To explain dentists' variation in endodontic retreatment decision making a praxis concept (PC) has been generated. PC assumes that practitioners operate along a health continuum. Various periapical conditions are then perceived as different stages on a continuous health scale, based on their radiographic appearance. PC suggests that an individual's placement of a cut‐off point for retreatment on the health continuum to a large extent is dependent on the agent's personal values. In the present study value judgements (utilities) concerning two periapical health states in endodontically treated teeth were investigated among 82 dental students. The two methods used to elicit utilities, a Visual Analogue Scale (VAS) and the Standard Gamble (SG), produced large inter‐ and intra‐individual variations. VAS frequently generated lower utility values. The results obtained in the study satisfy a necessary criterion for the validity of PC and strengthen the position of the theory.
