摘要：

背景：传统的细小窝沟龋修复需要按Ⅰ类洞形进行预备，对牙体组织破坏较多。
目的：评价流动纳米树脂微创修复细小窝沟龋的临床效果。
方法：选择14~30岁磨牙有窝沟龋且对侧同名牙或邻牙也有窝沟龋患者167例，在一侧磨牙牙合面窝沟龋去除龋坏牙体组织后，采用Adper Single Bond 2全酸蚀黏结技术，用Filtek TM Z350流动纳米树脂充填整个微创窝洞作为实验组，对侧同名牙或邻牙窝沟龋用同一公司生产的Filtek TM Z350纳米树脂充填作对照。
结果与结论：随访2年后发现实验组Z350流动纳米树脂填充体保留率高，边缘完整性好，边缘着色率低，树脂保留率、边缘完整性及边缘着色率高于对照组(P < 0.05)。提示Filtek TM Z350流动纳米树脂微创窝沟充填可有效修复细小窝沟龋。

Abstract:

BACKGROUND: The traditional treatment for early pit and fissure caries on permanent teeth is to remove caries tissue and prepare the cavity according to class Ⅰ, but which will cause the excessive loss of tooth substance.
OBJECTIVE: To review the clinical effect of flowable nano-composite resin on repairing early pit and fissure caries with minimally invasive dentistry technique.
METHODS: A total of 206 permanent molars with occlusal pit and fissure caries in 167 patients who aged from 14 to 30 years were included. After unilateral cariated tissue had been removed, the cavity was treated with Adper Single Bond 2 total-etching adhesive method, and the whole cavity was filled with Filtek TM Z350 flowable nano-composite resin with minimally invasive dentistry technique and as experimental group. The opposite or adjacent teeth with similar caries in the same patients were treated with Filtek TM Z350 nano-resin as control group.
RESULTS AND CONCLUSION: All the patients were followed up for 2 years. In the experimental group, the Filtek TM Z350 flowable nano-composite resin exhibited higher retention rate, better marginal integrity and lower marginal discoloration than those of the control group (P < 0.05). These findings suggest that Filtek TM Z350 flowable nano-composite resin can effectively repair early pit and fissure caries with minimally invasive dentistry technique.
