| description | Background and aims. The aim was to evaluate the effect of three methods of fiber insertion on fracture resistance of
root-filled maxillary premolars in vitro.
Materials and methods. Sixty extracted human maxillary premolars received endodontic treatment followed by preparation
of mesioocclusodistal (MOD) cavities, with gingival cavosurface margin 1.5 mm coronal to the cementoenamel junction
(CEJ). Subsequently, the samples were randomly divided into four groups: no-fiber group; occlusal fiber group (fiber
was placed in the occlusal third); circumferential fiber group (fiber was placed circumferentially in the cervical third); and
dual-fiber group (occlusal and circumferential fibers). Subsequent to restoring with composite resin and thermocycling, a
compressive force was applied until fracture. Data was analyzed using one-way ANOVA and Tukey test at significance
levels of P < 0.05 and P < 0.02, respectively.
Results. Fiber placement significantly increased fracture resistance. Fracture resistance in the dual-fiber group was significantly
higher than that in the circumferential fiber group (P < 0.007); however, there were no significant differences between
the dual-fiber and occlusal fiber groups (P = 0.706). The highest favorable fracture rate was observed in the circumferential
fiber group (60%).
Conclusion. Composite resin restoration along with glass fiber in the occlusal and gingival thirds can be an acceptable
treatment option for restoring root-filled upper premolars. |
