Abstract

Aim: Clinical and radiographic assessment of the regenerative potential of bilateral immature permanent maxillary central incisors with necrotic pulps using blood clot (BC) and platelet-rich plasma (PRP) scaffolds. Trial design: This is a split mouth double-blinded parallel randomized controlled clinical trial. Subjects and methods: Randomization and blinding: the study started with 15 patients with bilateral maxillary immature permanent central incisors with necrotic pulp. The two upper bilateral central incisors were randomly assigned to either the control (BC scaffold) group I or examined (PRP scaffold) group II. Participant: 13 patients aged 8–14 years fulfilled the study requirements. A follow-up was done for 3, 6, 9, and 12 months. Standardized radiographs were collected during the follow-up period, and radiographic changes were measured using Image J software. Primary outcome measured were clinical: pain, mobility, swelling, and sinus/fistula. Radiographic outcome included increased root length and increase in root thickness. Secondary outcomes were clinical: discoloration and sensibility test. Radiographic outcome included an increase in bone density measurements and a decrease in apical diameter. Standardized radiographs were collected during the follow-up period, and radiographic changes were measured using Image J software. Results: All 26 treated teeth survived during the 12-month follow-up period with 100% success rate. PRP-treated teeth showed a statistically significant increase in radiographic root length, width, periapical bone density, and a decrease in apical diameter when compared with BC. At the end of 12 months, all treated teeth did not respond to the sensibility test. BC displayed a significantly higher amount of crown discoloration compared to the PRP group. Conclusion: For necrotic immature teeth, regenerative endodontic treatment using PRP is a desirable alternative to BC and shows excellent 12-months prognosis.
