1 PROJECT : Development of an OSCE resources TOOL for Dental Materials in their Clinical Application T. Lodhi

2 STEP I EVALUATION OF STUDENTS’ UNDERSTANDING OF BASIC CONSERVATIVE DENTAL MATERIALS AIM Evaluate the core understanding of common conservative dental materials in their clinical application OBJECTIVE Ascertain whether preference for a material is based on sufficient core knowledge of individual materials to understand clinical implications and application, namely:- Dental Amalgams Resin Composites Glass Ionomers and Resin modified Glass Ionomers Luting cements METHODOLOGY By means of a questionnaire, with questions on : Names of materials, with their trade names Clinical advantages and disadvantages of silver Amalgams Clinical advantages and disadvantages of Resin Composites Differences between GIC and RMGIC and hence clinical handling Names of Luting cements and their specific applications

3 STEP II QUESTIONAIRRE 1. List the names of dental materials, you commonly use in conservative dentistry (List both the name and trade-name) OBJECTIVE: To Test the student’s knowledge of different materials and their trade- names. 2. Do you prefer Resin composites or silver Amalgams, for posterior restorations? 3. List 5 clinical advantages and 5 clinical disadvantages of using silver amalgams 4. List 5 clinical advantages and 5 clinical disadvantages of using Resin composites OBJECTIVE: To Test whether the preference above is related to the student’s clinical knowledge of the Amalgams and Resin Composites. 5. Name a Glass Ionomer material you have used, and for what procedure 6. Name a Resin Modified Glass Ionomer you have used, and for what procedure 7. List the steps in the placement of Vitremer when bonding Amalgam OBJECTIVE: To Test whether the student knows the difference in constituents and therefore clinical handling 8. Name 3 luting cements (with trade names) and what they are specifically used to cement

30 END Of OSCE

31 STEP IV OSCE EVALUATION FORM (for students to complete after the OSCE) Rating each of the statements on a scale from =Strongly agree 2= Agree 3= Not sure 4= Disagree 5= Strongly disagree 1. Structure I understood the questions asked There was enough time to answer the questions. The OSCE covered topics which were covered in the lectures. Your comments on the structure of the module 2. Assessment The questions required me to have more of an understanding of the materials, rather than memorizing facts, to answer the questions This OSCE will help me find my strengths and weaknesses. This OSCE will better prepare me for clinical work on patients, later this year Your comments on assessment of the module 3. Comments What can be done to improve your experience of learning in the module of Dental Materials?
