Examinations included a knowledge-based objective structured clinical examination (OSCE), a manual skills exercise completed on a typodont (Typ...

The introduction of elastomeric impression materials in dentistry resulted in the development of different methods of tissue retraction in order to achieve accurate impression of the finish line of the tooth preparation, which is necessary to fabricate a prosthetic crown. This area needs to be clean, dry and visible. The gingival retraction method [1] is conducted using a retraction cord soaked...
