Table 2 Root resorption and roots out of the bone after orthodontic treatment in low-, average-, and high-angle patients
From: Evaluation of mandibular anterior alveolus in different skeletal patterns
Average initial root length, mm (S.D.) | Number of patients with root resorption over 10 % | Percentage of patients with root resorption over 10 % | Percentage of patients with the tooth out of the bone | |
|---|---|---|---|---|
Low-angle | 20.75 (1.7) | 1 | 1/11 = 9 % | 0/11 = 0 % |
Average-angle | 20 (1.6) | 4 | 4/20 = 20 % | 1/20 = 5 % |
High-angle | 20.5 (0.8) | 6 | 6/27 = 22 % | 6/27 = 22 % |
