Objectives:
The objective is to evaluate the efficacy of LuxaCore, Photo Core, and Core Max II on fracture resistance of endodontically treated teeth restored with ParaPosts and fiber-reinforced composite (FRC) posts.
Materials And Methods:
Ninety extracted mandibular first premolar teeth were randomly grouped into nine different groups with ten samples in each. I-FRC posts, II-FRC with Photo Core, III-FRC with LuxaCore, IV-FRC with composite core, V-FRC with Core Max II, VI-para Post (PP), VII-PP with Luxa core, VIII-PP with photo Core, IX-PP with Core Max II were compared for fracture resistance.
Results:
The mean fracture resistance (Newton) in group I was 452± 61.5, in group II was 412.6± 42.4 (higher from group I to group V), and lower in group VI to group IX (288 to 246.5). The mean fracture resistance of group II to V was 380.1±72.1 and group VI to IX was 62.8±70.6. The difference was statistically significant (0.001).
Conclusion:
FRC posts exhibited higher fracture resistance as compared to ParaPosts, and fracture resistance was not dependent on the type of material used.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
