[Changes in the yeast oral flora in patients in orthodontic treatment]. / Modificazioni della flora orale di lieviti nei pazienti in trattamento ortodontico.

The Authors analyzed the modifications of some components of salivary microflora (S. mutans, Lactobacillus and yeasts) induced by orthodontic treatment. This one is able to modify the oral microflora, increasing cariogenic microorganisms concentrations in plaque and saliva. Our results demonstrated a high caries risk for the subjects of the experimental group; this data suggest the need for a critical evaluation of preventive protocols applied to the orthodontic patients.
