ABSTRACT
Objective: The objective of our study was to compare the fracture resistance and the mode of
failure among three different post materials in primary anterior teeth. Materials and Methods: A total of sixty extracted primary anterior teeth were selected for the study. The
samples were divided into three groups of twenty teeth each: Group I (Ribbond), Group
II (Omega loop), and Group III (Glass fiber post). Pulp therapy was followed by intracanal
post and crown buildup. The samples were mounted in self-cure acrylic and subjected
to compressive strength test using universal testing machine (Instron). The maximum
force at which the tooth fractured was recorded. Results: The values were subjected to one-way analysis of variance. The mean compressive strength
values of Ribbond, omega loop, and glass fiber post were found to be 83.25 N, 61.60
N, and 75.55 N, respectively. The P value was found to be 0.220. Conclusion: Group I (Ribbond) showed the highest fracture resistance values followed by Group
III (Glass fiber post) and Group II (Omega loop). Although there is difference in
mean values, they were nonsignificant.
