Plaque accumulation was determined by using the plaque index of Silness and Löe on 150 crowns in 19 patients. The plaque indices for individual crowns in a quadrant were compared to the average plaque index of the quadrant in which the crowns were inserted (quadrant plaque index = 100%). This comparative study showed that Cerestore full-ceramic crowns have little soft debris retention (32%). Ceramometal crowns (90%), natural teeth (110%), cast gold restorations (148%), and acrylic resin veneer crowns (152%) have increasing plaque retention. The results indicate that ceramics are easily cleaned and exhibit low plaque retention. Increasing the area of ceramic surfaces on restorations decreases plaque retention.
通过使用西尔尼斯和勒的菌斑指数，对19名患者的150颗牙冠进行菌斑堆积测定。将一个象限中单个牙冠的菌斑指数与植入牙冠所在象限的平均菌斑指数进行比较（象限菌斑指数 = 100%）。这项对比研究表明，Cerestore全瓷牙冠的软垢附着较少（32%）。金属烤瓷牙冠（90%）、天然牙（110%）、铸造金修复体（148%）和丙烯酸树脂贴面牙冠（152%）的菌斑附着则逐渐增加。结果表明，陶瓷材料易于清洁且菌斑附着率低。增加修复体上陶瓷表面的面积可降低菌斑附着。
