The relationships between the composition of both free smooth surface and approximal plaque and salivary composition and sugar intake assessed from a retrospective 24-hour dietary history were investigated. The inorganic phosphorus concentrations of both types of plaque collected from the permanent dentition were directly related to concentrations in stimulated whole saliva of 45 males aged 12-13 years. The calcium, inorganic phosphorus, water-soluble carbohydrate and protein concentrations of free smooth surface plaque were related to both the time since the last reported sugar intake and the amount of sugar and number of sugar intakes consumed in the previous 24 h as assessed from the retrospective diet histories of 75 females aged 14-15 years. A similar relationship with the reported time since sugar was observed for the calcium and carbohydrate concentrations in approximal plaque, but an association with the reported 24-hour sugar intake was not observed. Fewer statistically significant correlation coefficients were observed between the composition of both types of plaque and the reported sugar intake in the male subjects. The results indicate that the composition of both types of plaque are related to the composition of saliva and the time elapsed since the last sugar intake, but the relationship between the composition of plaque and sugar intake may differ between free smooth surface and approximal plaque.
研究了从回顾性24小时饮食史评估的游离光滑表面菌斑和邻面菌斑的组成与唾液组成及糖摄入量之间的关系。从12 - 13岁的45名男性恒牙采集的两种菌斑的无机磷浓度与刺激全唾液中的浓度直接相关。根据75名14 - 15岁女性的回顾性饮食史评估，游离光滑表面菌斑的钙、无机磷、水溶性碳水化合物和蛋白质浓度与上次报告的糖摄入后的时间以及前24小时摄入的糖量和糖摄入次数有关。在邻面菌斑中，钙和碳水化合物浓度与报告的自上次吃糖以来的时间存在类似关系，但未观察到与报告的24小时糖摄入量的关联。在男性受试者中，两种菌斑的组成与报告的糖摄入量之间观察到的统计学显著相关系数较少。结果表明，两种菌斑的组成与唾液组成以及自上次吃糖以来经过的时间有关，但游离光滑表面菌斑和邻面菌斑中菌斑组成与糖摄入量之间的关系可能有所不同。
