The aim of this cost-effectiveness analysis (CEA), performed from a societal perspective, was to compare costs and consequences of an individually tailored oral health educational programme (ITOHEP) based on cognitive behavioural strategies integrated in non-surgical periodontal treatment compared with a standard treatment programme (ST).
Material and Methods
A randomized (n = 113), evaluator-blinded, controlled trial, with two different active treatments, was analysed with respect to their costs and consequences 12 months after non-surgical treatment. Costs referred to both treatment costs and costs contributed by the patient. Consequences (outcome) were expressed as the proportion of individuals classified as having reached the pre-set criteria for treatment success after non-surgical treatment (“successful-NSPT”).
More individuals in the ITOHEP group reached the pre-set criteria for treatment success than individuals in the ST group did. The CEA revealed an incremental cost-effectiveness of SEK1724 [€191.09; SEK9.02 = €1 (January 2007)] per “successful-NSPT” case, of which treatment costs represented SEK1189 (€131.82), using the unit cost for a dental hygienist.
The incremental costs per “successful-NSPT” case can be considered as low and strengthens the suggestion that an ITOHEP integrated into non-surgical periodontal treatment is preferable to a standardized education programme.
