Oral microflora among three ethnics

There are few reports on the pathogenic microorganisms that cause early childhood caries(ECC) in remote areas, and the conclusions vary. Investigating the diversity of the oral microflora communities in caries-susceptible children in areas with ethnic characteristics is necessary to comprehensively analyze the influencing factors of dental caries, explore the microbial characteristics leading to the occurrence and development of caries, and moreover, provide a theoretical basis for the etiological study of caries, to effectively control the occurrence and development of ECC.
