This is the sixth volume of Universitas Odontologica with the current periodicity. Since 2020, the journal is being published by rolling volume and not by issue. Any article received (that meets the initial style and methodology requirements) will be refereed by peers who are external to the institution where the authors are affiliated and, if accepted, the necessary corrections will be completed, submitted to a style review, and published. Volume 43 includes articles in our regular sections.
