我们在儿童中进行了一项微生物研究，研究对象是健康表面或与猖獗龋相关的牙菌斑，包括黑色和未染色的牙菌斑。改进的选择性培养基允许对菌斑样品中存在的属于特定属或种的细菌进行计数。在两种类型的猖獗性龋中发现了几乎相似的细菌分布。在病变斑块中以耐酸植物群、变形链球菌、韦荣氏球菌和乳杆菌为主，而产胞外多糖的链球菌除外。变形菌和放线菌在健康表面的菌斑中更丰富。然而，更多的乳酸杆菌和放线菌回收色素病变比未染色的。这些发现表明，与黑色色素病变相关的微生物植物群与未染色的龋齿病变没有明显差异。
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.
