To compare the efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts.
Sixty-two single rooted maxillary and mandibular central incisor teeth in forty-four patients (15 males and 29 females; age range 15-32 years) were restored either with an ultrahigh molecular weight polyethylene (UHMWP) fiber post (Bondable Reinforcement Ribbon, DENSE, Ribbond, Seattle, WA, United States) or a zircon-rich glass fiber post (Snowpost, Lot H 040; Carbotech, Ganges, France). Then, direct resin composite restoration (Clearfil AP-X, Kuraray) was performed for both post systems in tooth color suitable. Patients were recalled for routine inspections at 6 mo, 1, 2 and 3 years.
The restorations were assessed during each recall evaluation according to predetermined clinical and radiographic criteria (periapical lesion; marginal leakage and integrity; color stability; surface stain and loss of retention of the post or the composite build-up material). The follow-up data showed no significant difference in these criteria between polyethylene fibre posts and zirconia-rich glass fibre posts.
The efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts were similar, suggesting that both types of fiber post can be used successfully to help retain resin composite restorations.
Core tip: The results of our study showed that both administrations were equally successful in the 36-mo clinical follow-up. Composite-zircon-dentin-post-core monoblock are clinically successful as polyethylene fiber posts. In summary, after 36 mo of follow-up observation, 62 endodontically treated central incisors with partial crown loss that had been restored with polyethylene fibre or zirconia-rich glass fibre posts and direct resin composite exhibited favourable clinical outcomes. The combined use of fibre posts and composite materials is an efficient alternative to conventional courses of treatment for endodontically treated anterior teeth.
