    • Opportunities for caries prevention using an ion-releasing coating material: a randomised clinical study 

      Ørtengren, Ulf Thore; Lehrkinder, Anna; Safarloo, Aram; Axelsson, Jasmine; Lingström, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-04)
      Ion-releasing materials (containing fuoride and boron, for example) have shown caries-preventive efects in vitro. The purpose of the present study was to investigate the impact of multi-ion-releasing coating material on pH stabilisation, plaque accumulation and the bacterial composition of dental plaque during a time period of 90 days. The null hypothesis tested here was that the evaluated material ...

    • Photo-irradiated caffeic acid exhibits antimicrobial activity against Streptococcus mutans biofilms via hydroxyl radical formation 

      Nakamura, Keisuke; Shirato, Midori; Kanno, Taro; Lingström, Peter; Ørtengren, Ulf Thore; Niwano, Yoshimi (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)
      An antimicrobial technique based on photo-oxidation of caffeic acid (CA) has recently been developed, but its effect on biofilm-forming bacteria is unknown. The present study aimed to evaluate the effect of photo-irradiated CA against Streptococcus mutans (cariogenic bacteria) biofilm as it relates to hydroxyl radical formation. S. mutans biofilms grown on hydroxyapatite disks were immersed in CA ...
