Incidence of new ICLs (proportion of subjects developing new lesions) · Patients undergoing fixed orthodontic treatment with fixed (multibracket) appliances, followed for development of new ICLs
About 48% of patients developed new ICLs during fixed orthodontic treatment (pooled incidence 0.48, 95% CI 0.33-0.63; very low certainty; very high heterogeneity).
1 finding from 1 review
Prevalence of ICLs (proportion of tooth surfaces affected) · Patients (permanent dentition) during or after fixed orthodontic treatment with fixed (multibracket) appliances
