A total of 20 healthy horses, both male and female, with an average age of 9 \u00b1 3 years and weight of 400 \u00b1 100 kg, without a defined breed, were selected. They were divided into two groups: the High Soluble Carbohydrate Group (HSCCG), consisting of 10 horses fed sugarcane for at least 3 years, and the Low Soluble Carbohydrate Group (LSCCG), consisting of 10 horses fed pasture with Cynodon spp. Dental examinations were performed using an adapted oral endoscope to assess caries and diastemata, and saliva samples were collected for microbiota analysis. Statistical analyses included a Student\u2019s t-test and Mann\u2013Whitney test, with significance set at p &lt; 0.05. Horses in the HSCCG had a higher presence of peripheral caries (p = 0.001), as well as differences in the degree (p = 0.010), class (p = 0.05), and presence of diastemata. Microbial diversity indices (Chao, inverse Simpson, and Shannon) showed no significant differences, but the relative abundance differed (p = 0.003). Linear Discriminant Analysis revealed distinct microbial profiles: Candidatus Saccharibacteria and Bacteroidetes were more abundant in the HSCCG, while Cyanobacteria_Chloroplast and Proteobacteria dominated in the LSCCG. Over 35 genera differed significantly between groups. The study concludes that diet plays a significant role in shaping oral microbiota and influencing the development of dental caries in horses.<\/jats:p>","DOI":"10.3390\/ani15172547","type":"journal-article","created":{"date-parts":[[2025,8,29]],"date-time":"2025-08-29T16:18:15Z","timestamp":1756484295000},"page":"2547","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Microbiome and Dental Changes in Horses Fed a High Soluble Carbohydrate Diet"],"prefix":"10.3390","volume":"15","author":[{"given":"Milena Domingues","family":"Lacerenza","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, School of Animal Science and Food Engineering, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00falia de Assis","family":"Arantes","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, School of Animal Science and Food Engineering, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustavo Morandini","family":"Reginato","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, School of Animal Science and Food Engineering, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela Luiza Fagundes","family":"Finardi","sequence":"additional","affiliation":[{"name":"Pet Nutrology Research Center (CEPEN Pet), Department of Animal Nutrition and Production, School of Veterinary Medicine and Animal Science, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0103-8785","authenticated-orcid":false,"given":"Pedro Henrique","family":"Marchi","sequence":"additional","affiliation":[{"name":"Pet Nutrology Research Center (CEPEN Pet), Department of Animal Nutrition and Production, School of Veterinary Medicine and Animal Science, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4457-8392","authenticated-orcid":false,"given":"Thiago Henrique Annibale","family":"Vendramini","sequence":"additional","affiliation":[{"name":"Pet Nutrology Research Center (CEPEN Pet), Department of Animal Nutrition and Production, School of Veterinary Medicine and Animal Science, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Romero","family":"Corr\u00eaa","sequence":"additional","affiliation":[{"name":"Teaching and Research Support Center (CAEP), School of Veterinary Medicine and Animal Science, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5832-7944","authenticated-orcid":false,"given":"Pamela Aparecida Maldaner","family":"Pereira","sequence":"additional","affiliation":[{"name":"Faculty of Agricultural and Veterinary Sciences, Sao Paulo State University, Jaboticabal 14884-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5283-7310","authenticated-orcid":false,"given":"Carlos Augusto Ara\u00fajo","family":"Valad\u00e3o","sequence":"additional","affiliation":[{"name":"Faculty of Agricultural and Veterinary Sciences, Sao Paulo State University, Jaboticabal 14884-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4275-0358","authenticated-orcid":false,"given":"Renata Gebara Sampaio","family":"D\u00f3ria","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, School of Animal Science and Food Engineering, University of Sao Paulo, Pirassununga 13635-900, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,29]]},"reference":[{"key":"ref_1","first-page":"e161","article-title":"Equine peripheral cemental defects and dental caries: Four case reports","volume":"33","author":"Birkhed","year":"2020","journal-title":"Equine Vet.
