In Chile, national data from 2007 reported significant inequities in dental caries among six-year-old children, with higher prevalence in rural and low-income areas. This study aimed to evaluate socioeconomic inequalities in the distribution of dental caries among Chilean children aged 6\u00a0years from 2008 to 2023, considering recent public health interventions. This ecological study utilized anonymized routine health records from the Chilean public health system and socioeconomic data at the municipal level, covering 2008\u20132023, with data from up to n = 323 municipalities nationwide. Caries experience was measured as the proportion of six-year-old children with decayed, extracted, or filled primary teeth (dmft &gt; 0) per municipality and year, following WHO criteria. Socioeconomic inequalities were assessed using the Slope Index of Inequality (SII) and Relative Index of Inequality (RII), with linear regression models to evaluate trends over time. A reduction in caries experience among six-year-old children \u2013 decreasing from 75.8% in 2008\u20132011 to 60.4% in 2020\u20132023 \u2013 was observed. Absolute inequality in caries experience between the least and most advantaged groups declined from 14.9% in 2008\u20132011 to 9.5% in 2020\u20132023. However, profound socioeconomic inequities in caries distribution persisted throughout the study period. The findings indicate a trend towards reduced socioeconomic inequalities in dental caries among six-year-old Chilean children, possibly influenced by preventive public health programs. Nevertheless, significant inequities and high caries levels remain, highlighting the need for sustained and equitable oral health interventions.<\/jats:p>","DOI":"10.1177\/0265539x251369459","type":"journal-article","created":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T14:06:26Z","timestamp":1756303586000},"page":"120-126","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of socioeconomic inequalities in dental caries levels in Chilean children aged 6 years, 2008\u20132023"],"prefix":"10.1177","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7562-1384","authenticated-orcid":false,"given":"Andr\u00e9s","family":"Celis","sequence":"first","affiliation":[{"name":"Universidad de los Andes"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Meleda","sequence":"additional","affiliation":[{"name":"Universidad de los Andes"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonia","family":"P\u00e9rez","sequence":"additional","affiliation":[{"name":"Universidad de los Andes"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Celis-Dooner","sequence":"additional","affiliation":[{"name":"Universidad de los Andes"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duniel","family":"Ortuno Borroto","sequence":"additional","affiliation":[{"name":"Universidad de los Andes"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,8,27]]},"reference":[{"key":"e_1_3_6_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034520908533"},{"key":"e_1_3_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/cdoe.12701"},{"key":"e_1_3_6_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/children9020262"},{"key":"e_1_3_6_5_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2025.1546317"},{"key":"e_1_3_6_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyac191"},{"key":"e_1_3_6_7_1","volume-title":"National Child Oral Health Improvement Programmes for Chile","author":"Celis Sersen AO","year":"2022","unstructured":"Celis Sersen AO, McMahon A (2022) National Child Oral Health Improvement Programmes for Chile [Data Collection].
