A retrospective analysis was conducted via spreadsheets that showed patients who were treated with post-and-cores between August 2016 and March 2020. A total of 524 records were included in the analysis according to the inclusion criteria. Data were analysed using Kaplan–Meier and Cox proportional hazards analysis. While a statistically significant difference between the post-and-core survival among age, restoration type, cement type, opposing dentition, and service time was determined (p<0.001), a statistically significant difference with tooth position and sex was not detected (p>0.05). The analyzes showed no evidence that different post-and-core systems (prefabricated glass and carbon fiber reinforced composite resin, cast metal and prefabricated metal) were significantly associated with post-and-core survival. However, opposing dentition, type of cement, and restoration exhibited a statistically significant difference with the post-and-core survival.eninfo:eu-repo/semantics/openAccessArticle101738310.33715/inonusaglik.1019047514337
