It is necessary for dental students and dentists to apply their temporomandibular disorders (TMDs)-related knowledge to clinical practice. The current study aimed to evaluate the knowledge and awareness of postgraduate dental students and practicing dentists regarding etiology, diagnosis, and treatment of TMD in western China and thus provide suggestions on TMD curricula design to get postgraduate students and dentists better prepared for TMD diagnosis and treatment. Methods. This observational and descriptive cross-sectional study was conducted among postgraduate students and practicing dentists in western China. Twenty-five reorganized knowledge questions in four domains were selected from the published literature and were evaluated with answer options from \u201cstrongly agree\u201d to \u201cstrongly disagree,\u201d and \u201cI don\u2019t know.\u201d \u201cConsensus\u201d is defined as more than 50% of respondents in a group agree or disagree with a statement. Chi-square tests were performed for comparisons between the two groups. Results. A total of 132 postgraduate dental students and 123 dentists completed the questionnaire. Around 75% of postgraduate students and 85% of dentists claimed that they have never participated in systematic training in TMD. Nine statements in etiology, diagnosis, treatment, and prognosis of TMD had different consensus between the two groups. And the dentist group tended to agree more with 12 statements in the questionnaire. Conclusions. The majority of Chinese dentists and dental students have not taken any TMD courses and possess limited knowledge of TMD. Curriculum reform for predoctoral education, postgraduate education, and continuing education is needed to augment knowledge and skills for TMD diagnosis and treatment.<\/jats:p>","DOI":"10.1155\/2023\/7886248","type":"journal-article","created":{"date-parts":[[2023,7,18]],"date-time":"2023-07-18T20:20:06Z","timestamp":1689711606000},"page":"1-10","source":"Crossref","is-referenced-by-count":25,"title":["Knowledge and Attitudes regarding Temporomandibular Disorders among Postgraduate Dental Students and Practicing Dentists in Western China: A Questionnaire-Based Observational Investigation"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2175-0970","authenticated-orcid":true,"given":"Xin","family":"Xiong","sequence":"first","affiliation":[{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"},{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Temporomandibular Joint, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8259-2569","authenticated-orcid":true,"given":"Chuqiao","family":"Xiao","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Head and Neck Oncology Surgery, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueman","family":"Zhou","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojing","family":"Li","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Temporomandibular Joint, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9040-6295","authenticated-orcid":true,"given":"Jun","family":"Wang","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2283-1959","authenticated-orcid":true,"given":"Yating","family":"Yi","sequence":"additional","affiliation":[{"name":"National Clinical Research Center for Oral Diseases, State Key Laboratory of Oral Diseases, Department of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1177\/0333102416686302"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-020-03710-w"},{"key":"3","volume-title":"The national academies collection: reports funded by national institutes of health Temporomandibular Disorders: Priorities for Research and Care","author":"National Academies of Sciences Engineering Medicine Health","year":"2020"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1080\/08869634.2020.1812816"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1080\/00016357.2016.1196295"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1186\/s12903-020-01259-4"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1002\/jdd.12461"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2018.10.022"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0579.2007.00458.x"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.5114\/pjr.2019.92287"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1053\/joms.2003.50005"},{"issue":"1","key":"12","first-page":"79","article-title":"The research diagnostic criteria for temporomandibular disorders.
