title: Comparison of compressive strength among three different intracanal post materials in primary anterior teeth: Anin vitrostudy.
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.
  
  
  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. ThePvalue was found to be 0.220.
  
  
  CONCLUSIONS
  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.
