We undertook a microbiological study, in children, of dental plaque from sound surfaces or associated with rampant caries, both black-colored and unstained. Improved selective media allowed for the enumeration of bacteria belonging to specific genera or species present in plaque samples. A nearly similar bacterial distribution was found in both types of rampant caries. Aciduric flora, Streptococcus mutans, Veillonella, and Lactobacillus predominated in plaque over the lesions, whereas extracellular polysaccharide-producing streptococci other than S. mutans, as well as Actinomyces, were more abundant in plaque from sound surfaces. However, more lactobacilli and Actinomyces were recovered from pigmented lesions than from the unstained ones. These findings suggest that the microbial flora associated with black-pigmented lesions did not strongly differ from that observed over unstained caries lesions.
我们对儿童中来自健康表面或与猖獗龋相关的牙菌斑进行了微生物学研究，这些牙菌斑既有黑色的也有未染色的。改良的选择性培养基能够对菌斑样本中存在的特定属或种的细菌进行计数。在两种类型的猖獗龋中发现了几乎相似的细菌分布。耐酸菌群、变形链球菌、韦荣氏菌和乳酸杆菌在病变上方的菌斑中占主导地位，而除变形链球菌外的产细胞外多糖链球菌以及放线菌在健康表面的菌斑中更为丰富。然而，从色素沉着病变中分离出的乳酸杆菌和放线菌比未染色病变中的更多。这些发现表明，与黑色色素沉着病变相关的微生物群与在未染色龋病变中观察到的微生物群没有很大差异。
