목적: 치과 치료에 사용되는 일부 비위험 기구들에 대한 치과의사의 감염 관리 인지도와 감염 관리 실태를 조사하고자 하였다. 연구 재료 및 방법: 대전광역시, 충청남도, 충청북도 및 전라북도 지역의 40개 치과 병, 의원을 연구 대상으로 하였다. 감염 관리에 대한 치과의사의 인지도와 실천정도에 관해서 설문 조사를 시행하였고, 연구 대상인 치과의사가 치과 치료에 사용하는 인상용 건, 광중합기, 3-way syringe, 색조 견본, 치실통의 표면 오염도를 아데노신 3인산 측정기를 이용하여 측정하였고, 감염 관리에 대한 인식도와 실태 간의 상관관계를 분석하였다. 결과: 감염 관리에 관한 인지도와 시행 빈도는 3-way syringe에서 가장 높았다. 모든 기구에서 소독액을 사용한 표면 소독이 가장 많이 시행되었다. 표면 오염도는 3-way syringe, 색조 견본이 인상용 건, 광중합기, 치실통보다 낮게 나타났다. 결론: 치과 치료에 사용되는 비위험 기구들 중에서 3-way syringe는 사용자의 감염 관리 인지도와 표면 오염도 간에 유의한 상관관계가 있으며, 감염 관리의 인지도가 높을수록 표면 오염도가 낮은 것으로 나타났다.
Abstract
Purpose: The aims of this study were to evaluate the dentist’s awareness and the actual status of infection control of noncritical dental instruments. Materials and Methods: 40 dental clinics in Daejeon, South Chungcheong, North Chungcheong and North Jeolla provinces were surveyed. The questionnaire was delivered to the dentists belonging to those clinics, and the awareness and the practice of infection control were examined. The microbial contamination on the surface of five noncritical instruments (impression gun, light curing unit, 3-way syringe, shade guide, and dental floss dispenser) used by them was measured with an ATP luminometer. Correlation analysis between the awareness and the actual state of infection control was conducted. Results: Awareness and frequency of infection control was highest in the 3-way syringe. Surface disinfection using disinfectant was most frequent in all instruments. 3-way syringes and shade guides were less contaminated than impression guns, light curing units, and dental floss dispensers. Conclusion: 3-way syringes had a significant correlation between user awareness of infection control and surface contamination, and the higher awareness, the lower the contamination measurement was shown.
