Abstract

Oral diseases stemming from oral pathogenic bacteria pose a significant global health concern, and current methods for managing these pathogens have limitations. Plasma‐activated water (PAW), containing various reactive species, emerges as a promising disinfectant with impressive inactivation capabilities. In this study, PAW prepared by mixed‐mode plasma‐activated gases was applied to inactivate oral pathogenic bacteria, including Streptococcus mutans and Porphyromonas gingivalis. The PAW could reduce more than 6.1‐log10 planktonic bacteria and 4.1‐log10 bacteria within biofilm, respectively, and PAW treatment of planktonic bacteria effectively inhibited biofilm formation. Compared to chlorhexidine, PAW exhibited superior inactivation effects in both planktonic bacteria and biofilm. This study presented a potent strategy for bacteria eradication to reduce the incidence of oral diseases.

等离子活化水对口腔病原体变异链球菌和牙龈卟啉单胞菌的高效灭活效果

由口腔致病菌引发的口腔疾病是全球关注的重大健康问题，而目前管理这些病原体的方法存在局限性。等离子活化水（PAW）含有多种活性物质，是一种很有前途的消毒剂，具有令人印象深刻的灭活能力。在这项研究中，采用混合模式等离子体活化气体制备的等离子体活化水被用于灭活口腔致病菌，包括变异链球菌和牙龈卟啉单胞菌。PAW 可分别减少超过 6.1-log10 的浮游细菌和 4.1-log10 的生物膜内细菌，对浮游细菌的 PAW 处理可有效抑制生物膜的形成。与洗必泰相比，PAW 对浮游细菌和生物膜都有更好的灭活效果。这项研究为减少口腔疾病的发生提供了一种有效的灭菌策略。
