The Malmgren Index was used to describe the degree of root resorption.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Severe root resorption (>2\u00a0mm, score 3) was found in 25.6% of the patients at the end of treatment. Extreme root resorption was found in one patient. Root resorption was seen more frequently in the maxillary incisor region. There was no correlation between the severity of root resorption after 6\u00a0months and the amount observed at the end of treatment. Furthermore, no correlation was seen between treatment duration and the severity of root resorption.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Clinically significant resorption was diagnosed in 25.6% of the patients, but no correlations, either with the resorption seen after 6\u00a0months or with the length of treatment, were found. Radiographic examination after 3 to 6\u00a0months of orthodontic treatment is too early and will not reduce the number of patients who will have teeth with severe root resorption.<\/jats:p>\n <\/jats:sec>","DOI":"10.2319\/042012-332.1","type":"journal-article","created":{"date-parts":[[2012,10,23]],"date-time":"2012-10-23T11:27:12Z","timestamp":1350991632000},"page":"389-393","source":"Crossref","is-referenced-by-count":20,"title":["Root resorption diagnosed with cone beam computed tomography after 6 months and at the end of orthodontic treatment with fixed appliances"],"prefix":"10.2319","volume":"83","author":[{"given":"Dimitrios","family":"Makedonas","sequence":"first","affiliation":[{"name":"Research Scientist, Department of Orthodontics, Institute of Odontology, Sahlgrenska Academy at University of Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henrik","family":"Lund","sequence":"additional","affiliation":[{"name":"Consultant, Department of Oral and Maxillofacial Radiology, Institute of Odontology, Sahlgrenska Academy at University of Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Hansen","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Orthodontics, University Clinics of Odontology, Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"issue":"4","key":"i0003-3219-83-3-389-b01","series-title":"Am J Orthod Dentofacial Orthop","first-page":"462","article-title":"Root resorption associated with orthodontic tooth movement: a systematic review","volume":"137","author":"Weltman\n B ,","year":"2010","unstructured":"Weltman\n B , \n \n Vig\n KW , \n \n Fields\n HW , \n \n Shanker\n S , \n \n Kaizar\n EE . \n \n Root resorption associated with orthodontic tooth movement: a systematic review .
