The protocol was registered in the international prospective database of systematic reviews (PROSPERO) (CRD42024521564). The risk of bias in the included studies was assessed by using the Joanna Briggs Institute (JBI) checklist. Two reviewers performed an electronic search on the Web of Science, Scopus, PubMed, and Embase databases for articles published up to the end of 2023.RESULTSThe electronic search resulted in 406 studies. After removing duplicates, 205 studies remained. Thirty-one studies (30 in vitro and 1 in vivo) were included and categorized into 6 types: AM material (type and composition), prosthetic factor (tooth type, restoration size, finish line, abutment taper), AM system (technique and printer), AM parameters (layer thickness, printing orientation), postprocessing (rinsing, postpolymerization), and aging.CONCLUSIONSThe accuracy of AM interim dental prostheses is affected by factors that include the AM material, prosthetic factors, the AM system, the AM parameters, postprocessing, and aging.","PeriodicalId":501672,"journal":{"name":"The Journal of Prosthetic Dentistry","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142261076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey produced complete data on dentition examination, dietary intakes, and self-reported migraine or severe headaches. Weighted multivariable logistic regression analyses were performed (α=.05).RESULTSA total of 20.28% of the participants had migraine or severe headaches. After adjusting demographic, clinical, and dietary covariates, the total number of missing teeth was not significantly associated with migraine or severe headaches, and only having both anterior and posterior missing teeth was significantly associated with migraine or severe headaches. The odds ratio (OR) and confidence interval (CI) was 1.32(1.09, 1.60) (P=.007). A significantly positive correlation was found between the number of unreplaced missing teeth and migraine or severe headaches. An increase of 1 in the number of unreplaced missing teeth was associated with a 3% increase in migraine or severe headaches (OR and CI: 1.03(1.01, 1.06), P=.012). However, no significant relationship was found between replaced missing teeth and migraine or severe headaches (OR and CI: 1.00(0.99, 1.01), P=.800). Furthermore, unreplaced missing posterior teeth and both unreplaced anterior and posterior teeth were significantly related with more migraine or severe headaches, but no significant association of unreplaced teeth was found with migraine or severe headaches only in the anterior zone in the adjusted model (OR and CI: anterior teeth unreplaced: 0.90(0.43, 1.88), P=.800; posterior teeth unreplaced: 1.14(1.00, 1.30), P=.047; both anterior and posterior teeth unreplaced: 1.61(1.16, 2.22), P=.007). Because of the important association between posterior missing teeth and migraine or severe headaches, further analyses found a 1 tooth increase in unreplaced posterior teeth was related to a 4% increment in migraine or severe headaches (OR and CI: 1.04(1.01, 1.07), P=.017); however, the number of replaced posterior teeth was not associated with migraine or severe headaches (OR and CI: 1.00(0.99, 1.02), P=.900).CONCLUSIONSThe number of unreplaced missing posterior teeth was positively associated with migraine or severe headaches, while missing but restored posterior teeth were not associated with migraine or severe headaches in a US population.","PeriodicalId":501672,"journal":{"name":"The Journal of Prosthetic Dentistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
