Abstract –  Although the concept of positive health has been around for more than 60 years, acceptable measures of this construct have yet to emerge. Potential explanations are that there is no consensus on how it is to be defined and its ambiguous status with respect to medical and socioenvironmental models of health. In this paper we review definitions of positive health, the origins of these definitions, the way the concept of positive outcomes has been used in research on the outcomes of oral and orofacial conditions and assess whether the concept of positive health has any merit in terms of applied oral health research. This literature reveals many competing and imprecise definitions, many of which are similar to other constructs, such as well-being. Most are lacking empirical referents or indicators. In examining the literature on oral health we found five distinct, although overlapping, ways in which the concept of positive health has been framed: (i) positive health as the absence of negative health states; (ii) positive health as positively worded items; (iii) the positive outcomes of oral health; (iv) positive oral health as a set of psychological and social attributes, and (v) the positive outcomes of chronic conditions such as oro- and craniofacial differences. Each of these ways can be challenged on conceptual or methodological grounds. For example, the states that comprise the upper end of the negative–positive health continuum have not been defined and health states and determinants of health are often confused. Moreover, the meaning of responses to health status questionnaires and the interpretation of accounts of the illness experience is often unclear. Nevertheless, the notion of positive health, irrespective of its merits and public policy implications, provides a context for methodological and theoretical debate that can only serve to enrich theory and practice with respect to measures of health and quality of life and therapeutic interventions at the individual and population.
