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...

Foreign bodies may be embedded in the oral cavity either by traumatic injury or iatrogenically. The commonly encountered iatrogenic foreign bodies are restorative materials like amalgam, obturation materials, broken instruments, needles, and impression materials. This paper describes an asymptomatic presentation of a foreign body in the oral mucosa which clinically appeared like a benign connec...

The purpose of this study was to develop novel experimental (Exp) vinyl polysiloxane (VPS) impression materials (ab initio) and evaluate their reproduction fine details compatibility with pouring materials. Exp were compared three commercial VPSs (Aquasil Ultra Monophase (Aq M), Extrude Medium-Bodied (Extr Elite HD (Elt M)) under dry, moist wet conditions. Five (Exp-I–V) developed, out which Ex...
