They were divided into two equal groups, prepared for cementing the FRC posts. The Exacto posts (Angelus, Londrina, PR, Brazil) in group 1 and the Reforpost posts (Angelus; Londrina; PR, Brazil) were cemented with dual cure resin cement Breeze Self-Adhesive Resin Cement (Pentron Clinical, Orange, US). Fracture resistance testing was performed on the crown-apical axial direction, using the Hounsfield \/ Tinius Olsen H1-KS, PA, USA mechanical testing apparatus. The behavior of each tooth-post assembly was recorded as a graph. The statistical analysis was done using one way ANOVA (\u03b1=0.05). The differences between the Exacto post group and the Reforpost post group are not statistically significant (p = 0.466). The maximum force recorded was 970 N and the minimum 186N. The mean force at which the fracture occurred was approximately 500N for both groups. The strain test showed that modifying the Reforpost post design did not improve the fracture resistance parameters of the tooth-post assembly through increasing the surface friction or maintaining adhesion to the walls of the root dentin.<\/jats:p>","DOI":"10.25122\/jml-2020-0180","type":"journal-article","created":{"date-parts":[[2021,4,16]],"date-time":"2021-04-16T03:34:21Z","timestamp":1618544061000},"page":"81-85","source":"Crossref","is-referenced-by-count":8,"title":["Fracture resistance of endodontically treated teeth restored with resin post reinforced with glass fiber"],"prefix":"10.25122","volume":"14","author":[{"given":"Mihaela","family":"Chirila","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Endodontics, Faculty of Dental Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, Bucharest, Romania","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Endodontics, Faculty of Dental Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, Bucharest, Romania","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Endodontics, Faculty of Dental Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, Bucharest, Romania","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Endodontics, Faculty of Dental Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, Bucharest, Romania","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"* Corresponding Author: Mihaela Chirila, DMD, PhD, Department of Endodontics, Faculty of Dentistry, \u201eCarol Davila\u201d University of Medicine and Pharmacy, Bucharest.
