    Stein, Linda Maria; Bergdahl, Maud; Pettersen, Kjell Sverre; Bergdahl, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-01)
    Numerous conceptual models of health literacy have been proposed in the literature, but very few have been empirically validated in clinical contexts. The aim of this study was to test the effects of the conceptual model of health literacy as a risk in a clinical dental context. A convenience sample of 133 Norwegian-speaking adults was recruited. Participants were randomly allocated to an intervention ...
  • 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)

  • Five-minute Apgar score ≤ 5 and molar incisor hypomineralisation (MIH) - a case control study 

    Sidaly, Rivan; Schmalfuss, Andreas Jørn; Skaare, Anne B; Sehic, Amer; Stiris, Tom; Espelid, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-22)
    Background: The aetiology of molar incisor hypomineralisation (MIH) is unclear. The asymmetric distribution of MIH in the dentition may indicate that an insult of short duration that affects ameloblasts at a vulnerable stage could be a causative factor. Apgar ≤ 5 at 5 min may indicate asphyxia (hypoxic-ischemic insult) during birth. It was hypnotised that low Apgar score during birth may cause MIH. ...
  • Longitudinal Evidence for Smaller Hippocampus Volume as a Vulnerability Factor for Perceived Stress 

    Lindgren, Lenita; Bergdahl, Jan; Nyberg, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
    Hippocampal volume has been found to be smaller in individuals with stress-related disorders, but it remains unclear whether smaller volume is a consequence of stress or rather a vulnerability factor. Here, we examined this issue by relating stress levels to hippocampal volumes in healthy participants examined every 5 years in a longitudinal population-based study. Based on scores of 25- to ...
