摘要：

目的 观察不同的楔状缺损充填材料对患牙龈上菌斑和龈沟液内微生物滞留的影响。方法 将57例单侧上颌第一前磨牙楔状缺损患者随机分为三组，分别采用树脂改性玻璃离子水门汀（RMGI组，n=19）、聚羧酸改性复合树脂（PMCR组，n=20）和光固化复合树脂（CR组，n=18）进行修复。分别于修复前和修复后3个月和6个月时，对各组患牙充填物表面菌斑内变形链球菌、黏性放线菌及龈沟液内革兰阳性（G＋）厌氧杆菌和革兰阴性（G－）厌氧杆菌进行菌落计数，以自身对侧同名牙作为对照组。结果 修复前，RMGI组、PMCR组和CR组与相应对照组的龈上菌斑和龈沟液中菌落计数比较，差异均无统计学意义（P>0.05）。修复后3个月和6个月， RMGI组治疗后龈上菌斑内黏性放线菌菌落计数以及CR组龈沟液内G－厌氧杆菌菌落计数均较其相应对照组显著增多，差异有统计学意义（P<0.05）。结论 RMGI和CR修复楔状缺损后对患牙龈上菌斑和龈沟液内微生物滞留有一定的负面影响；提示以PMCR修复楔状缺损，在抗龋性和减少牙周组织损伤方面更具优势。

Abstract:

Objective To evaluate the effects of different dental filling materials in wedge-shaped defect restorations on microbial colonization in supragingival plaque and gingival crevicular fluid. Methods Fifty-seven patients with wedge-shaped defect of maxilla first premolars were selected, and were randomly filled with resin-modified glass ionomer (RMGI group, n=19), polyacid-modified composite resin (PMCR group, n=20) and composite resin (CR group, n=18) for restorations. The numbers of colonies of Streptococci mutans and Actinomyces viscosus in supragingival plaque and anaerobic Gram-positive （G＋）rod bacillus and anaerobic Gram-nagative （G－）rod bacillus in gingival crevicular fluid were recorded before restorations and 3 months and 6 months after restorations, respectively. The contralateral corresponding teeth were served as controls. Results There was no significant difference in the numbers of colonies among RMGI group, PMCR group, CR group and control groups before restorations (P>0.05). The number of colony of Actinomyces viscosus in supragingival plaque in RMGI group and that of anaerobic G＋ rod bacillus in gingival crevicular fluid in CR group were significantly larger than those in control groups 3 months and 6 months after restorations （P<0.05）. Conclusion RMGI and CR for wedge-shaped defect restorations may have adverse effects on microbial colonization in supragingival plaque and gingival crevicular fluid, while PMCR has advantages in anti-caries and reducing periodontal tissue injury in wedge-shaped defect restorations.
