Proof testing to improve the reliability and lifetime of ceramic dental prostheses
No full textOBJECTIVES: Ceramic dental prostheses exhibit increasing failure rates with service time. In particular, veneered crowns and bridges are susceptible to chipping and other fracture modes of failure. The purpose of this manuscript is to introduce a computational methodology and associated software that can predict the time-dependent probability of failure for ceramic prostheses and subsequently design proof test protocols to significantly enhance their reliabilities and lifetimes. METHODS: Transient reliability and corresponding proof testing theories are introduced. These theories are coded in the Ceramic Analysis and Reliability Evaluation of Structures (CARES/Life) code. This software will be used to demonstrate the predictive capability of the theory as well as its use in designing proof test protocols to significantly improve the reliability (survival probability) and lifetime for dental prostheses. A three-unit fixed dental prosthesis (FDP) with zirconia core (ZirCAD) and veneering ceramic (ZirPress) are used to compare the predicted probabilities of failure to general clinical results. In addition, the capability to use proof testing to significantly improve the performance (reliability and lifetime) for this restoration is demonstrated. RESULTS: The probability of failure, P, after five years without proof testing is predicted to be 0.337. This compares to clinical studies showing the failure rate to be between 0.2 and 0.23 after 5 years. After 10 years, reference 18 found the clinical failure rate for similar bridges (but not the same) to be up to 0.28 compared to the predicted P of 0.38. The difference may be due to the analysis applying the load at an inclination of 75° which is more critical than vertical loading. In addition, clinical studies often report a simple survival rate instead of using Kaplan-Meier analysis to properly account for late enrollees. Therefore, true clinical failure rates may be higher than reported and may more closely match the predictions of this manuscript. The effectiveness of proof testing increases with selecting materials less susceptible to slow crack growth (higher SCG exponent, N). For example, proof testing the ZirPress glass-veneered bridges with N = 43.4 analyzed in this manuscript at 400 N bite force for 1 s which induces a failure rate during proof testing of 0.31, reduces the P of bridges not proof tested from 0.45 to an attenuated-proof-tested probability of failure P of 0.21 after 20 years of usage. If another material is selected with improved resistance to SCG of N = 60 and the same loading conditions, the failure rate for the proof tested bridges after 20 years of service drops to 2 in 10,000 from 2.4 in 100 had they been not proof tested. The failure rate during proof testing for this material would be 5.1 in 100. Proof testing a material with absolutely no susceptibility to SCG at the same service load (in this case 285 N, not even the 400 N load used above) results in 0 % failure rate and is of course independent of time. SIGNIFICANCE: The transient reliability and proof test theory presented in this paper and associated computational software CARES/Life were successful in predicting the performance of ceramic dental restorations when compared to clinical data. Well-designed proof test protocols combined with proper material selection can significantly enhance the reliabilities and lifetimes of ceramic prostheses. This proof test capability can be a translational technology if properly applied to dental restorations
Validity and reliability of a questionnaire measuring EBDPs among registered dietitian nutritionist
No full textBACKGROUND: There is a lack of a valid and reliable instrument that measures objective and subjective knowledge of evidence-based dietetic practices (EBDP) among registered dietitian nutritionists (RDNs). The present study aimed to develop and assess the validity and reliability of an EBDP Questionnaire (EBDPQ) with objective knowledge items (i.e., quiz items) among RDNs in the USA. METHODS: Subscales from four existing evidence-based practice (EBP) instruments were combined and modified for dietetics. Content and face validity and internal consistency were used to assess the full survey. Survey responsiveness and test-retest reliability were evaluated within the objective knowledge subscale. Content experts (n = 11) and nutrition professionals (n = 16) completed validation reviews. Doctoral students enrolled in a research course (n = 12) were used to analyse survey responsiveness. Internal and test-retest relability analyses utilised RDN participants (time point 1, n = 482; time point 2, n = 335). RESULTS: Content validation resulted in a 38-item questionnaire. Average percent agreement among face validity reviewers was 95.1%. Only the pre-validation version of the objective knowledge subscale resulted in significantly higher post-course scores (Mdn = 11.50) compared to the pre-course (Mdn = 9.75, p = 0.05). The validated instrument had excellent internal consistency (Cronbach\u27s α = 0.91); however, the objective knowledge subscale was low (Cronbach\u27s α = 0.41). A good degree of reliability was found between the two time points (intraclass correlation coefficient = 0.71). CONCLUSIONS: The EBDPQ demonstrated adequate validity and reliability among RDNs. Future research should assess construct validity, with the responsiveness and objective knowledge subscale requiring additional evaluation through an EBDP course

Interprofessional Collaborative Attitudes: Comparing Social Work Learners to Their Medicine and Nursing Peers
Get PDFInterprofessional learning activities in higher education aim to unite healthcare professionals in their future practice, thus reducing duplication and fragmentation of services. This study uses a social learning perspective to examine advanced practice medicine, nursing, and social work learners’ attitudes toward interprofessional education and collaborative practice activities within their university programs. The authors used a cross-sectional design to administer a questionnaire that included the Interprofessional Attitudes Scale (IPAS) to 151 advanced practice health care learners (internal medicine residents, nurse practitioner students, master’s-level social work students). Findings indicated significant differences in three subsections of the IPAS. Social work learners possessed a more favorable attitude than their medicine and nursing peers on teamwork, roles, responsibilities, and community-centeredness. Social work and nurse practitioner students indicated higher interprofessional bias issues than medical residents. The participants’ age was also found to be significant in the study. Further exploration will afford a more substantial knowledge base to address the fragmented, siloed, and service duplication that works against a more comprehensive and efficient healthcare system
