The aim of this study was to determine the periodontal status in relation to the quality of the adjacent proximal tooth surface. The gingival index (GI) and probable pocket depth (PD) were measured in 144 contra-lateral pairs of sound vs. restored and 95 contra-lateral pairs of sound vs. carious surfaces in 124 patients. The restorations studied were silver amalgams and tooth-coloured filling materials, the margins of which were supragingival or level with the gingival margins. The results showed that the GI and PD were greater for both restored and carious tooth surfaces than for the contra-lateral sound surfaces. When all the teeth were grouped together, the differences in the mean values of GI and PD were statistically significant at the P less than or equal to 0.05 level. A comparison between restored and carious (non-paired) tooth surfaces revealed higher mean values of GI and PD for the latter, which were highly significant at the P less than 0.001 level. Thus the present study shows that proximal tooth surface quality influences the health status of the adjacent periodontium.
本研究的目的是确定与相邻近中牙面质量相关的牙周状况。在124名患者中，对144对健全牙与修复牙以及95对健全牙与龋坏牙的对侧牙进行了牙龈指数（GI）和可能的牙周袋深度（PD）测量。所研究的修复体为银汞合金和牙色填充材料，其边缘位于龈上或与牙龈边缘平齐。结果显示，修复牙面和龋坏牙面的GI和PD均高于对侧的健全牙面。当所有牙齿归为一组时，GI和PD平均值的差异在P≤0.05水平具有统计学意义。修复牙面与龋坏（非配对）牙面之间的比较显示，后者的GI和PD平均值更高，在P<0.001水平具有高度显著性。因此，本研究表明近中牙面质量会影响相邻牙周组织的健康状况。
