Oral Health and Quality of Life

ADOPTED by FDI General Assembly September, 2015 in Bangkok, Thailand


Oral health is closely related with general health and people’s quality of life (QoL), through affecting their oral functions and social interactions. For example, dental caries may cause impaired chewing, decreased appetite, sleep problems, and poor school and work performance. Traditional methods of measuring oral health and treatment needs are based mainly on clinical indicators. However, these indicators do not necessarily account for the functional and psychosocial aspects of oral health, and coincide with people’s perceptions and concerns about their oral health. Based on the conceptual rationale for subjective measures of a broader view of oral health, a variety of robust measures, such as the ‘oral health-related quality of life’ (OHRQoL), have been developed to measure the extent to which oral conditions affect individual’s behaviour and social functioning, and complement the conventional clinical assessments of oral health.

Studies have shown that the impacts of oral diseases and disorders on OHRQoL are high worldwide. Currently, a number of OHRQoL measures have been validated for a range of populations in different countries, and it is now important to consider their potential applications in clinical practice.


This policy statement covers the effects of oral problems on QoL, its useful measures and their applications in dental practice. It addresses the importance of incorporating OHRQoL measures into assessments of oral healthcare needs and cost-effectiveness, as well as planning oral health services and setting policies.


OHRQoL is defined as ‘a multidimensional construct that reflects (among other things) people's comfort when eating, sleeping and engaging in social interaction; their self esteem; and their satisfaction with respect to their oral health’ (US Department of Health and Human Services).


It is well recognized that oral disease and disorders have negative impacts on people’s oral functions, self esteem, general well-being and social activities. The extent of the impact could be assessed by the OHRQoL measures. These measures can be appropriately incorporated into oral healthcare and global oral health policy. Oral healthcare professionals play an important role in enhancing the quality of life of their patients and the public at large.


FDI recommends and recognizes that:

  • OHRQoL measures combined with clinical and behavioural indicators should be incorporated into assessments of oral healthcare needs of populations, to provide a comprehensive and holistic approach to planning oral health services.
  • All national oral health surveys should include a validated OHRQoL measure, thereby providing a profile of the impacts of oral diseases on people’s daily life.
  • OHRQoL measures are essential outcomes to determine the cost-effectiveness of oral care/treatments and public health interventions.
  • OHRQoL measures are essential in advocacy for oral health policy, and they can be used for setting strategic targets for improvements of global oral health.
  • FDI National Dental Associations play an important role in advocating for all of these recommendations.
