High-speed hand pieces were the instrument of choice (80.54%) and according to number of spray ports single port was found to be the most common type (80.43%). Alginate was the material of choice as a final impression material (68.24%) followed by condensation-cured silicone (24.32%). Impression trays used by dentists were metal tray 23.53%, rigid plastic tray 12.5% and both 63.97%. Results in concern of the use of the retracting cord indicated that 53.69% never use it. Results also indicated that 36.05% never used temporary crown and bridge. Traditional glass ionomer cements and zinc phosphate cements (56%) were equally selected as best choice for final luting cement of crown and bridge work. Both verbal and written prescriptions (81.73%) were the most common used way of communication between dentists and dental technicians.
