A meta-analysis was carried out to verify the overall incidence of debonding and the influence of different variables. Random effects were adopted, with a confidence interval (CI) of 95%. Twentynine studies met the eligibility criteria. The overall incidence of debonding was 2.7% (CI: 2.1-3.6%). Similar debonding rates were found when using total-etch and self-adhesive systems while a trend towards a higher debonding rate was observed for self-etch systems. Posterior teeth presented a higher incidence of debonding (3.9%) (CI: 2.5-6.0%) than anterior teeth (1.6%) (CI: 1.0-2.5%). A higher debonding incidence was found when 2 or fewer coronal walls were reported at 3.5% (CI:2.0-5.9%).
