Therefore, it is important to evaluate the learning curve of dentists undergoing surgical training. Thus, the aims of this study were to assess the performance of oral surgery residents in third molar extractions based on operative time and the occurrence of incidents\/complications, and to determine which variables are associated with surgical difficulty.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and Methods<\/jats:title>\n                    <jats:p>A prospective cohort study was carried out in adults requiring an impacted lower third molar extraction. All procedures were performed by residents of a master's degree in Oral Surgery and Implantology. The outcome variables were operative time and surgeon\u2010reported difficulty. A descriptive, bivariate and multivariate analysis was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>One hundred and 74 patients were operated on by six students. Similar performance was observed among the surgeons. Although a significant improvement in operative time was seen after 10 cases, a non\u2010significant decreasing trend of incidents was also found. The multivariate analysis revealed an association between difficulty with crown\/root sectioning and impaction against the second molar.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>At least 10 lower impacted third molar extractions performed by postgraduate students with experience in tooth extractions are required to improve the operative time. Incidents seem to decrease slightly with the number of procedures performed. Surgical difficulty seems to be related to the need for crown\/tooth sectioning and greater impaction against the second molar. Further studies are required to confirm these findings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/eje.13066","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T03:41:17Z","timestamp":1737430877000},"page":"266-276","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Learning Curve in the Extraction of Impacted Lower Third Molars: A Prospective Cohort Study"],"prefix":"10.1111","volume":"29","author":[{"given":"Alba","family":"S\u00e1nchez\u2010Torres","sequence":"first","affiliation":[{"name":"Facultat de Medicina i Ci\u00e8ncies de la Salut Universitat de Barcelona  Barcelona Spain"},{"name":"Institut d'Investigaci\u00f3 Biom\u00e8dica de Bellvitge  L'Hospitalet de Llobregat Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eliana","family":"Sabreen","sequence":"additional","affiliation":[{"name":"Facultat de Medicina i Ci\u00e8ncies de la Salut Universitat de Barcelona  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xavier","family":"Arias\u2010Huerta","sequence":"additional","affiliation":[{"name":"Facultat de Medicina i Ci\u00e8ncies de la Salut Universitat de Barcelona  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Octavi","family":"Camps\u2010Font","sequence":"additional","affiliation":[{"name":"Facultat de Medicina i Ci\u00e8ncies de la Salut Universitat de Barcelona  Barcelona Spain"},{"name":"Institut d'Investigaci\u00f3 Biom\u00e8dica de Bellvitge  L'Hospitalet de Llobregat Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2122-6530","authenticated-orcid":false,"given":"Rui","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"Facultat de Medicina i Ci\u00e8ncies de la Salut Universitat de Barcelona  Barcelona Spain"},{"name":"Institut d'Investigaci\u00f3 Biom\u00e8dica de Bellvitge  L'Hospitalet de Llobregat Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduard","family":"Valmaseda\u2010Castell\u00f3n","sequence":"additional","affiliation":[{"name":"Facultat de Medicina i Ci\u00e8ncies de la Salut Universitat de Barcelona  Barcelona Spain"},{"name":"Institut d'Investigaci\u00f3 Biom\u00e8dica de Bellvitge  L'Hospitalet de Llobregat Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cosme","family":"Gay\u2010Escoda","sequence":"additional","affiliation":[{"name":"Institut d'Investigaci\u00f3 Biom\u00e8dica de Bellvitge  L'Hospitalet de Llobregat Spain"},{"name":"Centro M\u00e9dico Teknon  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2004.04891.x"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000156470.79032.7B"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/2192568219880872"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.4321\/S0004-06142007000400013"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.asjsur.2014.05.002"},{"issue":"435","key":"e_1_2_9_7_1","first-page":"438","article-title":"Laparoscopic Cholecystectomy and Outpatient Surgery","volume":"96","author":"Rico Selas P.","year":"2004","journal-title":"Revista Espa\u00f1ola de Enfermedades Digestivas"},{"key":"e_1_2_9_8_1","first-page":"1","article-title":"Mandibular Third Molar Impaction: Review of Literature and a Proposal of a Classification","volume":"4","author":"Joudzbalys G.","year":"2013","journal-title":"Journal of Oral & Maxillofacial Research"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.4317\/medoral.15.e869"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1308\/204268513X13776914744718"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.2012.780"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2004.05.214"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2012.08.004"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0278-2391(86)90221-1"},{"key":"e_1_2_9_15_1","first-page":"779","article-title":"Complications After Mandibular Third Molar Extraction","volume":"26","author":"Boer M.
