Impact of dental conditions on patients' quality of life

Quality of life measures have rarely been used in dentistry to assess oral health status. The purpose of this paper is to assess the utility of using standard indicators to measure the impacts of dental conditions on patients' quality of life. Quality of life was conceptualized as a multidimensional construct including three major aspects: social functioning, measured by the Sickness Impact Profile; well-being, measured by the Gill Well-Being Scale, Spielberger State/Trait Anxiety Scale, and the Corah Dental Anxiety Scale; and symptoms, measured by the Kiyak Oral Functioning Scale, the McGill Pain Questionnaire, and the West Haven Multidimensional Pain Inventory. 152 patients were recruited from private dental practices consisting of 48 TMJ, 33 periodontal, 23 denture, and 48 recall patients. Patients in the first three groups reported numerous impacts on quality of life and the impacts were particularly severe for the TMJ patients. The indicators used were sensitive to differences among the four groups and hold promise for further development of quality of life indicators for use in epidemiologic surveys and clinical dental trials.
