Twelve of these teeth were decoronated. Variables such as the time of injury, stage of root development and the extent of infraposition were analysed. The vertical changes in the alveolar bone level of the decoronated teeth were assessed on radiographs using a three\u2010point scoring system. Parents of 30 patients with teeth that were not decoronated completed a questionnaire addressing their considerations and concerns regarding the treatment of infraposition.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Teeth with root development in stages 2 and 3 showed a significantly higher rate of severe infraposition during the follow\u2010up visits.

The alveolar bone levels of boys and girls showed improvements of 2.2 and 3.2\u00a0mm, respectively. The optimal age for decoronation to have a considerable increase in bone level was 12.12\u00a0\u00b1\u00a00.83\u00a0years for boys and 11.25\u00a0\u00b1\u00a01.77\u00a0years for girls.
