          Abstract

          Objectives: The aim of this project was to develop an instructional video that demonstrates a standardized clinical examination on patients with suspected temporomandibular disorders (TMD). After viewing the video, the learner should be knowledgeable about the examination steps and application of the examination techniques.

          Methods: The instructional video was created by two dentists who are experienced in assessing patients with suspected TMD. Additionally, both examiners were calibrated according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). The instructional video was divided into chapters. Various camera angles, key points, image enlargements, and replays were used to better depict essential aspects of the assessment. Background noise was reduced to a minimum.

          Results: The instructional video was modified and completed in two phases: the first by an experienced dentist and the second by a dentist specialized in TMD. The final video includes nine chapters and is 26.5 minutes in length ( https://doi.org/10.5061/dryad.k8r7qc1).

          Conclusion: Divided into chapters, this German instructional video shows an optimally timed, standardized clinical assessment of patients with suspected TMD.

          Zusammenfassung

          Zielsetzung: Ziel dieser Arbeit war die Erstellung eines Instruktionsvideos, welches das Erlernen der Methodik zur Untersuchung von Patienten mit Verdacht auf craniomandibuläre Dysfunktionen (CMD) unterstützen soll. Nach Betrachten des Videos sollte der Lernende den Ablauf einer Untersuchung und die Anwendung der Untersuchungstechniken kennen.

          Methodik: Ein Instruktionsvideo wurde von zwei Zahnärzten, welche in der Befunderhebung von Patienten mit Verdacht auf CMD erfahren sind, angefertigt. Zusätzlich waren beide Untersucher gemäß der Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) kalibriert. Das Instruktionsvideo wurde in Kapiteln angelegt. Für eine verbesserte Darstellung wesentlicher Aspekte der Befunderhebung wurden verschiedene Kameraperspektiven, Stichpunkte, Bildvergrößerungen und Wiederholungen der Inhalte verwendet. Hintergrundgeräusche wurden auf ein Minimum reduziert.

          Ergebnisse: Mittels zweier Evaluationsphasen, wobei die erste durch erfahrene und die zweite durch auf CMD-spezialisierte Zahnärzte erfolgte, wurde das Instruktionsvideo sukzessive modifiziert und fertiggestellt. Das finale Video umfasst neun Kapitel und hat eine Gesamtdauer von 26,5 Minuten ( https://doi.org/10.5061/dryad.k8r7qc1).

          Schlussfolgerung: Das deutsche Instruktionsvideo stellt den zeitlich optimierten Ablauf einer standardisierten Befunderhebung in Kapiteln dar, welche bei Patienten mit Verdacht auf craniomandibuläre Dysfunktion angewendet werden kann.

          Research diagnostic criteria for temporomandibular disorders: a systematic review of axis I epidemiologic findings.

          The aim of this study was to summarize and systematically review the literature on the prevalence of different research diagnostic criteria for temporomandibular disorders (RDC/TMD) version 1.0 axis I diagnoses in patient and in the general populations. For each of the relevant papers, the following data/information were recorded for meta-analysis and discussion: sample size and demographic features (mean age, female-to-male ratio); prevalence of the assigned diagnoses; prevalence of the diagnoses assigned to the left and right joints, if available; prevalence of the diagnoses assigned to the 2 genders, if available; prevalence of the different combinations of multiple diagnoses, if available; and prevalence of TMD (only for community studies). Twenty-one (n = 21) papers were included in the review (15 dealing with TMD patient populations and 6 with community samples). The studies on TMD patients accounted for a total of 3,463 subjects (mean age 30.2-39.4 years, female-to-male ratio 3.3), with overall prevalences of 45.3% for group I muscle disorder diagnoses, 41.1% for group II disc displacements, and 30.1% for group III joint disorders. Studies on general populations accounted for a total of 2,491 subjects, with an overall 9.7% prevalence for group I, 11.4% for group IIa, and 2.6% for group IIIa diagnoses. Prevalence reports were highly variable across studies. Myofascial pain with or without mouth opening limitation was the commonest diagnosis in TMD patient populations, and disc displacement with reduction was the commonest diagnosis in community samples.

            Effective Educational Videos: Principles and Guidelines for Maximizing Student Learning from Video Content

            Educational videos provide an important content-delivery tool in many classes. Effective use of video is enhanced when instructors consider cognitive load, student engagement, and active learning. This essay reviews literature relevant to these elements and suggests practical ways instructors can use these principles when using video as an educational tool.
