Publication Metadata only Survival Rates from Fracture of Endodontically Treated Premolars Restored with Full-coverage Crowns or Direct Resin Composite Restorations: A Retrospective Study(2018-02-01) Warattama Suksaphar; Danuchit Banomyong; Titalee Jirathanyanatt; Yaowaluk Ngoenwiwatkul; Mahidol University© 2017 American Association of Endodontists Introduction: The aim of the present study was to compare the survival rates against fracture of premolar endodontically treated teeth (ETT) restored with resin composite or crowns and to identify risk... factors associated with the fracture. Methods: Data from dental records and radiographs of premolar ETT with postendodontic restorations (ie, resin composite or crowns) were collected between 2012 and 2016 and selected following selected inclusionPublication Metadata only Endodontically treated posterior teeth restored with or without crown restorations: A 5-year retrospective study of survival rates from fracture(2019-11-01) Titalee Jirathanyanatt; Warattama Suksaphar; Danuchit Banomyong; Yaowaluk Ngoenwiwatkul; Rangsit University; Mahidol University© 2019 John Wiley & Sons Australia, Ltd. AIM: The aim of the present study was to investigate survival rates from fracture of endodontically treated posterior teeth (ETT) restored with or without crowns with recall periods of up to 5 years.... METHODS: ETT with single-unit crown or resin composite restorations were studied based on the inclusion criteria. Restoration, tooth structure loss, adjacent teeth, fracture, and restorability were recorded. Survival rates from fracture were calculatedItem Metadata only Fracture resistance of CAD/CAM blocks cemented on dentin using different cementation strategies(2023-01-01) Anuntasainont M.; Po-Ngam N.; Lührs A.K.; Neoh S.P.; Pongprueksa P.; Mahidol UniversityPurpose: To determine whether the fracture resistance of computer-aided design/computer-aided manufacturing (CAD/ CAM) resin-based composites and polymer-infiltrated ceramic network materials cemented on dentin is influenced by the restoration... machine until fracture. The fracture resistance (N) of RBC and PICN was separately analyzed using two-way ANOVA and Tukey’s post-hoc test (α = 0.05). Results: The fracture resistance of each material was significantly influenced by the material thicknessPublication Metadata only Fracture resistance, gap and void formation in root-filled mandibular molars restored with bulk-fill resin composites and glass-ionomer cement base(2019-11-01) Nathamon Thongbai-On; Kanet Chotvorrarak; Danuchit Banomyong; Michael F. Burrow; Sittichoke Osiri; Nattha Pattaravisitsate; Mahidol University; The University of Hong Kong© 2019 John Wiley & Sons Australia, Ltd. AIM: To evaluate fracture resistance and gap/void presence of root-filled mandibular molars restored with 2 bulk-fill and 1 conventional resin composites, with or without a glass-ionomer cement (GIC) base... as negative and positive controls. Fracture load (N) was determined using a universal testing machine. RESULTS: No significant difference in fracture resistance or gap/void formation was found among the 3 resin composites. GIC-base groups revealedItem Metadata only Fracture resistance of posterior teeth restored by lithium silicate-based and hybrid ceramic partial coverage restorations with different preparation designs: a scoping review(2026-12-01) Sirikatitham N.; Kukiattrakoon B.; Sattabanasuk V.; Ratanasathien K.; Ruengrungsom C.; Sirikatitham N.; Mahidol UniversityBackground: Ceramic partial coverage restorations (PCRs) are minimally invasive treatment options for complex tooth damage. This study aimed to review the fracture resistance and fracture patterns of non-endodontically treated posterior teeth... to search for specific key terms according to the PRISMA diagram. Finally, 34 articles were included for analysis. The fracture resistance and fracture patterns were summarized, and RoBDEMAT was used to assess the risk of bias. Results: With ≥ 1 mmPublication Metadata only The effect of base materials with different elastic moduli on the fracture loads of machinable ceramic inlays(2006-01-01) Sasithorn Banditmahakun; Watcharaporn Kuphasuk; Widchaya Kanchanavasita; Chotiros Kuphasuk; Health Promotion Center Region 11; Mahidol University;This study investigated the effect of two base materials with different elastic moduli (F2000 and Vitrebond) on the fracture load of machinable ceramic inlays. Standardized MOD cavities were prepared in 18 human maxillary first or second premolars... to fracture testing in a universal testing machine using a crosshead speed of 0.5 mm/minute. The static transverse elastic moduli of base materials were measured using a three-point bending test. The mean fracture loads and standard deviations of the CerecPublication Metadata only Clear Sinus Sign on Head CT Scan: Reliable Criterion to Exclude Paranasal Sinus Fracture(2020-01-01) Suwalai Koedwut; Rathachai Kaewlai; Thanwa Sudsang; Kidakorn Kiranantawat; Sirote Wongwaisayawan; Faculty of Medicine, Ramathibodi Hospital, Mahidol University© 2020 Purpose: The clear sinus sign has been described in facial computed tomography (CT) as an indication of the absence of fluid in the paranasal sinuses. It is a highly reliable criterion to exclude fracture involving the paranasal sinus wall.... Very scarce data on this sign on head CT scan is currently available. We conducted the present study to assess the usefulness of the clear sinus sign on head CT scan to exclude paranasal sinus fracture. Materials and Methods: A retrospective crossItem Metadata only Effect of connector configuration on the fracture load in conventional and translucent zirconia three-unit fixed dental prostheses(2023-01-01) Subsomboon C.; Urapepon S.; Mahidol UniversityPURPOSE. The purpose of this study was to determine the effect of the connector configuration on the fracture load in conventional and translucent zirconia of three-unit fixed dental prostheses (FDPs). MATERIALS AND METHODS. Six different three-unit.... Fracture loads of 3Y-TZP (2740.6 ± 469.2 and 2718.7 ± 339.0 N for size 4 x 2.25 mm and 3 x 3 mm, respectively) were significantly higher than those of 4Y-TZP (1868.3 ± 281.6 and 1663.6 ± 372.7 N, respectively) and 5Y-TZP (1588.0 ± 255.0 and 1559.1 ± 110.0 NPublication Metadata only Comparison of the Effects of Intraradicular Materials on the Incidence of Fatal Root Fracture in Immature Teeth Treated with Mineral Trioxide Aggregate Apexification: A Retrospective Study(2019-08-01) Supatra Danwittayakorn; Danuchit Banomyong; Lalida Ongchavalit; Yaowaluk Ngoenwiwatkul; Patcharin Porkaew; Bangkok Hospital Medical Center; Mahidol University© 2019 American Association of Endodontists Introduction: This study aimed to compare the incidence of root fractures that led to extraction in immature teeth endodontically treated by mineral trioxide aggregate (MTA) apexification and were restored... to show the survival rate and predisposing factors at a significance level of.05.
