Demographic information, Fonseca Anamnestic Index (FAI), Smartphone Addiction Scale-Short Version (SAS-SV), and Patient Health Questionnaire-4 (PHQ-4) responses were gathered electronically and analyzed using multiple logistic regression analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 163 male and 307 female respondents were participated in this study. The prevalence of PSU and TMD were 83.6% and 66.4%, respectively. There was a moderate statistical correlation between PSU and TMD among young adults (<jats:italic>r<\/jats:italic> = 0.31, <jats:italic>p<\/jats:italic> &amp;lt; 0.01). The logistic regression model revealed that the risk of TMD was 1.77 times higher in people with PSU than in those without PSU (OR = 1.77; 95% CI 1.04\u20133.06). PSU is a risk factor for pain-related TMD (OR = 1.81; 95% CI 1.08\u20133.04) but not intra-articular TMD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Subjects showed high prevalence of both TMD and PSU. People with PSU experienced more severe and frequent pain-related rather than intra-articular TMD symptoms than those without PSU. By reducing the problematic smartphone use, the risk factor of TMD might be avoided.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2022.1042147","type":"journal-article","created":{"date-parts":[[2022,12,23]],"date-time":"2022-12-23T05:16:21Z","timestamp":1671772581000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["The
