Suitable selection of restorative materials is a requisite for long-term clinical success.<\/jats:p>\n <\/jats:sec>\n \n Aims:<\/jats:title>\n To compare the fracture resistance of endodontically treated teeth restored with three different posts luted using two different cements under all ceramic crowns.<\/jats:p>\n <\/jats:sec>\n \n Settings and Design:<\/jats:title>\n \n This\n in vitro<\/jats:italic>\n study was conducted in the Department of Prosthodontics, Government Dental College, Kottayam, Kerala, India.\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Material:<\/jats:title>\n Thirty endodontically treated single-rooted mandibular premolars in which post spaces were prepared and divided into three different groups. Group 1 (n = 10): zirconia post group. Group 2 (n = 10): quartz fibre post group. Group 3 (n = 10): glass fibre post group. Each group is sub-divided into two based on the luting system: resin-modified glass ionomer cement (RMGIC) or dual-cure resin cement (DCRC). The fracture resistance testing was performed in a universal testing machine with a crosshead speed of 0.5 mm\/min.<\/jats:p>\n <\/jats:sec>\n \n Statistical Analysis Used:<\/jats:title>\n The mean fracture resistance were analysed using independent sample Student t-test and one-way ANOVA.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Within the zirconia post group, the mean fracture resistance was higher in DCRC sub-group compared to the RMGIC sub-group and the difference was statistically significant (p = 0.017). The difference in fracture resistance between three different post systems was not found to be statistically significant with respect to both the luting systems.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n It was observed that when zirconia post is used, the mean fracture resistance was higher in dual-cure resin group compared to the resin-modified GIC group.<\/jats:p>\n
