Unimpeded eruption of mandibular incisors of five experimental and two control rats was induced by cutting off the erupted part of the incisors three times per week for 5\u00a0weeks. The length of the zone of enamel secretion in unimpeded and impeded control incisors was measured on longitudinal and serial transverse histological sections of fixed, demineralised and embedded hemimandibles. Impeded contralateral incisors were also included in the study. The length of the zone of enamel secretion in unimpeded incisors showed an increase to 8,398\u00a0\u00b1\u00a0558\u00a0\u00b5m, that is 161% of the length in control incisors (5,213\u00a0\u00b1\u00a095\u00a0\u00b5m). The contralateral incisor showed a reduction in eruption rate, in length of the secretion zone, and the whole tooth was shifted somewhat apically. The measured length of the secretion zone is in agreement with the observed thickness of enamel (98\u00a0\u00b5m) in unimpeded incisors. The reduced eruption rate and the apical shift of the contralateral incisor are probably due to an increased occlusal load.<\/jats:p>","DOI":"10.1111\/ahe.12547","type":"journal-article","created":{"date-parts":[[2020,3,5]],"date-time":"2020-03-05T03:20:30Z","timestamp":1583378430000},"page":"451-456","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Adaptive amelogenesis during unimpeded eruption of rat mandibular incisor"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9765-3862","authenticated-orcid":false,"given":"Steinar","family":"Risnes","sequence":"first","affiliation":[{"name":"Institute of Oral Biology Faculty of Dentistry University of Oslo Oslo Norway"},{"name":"Laboratoire de Biologie et Biomin\u00e9ralisation des Matrices Extracellulaires Facult\u00e9 de Chirurgie Dentaire Universit\u00e9 Ren\u00e9 Descartes (Paris V) Montrouge France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Goldberg","sequence":"additional","affiliation":[{"name":"Laboratoire de Biologie et Biomin\u00e9ralisation des Matrices Extracellulaires Facult\u00e9 de Chirurgie Dentaire Universit\u00e9 Ren\u00e9 Descartes (Paris V) Montrouge France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,3,4]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"1","volume-title":"Annual Conference of the British Educational Research Association","author":"Coe R.","year":"2002"},{"key":"e_1_2_7_3_1","first-page":"1","article-title":"Using the student's t\u2010test with extremely small sample sizes","volume":"18","author":"De Winter J.
