Purpose: This retrospective study evaluated the survival rates of postendodontic severely decayed posterior permanent teeth in young adolescents. Materials and Methods: A total of 48 teeth (patient age range: 8.8-16.9 years) restored with a Kurer post-and-core system (Anchor System, Kurer K4) were assessed. Follow-up appointments 1 to 6 years posttreatment included radiographs and a clinical examination. Results: A total of 5 teeth (10.4%) were extracted, and 13 restorations (27%) required repair. Average restoration-to-failure time was 27 months (SD 12.2 months). Conclusion: In view of these findings, clinicians should consider post-and-core restorations an alternative to extractions of endodontically treated severely damaged teeth in adolescents.
