Abstract Crown-root fractures in primary teeth are rare, with a wide variation of patterns that make diagnosis and treatment difficult. The aim of this study was to present a case series of crown-root fractures in primary teeth of children who attended a reference center. The study followed 28 cases of crown-root fractures in 26 children, representing 4% of the total number of attendees over 11 years of reference service at the Universidade Federal de Pelotas, Pelotas, Brazil. In most cases, the maxillary central incisors (85.7%) were involved. In the crown, 57.1% of the cases had a simple line of fracture, and 42.9% had multiple lines. Simple lines predominated in the root (89.3%). In cases with simple fracture lines in the crown, 37.6% underwent a total extraction, 31.2% required a partial extraction and 31.2% underwent pulpectomy. In most teeth with multiple lines of fractures in the crown, total extraction was performed (91.7%) All cases were followed-up until the eruption of the permanent successor tooth, and all patients had favorable outcomes.
