Publication Metadata only Photoelastic stress analysis of different prefabricated post-and-core materials(2011-10-12) Pattapon Asvanund; Steven M. Morgano; Mahidol University; The Boston University Institute for Dental Research and EducationThe purpose of this study was to investigate stress developed by a combination of a stainless steel post or a fiber-reinforced resin post with a silver amalgam core or a composite resin core. Two-dimensional photoelastic models were used to simulate... root dentin. Posts (ParaPost XT and ParaPost-FiberWhite) were cemented with a luting agent (RelyX Unicem). Silver amalgam cores and composite resin cores were fabricated on the posts. Complete crowns were fabricated and cemented on the cores. Each modelPublication Metadata only Effect of the shades of background substructures on the overall color of zirconia-based all-ceramic crowns(2013-10-22) Kallaya Suputtamongkol; Chantana Tulapornchai; Jatuphol Mamani; Wannaporn Kamchatphai; Noparat Thongpun; Mahidol Universitysubjects. Seven premolar crowns and six molar crowns were cemented onto abutments with metal post and core in the first and second group. In the third group, eight molar crowns were cemented onto abutments with a prefabricated post and composite core build...,with different core thicknesses (0.4-1 mm) were also prepared to obtain the contrast ratio of zirconia materials after veneering. RESULTS. L*, a*, and b*values of all-ceramic crowns cemented either on a metal cast post and core or on a prefabricated post didPublication Metadata only Properties of experimental copper-aluminiumnickel alloys for dental post-and-core applications(2014-01-01) Apiwat Rittapai; Somchai Urapepon; Julathep Kajornchaiyakul; Choltacha Harniratisai; Mahidol University; National Metal and Materials Technology Center (MTEC)PURPOSE: This study aimed to develop a copper-aluminium-nickel alloy which has properties comparable to that of dental alloys used for dental post and core applications with the reasonable cost.

Twenty-one extracted permanent mandibular premolars were endodontically treated and randomly divided into three groups of seven specimens. The first group received one-piece CAD-CAM unidirectional fiber-reinforced composite posts and cores (MPC...). The second group received CAD-CAM milled posts in combination with composite cores (MP). The control group used commercial fiber posts (RelyXTM fiber post). After cementing the post, core, and crown, each specimen was subjected to a compressive loadItem Metadata only Reinforcing Effect of Intraradicular Filling Materials in Simulated Immature Mandibular Premolars with Mineral Trioxide Aggregate Apical Barrier: A Weibull Analysis(2025-01-01) Opacharoensuk P.; Banomyong D.; Chotvorrarak K.; Suphanarongpun P.; Osiri S.; Opacharoensuk P.; Mahidol Universityteeth. After MTA apexification, teeth were divided into six groups: negative control (intact teeth), positive control (untreated apexified teeth), gutta-percha (GP) with AH Plus, GP with Bioceramic sealer, core, and fiber post/core. The teeth underwent... thermocycling, periodontal ligament simulation, and fracture testing. Results: Negative and positive controls exhibited the highest and lowest fracture resistance, respectively. Core and fiber post/core had hazard ratios of 4.79 and 6.23, respectivelyPublication Metadata only Effect of solvent evaporation strategies on regional bond strength of one-step self-etch adhesives to root canal dentine(2013-01-01) S. Thitthaweerat; M. Nakajima; R. M. Foxton; J. Tagami; Tokyo Medical and Dental University; Mahidol University; King's College London-S Bond Plus/Clearfil DC Core Plus; Kuraray Noritake Dental, Tokyo, Japan) were equally applied in 24 post spaces from extracted human mandibular premolars. After the adhesive application, specimens were randomly assigned into four water/solvent... were light cured, and resin core materials were placed into the post space, followed by light curing for 60 s. After water storage for 24 h, 0.6 × 0.6 mm-thick beams were prepared to measure the regional μTBS. The mode of failure was also observedPublication Metadata only Development of fibre-reinforced composite disk for computer-aided design-computer-aided manufacturing milled posts; Experimental composite disk using e-glass fibre in different fibre direction(2021-10-01) Warin Prachasujit; Somchai Urapepon; Mahidol University, Faculty of Dentistryfibre-reinforced composite disk showed the potential to be used as a CAD-CAM disk for post and core fabrication....Aims: To evaluate the flexural properties of computer-aided design-computer-aided manufacturing (CAD-CAM) milled posts fabricated from the experimental fibre-reinforced composite disks in different fibre direction, and to compare the flexuralItem Metadata only Intraradicular reinforcement of traumatized immature anterior teeth after MTA apexification(2024-01-01) Chotvorrarak K.; Danwittayakorn S.; Banomyong D.; Suksaphar W.; Chotvorrarak K.; Mahidol Universityrisk. Therefore, intra-radicular reinforcement may be necessary after MTA apexification. In vitro, intraradicular restoration with a resin composite/core build-up material or a prefabricated fiber post demonstrated better root reinforcement than root... composite/core build-up material or prefabricated fiber posts) is extremely high.
