Control image: symmetric (parallelism between occlusal plane (OP), commissural line (CL), and interpupillary line (IL)). Change of Control, obtaining three images with a 3-degree inclination of the labial commissures. Image A: OP parallel to IL; Image B: OP parallel to CL; Image C: OP at 1.5 degree mean angulation between IL and CL. Non-parametric comparison (IBM\u00a9 SPSS Statistics vs. 27.0, p &lt; 0.05). The \u201cDentists\u201d group\u2019s decreasing order of preference (attractiveness) of the images is: Control &gt; A &gt; C &gt; B (p &lt; 0.05). In the \u201cLay\u201d group, it is: Control &gt; A &gt; (C not \u2260 B). Dentists significantly prefer more the Control and Image A than laypeople (p &lt; 0.001). Sex (single exception in laypeople), age, and dentist\u2019s area of activity did not interfere in the perception of attractiveness. Dentists and laypeople preferred the Control when compared to images with CL canted. In the existence of CL inclination, the preference of the groups was the IL as a reference for OP orientation, with the mean angulation or coincident with the CL being considered less aesthetic.<\/jats:p>","DOI":"10.3390\/ijerph182212258","type":"journal-article","created":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T02:55:17Z","timestamp":1637636117000},"page":"12258","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Aesthetic Preference in the Transverse Orientation of the Occlusal Plane in Rehabilitation: Perspective of Laypeople and Dentists"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0015-4400","authenticated-orcid":false,"given":"Ana Lidia","family":"Carvalho","sequence":"first","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4372-7309","authenticated-orcid":false,"given":"Liliana Gavinha","family":"Costa","sequence":"additional","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"}]},{"given":"Joana Meneses","family":"Martins","sequence":"additional","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1774-1337","authenticated-orcid":false,"given":"Maria Concei\u00e7\u00e3o","family":"Manso","sequence":"additional","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"},{"name":"FP-I3ID, Instituto de Investiga\u00e7\u00e3o, Inova\u00e7\u00e3o e Desenvolvimento, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2430-1241","authenticated-orcid":false,"given":"Sandra","family":"Gavinha","sequence":"additional","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"}]},{"given":"Mariano","family":"Herrero-Climent","sequence":"additional","affiliation":[{"name":"Porto Dental Institute, 4150-518 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2832-5902","authenticated-orcid":false,"given":"Blanca","family":"R\u00edos-Carrasco","sequence":"additional","affiliation":[{"name":"Department of Periodontology, Universidad de Sevilla, 41009 Seville, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8031-6176","authenticated-orcid":false,"given":"Carlos","family":"Falc\u00e3o","sequence":"additional","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"},{"name":"Porto Dental Institute, 4150-518 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1089-279X","authenticated-orcid":false,"given":"Paulo","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"FP-I3ID, FCS, Universidade Fernando Pessoa, 4249-004 Porto, Portugal"},{"name":"Porto Dental Institute, 4150-518 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"482","DOI":"10.1016\/j.prosdent.2019.01.023","article-title":"Perception of occlusal plane that is nonparallel to interpupillary and commissural lines but with the maxillary dental midline ideally positioned","volume":"122","author":"Meyer","year":"2019","journal-title":"J.
