<div style="text-align: justify;"><strong>Background and Aim: </strong>There have been attempts to restore destroyed primary anterior teeth using a variety of post and core systems, which were able to solve just part of the problems related to this issue. Therefore, the present study aimed to inves-tigate the fracture resistance of restorations supported with a variety of posts and cores in primary anterior teeth.<br>
<strong>Materials and Methods: </strong>The present study was an in vitro experimental study on 40 extracted maxillary primary canine teeth. The teeth were divided into four groups: (I) Grandio Flow composite core and fiberglass post, (II) Grandio Flow composite core and Grandio Flow composite post, (III) Grandio composite core and fiberglass post and (IV) Grandio composite core and Grandio composite post. Then, the fracture re-sistance was compared among the four groups. One-way ANOVA was used to analyze the data.<br>
<strong>Results: </strong>The mean fracture resistance was 398.2±135.2 in group 1, 474.7±100.8 in group 2, 374.3±161.1 in group 3 and 364.4±74.5 in group 4; these differences were not statistically significant (P=0.182).<br>
<strong>Conclusion: </strong>The results of this study showed that the highest fracture resistance was observed in the Grandio Flow composite core and Grandio Flow composite post. Grandio composite core and Grandio composite post showed the lowest fracture resistance; but there were no statistically significant differences among the groups.</div>
