The purpose of this study is to examine tooth movement, osteoclasts, and root resorption in rats following several one-hour activations. Rats (n = 144) were randomly assigned to intermittent (multiple activations of 1 hr\/day), continuous, and sham appliances. Twelve rats were killed at 3, 5, 7, and 14 days. Tooth movement, osteoclasts, osteoclast %, and root resorption % were quantified. Continuous force moved molars mesially at days 3 and 14 (p &lt; 0.05), but intermittent and sham did not. Intermittent and continuous force increased osteoclast numbers at days 3, 5, and 7 (p &lt; 0.05). Continuous force increased osteoclast surface on days 3 and 14 (p &lt; 0.05). Continuous force increased root resorption at days 5, 7, and 14 (p &lt; 0.05). These results demonstrate that orthodontic force for one hour in 24 stimulates osteoclasts at compression sites but does not stimulate tooth movement or root resorption.<\/jats:p>","DOI":"10.1177\/00220345010800021101","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T19:39:42Z","timestamp":1231443582000},"page":"457-460","source":"Crossref","is-referenced-by-count":34,"title":["Intermittent Force in Orthodontic Tooth Movement"],"prefix":"10.1177","volume":"80","author":[{"given":"T.","family":"Konoo","sequence":"first","affiliation":[{"name":"Departments of Orthodontics, Kyushu Dental College, 2-6-1 Manazuru Kokurakitaku, Kitakyushu, 803-8580 Japan,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.J.","family":"Kim","sequence":"additional","affiliation":[{"name":"Yonsei University College of Dentistry Dental Hospital, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.M.","family":"Gu","sequence":"additional","affiliation":[{"name":"University of Washington, Seattle, WA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.J.","family":"King","sequence":"additional","affiliation":[{"name":"University of Washington, Seattle, WA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2001,2,1]]},"reference":[{"key":"atypb1","first-page":"363","volume":"122","author":"Baron R.","year":"1986","journal-title":"Am J Pathol"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0765.1982.tb01185.x"},{"key":"atypb3","first-page":"263","volume":"59","author":"Boecler PR","year":"1989","journal-title":"Angle Orthod"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/0889-5406(93)70106-X"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(05)81763-9"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(83)90126-4"},{"key":"atypb7","first-page":"211","volume":"62","author":"Gibson JM","year":"1992","journal-title":"Angle Orthod"},{"key":"atypb8","volume-title":"Dentofacial orthopedics with functional appliances","author":"Graber TM","year":"1985"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(05)81579-3"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1016\/8756-3282(91)90029-I"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(98)70202-1"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(78)90033-7"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(82)90092-6"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.5650020617"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(75)90084-6"},{"key":"atypb16","first-page":"1","volume":"10","author":"Reitan K.","year":"1951","journal-title":"Acta Odontol Scand (Suppl"},{"key":"atypb17","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198466030-00012"},{"key":"atypb18","doi-asserted-by":"publisher","DOI":"10.1002\/jor.1100060411"},{"key":"atypb19","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(83)90173-5"},{"key":"atypb20","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0757.1995.tb00059.x"},{"key":"atypb21","doi-asserted-by":"publisher","DOI":"10.1007\/s002239900393"}],"container-title":["Journal of Dental Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00220345010800021101","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00220345010800021101","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T21:02:34Z","timestamp":1777496554000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/00220345010800021101"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,2]]},"references-count":21,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2001,2]]}},"alternative-id":["10.1177\/00220345010800021101"],"URL":"https:\/\/doi.org\/10.1177\/00220345010800021101","relation":{},"ISSN":["0022-0345","1544-0591"],"issn-type":[{"value":"0022-0345","type":"print"},{"value":"1544-0591","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,2]]}}}
