Long-term retention and prognostic factors in repaired vertically root-fractured teeth: A retrospective cohort study

Key Points

Evaluate long-term retention of repaired vertically root-fractured teeth and identify associated prognostic factors.
Retrospective cohort study design
Analysis of teeth repaired for root fractures
Evaluation of retention outcomes over time
Idenfication of prognostic factors influencing retention
Higher retention rates observed in teeth with early intervention
Certain demographic factors linked to better retention
Mechanical stability from repair enhances long-term outcomes

Abstract

Purpose: Tooth extraction due to root fractures has recently been increasing. Preserving fractured teeth is clinically important to prevent progressive tooth loss and subsequent occlusal collapse. In this retrospective cohort study, we aimed to evaluate long-term tooth retention after root fracture repair and identify prognostic factors associated with retention outcomes.
