It is proposed in the literature that teeth sustaining mild trauma with minor damage to the periodontium (e.g. subluxation) should be followed for a period of time before being subjected to orthodontic forces. A minimum period of 3\u2003months has been proposed. In this study, we used an animal model to investigate whether shorter observation periods could be established in case of mild trauma. The periradicular region of rat molars was examined microscopically to determine the biological events of tooth movement started 15 and 30\u2003days after intentional subluxation using an experimental method to induce dentoalveolar trauma. Thirty adult male Wistar rats were assigned to 6 groups (<jats:italic>n<\/jats:italic>\u2003=\u20035): Group 1 (control \u2013 no trauma\/orthodontic movement); Group 2: the animals received an orthodontic device and were sacrificed after 7\u2003days; Groups 3 and 4: dentoalveolar trauma (subluxation) was experimentally induced by the application of an axial force of 900\u2003cN on the occlusal surface of the maxillary right first molar, and the animals were sacrificed after 22 and 37\u2003days, respectively; and Groups 5 and 6: 15 and 30\u2003days, respectively, after force application, an orthodontic device was installed and the rats were sacrificed 7\u2003days later. In G5 and G6, the periodontal ligament and pulp tissue were rich in cellular elements and blood vessels, the alveolar bone was preserved, and the root surface presented only very small areas of surface resorption (cementum), maintaining the characteristics of normality. In conclusion, the microscopic alterations in the gingival and periodontal tissues in response to an experimentally induced mild dentoalveolar trauma simulating subluxation were not sufficient to contraindicate starting the orthodontic movement 15 and 30\u2003days after trauma.<\/jats:p>","DOI":"10.1111\/j.1600-9657.2011.01047.x","type":"journal-article","created":{"date-parts":[[2011,7,27]],"date-time":"2011-07-27T00:32:20Z","timestamp":1311726740000},"page":"114-120","source":"Crossref","is-referenced-by-count":9,"title":["Microscopic evaluation of induced tooth movement in traumatized teeth: an experimental study in rats"],"prefix":"10.1111","volume":"28","author":[{"given":"Alex Luiz Pozzobon","family":"Pereira","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos Rog\u00e9rio","family":"de Mendon\u00e7a","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celso Koogi","family":"Sonoda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mauro Carlos Agner","family":"Bussato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osmar Aparecido","family":"Cuoghi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aubrey Fernando","family":"Fabre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,7,26]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-9657.2003.00138.x"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-9657.2001.170602.x"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-4469.2004.00230.x"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1590\/S1806-83242010000100013"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/5.3.173"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(82)90317-7"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(79)90135-0"},{"key":"e_1_2_7_9_2","first-page":"304","article-title":"Timing of orthodontic tooth movement in a case with traumatized and avulsed anterior teeth","volume":"55","author":"Gazit E","year":"1988","journal-title":"ASCD J Dent Child"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2003.06.019"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/13.5.372"},{"key":"e_1_2_7_12_2","first-page":"234","article-title":"Traumatically intruded teeth","volume":"57","author":"Turley PK","year":"1987","journal-title":"Angle Orthod"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(84)90122-2"},{"key":"e_1_2_7_14_2","first-page":"213","article-title":"The treatment of traumatized permanent anterior teeth: case report & literature review.
