The rate of plaque accumulation on various materials used for fixed prostheses was investigated, and the composition of plaque formed on each surface was evaluated. Enamel, metal, acrylic resin, and porcelain surfaces were studied. Amounts of plaque that formed on the teeth and fixed restorations were scored using the method of Silness and Loe. Different individuals formed plaque at different rates, and the character and quantity of the plaque was different on the various materials. In a second study, acrylic resin, metal, and porcelain crowns were made for each of 10 patients. The amount of plaque absorbed onto each material after 1, 3, and 24 hours was recorded using scanning electron microscopy. The samples of dental plaque at 24 hours on each type of crown material were collected and investigated in a CHN Analyzer 184, revealing differences in the chemical composition of plaque adsorbed onto different surfaces. The results of SEM examination and biochemical analysis are presented.
研究了用于固定修复体的各种材料上菌斑堆积的速率，并评估了在每个表面形成的菌斑的组成。对牙釉质、金属、丙烯酸树脂和瓷表面进行了研究。使用西尔尼斯和勒的方法对在牙齿和固定修复体上形成的菌斑量进行评分。不同个体形成菌斑的速率不同，并且在各种材料上菌斑的特征和数量也不同。在第二项研究中，为10名患者每人制作了丙烯酸树脂、金属和瓷冠。使用扫描电子显微镜记录了1小时、3小时和24小时后每种材料吸附的菌斑量。收集了每种类型冠材料上24小时的牙菌斑样本，并在CHN分析仪184中进行研究，揭示了吸附在不同表面的菌斑的化学成分差异。呈现了扫描电子显微镜检查和生化分析的结果。
