摘要
目的:观察高强度流动树脂修复后牙邻面洞的临床疗效。方法:选择106例患者的132个深龋邻面洞为研究对象,并按就诊顺序将其随机分为实验组(n=68)和对照组(n=64);实验组以流动树脂衬洞再用高强度流动树脂充填;对照组以玻璃离子水门汀垫底,再用复合树脂充填的"三明治"技术进行修复;修复后1年采用改良的USPHS/Ryge临床修复体质量评估系统分别评价其修复效果,并对数据进行统计学分析。结果:实验组和对照组1年复诊牙数分别为65(95.6%)和59(92.2%)修复1年后实验组在修复体边缘着色和术后敏感方面的成功率分别为98.5%和100%,均高于对照组的89.8%和91.5%,差异均有统计学意义(P<0.05);而在修复体完整性和继发龋方面,两组的成功率均无统计学差异(P>0.05)。结论:采用流动树脂垫衬加高强度流动树脂充填后牙邻面洞可取得理想的临床修复效果。
AIM： To observe the clinical effect of high-intensity flowable composite in the restoration of posterior Class II cavity. METHODS： 132 teeth with posterior Class II deep cavity from 106 patients were included. The teeth were randomly divided into experiment group （ n = 68 ） and control group （ n = 64）. The teeth in experiment group were restored with high-intenSity flowable composite after lined with flowable composite, those in control group with glass ionomer/hybrid composite sandwich technique. The modified USPHS/Ryge criteria were used to evaluate the treatment effects after 1 year. SPSS 12.0 software package was used for statistical analysis. RESULTS： 65 teeth （95.6%） in experiment group and 59 （92.2%）in control group were followed - up for 1 year. The success rate of marginal discoloration in experimental and control groups was 98.5% and 89.8% resoectively （P 〈 0.05 ）. No postopera- tive sensitivity case was found in experiment group, while 5 teeth in control group showed postoperative sensitivity （P 〈 0.05 ）. Integrity of the restorations in experiment and control groups was 98.5% and 96.6% （ P 〉 0.05 ）, and noneseeondary caries occurrence 100% and 98.3% （ P 〉 0.05 ）, respectively. CONCLUSION： High-intensity flowable composite is more effective for restoration of posterior Class II cavities than glass ionomer/hybrid composite.
