This was accomplished by use of a video microscope to track the position of an optical ruling on the erupting tooth relative to a reference ruling mounted on adjacent teeth that were in occlusion. Net eruptive movements averaging 25-75 \u03bcm occurred from one day to the next until the tooth was almost in occlusion; then the eruptive rate slowed. Eruption occurred almost entirely at night. During the day, there was a marked slowing or cessation of eruption and often intrusion, which appeared to be related to masticatory activity.<\/jats:p>","DOI":"10.1177\/00220345910700010101","type":"journal-article","created":{"date-parts":[[2010,11,28]],"date-time":"2010-11-28T21:14:56Z","timestamp":1290978896000},"page":"15-18","source":"Crossref","is-referenced-by-count":17,"title":["Video Microscope Observations of Human Premolar Eruption"],"prefix":"10.1177","volume":"70","author":[{"given":"W.R.","family":"Proffit","sequence":"first","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, University of North Carolina, Chapel Hill, North Carolina 27599-7450"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.R.","family":"Prewitt","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, University of North Carolina, Chapel Hill, North Carolina 27599-7450"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.S.","family":"Baik","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, University of North Carolina, Chapel Hill, North Carolina 27599-7450"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.F.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, University of North Carolina, Chapel Hill, North Carolina 27599-7450"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1991,1,1]]},"reference":[{"key":"atypb1","unstructured":"Berkovitz, B.K.
