This study aimed at comparing scoring results obtained with different scoring approaches and to assess the effect of item cues on each scoring approaches' result.\r\nMaterials and methods: Different scoring approaches (MTF, Count-2, Count-3, \"Vorkauf-Method,\" PS50 , Dichotomized MTF, \"Blasberg-Method,\" Multiple response (MR), Correction for Guessing, \"Ripkey-Method,\" Morgan-Method, Balanced Scoring Method) were retrospectively applied to all MTF items used within electronic examinations of undergraduate dental students at the University Medical Center Göttingen in the winter term 2016/2017 (1297 marking events). Item quality was evaluated regarding formal parameters such as presence of cues and correctness of content. Differences between scoring results of all scoring approaches and the differences between each methods' scoring results of items with and without cues were calculated by Wilcoxon rank sum tests (P < .05).\r\nResults: Average scoring results per item highly differed between the scoring approaches and ranged from 0.46 (MR) to 0.92 (Dichotomized MTF). Presence of cues leads to significantly higher scoring in case of all scoring approaches (P < .001; +0.14 on average). However, effect of cues differed amongst scoring approaches and ranged from +0.04 (Dichotomized MTF) to +0.20 (MR).\r\nConclusion: Scoring of MTF items is complex. The data presented in this manuscript may help educators make informed choices about scoring algorithms."],["dc.identifier.doi","10.1111/eje.12372"],["dc.identifier.pmid","29934980"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65686"],["dc.language.iso","en"],["dc.relation.issn","1396-5883"],["dc.relation.orgunit","Poliklinik für Präventive Zahnmedizin, Parodontologie und Kariologie"],["dc.relation.orgunit","Klinik für Mund-, Kiefer- und Gesichtschirurgie"],["dc.relation.orgunit","Poliklinik für Kieferorthopädie"],["dc.relation.orgunit","Poliklinik für Zahnärztliche Prothetik"],["dc.relation.orgunit","Klinik für Kardiologie und Pneumologie"],["dc.subject.gro","Kprim"],["dc.subject.gro","K’"],["dc.subject.gro","Multiple True-False"],["dc.subject.gro","Type X"],["dc.subject.gro","k of n"],["dc.subject.gro","scoring"],["dc.title","Effect of different scoring approaches upon credit assignment when using Multiple True-False items in dental undergraduate examinations"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Specimens were aged by thermal cycling (10,000 cycles, 5-55°C) and randomly subjected to one of three surface treatments: diamond bur abrasion, aluminum oxide air abrasion, or silica coating. Conventional bonding or a universal adhesive with incorporated silane was applied afterward (each n = 16) and resin composite was attached. In the control groups (each n = 16), resin composite was attached using one of the above adhesives without prior mechanical surface conditioning. After further thermal cycling, the shear bond strength (SBS) and failure modes were assessed. Statistical analyses were performed using ANOVA, Weibull statistics, two sample t-tests, and Chi2-test (P < 0.05). The SBS of the repaired amalgam was significantly lower than that of the composite and mechanical pretreatment significantly increased SBS. The universal adhesive significantly improved the SBS of the repaired amalgam compared to the conventional bonding agent and mechanical pretreatment increased the number of cohesive/mixed failures. Amalgam restorations may be repaired using resin composites, but the resulting SBS is lower than that obtained with composite."],["dc.identifier.doi","10.2334/josnusd.18-0301"],["dc.identifier.pmid","31217385"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16247"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60050"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65687"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.eissn","1880-4926"],["dc.relation.issn","1343-4934"],["dc.relation.orgunit","Poliklinik für Präventive Zahnmedizin, Parodontologie und Kariologie"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","610"],["dc.subject.gro","amalgam"],["dc.subject.gro","composite"],["dc.subject.gro","dental restoration failure"],["dc.subject.gro","dental restoration repair"],["dc.subject.gro","shear bond strength"],["dc.title","Effectiveness of a universal adhesive for repair bonding to composite and amalgam"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
