Genotypic Diversity and Virulence Traits of Streptococcus mutans Isolated from Carious Dentin after Partial Caries Removal and Sealing

Table 1

Number of isolates and genotypes (%) of S. mutans isolated per patient from carious dentin before and after sealing.

Distinct letters show different genotypes in each patient. The designation of genotypes by letters (A, B, C, etc.) is only valid within each patient.
