The purpose of this study was to examine the number of S. mutans and Lactobacillus </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>sp in children with in children’s saliva with dental caries and free caries. Twenty children attending the Paediatric Dental Clinic in </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>Airlangga University participated in our study.
