Abstract

Purpose: The purpose of this study was to evaluate the cleansing effect of recently developed alkaline ionized water, e-WASH, on microorganisms of the denture surface. Materials and methods: Removable partial and complete dentures were randomly assigned to the experimental group of 41 dentures, and the control group of 26. The denture was immersed in the e-WASH solution (experimental group), or tap water (control group) for 5 minutes. The plaque was collected from the denture surface before and after immersion, and smeared on the slide glass. Amount and motility of microorganisms were compared according to the morphology and strain of microorganisms, using the phase contrast microscope. Statistical analysis was accomplished with paired t-test and independent t-test at 95% confidence level (P<.05). Results: 1. The amount of cocci, bacilli, filamentous, spiral/comma, and the motility of bacilli, filamentous, and spiral/comma were decreased after denture cleansing with the alkaline ionized water, e-WASH (P<.05). But in the control group, only the amount of cocci showed a significant difference (P<.05), but no difference from the others. There were no differences in other analysis. 2. In the experimental group, the amount of cocci, bacilli, filamentous, spiral/comma, and the motility of bacilli, filamentous, and spiral/comma were smaller and more inactive compared to the control group (P<.05). Conclusion: These results indicated that the alkaline ionized water, e-WASH could effectively reduce the amount and motility of the experimented microorganisms on the denture surface, and that e-WASH could be recommended as an effective denture cleanser.

연구 목적: 본 연구는 최근 개발된 알칼리 이온수 e-WASH의 의치에 부착된 미생물 의치세정 효과에 대해 위상차현미경을 이용한 미생물 관찰법을 통하여 알아보고자 하였다. 연구 재료 및 방법: 실험군 41개, 대조군 26개의 의치를 무작위로 선정하여 실험군에서는 알칼리 이온수e-WASH로, 대조군에서는 수돗물에 5분간 침지 전, 후 의치 내면의 치면세균막을 채취하였다. 위상차현미경으로 구강미생물의 형태적, 종류별 양과 운동성에 대하여 세정 전, 후별 구강미생물의 상태를 관찰하였다. 결과: 1. 알칼리 이온수 e-WASH로 의치를 세정한 실험군에서는 세정 전보다 세정 후 구균의 양, 간균의 양, 간균의 운동성, 실사균의 양, 실사균의 운동성, 콤마/나선균의 양, 콤마/나선균의 운동성 등 모든 조사항목에서 감소하였다 (P<.05). 한편 대조군에서는 구균의 양은 감소하였으나 (P<.05), 다른 조사항목에서는 모두 세정 전, 후 간에 차이가 없었다. 2. 알칼리 이온수e-WASH로 의치를 세정한 실험군에서는 구균의 양, 간균의 양, 간균의 운동성, 실사균의 양, 실사균의 운동성, 콤마/나선균의 양, 콤마/나선균의 운동성 등 모든 조사항목에서 수돗물로 의치를 세정한 대조군보다 각 구강미생물의 양과 운동성이 적게 나타났다 (P<.05). 결론: 위의 결과를 통해 알칼리 이온수 e-WASH가 의치표면의 각종 미생물의 양과 운동성을 효과적으로 감소시키므로 의치세정제로 추천된다.
