with Fuji II glass ionomer cement onto the gingival walls at least 2mm from occlussal surface, then was filled with composite resin into the remaining cavities. The second group of teeth was filled with composite resin into the whole cavities (deep cavities were routinely based with a little glass ionomer cement first ). After 6 and 12 months, all teeth were re-examinated about the fissures around the fillings, the recurrent carries at the gingival walls and the integrity of the fillings. Results There was no significant difference between two groups under the condition of the fillings after 6 months. The incidence rate of fissures, secondary caries and expulsion rate of the fillings in the second group were significantly higher than those in the first group (P<0.05). The filling failure rate of first group was significantly lower than the second group (P<0.05) after 6 months and 12 months. Conclusion Fuji II glass ionomer used to fill gingival wall in the proximal-occlussal cavity was conducive to increase adhesion of filling, reduce the occurrence of secondary caries and expulsion rate of fillings, so as to improve the clinical curative effect of composite resin restoration in the proximal-occlussal cavity of posterior teeth.
