Abstract

The purpose of this study was to examine the effect of caries scoring systems on the association between caries indices and salivary counts of S. mutans in a group of ninety-eight three to five-year-old preschool children in Saskatoon, Canada. Caries was recorded using the WHO (1987) criteria and a modified scoring system(MC) in which questionable lesions (no soft walls or floor) were included as carious. Whole stimulated saliva was collected from each subject and S. mutans counts were determined (CFU/ml of saliva). Both dft(MC) = 1.03 and dfs(MC) = 1.53 were significantly different (p < .0001) from dft(WHO) = 0.69 and dfs(WHO) = 1.17, respectively. The S. mutans count was found to be significantly (p < .001) correlated with dft(MC), dfs(MC), dft(WHO) and dfs(WHO). When questionable carious lesions are included in caries indices, they appear to remain well associated with salivary S. mutans counts.

摘要

本研究的目的是在加拿大萨斯卡通市的98名3至5岁学龄前儿童中，检验龋病评分系统对龋病指数与变形链球菌唾液计数之间关联的影响。使用世界卫生组织（1987年）标准和一种改良评分系统（MC）记录龋病情况，在该改良系统中，可疑病变（无软壁或底部）被计为龋病。从每个受试者收集全刺激唾液，并测定变形链球菌计数（每毫升唾液中的菌落形成单位）。与dft（世界卫生组织标准）=0.69和dfs（世界卫生组织标准）=1.17相比，dft（MC）=1.03和dfs（MC）=1.53均有显著差异（p<0.0001）。发现变形链球菌计数与dft（MC）、dfs（MC）、dft（世界卫生组织标准）和dfs（世界卫生组织标准）显著相关（p<0.001）。当可疑龋损病变纳入龋病指数时，它们似乎仍与唾液中变形链球菌计数密切相关。
