Conventional avulsion versus less traumatic extraction of ankylosed roots with a magnetoelectric device in anterior maxillary areas.

The analysis aimed to compare two different single-tooth extraction surgical approaches in anterior maxillary areas of the ankylosed teeth: less traumatic magneto-electrical (mag) versus conventional tooth extraction (con) in minimizing the adverse effects on post-extractive sockets. Parameters of clinical interest such as intra-surgical fracture of the buccal bone plate, presence of postoperative inflammation, and application of stitches were acquired from medical records. The data were subjected to Pearson's χ2 analysis or to Fisher's exact test with significance at 0.05. Sixty-six hopeless maxillary permanent ankylotic teeth were extracted in the same number of patients. In the mag group 2 incisors suffered a fracture. Two patients out of 40 had signs and symptoms of inflammation that resolved completely within 3 days. In the con group 18 out of 26 patients suffered from buccal alveolar fracture. Six of these patients experienced signs of inflamed tissue. The two groups showed significant differences with p-values ≤0.0009 with regards to fracture (2/38 vs. 18/8) and tissue inflammation variables (2/38 vs. 10/16). A significantly different distribution about the presence of sutures was registered between the mag (4/36) and the con (18/8) group with a p-value <0.0001. Mag group seemed to have reduced frequency of fractured and infected post-extractive sites.
