Sixteen patients treated an for impacted mandibular wisdom tooth at least one year ago were re-called (18 teeth). Dental panoramic tomography and periodontal parameters were assessed. A graft material was used to fill the post-extractive sockets in the test group (GUIDOR easy-graft CRYSTAL), whereas in the control group, the socket was filled using a collagen sponge and blood clot (Hemocollagene, Septodont, Matar\u00f2, Spain). The radiographic bone loss was measured at the distal aspect of the second molar. The Wilcoxon singed-rank test for paired data was performed to evaluate statistical differences. In the test group, only two cases out of nine showed bone loss, with an average of 0.55 \u00b1 1.30 mm. Conversely, in the control group, five teeth out of nine showed bone resorption with an average of 1.22 \u00b1 1.30 mm. However, the differences were not statistically significant. Periodontal parameters at the second molar demonstrated similar behavior between the test and control groups. Soft tissue healing complications were lower in the grafted compared to the comparator sites without reaching statistical significance. Within the limitations of the present study, no difference was found between the two groups.<\/jats:p>","DOI":"10.3390\/ma14112844","type":"journal-article","created":{"date-parts":[[2021,5,26]],"date-time":"2021-05-26T10:30:32Z","timestamp":1622025032000},"page":"2844","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Pilot Retrospective Study on the Effect of Bone Grafting after Wisdom Teeth Extraction"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9875-2929","authenticated-orcid":false,"given":"Luigi","family":"Canullo","sequence":"first","affiliation":[{"name":"Department of Periodontology, University of Bern, 3000 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giampiero","family":"Rossi-Fedele","sequence":"additional","affiliation":[{"name":"Adelaide Dental School, The University of Adelaide, Adelaide, SA 5000, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Camodeca","sequence":"additional","affiliation":[{"name":"Private Practice, 00198 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6503-1201","authenticated-orcid":false,"given":"Maria","family":"Menini","sequence":"additional","affiliation":[{"name":"Department of Surgical Sciences and Integrated Diagnostics, University of Genoa, 16100 Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8726-4145","authenticated-orcid":false,"given":"Paolo","family":"Pesce","sequence":"additional","affiliation":[{"name":"Department of Surgical Sciences and Integrated Diagnostics, University of Genoa, 16100 Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/j.joms.2010.10.011","article-title":"The Incidence of Periodontal Defects Distal to the Maxillary Second Molar After Impacted Third Molar Extraction","volume":"69","author":"Coleman","year":"2011","journal-title":"J.
