[The microbial colonization of the dentin close to the pulp in the permanent teeth following deep caries therapy].
In a clinical microbiological study the microflora of cavity floors in 41 permanent teeth was investigated after several month of caries excavation and with or without Calxyl application on hard dentine prior sealing with zincphosphatecementum and amalgam. The cavity floors were only lowly infected. Actinomycetes or acidogenic and aciduric streptococci and lactobacilli dominated in the CFU. After application of Calxyl actinomycetes (A. israelii) were found 3-fold more frequently in the remaining population than streptococci (S. mutans) and lactobacilli. Without application of Calxyl their ratio was 1:1. S. mutans seems to be important for the carious progression in dentin.
