Bitewings are the most effective method of detecting approximal lesions but correlation with surface integrity is poor. In this study teeth were separated using orthodontic elastic separators allowing impressions, taken in a vinyl polysiloxane impression material, to be viewed by scanning electron microscopy. Case reports demonstrate the effectiveness of this technique in assessing in vivo, and in detail, the extent of cavitation of lesions usually assessed by their radiographic image alone.
咬合翼片是检测邻面病变最有效的方法，但与表面完整性的相关性较差。在本研究中，使用正畸弹性分离器分离牙齿，以便用乙烯基聚硅氧烷印模材料制取印模，并通过扫描电子显微镜观察。病例报告证明了该技术在体内评估病变空洞程度方面的有效性，而这些病变通常仅通过影像学图像进行评估。
