The integrity and thickness of Dycal linings were determined on exfoliated deciduous teeth in which proximal fillings had been placed in vivo. The teeth remained in the oral cavity for more than 18 months after placement of the restorations. The average lining thickness was found to be 114 microns. One-third of the samples showed evidence for the presence of Dycal at the gingival floor, up to the proximal tooth wall. Wash-out of the lining was observed for most teeth in which Dycal had been present near the proximal tooth wall. Incipient caries formation, associated with wash-out of the lining, was noted in a few samples. Contact between amalgam and dentine was frequently observed at the line angle, pulpal floor and axial wall.
在体内已进行邻面充填的脱落乳牙上，测定Dycal衬层的完整性和厚度。修复体放置后，这些牙齿在口腔中保留了超过18个月。发现衬层的平均厚度为114微米。三分之一的样本显示在龈缘直至邻面牙壁处有Dycal存在的迹象。在大多数Dycal存在于邻面牙壁附近的牙齿中，观察到衬层被冲洗掉。在一些样本中，注意到与衬层被冲洗掉相关的早期龋形成。在牙线角、髓底和轴壁处经常观察到汞合金与牙本质之间的接触。
