Self-assessment of preclinical denture setup using a validated, structured, self-designed questionnaire by undergraduate students

Abstract

Introduction: Our aim was to determine if students who perform well on an initial preclinical examination are more accurate on self-assessments with successive examination. Materials and Methods: This was an observational, descriptive, cross-sectional survey. Ninety-one 2nd year dental students completed two consecutive preclinical examinations on ideal teeth arrangement and two self-assessments. Self-assessment was done using a validated, structured, self-designed questionnaire named “prosthetic denture setup–self assessment questionnaire.” The examinations involved artificial teeth arrangement in Class I jaw relation on maxillary and mandibular ideal edentulous casts mounted on a mean value articulator simulating the clinical procedure of a complete denture patient. Students' and their instructor's assessments were evaluated separately, and statistical results were obtained using t-test and Pearson's product moment correlation coefficient test. Regression analysis was done to predict the student self-assessment and validated self-assessment scores on examination outcomes for both indexed and nonindexed values. Results: The results indicated a significant increase in the examination and student self-assessment mean scores. Regression analysis indicated changes in student self-assessment scores, explained 11.9% of the variation in examination scores. Conclusion: Improvement in student self-assessment also showed improvement in successive examination assessments among dental students completing a preclinical denture setup procedure. The following core competencies are addressed in this article: Medical knowledge, Practice-based learning and improvement, Systems-based practice.

Helping Dentists Make Accurate Denture through PAA Articulator

“…There have been many major modifications and researches in this field of stomato-mechanics in order to facilitate the orientation of the jaws during static and functional movements. The drawbacks of existing methods of measuring wear is that the current mean value articulator is a simplistic design which is utilized by many undergraduates student and postgraduates students for mounting casts followed by various teeth arrangements [3][4][5]. The lack of a few tools may hamper the orientation of the casts before mounting and hold it in position.…”
