Efficacy of intracanal biological and fiber posts in the rehabilitation of grossly mutilated primary incisors: a clinical study

Abstract

Background: The aim of this study was to assess the efficacy of conventional fiber posts with biological posts followed by strip crowns in the restoration of grossly mutilated primary anterior teeth.Methods: A total number of 10 patients with 20 grossly mutilated primary anterior teeth were selected. After pulpectomy, samples were randomly divided into 2 groups, group I and II, post space was prepared in both the groups, followed by placing conventional fiber posts and biological posts in group I and group II respectively. Finally, samples in both the groups were then restored with strip crowns. Patients were recalled for follow up examination at 3, 6 and 9 months intervals by an independent operator who was blinded about the procedure to assess longevity, gingival health, color change of crowns and parents’ acceptability of restorations.Results: After 9 months follow up period 100% of the biological posts survived while only 60% of the conventional fibre posts were able to survive (p>0.05). Only 20% of the cases in group I showed mild gingival inflammation around the post while no gingival inflammation was seen in group II. Non - significant results were found on comparing color change of crowns and parents acceptance at 6 months follow up.Conclusions: Both conventional fiber post and biological proved to be clinically successful in terms of their survival, gingival health, parents’ acceptability and color stability of crowns. Biological restorations proved to be a viable alternative for the restoration of grossly mutilated primary anterior in terms of longevity, gingival health, parents’ acceptability and color change of crown.
