This study investigated the teaching of direct resin composite restoration repair in primary teeth in undergraduate dental programs within Brazil. A questionnaire relating to this topic was developed and e-mailed to 205 undergraduate dental schools between May and September 2019. Data obtained were analyzed descriptively. The response rate was 43.4% and out of those responding schools, 82% included this topic within their curriculum. Two of the most commonly reported reasons for teaching repair of resin composite restorations were dental structure preservation (95.9%), and reduction in the risk of pulp complications (71.2%). With regard to protocol for repair, few schools (24.7%) taught mechanical roughening of the resin portion to be repaired with diamond burs. Conversely, phosphoric acid etching was recommended by 87.7% of schools and 76.7% indicated adhesive application into prepared surface. The most commonly taught material for repair was conventional resin composite. The teaching the repair of failed resin composite restorations has been established within the curriculum of undergraduate dental programs in Brazil. However, there is no consensus for the clinical protocol for repair.
