    • Perceived Stress and Associated Factors in Russian Medical and Dental Students: A Cross-Sectional Study in North-West Russia 

      Drachev, Sergei Nikolaevich; Stangvaltaite-Mouhat, Lina; Bolstad, Napat Limchaichana; Johnsen, Jan-Are Kolset; Yushmanova, TN; Trovik, Tordis A (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-27)
      The aim was to assess perceived stress (PS) and factors associated with PS in Russian medical and dental students. A total of 406 medical and 283 dental students aged 18–25 years that attended the Northern State Medical University in Arkhangelsk, North-West Russia participated in this cross-sectional study. A structured, self-administered questionnaire was used to collect information on socio-demographic ...
    • Procedure time and filling quality for bulk-fill base and conventional incremental composite techniques—A randomised controlled in vitro trial 

      Leinonen, Kaisa Marika; Leinonen, Jukka; Bolstad, Napat Limchaichana; Tanner, Tarja; Al-Haroni, Mohammed Hasan Hussein; Johnsen, Jan Are Kolset (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-23)
      Objectives: The aims of this randomised controlled laboratory trial were to determine the procedure time and immediate quality (surface porosity and marginal gaps) of fillings placed using the bulk-fill base technique and the conventional incremental technique in simulated clinical settings.<p> <p>Methods: Forty-two dentists and dental students were randomly allocated to use either the bulk-fill ...
