Fortification of Fractured Instrument Removal Simulated Roots Using Several Calcium Silicate-Based Materials
Abstract
Objectives: The aim of this study was to evaluate the forces
required to fracture roots obturated with different calcium silicate – based materials,
after applying a fractured instrument removal simulation.
Material
and Methods: Seventy-five
mandibular premolars were selected and decoronated. Then, all root canals were
instrumented using Reciproc system. To mimic the root canal anatomy after the
removal of a fractured instrument, each canal was enlarged with a size-3 Peeso reamer.
The specimens were distributed into experimental groups according to the
materials used for the root fortification: G1:
Negative control, G2: ProRoot
MTA, G3: Ortho MTA, G4: Biodentine, G5: Endocem MTA. Then, the teeth were embedded into acrylic blocks.
A vertical fracture test was applied, and the fracture loads were recorded. Statistical
interpretations were made (α=0.05).
Results: G2, G3, G4, and G5 showed greater fracture
resistances than G1 (P<0.05). There
was no significant difference among G2, G3, G4, and G5 (P>0.05).
Conclusions: Any of the tested materials could be chosen to
reinforce the root after the removal of a fractured instrument.
