The role of mechanical control of biofilm in the salivary pH after sucrose exposure in children with early childhood caries

Abstract This quasi-experimental study sought to investigate if the mechanical control of biofilm (3-times-a-day) modifies the saliva’s ability to buffer the oral environment after 20% sucrose rinse (SR20%) in children with early childhood caries (ECC). Here, SR20% reduced the saliva’s pH in both gr...
