The aim of this study was to compare 2\u2010week splinting versus functional splinting times after surgical extrusion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>Children aged 8\u201013\u00a0years who presented with crown\u2010root fractures were included. Surgical extrusion was performed, and teeth were splinted either for 2\u00a0weeks or until normal Periotest values were achieved (functional splinting time). The outcome measures were tooth mobility, tooth loss, root resorption, marginal bone resorption and ankylosis. Measurements were taken at baseline, weekly after splint removal, and after 1, 3, 6 and 12\u00a0months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Nineteen patients were included in the analysis. Surgically extruded teeth splinted for 2\u00a0weeks showed significantly higher mobility directly after splint removal and at 1\u00a0month after splinting compared with the functional splinting time group. The mean differences for horizontal Periotest values were 14.96 (95% confidence interval: 8.52, 21.39) and 6.63 (95% confidence interval: 0.25, 13), respectively. The vertical Periotest values were 10.47 (95% confidence interval: 1.95, 18.99) and 4.81 (95% confidence interval: \u22121.57, 11.18), respectively. At the 3\u2010, 6\u2010 and 12\u2010month follow\u2010up intervals, there were no statistically significant differences between the groups. One tooth in the 2\u2010week splinting group was lost. None of the teeth had ankylosis, marginal bone resorption or root resorption.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Although both groups showed neither statistical nor clinically significant differences after 12\u00a0months, there was a significant difference immediately after splint removal, with greater tooth mobility in the 2\u2010week splinting group. Thus, a functional splinting time (4\u20106\u00a0weeks) can be suggested for better healing and optimal stability to allow placement of the final restoration directly after splint removal.<\/jats:p><\/jats:sec>","DOI":"10.1111\/edt.12624","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T07:57:02Z","timestamp":1605167822000},"page":"264-274","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effects of different splinting times on surgically extruded teeth with a crown\u2010root fracture: A randomized controlled trial"],"prefix":"10.1111","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2421-3794","authenticated-orcid":false,"given":"Maii","family":"Mohamed","sequence":"first","affiliation":[{"name":"Pediatric Dentistry Department Faculty of Dentistry Cairo University Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dalia","family":"Moheb","sequence":"additional","affiliation":[{"name":"Pediatric Dentistry Department Faculty of Dentistry Cairo University Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nevine","family":"Waly","sequence":"additional","affiliation":[{"name":"Pediatric Dentistry Department Faculty of Dentistry Cairo University Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmad","family":"Abdalsamad","sequence":"additional","affiliation":[{"name":"Department of Oral Radiology Faculty of Dentistry Cairo University Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8343-6501","authenticated-orcid":false,"given":"Ahmed","family":"Elkhadem","sequence":"additional","affiliation":[{"name":"Pediatric Dentistry Department Faculty of Dentistry Cairo University Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.4103\/0976-237X.111603"},{"key":"e_1_2_10_3_1","first-page":"1","article-title":"Clinical evaluation of forceps eruption: reestablishing biologic width and restoring no restorable teeth","volume":"1","author":"Khayat A","year":"2006","journal-title":"Iran Endod J"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.5005\/johcd-3-1-20"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40496-019-00229-2"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-016-1921-1"},{"key":"e_1_2_10_7_1","first-page":"520","article-title":"Orthodontic extrusion in the transitional dentition: a simple technique","volume":"31","author":"Darby LJ","year":"2009","journal-title":"Pediatr Dent"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10024-1753"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12054"},{"key":"e_1_2_10_10_1","first-page":"235","article-title":"Clinical evaluation of intra\u2010alveolar transplantation of teeth with cervical root fractures","volume":"11","author":"Tegsj\u00f6 U","year":"1987","journal-title":"Swed Dent J"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12051"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12438"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2018.02.006"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/edt.12121"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(93)90073-D"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2591.1999.00199.x"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-9657.2002.00118.x"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0722.1977.tb00549.x"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2004.00278.x"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.2006.00480.x"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.11607\/prd.00.0598"},{"key":"e_1_2_10_22_1","first-page":"240","article-title":"Surgical extrusion: a simplified esthetic method of treating non\u2010restorable teeth.
