Periodontal health states are difficult to quantify and no formal scale quantifying patients' utilities for periodontal health states exits. Multi‐attribute utility (MAD) techniques were used to develop such a scale. The MAU scale maybe used to quantify patients' assessment of their current periodontal health and that of possible treatment outcomes. Such data, combined with probability values in formal decision analysis techniques would result in improved rationality of treatment planning for periodontal disease. 20 patients attending for routine undergraduate care were interviewed. Data from these interviews were sorted into groups of common interest (domains). Intra‐domain health statements were complied from the interview content. 21 patients ranked the intra‐domain statements on a scale of 0–100. This same group of patients also performed an inter‐domain weighting. Mean results showed that patients were 2× as concerned with how they felt and with the prognosis of possible outcomes, than with how they looked and what facts they knew about their oral health. However, the real value of utilities research lies in application of individual results to treatment planning, as there is a wide range of opinion regarding outcome health states.
