Most non-mammalian vertebrates continuously replace their dentition but an anomalous group of squamates has forgone this process in only having one tooth generation; these squamates all have apically implanted teeth, a condition known as acrodonty. Acrodont dentition and various characteristics attributed to it, including a lack of replacement, have often been defined ambiguously. This study explores this type of implantation through histology in the ontogeny of the acrodont agamid\n                    <jats:italic>Pogona vitticeps.<\/jats:italic>\n                    The non-replacing teeth of this squamate provides an opportunity to study wear adaptations, maintenance of occlusion in a non-mammalian system, and most importantly post-eruption changes in the tooth bone interface. In this study the post-eruption changes combined with dental wear likely gives the appearance of acrodont implantation.\n                  <\/jats:p>","DOI":"10.7717\/peerj.5923","type":"journal-article","created":{"date-parts":[[2018,11,8]],"date-time":"2018-11-08T04:37:54Z","timestamp":1541651874000},"page":"e5923","source":"Crossref","is-referenced-by-count":19,"title":["Histological analysis of post-eruption tooth wear adaptations, and ontogenetic changes in tooth implantation in the acrodontan squamate\n                    <i>Pogona vitticeps<\/i>"],"prefix":"10.7717","volume":"6","author":[{"given":"Yara","family":"Haridy","sequence":"first","affiliation":[{"name":"Department of Biology, University of Toronto Mississauga, Mississauga, Ontario, Canada"},{"name":"Museum f\u00fcr Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Invalidenstra\u00dfe, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4443","published-online":{"date-parts":[[2018,11,8]]},"reference":[{"key":"10.7717\/peerj.5923\/ref-1","doi-asserted-by":"publisher","first-page":"193","DOI":"10.1163\/156853807780202512","article-title":"Growth layers in bones and acrodont teeth of the agamid lizard Laudakia stoliczkana (Blanford, 1875) (Agamidae, Sauria)","volume":"28","author":"Ananjeva","year":"2007","journal-title":"Amphibia-Reptilia"},{"issue":"Part 4","key":"10.7717\/peerj.5923\/ref-2","first-page":"737","article-title":"Tooth form, growth, and function in Triassic rhynchosaurs (Reptilia, Diapsida)","volume":"27","author":"Benton","year":"1984","journal-title":"Palaeontology"},{"key":"10.7717\/peerj.5923\/ref-3","volume-title":"The teeth of non-mammalian vertebrates","author":"Berkovitz","year":"2016"},{"key":"10.7717\/peerj.5923\/ref-4","doi-asserted-by":"publisher","first-page":"15787","DOI":"10.1038\/s41598-017-16056-3","article-title":"Histological evidence for a dynamic dental battery in hadrosaurid dinosaurs","volume":"7","author":"Bramble","year":"2017","journal-title":"Scientific Reports"},{"key":"10.7717\/peerj.5923\/ref-5","doi-asserted-by":"publisher","first-page":"322","DOI":"10.1111\/joa.12280","article-title":"Tooth counts through growth in diapsid reptiles: implications for interpreting individual and size-related variation in the fossil record","volume":"226","author":"Brown","year":"2015","journal-title":"Journal of Anatomy"},{"key":"10.7717\/peerj.5923\/ref-6","doi-asserted-by":"publisher","first-page":"118","DOI":"10.1016\/j.archoralbio.2012.10.019","article-title":"Odontogenesis in the Veiled Chameleon (Chamaeleo calyptratus)","volume":"58","author":"Buchtov\u00e1","year":"2013","journal-title":"Archives of Oral Biology"},{"key":"10.7717\/peerj.5923\/ref-7","volume-title":"A survey of tooth attatchment histology in squamata: the evaluation of tooth attatchment classiciation and characters","author":"Budney","year":"2004"},{"key":"10.7717\/peerj.5923\/ref-8","doi-asserted-by":"publisher","first-page":"138","DOI":"10.1671\/0272-4634(2006)26[138:TSHITC]2.0.CO;2","article-title":"Tooth socket histology in the Cretaceous snake Dinilysia, with a review of amniote dental attachment tissues","volume":"26","author":"Budney","year":"2006","journal-title":"Journal of Vertebrate Paleontology"},{"key":"10.7717\/peerj.5923\/ref-9","doi-asserted-by":"publisher","first-page":"687","DOI":"10.1111\/j.1096-3642.2007.00280.x","article-title":"Ontogeny, anatomy and attachment of the dentition in mosasaurs (Mosasauridae: Squamata)","volume":"149","author":"Caldwell","year":"2007","journal-title":"Zoological Journal of the Linnean Society"},{"issue":"1","key":"10.7717\/peerj.5923\/ref-10","doi-asserted-by":"publisher","first-page":"85","DOI":"10.1111\/j.1469-7998.1973.tb04654.x","article-title":"The dentition and dental tissues of the agamid lizard, Uromastyx","volume":"169","author":"Cooper","year":"2009","journal-title":"Journal of Zoology"},{"issue":"1","key":"10.7717\/peerj.5923\/ref-11","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1111\/j.1469-7998.1970.tb01259.x","article-title":"The dentition of agamid lizards with special reference to tooth replacement","volume":"162","author":"Cooper","year":"1970","journal-title":"Journal of Zoology"},{"key":"10.7717\/peerj.5923\/ref-12","doi-asserted-by":"publisher","first-page":"247","DOI":"10.1180\/minmag.2008.072.1.247","article-title":"Chemical composition of enamel and dentine in modern reptile teeth","volume":"72","author":"Dauphin","year":"2008","journal-title":"Mineralogical Magazine"},{"key":"10.7717\/peerj.5923\/ref-13","doi-asserted-by":"publisher","first-page":"146","DOI":"10.1002\/jmor.10080","article-title":"Dentition and tooth replacement pattern in Chalcides (Squamata;
