Dental chair unit (DCU) is the most essential equipment for the dental treatment in dentistry. DCU output water is used for various applications during dental treatment. DCU output water must be clean at the same level as drinking water since patients and dental staff are regularly exposed to water ...

치과용 유니트는 무엇인가? | 치과용 유니트(dental chair unit, DCU)는 치과에서 치과치료를 위해 필요한 가장 중요한 장비이다. DCU에는 초음파치석제거기(ultrasonic scaler), 고속 핸드피스(high-speed handpiece), 공기-물사출기(air-water syringe) 등 여러 부속 치과용 기구가 연결되어있다. | |
부속 치과용 기구에서 배출되는 물에 있어서 문제점은? | 환자들은 치과치료 중 부속 치과용 기구에서 배출되는 물에 직접적으로 접촉이 되고, 치과의사, 치과위생사, 치과조무사 등 치과종사자들은 기구에서 발생하는 에어로졸에 항상 노출되어있기 때문에, DCU에서 배출되는 물은 음용수보다 더 높은 수준으로 깨끗해야 한다. 하지만 여러 연구자들의 실험을 통해 DCU에서 배출되는 물이 높은 수준으로 미생물에 오염이 되어있다는 것이 밝혀졌고1-7), 그 중 면역력이 저하된 사람에게 병원성을 보이는 세균들도 검출되었기 때문에, 치과치료 중 사용되는 물로 인해 환자가 세균에 감염될 수 있는 가능성이 제시되어 왔다8-11). 따라서, 미국치과의사협회에서 치과용수 내 세균 수를 밀리리터 당 200 colony forming units (CFU) 이하로 유지할 것을 권고하고 있다12). | |
DCU에 연결되어있는 치과용 기구는? | 치과용 유니트(dental chair unit, DCU)는 치과에서 치과치료를 위해 필요한 가장 중요한 장비이다. DCU에는 초음파치석제거기(ultrasonic scaler), 고속 핸드피스(high-speed handpiece), 공기-물사출기(air-water syringe) 등 여러 부속 치과용 기구가 연결되어있다. 대부분의 치과치료에는 이 부속 치과용 기구에서 배출되는 물을 사용한다. |
