Biologic reinforcement of compromised permanent incisors in children

Abstract

Purpose: The aim of this study was to evaluate the clinical and radiographic success of biologic primary incisors as intraradicular post–core reinforcement in management of compromised permanent incisors in children. Patients and methods: Twenty-four children patients aged 10–15 years old were selected from Outpatients Clinic of Pedodontic Department, Faculty of Dentistry, Tanta University. The patients had upper permanent central incisors with flared canal indicated for intraradicular reinforcement. The patients were randomly divided into two groups, 12 patients each; biologic group were reinforced by human extracted primary incisors, and fiber post group that their compromised teeth were reinforced by fiber posts (EasyPost) with RelyX Unicem. Clinical assessment of jacket crowns, gingival health, reinforced permanent teeth, and intraradicular reinforcing system was recorded. The healthy periapical area (no pathosis), pathosis did not require immediate treatment and pathosis required immediate treatment were recorded as radiographic assessment. The children were followed up clinically and radiographically at 3, 6, 12, and 18 months after treatment. Results: The overall clinical success rate of biologic group was 75 and 100% for fiber post group. There were no statistically significant differences in clinical assessment between the two groups (P > 0.05). The overall radiographic success rate of biologic group was 77.8 and 83% for fiber post group at the end of study. There were no statistically significant differences in radiographic assessment between the two groups (P > 0.05). Conclusion: The use of extracted primary incisors as biologic post–core in rehabilitation of compromised flared upper central incisors have continued to function well for 1.5 years with overall clinical and radiographic success rate of 75 and 77.8%, respectively.
