INTERVAL: Investigation of NICE Technologies for Enabling Risk-Variable-Adjusted-Length dental recalls trial (pilot and follow-on study)
A parallel-group, randomised, controlled comparison of three forms of dental recall strategy (6-month recall, risk-based recall and 24-month recall) evaluated the effectiveness and cost-effectiveness of these dental recall strategies by assessing their impact on maintaining oral health. A cost–benefit analysis was undertaken to assess the efficiency of the alternative recall strategies. Willingness to pay was elicited using a discrete choice experiment.
