| 目的 探讨everStick高强纤维树脂贴面修复四环素染色牙的优势。方法 选取四环素染色牙患者20例（共80颗患牙），随机分为实验组（10例）和对照组（10例），按照树脂贴面修复的牙备要求对患者上颌4颗切牙进行牙体预备，实验组和对照组分别采用everStick高强纤维树脂材料（NET型）及3M光固化复合树脂材料制作成树脂贴面，利用Kerr全酸蚀粘接系统进行粘接。贴面完成后进行6~30个月、每次间隔6个月的临床随访，采用改良Ryge贴面复查标准及牙龈指数（GI）、龈沟出血指数（SBI）、菌斑指数（PLI）作为临床检查指标，观察贴面色彩稳定性、边缘适合性、邻接边缘变色情况、继发龋及牙周组织健康状况等，评价2种材料制成贴面的上述指标之间的差异是否具有统计学意义（P<0.05）。结果 在6~30个月、每次间隔6个月的临床随访中，实验组的修复体无松动脱落，无继发龋，边缘无明显染色，色泽稳定；对照组有5只贴面出现脱落，2只出现折裂，2组差别有统计学意义（P<0.05）；2组的牙龈指数（GI）、龈沟出血指数（SBI）、菌斑指数（PLI）结果中，实验组均低于对照组，差异有统计学意义（P<0.05）。结论 相比3M复合树脂材料，everStick高强纤维树脂材料用于四环素染色牙的贴面修复具有较好的机械强度，色泽稳定，对牙龈刺激小，有利于牙周组织健康。 |

| Objective To investigate the potential of using everStick fiber-reinforced composite veneer to restore tetracycline pigmentation teeth. Materials 20 patients with 80 tetracycline pigmentation teeth were randomly assigned to experimental group and control group (10 patients in each group). We prepared maxillary incisor teeth based on the standard procedure, forged veneers with either everStick fiber-reinforced composite (experimental group)or 3M-reinforced composite (control group), and bonded veneer with tooth using the Kerr All-etching bonding system. During the next6-30-month follow-up, aesthetic restoration was examined every 6 months based on the improved Ryge standard.We used the gingival bleeding index (GI), the sulcus bleeding index (SBI) and the plaque index (PLI)to evaluate the color stability, the marginal accuracy and the physical condition of the gingival, and tested whether the two types of veneers performed differently. Results In the experimental group, veneers exhibited good margin and unchanged color with no signs of loosening, de-bonding fracture or secondary caries. In the control group, 5 veneers fell off, and 2 veneers were fractured, and the difference was statistically significant (P<0.05). The GI, the SBI and the PLI in the experimental group were significantly smaller than the control group, and this difference was statistically significant (P<0.05). Conclusions Compared with 3M-reinforced compositeveneers, veneers made of everStick fiber-reinforced composites had better mechanical strength and color stability, with less gingival irritation, and patients had better periodontal health. |
