“…[ 1 ] Since, the 1990s fiber-reinforced posts have been employed more frequently to restore endodontically treated teeth that excessively lost tooth structure. Fiber reinforced posts (18-22 GPa) have a modulus of elasticity similar to the dentine (18 GPa);[ 2 ] they produce a stress field similar to that of natural teeth, thereby reducing the risk of root fractures[ 3 4 ] In addition, fiber posts showed increased incidence of repairable fracture when compared to cast dowel posts.

Introduction:To evaluate the effect of two different post space diameters and related resin cement film thicknesses on the bond strength of a polyfiber post.Materials and Methods:A total of 48 premolars were randomly divided into two according to the post space diameter: 1.1 mm and 1.5 mm. Then each group was divided into three sub-groups according to luting cement used: RelyX U100, Panavia F2.0/ED primer, Clearfil SA cement. Spirapost was then luted into the canal using luting cements. Two slices were obtained from each root specimen. Push-out tests were performed. Data was analyzed with Kruskal-Wallis and Connover post-hoc and Mann-Whitney U-test (P < 0.05).Results:Push-out bond strength was found to vary significantly according to type of adhesive system and post space diameter size (P < 0.05). The self-adhesive resin cement RelyX U100 had significantly higher bond strengths compared with the other adhesive system (P < 0.05). The self-etch adhesive system (Panavia F2.0) showed significantly lower bond strengths compared with the other systems (P < 0.05). There was a significant interaction between the luting systems and post space diameter (P < 0.05).Conclusion:The increases in post space diameter significantly reduced the bond strength of Spirapost to root dentine for both groups.

“…In another congruous study, Luthria et al , also evaluated the fracture resistance of ETT with wide MOD cavities restored with PFC resin reinforced by different types of FRCs (glass and polyethylene) ( 41 ). The results revealed that, the fracture resistance of composite restorations reinforced with glass FRCs (Interlig) was higher (600.5 N) than polyethylene FRCs (Ribbond) (514.6 N).…”

“…The results revealed that, the fracture resistance of composite restorations reinforced with glass FRCs (Interlig) was higher (600.5 N) than polyethylene FRCs (Ribbond) (514.6 N). Authors attributed the lower reinforcing efficiency of polyethylene FRC to the manually, non-uniform wetting of polyethylene FRC with unfilled resin, which negatively influenced on the adhesion of FRC to PFC resin matrix ( 41 ).…”

BackgroundFiber reinforced composite (FRC) is a promising class of material that gives clinicians alternative treatment options. There are many FRC products available in the market based on either glass or polyethylene fiber type. The aim of this study was to present a comparison between glass and polyethylene fiber reinforced composites based on available literature review.Material and MethodsA thorough literature search, with no limitation, was done up to June 2017. The range of relevant publications was surveyed using PubMed and Google Scholar. From the search results, articles related to our search terms were only considered. An assessment of these articles was done by two individuals in order to include only articles directly compare between glass and polyethylene FRCs. The search terms used were “fiber reinforced dental composites” and “glass and polyethylene fibers in dentistry”.ResultsThe search provided 276 titles. Full-text analysis was performed for 29 articles that met the inclusion criteria. Most were laboratory-based research with various test specimen designs prepared according to ISO standard or with extracted teeth and only three articles were clinical studies. Most of studies (n=23) found superior characteristics of glass FRCs over polyethylene FRCs.ConclusionsSignificant reinforcement differences between commercial glass and polyethylene fiber reinforced composites were found. Key words:Fiber reinforced composite, glass fiber, polyethylene fiber.

“…Though the use of composite resins for PERs has been routinely accepted, they are still not used in extensive restorations, especially in high stress-bearing areas, 60 as they have been shown to possess poor fracture resistance in all cavity designs. 61 This is due to the poor adhesive interface and bond strength, which is the lowest at the pulpal floor, followed by radicular dentin and the chamber wall.…”

Minimally Invasive Endodontics and Endo-endorestorative–Prosthodontic Continuum: The Right Balance?

The ultimate goal of any operative procedure is to restore the tooth to its original form and function within the arch as well as to reestablish esthetics wherever applicable. The primary objective of the endodontic therapy is the elimination of bacteria and their by-products, pulpal remnants, and debris from the root canal system. To achieve this goal, the biomechanical aspects of the tooth structure are often compromised, leading to the questionable prognosis of the restorative factor of endodontically treated teeth (ETT). The current technological advancements in the field of endodontics that preserves more natural tooth structure and adhesive dentistry that enables better restoration of the lost tooth structure, when used in the optimal way, can pave a path for the right balance between the endodontic and restorative components of teeth. This narrative review highlights the ways in which the right balance can be achieved between the two.
