  abstract  = {Background: Target values for cardiovascular risk factors in patients with coronary heart disease (CHD) are stated in guidelines for the prevention of cardiovascular disease. We studied secular trends in risk factors over a 12-year period among CHD patients in the region of Munster, Germany. Methods: The cross-sectional EUROASPIRE I, II and III surveys were performed in multiple centers across Europe. For all three, the Munster region was the participating German region. In the three periods 1995/96, 1999/2000, and 2006/07, the surveys included (respectively) 392, 402 and 457 <= 70-year-old patients with CHD in Munster who had sustained a coronary event at least 6 months earlier. Results: The prevalence of smoking remained unchanged, with 16.8\% in EUROASPIRE I and II and 18.4\% in EUROASPIRE III (p=0.898). On the other hand, high blood pressure and high cholesterol both became less common across the three EUROASPIRE studies (60.7\% to 69.4\% to 55.3\%, and 94.3\% to 83.4\% to 48.1\%, respectively; p<0.001 for both). Obesity became more common (23.0\% to 30.6\% to 43.1\%, p<0.001), as did treatment with antihypertensive and lipid-lowering drugs (80.4\% to 88.6\% to 94.3\%, and 35.0\% to 67.4\% to 87.0\%, respectively; p<0.001 for both). Conclusion: The observed trends in cardiovascular risk factors under-score the vital need for better preventive strategies in patients with CHD.},

  abstract  = {Introduction For both students and teachers, it is challenging to learn and teach a correct crown preparation. The purpose of this study was the design, feasibility and evaluation of a 3D printed tooth model with internal preparation for dental education in crown preparation and to analyse the quality of the prepared printed teeth in comparison with prepared standard model teeth. Materials and methods A printable tooth was designed and printed by a stereolithographic printer. 38 fourth-year dental students in the first clinical course in prosthodontics were trained in a voluntary course using printed teeth. Different aspects of the printed tooth were evaluated by a questionnaire using German school grades (1 best to 5 worst). The quality of the preparation with the printed teeth and standard training teeth was also rated in an evaluation form done by an expert group consisting of five experienced dentists. Results The workflow was feasible and cost-effective for the production of the teeth. The overall rating of the printed tooth was {\O} 2.0 ± 0.34 in the questionnaire completed by the students. The students rated the printed tooth model ({\O} 2.1 ± 0.85) as significantly better than the standard model tooth ({\O} 3.3 ± 0.77; P = .000). The students reported great benefits in the use of this model tooth, for example valuable replacement of a standard model and real teeth, direct control of material loss. The quality of the preparation was evaluated by the expert group as significantly better with an overall mean grade of {\O} 2.6 ± 0.37 for the printed teeth compared to {\O} 2.9 ± 0.42 for the standard model teeth (P = .000). Conclusions The feasibility of this teaching concept was confirmed. The students favoured to work on the innovative 3D-teeth with internal preparation, emphasising the usefulness of this technique in dental education. The expert group confirmed also the significant training effect of this tooth model in contrast to a standard model tooth.},

  abstract  = {Introduction The preparation for dentin posts is difficult and hard to learn. There are currently no reproducible simulation models to train this clinical procedure. The purpose of this study was the design, feasibility and evaluation of a three-dimensional (3D) printed tooth model for the pre-clinical teaching of students. Materials and methods A printable tooth was designed and printed by a stereolithographic printer. A total of 48 fourth-year dental students in the first clinical course in prosthodontics were trained in a voluntary hands-on course on 4 similar printed teeth. The students used standard model teeth and real-teeth models during their education. They had experience in caries removement and root canal treatment on real patients. Root perforations were counted for every attempt. The different benefits of the 3D printed tooth were evaluated by a questionnaire using German school grades from 1 (best) to 6 (worst). Results The overall rating of the printed tooth was {\O}1.9 ± 0.3. The item "suitable exercise option" was rated {\O}2.0 ± 0.8, and the teeth were "easy to use" {\O}1.9 ± 0.9. The item "realistic approach to dentin post preparation" was rated {\O}2.1 ± 0.8, and the teeth showed the "shortcomings at a root perforation" {\O}1.5 ± 0.6. The students reported to have much more motivation and enthusiasm to improve their skills with the printed teeth {\O}2.1 ± 0.9. They had a strong desire to include these teeth in their pre-clinical education before the first patient treatment {\O}1.6 ± 0.8. The success rate of the dentin post preparation was significantly better for the second 25\% (P = .047) and fourth 48\% (P = .04) attempt. Conclusions The feasibility of this teaching concept was confirmed. The students had the possibility to learn a correct dentin post preparation on a printed tooth model. The learning effect with this tooth model was rated as good to very good by the questionnaire.},
