Degree of conversion of resin composite cured by light through a translucent fiber posts
PURPOSE This study evaluated the depth of cure of resin composite cured by light through a translucent fiber post. MATERIALS AND METHODS The opaque plastic tubes in various lengths of 2, 4, 6, 8, 10, 12, 14 mm. were filled with resin composite in which two different translucent fiber posts were inserted into the center and photo-polymerized for 40 seconds. The degree of conversion of the cure...
متن کاملEffect of different adhesion strategies on push-out bond strength of fiber reinforced composite posts
The aim of this study was to compare the bond strength of translucent fiber posts to root dentin, cemented with 4 adhesion strategies. Forty eight (48) sound human central incisors were decoronated and divided into 4 groups: Etch-and-rinse group, two-step self-etch group, one-step self-etch group, and self-adhesive resin cement group. The adhesion between the post and root canal walls was asses...
متن کاملJürgen Manhart presents a clinical case using fiberglass reinforced composite endodontic posts Fiberglass reinforced composite endodontic posts
The prosthetic treatment of seriously damaged, endodonticallytreated teeth often require an endodontic post as an additional retention element for core build-up prior to crown restoration. In addition to metal-based posts and zirconia-based ceramic posts, fiber-reinforced composite posts have recently become a center of interest for dentists and science. In the past it was commonly accepted tha...
متن کاملFracture resistance of permanent anterior incisors using fiber-reinforced composite posts.
This in vitro study investigated whether permanent anterior incisors that are endodontically treated with cemented fiber-reinforced composite (FRC) posts without additional canal preparation can potentially increase the resistance to fracture and thus reduce the rate of clinical failure in root canals. Extracted human permanent maxillary central incisors (n = 120) were randomly assigned to 2 ex...
متن کاملMicrohardness of dual-polymerizing resin cements and foundation composite resins for luting fiber-reinforced posts
Statement of problem. The optimal luting material for fiber-reinforced posts, to ensure the longevity of foundation restorations, remains undetermined. Purpose. The purpose of this study was to evaluate the suitability of 3 dual-polymerizing resin cements (DRCs) and 2 dual-polymerizing foundation composite resins (DFCRs) for luting fiber-reinforced posts by assessing their Knoop hardness number...
