Additionally, M3 development in relation to patients\u2019 age and gender was investigated. Panoramic radiographs of non-syndromic patients with at least one congenitally absent PM2 were used to assess the localization and number of missing PM2 and the presence or absence of M3 (minimum age 10 years). The alternate logistic regression model was applied to analyze associations between the presence of PM2 and M3. A total of 131 patients with PM2 agenesis were identified (82 females, 49 males). At least one M3 was present in 75.6% and all M3 were present in 42.7% of patients. A statistically significant association between the number of PM2 and M3 agenesis was found; the effects of age and gender were not significant. More than half of M3 in patients between 14\u201317 years old had completed \u00bc of their root development. The congenital absence of maxillary PM2 was associated with the absence of maxillary PM2, M3, and no correlation was found in the mandible. In patients with PM2 agenesis, at least one M3 is often present and can be considered as a donor tooth for autotransplantation.<\/jats:p>","DOI":"10.3390\/diagnostics13111874","type":"journal-article","created":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T16:16:04Z","timestamp":1685204164000},"page":"1874","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Availability of Third Molars as Donor Teeth for Autotransplantation to Replace Congenitally  Absent Second Premolars in Children and Young Adults"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1037-9742","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Bili\u0144ska","sequence":"first","affiliation":[{"name":"Private Practice, 02-916 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Burzykowski","sequence":"additional","affiliation":[{"name":"Data Science Institute, Hasselt University, 3500 Hasselt, Belgium"},{"name":"Department of Statistics and Medical Informatics, Medical University of Bialystok, 15-295 Bia\u0142ystok, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4713-2142","authenticated-orcid":false,"given":"Pawe\u0142","family":"Plakwicz","sequence":"additional","affiliation":[{"name":"Department of Periodontology, Medical University in Warsaw, 02-097 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Zadurska","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Medical University in Warsaw, 02-097 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1009-6483","authenticated-orcid":false,"given":"Ewa Monika","family":"Czochrowska","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Medical University in Warsaw, 02-097 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,27]]},"reference":[{"key":"ref_1","first-page":"113","article-title":"Radiographic study of prevalence and distribution of hypodontia in a pediatric orthodontic population in Venezuela","volume":"34","author":"Medina","year":"2012","journal-title":"Pediatr.
