The perceived benefit of endodontic retreatment
Results.



The individual mean RPS range was 0.27–0.63. Elicited utilities for health state A and B ranged from 0.65 to 0.99 and 0–0.99. On five occasions negative utilities for health state B were obtained. Calculated RTB ranged from 0 to 0.99. Mean values, standard deviations (SD), medians and ranges are displayed in Table 1.
No statistically significant correlation between RPS and RTB was detected at the first ( P = 0.92; r s = 0.03) or second judgement ( P = 0.08; r s = −0.45).
Intrarater reliability over time is displayed graphically in Fig. 4 and the means, standard deviations (SD) and 95% limits of agreement are presented in Table 2.
No statistically significant systematic change between assessments was detected for RPS ( P = 0.43), health state A ( P = 0.45), health state B ( P = 0.66) or RTB ( P = 0.61).
