Assessment of fracture resistance capacity in endodontically treated teeth with fiberglass post comparing different therapeutic techniques
Journal Title: Revista Uningá - Year 2023, Vol 60, Issue 1
Abstract
Endodontically treated teeth show lower resistance when compared to teeth with pulp vitality, a fact associated to the reduction of mineralized structure. The aim of this study was to evaluate the fracture strength of endodontically treated teeth with 2.5 mm of coronal remnant, which received different intraradicular fiberglass retainers. For sample acquisition, 30 endodontically treated canines were selected, which had their coronal portions removed at 3 mm above the cemento-enamel junction, performing a 2.5 mm splint effect. Three groups were formulated in this study: Fiberglass post without reline (hereafter, FGP); fiberglass post relined with composite resin (anatomical post - hereafter, RFGP), and fiberglass post Splendor-Sap (hereafter, SS). All pins were cemented with dual resin cement, and restored with a core filling and a composite resin dental crown. The samples were subjected to mechanical cycling and fracture strength testing by universal testing machine. The one-way anova test and Tukey’s test were used for statistical evaluation (p-value < 0.05). There were significant differences in fracture strength between the comparative groups (p-value < 0.05), in which the relined (anatomic) fiberglass pin showed higher mean levels of fracture strength (p-value < 0.05), followed by the non-reinforced fiberglass pin and Splendor-Sap fiberglass pin groups.
