However, little is known concerning how jaw movements develop without tooth eruption. To answer this question, we studied masticatory behavior in the osteopetrotic mouse, where tooth eruption does not occur and periodontal mechanoreceptors are missing. A masticatory sequence of the osteopetrotic mouse was divided into two stages: incision and chewing. Incision is characterized by small amplitude and rapid (7 Hz) open-close jaw movements, while slow (5 Hz) and large amplitude open-close jaw movements characterize chewing. The frequency and properties of jaw movements were comparable with those in the normal mouse, though the osteopetrotic mouse had a higher cycle number during incision than did the normal mouse. These results indicate that conversion from sucking to mastication occurs in the anodontic mouse, and the central pattern generator producing the masticatory rhythm develops almost normally without tooth eruption.<\/jats:p>","DOI":"10.1177\/154405910208100903","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T19:39:42Z","timestamp":1231443582000},"page":"594-597","source":"Crossref","is-referenced-by-count":16,"title":["Characteristics of Mastication in the Anodontic Mouse"],"prefix":"10.1177","volume":"81","author":[{"given":"M.","family":"Kobayashi","sequence":"first","affiliation":[{"name":"Department of Oral Physiology, Osaka University Graduate School of Dentistry, 1-8, Yamadaoka, Suita, Osaka 565-0871, Japan;"},{"name":"Clinical Laboratory, Osaka University Dental Hospital, Yamadaoka, Suita, Osaka 565-0871, Japan; and"},{"name":"Department of Oral Anatomy, Faculty of Dentistry, Hiroshima University, Hiroshima 734-8553, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Masuda","sequence":"additional","affiliation":[{"name":"Department of Oral Physiology, Osaka University Graduate School of Dentistry, 1-8, Yamadaoka, Suita, Osaka 565-0871, Japan;"},{"name":"Clinical Laboratory, Osaka University Dental Hospital, Yamadaoka, Suita, Osaka 565-0871, Japan; and"},{"name":"Department of Oral Anatomy, Faculty of Dentistry, Hiroshima University, Hiroshima 734-8553, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Kishino","sequence":"additional","affiliation":[{"name":"Department of Oral Physiology, Osaka University Graduate School of Dentistry, 1-8, Yamadaoka, Suita, Osaka 565-0871, Japan;"},{"name":"Clinical Laboratory, Osaka University Dental Hospital, Yamadaoka, Suita, Osaka 565-0871, Japan; and"},{"name":"Department of Oral Anatomy, Faculty of Dentistry, Hiroshima University, Hiroshima 734-8553, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Ishida","sequence":"additional","affiliation":[{"name":"Department of Oral Physiology, Osaka University Graduate School of Dentistry, 1-8, Yamadaoka, Suita, Osaka 565-0871, Japan;"},{"name":"Clinical Laboratory, Osaka University Dental Hospital, Yamadaoka, Suita, Osaka 565-0871, Japan; and"},{"name":"Department of Oral Anatomy, Faculty of Dentistry, Hiroshima University, Hiroshima 734-8553, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Maeda","sequence":"additional","affiliation":[{"name":"Department of Oral Physiology, Osaka University Graduate School of Dentistry, 1-8, Yamadaoka, Suita, Osaka 565-0871, Japan;"},{"name":"Clinical Laboratory, Osaka University Dental Hospital, Yamadaoka, Suita, Osaka 565-0871, Japan; and"},{"name":"Department of Oral Anatomy, Faculty of Dentistry, Hiroshima University, Hiroshima 734-8553, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Morimoto","sequence":"additional","affiliation":[{"name":"Department of Oral Physiology, Osaka University Graduate School of Dentistry, 1-8, Yamadaoka, Suita, Osaka 565-0871, Japan;"},{"name":"Clinical Laboratory, Osaka University Dental Hospital, Yamadaoka, Suita, Osaka 565-0871, Japan; and"},{"name":"Department of Oral Anatomy, Faculty of Dentistry, Hiroshima University, Hiroshima 734-8553, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2002,9,1]]},"reference":[{"key":"APPENTENG-ETAL-1982","doi-asserted-by":"publisher","DOI":"10.1152\/jn.1982.48.1.27"},{"key":"BOSMA-1967","unstructured":"Bosma JF -1967- Human infant oral function.
