Comparison of Compressive strength between three types of crown-root restorative techniques in primary anterior teeth

Abstract

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. Sixty extracted primary anterior teeth were selected for the study. The samples were divided into three groups of twenty teeth each. Pulp therapy was followed by intracanal post and crown buildup. The samples were mounted in self-cure acrylic and subjected to a compressive strength test using a universal testing machine (testometric). The maximum force at which the tooth fractured was recorded.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.Within the limitations of this research, we recommend using posts made of polyethylene to restore damaged teeth.
