The aim of this cross-sectional clinical study was to determine whether visual impairment influences shade selection using two methods: spectrophotometry and shade guides. Materials and Methods: The sample consisted of 2796 maxillary and mandibular teeth, and shade selection was measured subjectively with a shade guide (VITA Classic, VITA Zahnfabrik) and objectively with a spectrophotometer (VITA Easyshade\u00ae V, VITA Zahnfabrik, Bad S\u00e4ckingen, Germany). In all cases, three measurements were taken on each tooth, with a waiting time of 15 min between samples. Shade selection was compared between observers with normal vision, myopia, astigmatism, and hyperopia. Results: The results show that myopic subjects perceived the lower central incisors (2.63, p &lt; 0.05), upper lateral incisors (2.42, p &lt; 0.05), lower lateral incisors (2.34, p &lt; 0.05), and lower canines (2.64, p &lt; 0.05) more clearly. Non-astigmatic subjects perceived the lower second premolar as lighter than astigmatic subjects (\u22122.01, p &lt; 0.05). Conclusions: It can be concluded that myopes see teeth more clearly, but no differences have been found in astigmatism and hyperopes.<\/jats:p>","DOI":"10.3390\/jcm14010293","type":"journal-article","created":{"date-parts":[[2025,1,6]],"date-time":"2025-01-06T10:40:52Z","timestamp":1736160052000},"page":"293","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Impact of Vision Defects on Tooth Shade Selection: A Comparative of Spectrophotometry and Shade Guides in a Cross-Sectional Clinical Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6615-5134","authenticated-orcid":false,"given":"Mario","family":"Alvarado-Lorenzo","sequence":"first","affiliation":[{"name":"Department of Dentistry, Universidad Cat\u00f3lica San Antonio de Murcia, 30107 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Lozano-Garcia","sequence":"additional","affiliation":[{"name":"Department of Health Science, Miguel de Cervantes European University of Valladolid, 47012 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8882-2794","authenticated-orcid":false,"given":"Pedro","family":"Colino-Gallardo","sequence":"additional","affiliation":[{"name":"Department of Dentistry, Universidad Cat\u00f3lica San Antonio de Murcia, 30107 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis Daniel","family":"Pellicer Castillo","sequence":"additional","affiliation":[{"name":"Department of Health Science, Miguel de Cervantes European University of Valladolid, 47012 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6141-0546","authenticated-orcid":false,"given":"Victor","family":"D\u00edaz-Flores Garc\u00eda","sequence":"additional","affiliation":[{"name":"Department of Cl\u00ednical Denstistry, University European of Madrid, Madrid, 28670 Vilaviciosa de Od\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8314-9692","authenticated-orcid":false,"given":"Alfonso","family":"Alvarado-Lorenzo","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Universidad de Salamanca, 37007 Salamanca, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,6]]},"reference":[{"key":"ref_1","unstructured":"Dudkiewicz, K., \u0141acinik, S., Jedli\u0144ski, M., Janiszewska-Olszowska, J., and Grocholewicz, K.
