Comparison of Streptococcus mutans Concentrations in Non-banded and Banded Orthodontic Patients

Abstract

The effect of orthodontic banding on the prevalence of Streptococcus mutans in plaque was evaluated by comparisons between patients wearing bands and patients just prior to banding on the basis of treatment and/or dental caries history. Banded patients had significantly higher levels of S. mutans in plaque than did their non-banded counterparts. Regardless of banding, patients with a history of caries had significantly higher levels of S. mutans in plaque and greater numbers of S. mutans- infected sites than did caries-free patients. Caries-free banded patients had more S. mutans- infected sample sites than did the caries-free non-banded group.
