Abstract: INTRODUCTION: Fragment reattachment has been suggested as an interim emergent treatment modality for crown root fractures of permanent incisors.However, they may re-fracture leading to fragment dislodgement, even with in the acute phase.Hence, this in vitro study aimed to compare the efficacy of three management protocols of re-fracture of teeth with uncomplicated crown root fractures.MATERIAL and METHODS: Sixty mandibular bovine incisor teeth were selected and were fractured to simulate uncomplicated crown root fracture.Fragments were rehydrated and reattached as per the etching-bonding protocol and stored in artificial saliva.They were refractured and randomly allocated to three groups for rebonding: Group-I(reattachment without rehydration), Group-II-(rehydration and reattachment), and Group-III-(restoration using composite).Universal testing machine was used to evaluate the force required to fracture them.RESULTS: Group III showed the highest mean force (338.95±81.94N,95%CI-300.60,377.30), followed by Group II (255.56±58.19N,95%CI-198.32,252.79).The lowest value of force required to fracture was observed in Group I (141.76±60.16N,95% CI-113.60,169.92).CONCLUSION: The force required for fracture was greater in the teeth where composite restoration was done instead of re-bonding of dislodged crown-root fragment.Among the reattachment groups, the force required to fracture was greater when rehydration was performed.
