| Summary: | <p>Introduction: The aim of this study is to evaluate, within the scope of an experimental design, to</p><p>what extent the assessment of two different settings of prepared cavities, based on video sequences,</p><p>containing digital analysis tools of the prepCheck software, as well as to what extent they deviate from</p><p>one another and are reliable.</p><p>Materials and Methods: For this prospective, single-centred, experimental study, 60 examination</p><p>cavities related to a ceramic inlay preparation were assessed by four trainers in two different settings (A:</p><p>video fi lm versus B: video fi lm plus an analogue model assessment) by using a standard checklist. The</p><p>examined parameters contained: the 1. preparation / outer edges, 2. surface & smoothness / inner edges,</p><p>3. width & depth, 4. slide-in direction, 5. outer contact positioning and 6. overall grade on a Likert scale of 1</p><p>= 'excellent', 2 = 'very good', 3 = 'good', 4 = 'satisfactory' to 5 = 'unsatisfactory'. An evaluation questionnaire</p><p>with 33 items was additionally addressed to the concept of application of a digital-analytic software.</p><p>The statistical analysis, using SAS 9.2 (SAS Institute Inc., Cary, USA, PROC MIXED) and R (Version 2.15,</p><p>Package lme4) concerned the reliability, inter-rater correlation and signifi cant factors at a p of 0.05.</p><p>Results: The assessment of the individual criteria and overall grade of the control group (A) were,</p><p>on average, lower (i.e. better) than in the study group (B), yet with the exception of the 'outer contact</p><p>positioning', without conclusive statistical signifi cance. The reliability lay at an average of α=0.83 (A) and</p><p>α=0.79 (B). The maximum reliability of the criteria 'preparation edge', 'surface', 'width & depth' as well as</p><p>'overall grade' were reasonable in the assessment mode, with α > 0.7. The inter Video-based Assessment 3</p><p>rater correlation was at an average of 0.43 < r < 0.74 higher in assessment mode A than B that comprised</p><p>0.35 < r < 0.60.</p><p>Conclusion: The current examination shows an average reliability in the assessment mode A that</p><p>exceeds the requirements for practical examination (α ≥ 0.6) and also fulfi ls the general requirements for</p><p>'high-stake' examinations of α ≥ 0.8.</p> |
