The method was applied to two groups of rats: one group with lower incisors in impeded eruption and another group with the left lower incisor in the unimpeded state. The teeth were divided into six equal segments, from which consecutive ground sections were obtained. The distance of each ground section from the posterior border of the alveolar bone was calculated. Each section was magnified, traced, and the tracings fed into a computer by a sonic digitizer. The perimeters and areas of dentine and pulp in each ground section were calculated by the computer. The mean odontoblast density along the predentine was evaluated from histological sections taken both from the same tooth segments and from teeth sectioned midsagittally. These served for the estimation of the predentine area occupied by the average odontoblast. In the impeded group, this area was 11% larger than in the unimpeded one. Outer dimensions of teeth, namely the circumference of the dentine, the labiolingual width, and the mesiolateral width remained constant and equal for both groups.<\/jats:p><jats:p>Daily rates of dentine apposition were computed and were found to vary according to the age of the odontoblasts. Odontoblasts of impeded teeth started to secrete matrix at a rate of 17 \u03bcm\/day, which increased slightly to 19 \u03bcm\/day and later declined to 7 \u03bcm\/day on the 38th day. Dentine production of unimpeded odontoblasts, on the other hand, started at a rate of 16 \u03bcm\/day and gradually increased to 34 \u03bcm\/day on the 17th day. The daily rate of odontoblast cell\u2010production was 2.29 times greater in the unimpeded teeth (112.9 \u00d7 10<jats:sup>3<\/jats:sup> cells\/day instead of 49.4 \u00d7 10<jats:sup>3<\/jats:sup> cells\/day). The absolute mean daily rate of odontoblast cell loss increased in unimpeded teeth from 33.1 \u00d7 10<jats:sup>3<\/jats:sup> cells\/day to 42.9 \u00d7 10<jats:sup>3<\/jats:sup> cells\/day. On the other hand, the relative daily rate of cell loss decreased from 73.6 cells\/day\/1\u03bcm eruption to 47.7 cells\/day\/1\u03bcm eruption.<\/jats:p>","DOI":"10.1002\/ar.1092110215","type":"journal-article","created":{"date-parts":[[2005,2,26]],"date-time":"2005-02-26T23:28:34Z","timestamp":1109460514000},"page":"218-225","source":"Crossref","is-referenced-by-count":15,"title":["Odontoblast turnover in the impeded and unimpeded rat incisor derived from computerized histomorphometry"],"prefix":"10.1002","volume":"211","author":[{"suffix":"Jr.","given":"M.","family":"Weinreb","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Steigman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Zajicek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Michaeli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,26]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"413","article-title":"Innerenamel epithelium cell production rates","volume":"5","author":"Bar\u2010lev M.","year":"1976","journal-title":"Cell Tissue Kinet."},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(75)90134-X"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1159\/000144838"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016357509004629"},{"key":"e_1_2_1_6_1","first-page":"59","volume-title":"Histopathologic Technic and Practical Histochemistry","author":"Lillie R.","year":"1965"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(81)90103-5"},{"key":"e_1_2_1_8_1","first-page":"73","article-title":"On the derivation of cell kinetics from histomorphology, observed in the rat incisor odontoblast","volume":"14","author":"Michaeli Y.","year":"1981","journal-title":"Cell Tissue Kinet."},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345750540043001"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345680470042101"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00209242"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(81)90012-1"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1090630402"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1001420402"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1092050410"},{"key":"e_1_2_1_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345690480010401"},{"key":"e_1_2_1_17_1","first-page":"207","article-title":"The rodent incisor tooth proliferon","volume":"9","author":"Zajicek G.","year":"1976","journal-title":"Cell Tissue Kinet."},{"key":"e_1_2_1_18_1","first-page":"35","article-title":"Kinetics of the inner enamel epithelium in the adult rat incisor during accelerated eruption","volume":"5","author":"Zajicek G.","year":"1972","journal-title":"Cell Tissue Kinet."}],"container-title":["The Anatomical Record"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Far.1092110215","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ar.1092110215","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T14:08:52Z","timestamp":1697810932000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ar.1092110215"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1985,2]]},"references-count":17,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1985,2]]}},"alternative-id":["10.1002\/ar.1092110215"],"URL":"https:\/\/doi.org\/10.1002\/ar.1092110215","archive":["Portico"],"relation":{},"ISSN":["0003-276X","1097-0185"],"issn-type":[{"value":"0003-276X","type":"print"},{"value":"1097-0185","type":"electronic"}],"subject":[],"published":{"date-parts":[[1985,2]]}}}
