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}

The purpose of this systematic review and meta-analysis was to evaluate the effect of various substrates, including enamel, dentin, or an existing composite resin restoration, on the clinical survival and complication rates of ceramic veneers. The PubMed, Scopus, and the Cochrane Library electronic databases were searched, and related journals were hand searched without time or language restrictions to identify clinical trials that compared the survival rate and clinical complication rates when bonding ceramic veneers to different tooth substrates. The success rate of the included participants was estimated by the number of veneers that did not require a clinical intervention, and the survival rate by all veneers that did not fail absolutely. The risk difference (RD) with 95% confidence intervals (CIs) for dichotomous outcomes was used to quantify the intervention effect. Of 973 screened articles, 6 clinical studies were included. The survival and success rates varied depending on the bonding substrate. Enamel-bonded veneers had almost perfect rates of survival (99% with a range of 98% to 100%) and success (99% with a range of 98% to 100%). Veneers bonded to composite resin or surfaces with minimal dentin exposure had slightly lower survival rates (94% with a range of 91% to 97% and 95% with a range of 91% to 100%, respectively) and success rates (70% with a range of 60% to 80% and 95% with a range of 90% to 99%). Severe dentin exposure significantly decreased both survival rates (91% with a range of 84% to 98%) and success rates (74% with a range of 64% to 85%). The combined findings suggested that ceramic veneers bonded to enamel had fewer clinical complications (RD: −0.04; 95% CI: −0.09 to 0.02) and lower failure rates (RD: −0.13; 95% CI: −0.32 to 0.07) compared with those bonded to exposed dentin. Additionally, veneers attached to teeth with minimal dentin exposure were significantly less likely to require clinical interventions (RD: −0.16; 95% CI: −0.31 to −0.01) and had a reduced incidence of failure (RD: −0.08; 95% CI: −0.17 to 0.01) compared with those with severe dentin exposure. Ceramic veneers bonded to enamel showed higher survival and success rates with lower clinical incidences of complications and failure than those bonded to dentin or teeth with existing composite resin restorations.","PeriodicalId":501672,"journal":{"name":"The Journal of Prosthetic Dentistry","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140629249","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}

However, any correlation between prosthetic palatal obturation and middle ear function is unclear. The purpose of this clinical trial was to assess whether prosthetic palatal obturation with a feeding appliance prevented or improved middle ear problems in infants with a cleft lip and palate. Ten infants with congenital cleft lip and palate (20 ears) were referred to the Prosthodontics department immediately after birth. Assessment of the middle ear function by tympanometry as well as hearing quality by auditory brainstem response (ABR) was conducted before the prosthetic treatment (control readings). The middle ear function and hearing quality was followed up after the prosthetic treatment every month until surgical palatal closure (tenth month). The Friedman test was applied to compare data from the various study periods. When the results were significant, the Dunn post hoc test was conducted to compare the control first week readings with those of the later periods (α=.05 for all tests). The preprosthetic readings of tympanometry in the first week were 90% Type A and 10% Type B for both right and left ears. Readings starting from the first to the fifth month revealed no statistically significant differences compared with the first week readings (>.05). However, tympanometry readings starting from the sixth month (20% Type A and 80% Type B) until the tenth month (90% Type B and 10% Type C) for both ears represented a statistically significant difference compared with the first week readings (≤.05). The preprosthetic readings of ABR in the first week showed that 90% of ears had normal hearing status and 10% had mild hearing loss. Readings starting from the first until the fifth month revealed no statistically significant differences compared with the first week readings (>.05). However, ABR readings starting from the sixth month (20% normal hearing, 70% mild hearing loss, and 10% moderate hearing loss) until the tenth month (0% normal hearing, 80% mild hearing loss, and 20% moderate hearing loss) for both ears revealed a statistically significant difference compared with the first week readings (≤.05). Prosthetic palatal obturation with a feeding appliance plays a role in delaying rather than preventing the occurrence of otitis media with effusion in infants with a cleft lip and palate and could reduce the need for ventilation tubes.","PeriodicalId":501672,"journal":{"name":"The Journal of Prosthetic Dentistry","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140580461","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}
