In the retrospective analysis of 345 mandibular third molars in 189 participants (20% men, 80% women; mean age 20.7 years; standard deviation [SD] \u00b1 0.6), clinical stages of eruption were compared with their radiographic depth in bone, inclination, and root development. Statistics included \u03c72, Mann-Whitney U tests, and logistic regression.\nResults: Significant (p &lt; 0.001) predictor variables for assessing the clinical stage of eruption were radiographic depth in bone and inclination. All teeth radiologically at a depth of the cementoenamel (CE) junction of the neighbouring second molar or deeper were clinically unerupted. Above the CE junction, 80% of vertical and 97% of distoangular teeth were connected to the oral cavity, and 82% of mesioangular and 69% of horizontal teeth were clinically unerupted.\nConclusion: All teeth below or at the CE junction are clinically unerupted. Above the CE junction, stage of eruption should be assessed together with the inclination, but horizontally inclined teeth are recommended to be verified clinically.<\/jats:p>","DOI":"10.2340\/aos.v83.40477","type":"journal-article","created":{"date-parts":[[2024,4,23]],"date-time":"2024-04-23T09:18:17Z","timestamp":1713863897000},"page":"174-179","source":"Crossref","is-referenced-by-count":1,"title":["Assessing current clinical eruption stage of mandibular third molars by dental panoramic radiography"],"prefix":"10.2340","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3460-7009","authenticated-orcid":false,"given":"Tommi","family":"Vesala","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2753-8444","authenticated-orcid":false,"given":"Irja","family":"Vent\u00e4","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8514-5764","authenticated-orcid":false,"given":"Johanna","family":"Sn\u00e4ll","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3938-3232","authenticated-orcid":false,"given":"Magdalena","family":"Marinescu Gava","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7469-9729","authenticated-orcid":false,"given":"Marja","family":"Ekholm","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1183","published-online":{"date-parts":[[2024,4,23]]},"reference":[{"key":"57284","unstructured":"European Commission.
