Effect of Single Visit Apexification versus Complete Obturation using Mineral Trioxide Aggregate or Biodentine on the Fracture Resistance of Simulated Immature Teeth
Abstract
Introduction: The study was done to evaluate and compare the effect of single visit apexification or full obturation of mineral trioxide aggregate (MTA)/ Biodentine on fracture resistance and pattern of fracture of simulated immature teeth. Methodology: Forty-five extracted maxillary central incisors were decoronated to a standard length of 20 mm and were divided into four experimental groups (n=10) and one control group (n=5). Peeso reamers (#1 to #5) were used to simulate immature teeth until they passed 1mm beyond the apex. Peeso reamer #6 was used 3mm beyond the cemento-enamel junction (CEJ) to mimic Cvek's stage 3 of root development. Canals in group 1 and 3 were completely obturated using MTA and Biodentine, respectively. Apexification with 5mm MTA and biodentine was done in group 2 and 4 and backfilled with guttapercha and AH Plus sealer, respectively. Fracture testing was performed using Universal Testing Machine and data was subjected to statistical analysis. Results: Complete obturation with MTA and Biodentine showed significantly higher fracture resistance than MTA and biodentine apexification groups. Conclusion: Full obturation with bioactive materials reinforces simulated immature teeth.
