In total, 43 sites of 15 teeth were randomly chosen, and marginal bone loss was measured twice in all protocols at 43 sites of 15 teeth by one calibrated investigator. Bland-Altman plots and Lin\u2019s concordance correlation coefficient (CCC) were calculated to assess the extent of agreement of the measurements. Additionally, the rater scored the certainty in each of the measurements.\nResults: For HD-CBCT CCC of measurements obtained using SV versus LV was 0.991. CCC of measurements obtained using SV versus LV of LD-CBCT was 0.963. Both CCC values indicated excellent agreement between the two volumes in both protocols.\u00a0\nCCC also indicated high intramodality correlation between HD-CBCT and LD-CBCT independent of the acquisition volume (0.963 \u2013 0.992). Bland-Altman plots also indicated no substantial differences. Results of certainty scoring showed significant differences (p = 0.004 (LV), p &lt; 0.001(SV)) between the LD and HD-CBCT.\nConclusions: Accuracy of measurements of bone loss shows no clinical noticeable effects depending on the CBCT volume in this ex vivo study. There appears to be no relevant advantage of SV over LV, neither in HD-CBCT nor in LD-CBCT and additionally no relevant advantage of HD versus LD in visualizing marginal bone loss.<\/jats:p>","DOI":"10.2340\/aos.v83.40494","type":"journal-article","created":{"date-parts":[[2024,4,25]],"date-time":"2024-04-25T11:44:47Z","timestamp":1714045487000},"page":"204-209","source":"Crossref","is-referenced-by-count":1,"title":["Impact of acquisition volume on cone beam computed tomography imaging of marginal bone: an ex vivo study"],"prefix":"10.2340","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9945-7286","authenticated-orcid":false,"given":"Maurice","family":"Ruetters","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Korallia","family":"Alexandrou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Holger","family":"Gehrig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sinclair","family":"Awounvo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ti-Sun","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Felten","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Lux","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sinan","family":"Sen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2024,4,25]]},"reference":[{"key":"57671","doi-asserted-by":"crossref","unstructured":"Ludlow JB, Timothy R, Walker C, et al.
