We thus studied which factors are important for caries risk in an orthodontic patient with malocclusion. The caries risk factors investigated were 1) secretion velocity of saliva, 2) pH level of saliva, 3) viscosity of saliva, 4) streptococcus mutans and 5) lactobacilli. As a result, relatively high correlations were found in caries risk factors of pH level of saliva and lactobacilli. Digital processing of photographic-slides in the lactobacilli test was the most effective method of analysis for detecting caries risk factors.}, pages = {51--58}, title = {う蝕歴と各カリエスリスク項目との関係について}, volume = {29}, year = {2003} }
