本研究采用立体显微镜和扫描共聚焦激光显微镜（SCLM）观察可流动复合材料修复体周围的牙釉质微裂纹。研究了聚合缩水率、复合材料的迁移率和充填后抛光时间对釉质边缘微裂纹发生率的影响。充填后立即抛光修复体，所有复合修复体均出现牙釉质微裂纹。牙釉质微裂纹分布与牙洞边缘近似平行，位于距修复牙洞边缘0.01 ~ 0.3 mm处。常规混合复合材料修复体的牙釉质微裂纹发生率高于流动复合材料修复体，并且在充填后15分钟抛光（与充填后24小时相比）。
In this study, enamel micro-cracks produced around flowable composite restorations were observed using a stereomicroscope and a scanning confocal laser microscope (SCLM). The effects of polymerization shrinkage, mobility of composite and polishing period after filling on the incidence of marginal enamel micro-cracks were examined. Enamel micro-cracks were observed on all of the composite restorations when the restoration was polished immediately after filling. Enamel micro-cracks distributed approximately parallel to the cavity margin and located 0.01-0.3 mm from the restored cavity margin. The occurrence of enamel micro-cracks was higher in conventional hybrid composite restorations than in flowable composites, and when polished 15 minutes after filling (as compared to 24 hours after filling).
