We hypothesized that mandibular anterior crowding may be related to abnormalities in the development of oral function. To determine the relationship between oral function and mandibular anterior crowding in early mixed dentition. A total of 61 children (30 boys, 31 girls) with early mixed dentition were included in this study. Height, body weight, maximum occlusal force, lip\u2010closing strength, and maximum tongue pressure were measured in all participants, and their dental casts and lateral cephalograms were evaluated. Little's irregularity index (LII), evaluated by dental casts, was used as an indicator of mandibular anterior crowding. Maximum occlusal force and lip\u2010closing strength were not significantly correlated with the LII, although they were positively correlated with maximum tongue pressure, mandibular intercanine perimeter distance, and upper central incisor (U1)\u2010to\u2010NL angle (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Maximum tongue pressure was negatively correlated with LII (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Maximum tongue pressure and LII were significantly positively correlated with the mandibular intercanine perimeter distance and U1\/NL angle, and negatively correlated with the interincisal angle (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05 for all). Crowding of the mandibular anterior teeth was directly correlated with tongue pressure function and indirectly correlated with maximum occlusal force and lip\u2010closing strength.<\/jats:p>","DOI":"10.1002\/cre2.306","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T01:23:45Z","timestamp":1593566625000},"page":"529-536","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Relationship between oral function and mandibular anterior crowding in early mixed dentition"],"prefix":"10.1002","volume":"6","author":[{"given":"Yoma","family":"Ohno","sequence":"first","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science, Department of Health Promotion Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5803-0742","authenticated-orcid":false,"given":"Yuko","family":"Fujita","sequence":"additional","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science, Department of Health Promotion Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keirato","family":"Ohno","sequence":"additional","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science, Department of Health Promotion Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenshi","family":"Maki","sequence":"additional","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science, Department of Health Promotion Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","first-page":"494","DOI":"10.1016\/j.ortho.2014.10.001","article-title":"The relationship between molar bite force and incisor inclination: A prospective cross\u2010sectional study","volume":"12","author":"Alabdullah M.
