Item Metadata only The potential of high copper alloys as alternative materials for post-and-core application(Mahidol University. Mahidol University Library and Knowledge Center, 2004) Usanee Peungpaiboon; Somchai UrapeponPublication 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 modelItem Metadata only Development of Cu-Al-Ni alloy for dental post and core application(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Apiwat Rittapai; Somchai Urapepol; Widchaya Kanchanavasita; Kallaya SuputtamongkolGenerally, the technique used for replacement of the tooth is "posts and cores". Noble and semi-precious dental alloys have numerous excellent properties, but they are expensive and unaffordable for lots of patients. The copper-aluminum-nickel alloy... is a reasonably priced alternative, and theoretically is perceived as corrosion resistant. Therefore, this situation could potentially be a prototype to develop a base-metal alloy for dental post and core application, and generate dentistry that is morePublication 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. MATERIALS AND METHODS: Sixteen groups of experimental... be considered for a potential use as dental post and core applications. © 2014 The Korean Academy of Prosthodontics.Item Metadata only Comparison of Uniform Hazard Spectrum and Conditional Mean Spectrum in Nonlinear Response History Analysis of Tall Buildings with Post Tension Slab and Hollow Core Slab(2026-01-01) Pradittan P.; Ornthammarath T.; Pradittan P.; Mahidol Universityto show the response of the building under 10 ground motions using these methods in nonlinear response history analysis (NLRHA) in FEM software. Furthermore, this study is trying to compare the results of using the post-tension slab and hollow core slabItem Metadata only Fracture Resistance of the Crown Retained By Milled Computer-Aided Design-Computer-Aided Manufacturing Unidirectional Fiber-Reinforced Composite Post(2024-01-01) Boriboon N.; Urapepon S.; Boriboon N.; Mahidol Universitypost. 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 Core decompression and concentrated autologous bone marrow injection for treatment of osteonecrosis of the femoral head.(2012-09-01) Areesak Chotivichit; Ekkapoj Korwutthikulrangsri; Chirayu Auewarakul; Sorarid Sarirasririd; Mahidol UniversityOsteonecrosis of the femoral head is a deficiency of blood supply resulting in femoral head collapse and joint destruction. This usually found in young adults as the leading cause of hip arthroplasty. Core decompression has been reported to reduce... the bone marrow pressure for treatment of stage I and II of disease. Later, addition of concentrated bone marrow injection was proposed and reported good result. The purpose of the present study was to report the result of core decompression
