Evaluation of the Effects of Different Types of Resin Cement Systems on the Push-Out Bond Strength of the Fiber Post to Intracanal Dentin in Anterior Primary Teeth

Figure 1

Schematic representation of the specimen preparation procedures: (a) removal of the anatomical crowns 2 mm above the cementoenamel junction; (b) pulpectomy treatment; (c) post space preparation (GIC, glass ionomer cement); (d) fiber post cementation; (e) embedding the specimen in acrylic resin; (f) root sectioning in the middle of the prepared area to obtain a 1-mm thick slice; (g) push-out bond strength test.
