对 177 名 6 - 7 岁儿童进行了调查，研究了幼儿第一恒磨牙微生物区系、萌出状态和龋齿状态之间的关系。与部分萌出的牙齿相比，完全萌出的牙齿被归类为健全且无牙菌斑的比例明显更高。与部分萌出的牙齿中以色列放线菌的数量和比例显着增加相比，完全萌出的牙齿产生了更多数量和比例的变形链球菌。逻辑回归分析显示，部分萌出的牙齿中的白斑病变与口腔链球菌、变形链球菌和唾液链球菌数量增加之间存在显着相关性，而内氏放线菌的存在与健康相关。从具有白斑病变的部分萌出的牙齿中分离出数量和比例显着更高的口腔链球菌和唾液链球菌，而从具有白点病变的完全萌出的磨牙中分离出数量和比例显着更高的变形链球菌。这项研究表明，变形链球菌以外的生物体与恒磨牙萌出过程中的龋齿发展有关。版权所有 (C) 2005 S.

The relationship between microflora, eruption status and caries status in the first permanent molar of young children was investigated in 177 children aged 6 - 7 years. A significantly greater proportion of fully erupted teeth were classified as sound and plaque-free compared to partially erupted teeth. Fully erupted teeth yielded greater numbers and proportions of mutans streptococci compared with significantly greater numbers and proportions of Actinomyces israelii in partially erupted teeth. Logistical regression analysis showed significant associations between white spot lesions in partially erupted teeth and increased numbers of Streptococcus oralis, mutans streptococci and Streptococcus salivarius whereas the presence of Actinomyces naeslundii was associated with health. Significantly greater numbers and proportions of S. oralis and S. salivarius were isolated from partially erupted teeth with white spot lesions whereas Streptococcus mutans was isolated in significantly greater numbers and proportions from fully erupted molars with white spots. This study suggests that organisms other than mutans streptococci are associated with caries development in erupting permanent molar teeth. Copyright (C) 2005 S. Karger AG, Basel.
