Specimens of periodontal ligament were obtained from the buccal and lingual\/palatal aspects of the first molars from the maxilla and mandible of 12 horses. The animals were assigned to three age groups. Histological sections were prepared from three specific horizontal levels of the periodontal ligament and examined with conventional and polarized-light microscopy. At the gingival level, collagen fascicles (diameter &gt; 200 \u03bcm) were densely packed. Their spatial alignment was the same in all age groups. The architecture of the collagen fiber apparatus differed at the middle and apical levels in the three age groups. There was a clear distinction between fibers, bundles, and fascicles. Bundling of collagen fibers, density of the fiber arrangement, and collagen fascicles with an alveolo-cemental orientation increased with age. The collagen fiber apparatus of the equine periodontal ligament is highly adaptive, responding continuously to the dynamic changes in the periodontal environment. Site-specific arrangements and age-dependent structural variations are assumed to maintain tooth support as the reserve crown gradually decreases in length with progressive dental attrition. Most of the age-dependent changes to the periodontal ligament in teeth examined in this study occurred at the apical level. The apical region of young teeth had no periodontal attachment, while the roots of older teeth were firmly attached to the alveolus. When evaluating periodontal ligament development, the individual tooth's \u2018dental age\u2019 should be considered rather than the animal's age to account for individual tooth eruption times.<\/jats:p>","DOI":"10.1177\/089875640602300303","type":"journal-article","created":{"date-parts":[[2016,4,28]],"date-time":"2016-04-28T05:34:12Z","timestamp":1461821652000},"page":"143-147","source":"Crossref","is-referenced-by-count":27,"title":["Collagen Fiber Architecture of the Periodontal Ligament in Equine Cheek Teeth"],"prefix":"10.1177","volume":"23","author":[{"given":"Carsten","family":"Staszyk","sequence":"first","affiliation":[{"name":"From the Institute of Anatomy, University of Veterinary Medicine, Hannover, Bischofsholer Damm 15, D-30173 Hannover, Germany; and the Institute of Mechanics (Jacob), University of Hannover, Appelstra\u00dfe 11, D-30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wiebke","family":"Wulff","sequence":"additional","affiliation":[{"name":"From the Institute of Anatomy, University of Veterinary Medicine, Hannover, Bischofsholer Damm 15, D-30173 Hannover, Germany; and the Institute of Mechanics (Jacob), University of Hannover, Appelstra\u00dfe 11, D-30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Georg","family":"Jacob","sequence":"additional","affiliation":[{"name":"From the Institute of Anatomy, University of Veterinary Medicine, Hannover, Bischofsholer Damm 15, D-30173 Hannover, Germany; and the Institute of Mechanics (Jacob), University of Hannover, Appelstra\u00dfe 11, D-30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hagen","family":"Gasse","sequence":"additional","affiliation":[{"name":"From the Institute of Anatomy, University of Veterinary Medicine, Hannover, Bischofsholer Damm 15, D-30173 Hannover, Germany; and the Institute of Mechanics (Jacob), University of Hannover, Appelstra\u00dfe 11, D-30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2006,9,1]]},"reference":[{"key":"bibr1-089875640602300303","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.1997.tb01671.x"},{"key":"bibr2-089875640602300303","doi-asserted-by":"publisher","DOI":"10.1177\/089875640302000401"},{"key":"bibr3-089875640602300303","doi-asserted-by":"crossref","first-page":"31","DOI":"10.2460\/ajvr.1996.57.01.31","volume":"57","author":"Kirkland KD","year":"1996","journal-title":"Am J Vet Res"},{"key":"bibr4-089875640602300303","doi-asserted-by":"publisher","DOI":"10.1016\/B0-70-202724-3\/50013-X"},{"key":"bibr5-089875640602300303","first-page":"529","volume":"188","author":"Webb PP","year":"1996","journal-title":"J Anat"},{"key":"bibr6-089875640602300303","first-page":"1135","volume":"12","author":"Benjamin M","year":"1997","journal-title":"Histol Histopathol"},{"key":"bibr7-089875640602300303","volume-title":"Kaukraft und Kaudruck des Pferdes","author":"Ritter G","year":"1953"},{"key":"bibr8-089875640602300303","doi-asserted-by":"publisher","DOI":"10.21836\/PEM20060102"},{"key":"bibr9-089875640602300303","volume-title":"Food processing and digestibility in horses (Equus caballus)","author":"Collinson M","year":"1994"},{"key":"bibr10-089875640602300303","doi-asserted-by":"publisher","DOI":"10.1136\/inpract.19.4.186"},{"key":"bibr11-089875640602300303","first-page":"35","volume-title":"The periodontal ligament in health and disease","author":"Sloan P","year":"1995"},{"key":"bibr12-089875640602300303","first-page":"253","volume-title":"Histology","author":"Freeman E","year":"1998"},{"key":"bibr13-089875640602300303","first-page":"236","volume-title":"Histology","author":"Ten Cate AR","year":"1998"},{"key":"bibr14-089875640602300303","doi-asserted-by":"publisher","DOI":"10.1016\/j.archoralbio.2004.10.001"},{"key":"bibr15-089875640602300303","first-page":"78","volume-title":"Histology","author":"Ten Cate AR","year":"1998"},{"key":"bibr16-089875640602300303","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1972.43.1.17"},{"key":"bibr17-089875640602300303","unstructured":"Wulff W.
