Restoration of endodontically treated teeth with major hard tissue loss – bond strength of conventionally and adhesively luted fiber‐reinforced composite posts

Abstract

Luting system selection significantly influenced the bond strength of conventionally and adhesively luted FRCPs to bovine root canal dentin.

Effect of periodontal disease on the bond strength of fiber post cemented with different adhesive systems and resin luting agents

“…The placement of posts reduces the stress in the cervical area by directing along the post length the occlusion stress of the mouth [1,4,11,31]. Moreover, posts should be used when there is a need to provide additional retention for the core build-up [8,10,13].…”

“…A prerequisite for the use of fiber posts is their adhesive cementation, which creates a bond between the post and the root canal dentin and form a structurally and mechanically homogeneous complex. The combination of an adhesive bond to the root canal dentin with a resin core build-up allows the restoration of nonvital teeth while preserving the remaining tooth structure [3,11,13]. However, the goal is not only to achieve a high retentive bond strength of the fiber post, but also to avoid any microbiologic leakage along the root canal or post and to avoid degradation of the fiber post structure [34].…”

“…Metal alloys are generally used to fabricate post-and-core [3,6]. Prefabricated posts are divided into two groups: (1) metallic, such as titanium, palladium, gold and stainless steel alloy posts, and (2) non-metallic, such as carbon fiber, glass fiber and yttrium-stabilized zirconia-based ceramic posts [3,6,12,13].…”

Effect of a 12‐methacryloyloxy‐dodecyl‐pyridinium‐bromide–containing adhesive with different post types on the long‐term bond strength to dentin

“…Subsequently, the roots were sectioned using a double‐sided diamond disc (KG Sorensen, Barueri, SP, Brazil) and cleaved in the long axis to determine the fracture pattern after pull‐out testing. Then, the samples were analyzed using a stereomicroscope (Leica Microsystem, Wetzlar, Germany) at 40× magnification and classified according to the failure pattern in the cement–dentin interface into one of four types: adhesive (no cement on dentin surface); cohesive within the material (cement on dentin surface); cohesive within the substrate (failure in dentine); or mixed (association of adhesive and cohesive failures).…”

Choice of Endodontic Fiber Posts and its Influence on Dental Malpractice: An in vitro Evaluation

“…[13][14][15][16] Although posts are necessary to retain coronal build-up materials, they do not reinforce roots and may even weaken them through loss of radicular dentin necessitated by post space preparation, 6,17 while several studies also suggested that glass fiber posts contributed to the reinforcement and strengthening of endodontically treated teeth under full coverage crowns.…”
