Forty-one crowded and 37 uncrowded dental casts of children in the early mixed dentition were examined by means of digitization using a reflex microscope. Two aspects of alignment were considered: rotation and labio-lingual displacement. Rotations of the incisors were defined as deviations from \u2018ideal\u2019 predicted angles. Displacement of the incisors was measured as the distance between the most labial and most lingually placed incisors. The study showed an increase in rotations amongst the crowded sample. The result of the investigation of the relationship between crowding and displacement was inconclusive. There would appear to be significant differences between the positions of newly erupted crowded and uncrowded incisors. Crowding, however, was not the only factor causing irregularity. <\/jats:p>","DOI":"10.1179\/bjo.20.4.333","type":"journal-article","created":{"date-parts":[[2014,12,16]],"date-time":"2014-12-16T13:22:56Z","timestamp":1418736176000},"page":"333-337","source":"Crossref","is-referenced-by-count":0,"title":["The Relationship of Crowding to the Eruptive Position of the Lower Permanent Incisors"],"prefix":"10.1177","volume":"20","author":[{"given":"C.","family":"Deery","sequence":"first","affiliation":[{"name":"Dental Health Services Research Unit, University of Dundee, Park Place, Dundee DD1 4HR"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1993,11,1]]},"reference":[{"key":"bibr1-bjo.20.4.333","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9416(53)90169-9"},{"volume-title":"The Science and Practice of Dental Surgery","year":"1931","author":"Bennett N.","key":"bibr2-bjo.20.4.333"},{"key":"bibr3-bjo.20.4.333","first-page":"61","volume":"71","author":"Clinch L.
