Ninety\u2010three needles of a single brand were collected from a group of eleven similarly trained Australian dentists\u2019 following either single or dual insertion and bone contact. Specimens were examined under scanning electron microscopy at 500x, and both the direction of deformation (either towards or away from lumen) and the extent of deformation were calculated using image processing software. Results showed no correlation between bevel orientation and either the direction (<jats:italic>P\u00a0<\/jats:italic>=\u00a00.8787) or degree (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.0752) of deformation. Significance was demonstrated, regardless of bevel orientation, following multiple needle use with respect to extent of needle tip deformation (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.0001). A clinical recommendation can be made that the dental needle should be routinely replaced when subsequent injections are required during the delivery of a typical IANB.<\/jats:p>","DOI":"10.1111\/aej.12361","type":"journal-article","created":{"date-parts":[[2019,7,4]],"date-time":"2019-07-04T02:14:36Z","timestamp":1562206476000},"page":"325-330","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Evaluation of bevelled needle tip deformation with Dental Inferior Alveolar Nerve blocks"],"prefix":"10.1111","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0401-9908","authenticated-orcid":false,"given":"Tony","family":"Skapetis","sequence":"first","affiliation":[{"name":"Faculty of Medicine &amp; Health Sydney Dental School Clin A\/Prof University of Sydney Westmead Centre for Oral Health, WSLHD Westmead NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phuong Diem","family":"Doan\u2010Tran","sequence":"additional","affiliation":[{"name":"Faculty of Medicine &amp; Health Sydney Dental School University of Sydney Sydney NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nibir M.","family":"Hossain","sequence":"additional","affiliation":[{"name":"Faculty of Medicine &amp; Health Sydney Dental School University of Sydney Sydney NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,7,3]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.1994.0233"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004770-200310000-00004"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.4236\/mr.2015.31001"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.12968\/denu.2003.30.7.370"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.2000.0308"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.2006.0114"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2017.06.013"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1834-7819.2011.01312.x"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(94)90315-8"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-7580.1998.19220233.x"},{"key":"e_1_2_9_12_1","first-page":"317","article-title":"Comparison of two needle models in terms of bevel deformation during truncal block of the inferior alveolar nerve","volume":"12","author":"Almendros Marqu\u00e9s N","year":"2007","journal-title":"Med Oral Patol Oral Cir Bucal"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-7580.1998.19220245.x"}],"container-title":["Australian Endodontic Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/aej.12361","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/aej.12361","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/aej.12361","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,8]],"date-time":"2023-09-08T18:56:12Z","timestamp":1694199372000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/aej.12361"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,3]]},"references-count":12,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2019,12]]}},"alternative-id":["10.1111\/aej.12361"],"URL":"https:\/\/doi.org\/10.1111\/aej.12361","archive":["Portico"],"relation":{},"ISSN":["1329-1947","1747-4477"],"issn-type":[{"value":"1329-1947","type":"print"},{"value":"1747-4477","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,7,3]]},"assertion":[{"value":"2019-07-03","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
