[Economic effects of single-pack dental hygienic materials introduced into daily clinical practice]

To improve and maintain medical safety and quality, it is necessary to construct and manage a safe and economical medical system. Almost five years have passed since single-pack dental hygienic materials were introduced into daily clinical practice in the University Hospital, Faculty of Dentistry, Tokyo Medical and Dental University. The costs of purchasing hygienic materials themselves are higher when using outsourced sterilized single packed ones, compared with when using intra-murally sterilized ones in the past. Proper usage of single-pack hygienic materials sterilized with Ethylene Oxide Gas (EOG) would reduce waste of unused materials and save labor for staff in the Section of Central Supplies. Financially, the use of hygienic materials could be reduced if single-pack dental hygienic materials by outsourcing were introduced into the hospital, because all costs for sterilizing hygienic materials in the hospital could be eliminated.
