Postoperative testing plays an important role in evaluating clinical effect of treatment of caries by filling the decayed teeth with resin composites, which mainly depends on the detection of defects at the interface between resin composites and cavity to date, without considering the internal defects of resin composites. Here, we report, for the first time, the measurement of the morphologies within resin composites by using spectral domain optical coherence tomography. Experiments were performed on the ex vivo human carious teeth after restorations, and the results showed that the tiny cracks and air bubbles within resin composites can be clearly distinguished. With features of noninvasive imaging, high resolution and real-time processing, this system may have great potential to be applied for caries as a useful clinical evaluation tool, and with that, we should pay more attention to the internal defects of resin composites in the future in order to better assess and manage the treatment.

使用谱域光学相干断层扫描检测修复后龋齿树脂复合材料的内部缺陷

术后检测对评价树脂复合材料填充龋齿治疗龋病的临床效果具有重要作用，目前主要依靠检测树脂复合材料与龋洞界面的缺陷，未考虑树脂复合材料的内部缺陷。 . 在这里，我们首次报告了使用谱域光学相干断层扫描对树脂复合材料内形态的测量。对修复后的离体人龋齿进行了实验，结果表明，树脂复合材料内的细小裂纹和气泡可以清晰地区分。该系统具有无创成像、高分辨率和实时处理的特点，作为一种有用的临床评估工具，该系统可能有很大的潜力应用于龋病，
