Mean age of the patients was 10.7\u00a0years (6.8\u201317.8) at the time of trauma and 14.9\u00a0years (9.3\u201322.0) at decoronation. The mean follow\u2010up period was 4.6\u00a0years (1.0\u201319.3\u00a0years). The study evaluated development of the marginal alveolar bone level with a three\u2010point scoring system: 1\u00a0=\u00a0Unchanged or reduced alveolar bone level, 2\u00a0=\u00a0A moderate increase in alveolar bone level, and 3\u00a0=\u00a0A considerable increase in alveolar bone level. The final group for statistical evaluation comprised 75 patients: 56 boys and 19 girls who had only one tooth decoronated.
