A total of 73 premolar roots from four male mongrel dogs were intentionally avulsed with forceps and divided into four groups\u2014HN, HL, DN, and DL\u2014according to storage conditions and whether or not they received LIPUS treatment. Thirty-eight roots were kept in Hanks\u2019 Balanced Salt Solution for 30\u00a0min (HN and HL groups), whereas the remaining 35 roots were left to dry in the air for an hour (DN and DL groups) prior to replantation. Following replantation, the roots in the HL and DL groups (21 and 18 roots, respectively) received a 20-min daily LIPUS treatment for 2\u00a0weeks. The animals were euthanized 4\u00a0weeks after the operation. Micro-computed tomography images were acquired for each root and the amount of replacement root resorption was measured three-dimensionally. Histological assessments were also carried out. There was significantly less replacement root resorption for the roots in the DL group compared to the DN group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). Histological findings in the DN group demonstrated evident replacement root resorption, whereas the DL group revealed less severe resorption compared to the DN group. Within the limitations, these results suggest that LIPUS could attenuate the replacement resorption of avulsed teeth stored in a\u00a0dry condition, thereby improving their prognosis.<\/jats:p>","DOI":"10.1038\/s41598-021-92471-x","type":"journal-article","created":{"date-parts":[[2021,6,18]],"date-time":"2021-06-18T10:03:33Z","timestamp":1624010613000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Low-intensity pulsed ultrasound attenuates replacement root resorption of avulsed teeth stored in dry condition in dogs"],"prefix":"10.1038","volume":"11","author":[{"given":"Saemi","family":"Seong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dohyun","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dasun","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyung-Ryong","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yooseok","family":"Shin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,6,18]]},"reference":[{"key":"92471_CR1","volume-title":"Textbook and Color Atlas of Traumatic Injuries to the Teeth","author":"JO Andreasen","year":"2018","unstructured":"Andreasen, J.
