Based on the films, 264 lower third molars were classified into an eruption and an impaction group. Root development was recorded according to a quantitative method described by Haavikko (1970), and the eruption status was analyzed using logistic regression.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n In total, 155 (59%) of the M3 inf erupted, and 109 (41%) were impacted at age 20. In 44 (33%) patients both M3 inf were impacted, in 21 (16%) patients one tooth was erupted and the contralateral tooth impacted, and in 67 (51%) patients both M3 inf were erupted. The more mature a tooth was at age 15, the higher was the probability of eruption (odds ratio: 3.89,\n P<\/jats:italic>\n < .001). The growth rate of the root development stage was statistically significantly associated with the probability of eruption (odds ratio: 10.50,\n P<\/jats:italic>\n \u200a=\u200a .041).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Delayed mandibular third molar root development is associated with impaction. Radiographs taken at age 15 may predict the risk of impaction and thereby guide decision making for the orthodontist or the oral and maxillofacial surgeon.<\/jats:p>\n <\/jats:sec>","DOI":"10.2319\/102911-667.1","type":"journal-article","created":{"date-parts":[[2012,6,16]],"date-time":"2012-06-16T00:14:09Z","timestamp":1339805649000},"page":"3-9","source":"Crossref","is-referenced-by-count":26,"title":["Association between third mandibular molar impaction and degree of root development in adolescents"],"prefix":"10.2319","volume":"83","author":[{"given":"S\u00f8ren R\u00f8dsgaard","family":"Lauesen","sequence":"first","affiliation":[{"name":"Private practitioner, Department of Oral and Maxillofacial Surgery, Faculty of Health and Sciences, Institute of Odontology, University of Copenhagen, Denmark."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens O.","family":"Andreasen","sequence":"additional","affiliation":[{"name":"Associate and Consultant oral maxiofacial surgeon, Senior research, Resource Center for Rare Oral Diseases, University Hospital of Copenhagen, Denmark."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas Alexander","family":"Gerds","sequence":"additional","affiliation":[{"name":"Associate Professor, Core Biostatistics, Institute of Public Health, Copenhagen, Denmark."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f8ren Steno Ahrensburg","family":"Christensen","sequence":"additional","affiliation":[{"name":"Research Assistant, Resource Center for Rare Oral Diseases, University Hospital of Copenhagen, Denmark."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mette","family":"Borum","sequence":"additional","affiliation":[{"name":"Head, Municipal Dental Service, Hoeje-Taastrup, Denmark."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f8ren","family":"Hillerup","sequence":"additional","affiliation":[{"name":"Professor, Rigshospitalet and Institute of Odontology, Faculty of Health Sciences, University of Copenhagen, Denmark."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"key":"i0003-3219-83-1-3-b01","series-title":"Am J Orthod","first-page":"237","article-title":"Mandibular growth and third molar impaction","volume":"43","author":"Bj\u00f6rk\n A ,","year":"1957","unstructured":"Bj\u00f6rk\n A , \n \n Jensen\n E , \n \n Palling\n M . \n \n Mandibular growth and third molar impaction .
