Background: The restoration of severely decayed primary maxillary anterior teeth is a big challange for pediatric dentists. For the management of such teeth, pedodontists must use intracanal posts, such as composite, polyethylene fiber, and glass fiber posts.
Aim: The aim of this clinical study was to evaluate and compare the marginal adaptation, retention loss, marginal discoloration, and color match and translucency of 3 different intracanal posts (composite, polyethylene fiber, and glass fiber post) in restorations of severely decayed primary maxillary anterior teeth.
Design: A total of 180 severely decayed primary maxillary anterior teeth from children aged 3 to 4 years were selected according to the inclusion criteria. The patients were treated under local and general anesthesia. The teeth were treated endodontically and were randomly divided into 3 groups (n=60): Group I: composite post, Group II: Ribbond polyethylene fiber post, and Group III: glass fiber post. The marginal adaptation, retention loss, marginal discoloration, and color match and translucency were clinically and radioographically evaluated during every follow-up at 6, 12, and18 months and at 24-month intervals.
Results: There was no significant difference between the polyethylene fiber posts and the glass fiber posts and between the polyethylene fiber posts and the composite posts after 24 months (p>0.05). However, there was a significant difference between the composite and the glass fiber posts after 24 months (p<0.05). There was no significant difference in the marginal discoloration and color match and translucency values of the specimens in the composite post, polyethylene fiber post, and glass fiber post groups after 6, 12, 18, and 24 months (p>0.05).
Conclusion: The glass fiber posts showed the maximum retention and marginal adaptation followed by the polyethylene fiber posts. The composite posts showed the least retention and marginal adaptation.
