Including the patient's oral health perspective in evidence-based decision-making.

BACKGROUND: How to approach the assessment of patient-perceived oral health is of fundamental importance for the evaluation of clinical and public health interventions because the patient's assessment should be used as an adjunct to objective dental findings in order to decide which interventions work. AIM: This review article aims to provide an overview of the principles, current status, and future outlook for how a patient's oral health perception can and should be assessed. REVIEW FINDINGS: The hierarchical position of dental patient-reported outcomes, oral health-related quality of life (OHRQoL), and dental patient-reported outcome measures within the hierarchical concepts of quality of life and its component, health-related quality of life, is presented. The Mapping Oral Disease Impact with a Common Metric project is outlined as an international effort to describe current approaches to standardize the measurement of oral impact using the four OHRQoL dimensions of oral function, orofacial pain, orofacial appearance, and psychosocial impact. CONCLUSION: Ultimately, these four dimensions of OHRQoL provide a practical and psychometrically solid way to collect and analyze OHRQoL data for all oral diseases in all settings, and eventually for all treatments through the use of a standardized, universal measurement tool. This universal impact metric capturing the patient's oral health perspective is the key to moving evidence-based dentistry and value-based oral health care forward.
