A population-based, cross-sectional survey was conducted in 28 cities at social risk in Northeast Brazil. All permanent residents aged 12, 15\u201319, 35\u201344, and 65\u201374 years were eligible, and 3063 were included. Participants answered a questionnaire on socioeconomic status, beliefs, and behaviors. Trained local dentists performed oral clinical examinations during home visits. Caries and tooth loss were evaluated using the decayed, missing, and filled teeth (DMFT) index and OHRQoL was evaluated using the Oral Health Impact Profile-14 (OHIP-14). Poisson regression analysis was performed to assess the relationship between individual domains, OHIP-14 scores, dental caries, tooth loss, and socioeconomic\/demographic characteristics. Mean DMFT (standard deviation) scores were 2.68 (4.01), 4.84 (4.30), 15.35 (7.26), and 26.72 (8.03) for groups aged 12, 15\u201319, 35\u201344, and 65\u201374 years, respectively. Most participants (70%) were partially edentulous and 13% were completely edentulous. Caries and tooth loss significantly increased with age and impacted OHRQoL. Physical pain (5.8%) and psychological discomfort (5.8%) were the most commonly reported on the OHIP-14. Untreated caries (prevalence ratio (PR), 1.54; 95% confidence interval (CI), 1.37\u20131.72) and edentulism (PR, 1.29; 95% CI, 1.08\u20131.53) had a significant negative impact on OHRQoL. Income, level of education, sex, age, and oral hygiene habits were also related to OHRQoL. There was a high prevalence of dental caries and edentulism in all age groups except 12-year-olds. OHRQoL was negatively impacted by these oral conditions across the lifespan, with a trend towards more negative scores and higher impact in older adults.<\/jats:p>","DOI":"10.3390\/ijerph20176661","type":"journal-article","created":{"date-parts":[[2023,8,28]],"date-time":"2023-08-28T06:10:22Z","timestamp":1693203022000},"page":"6661","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Dental Caries, Tooth Loss and Quality of Life of Individuals Exposed to Social Risk Factors in Northeast Brazil"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7448-7868","authenticated-orcid":false,"given":"Lu\u00edsa Sim\u00f5es","family":"de Albuquerque","sequence":"first","affiliation":[{"name":"Department of Clinical and Community Dentistry, Health Science Center, Federal University of Para\u00edba, Jo\u00e3o Pessoa 58051-900, PB, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raiana Gurgel","family":"de Queiroz","sequence":"additional","affiliation":[{"name":"Department of Clinical and Community Dentistry, Health Science Center, Federal University of Para\u00edba, Jo\u00e3o Pessoa 58051-900, PB, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenny","family":"Abanto","sequence":"additional","affiliation":[{"name":"Internacional University of Catalunya, Catalunya, 08017 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo Jos\u00e9","family":"Strazzeri B\u00f6necker","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo 05508-220, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4237-0184","authenticated-orcid":false,"given":"Franklin Delano","family":"Soares Forte","sequence":"additional","affiliation":[{"name":"Department of Clinical and Community Dentistry, Health Science Center, Federal University of Para\u00edba, Jo\u00e3o Pessoa 58051-900, PB, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F\u00e1bio Correia","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Department of Clinical and Community Dentistry, Health Science Center, Federal University of Para\u00edba, Jo\u00e3o Pessoa 58051-900, PB, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"592","DOI":"10.1177\/0022034513490168","article-title":"Global burden of oral conditions in 1990\u20132010: A systematic analysis","volume":"92","author":"Marcenes","year":"2013","journal-title":"J.
