[Cross-cultural adaptation of quality of life indices for oral health].

The aim of this study was to evaluate the cross-cultural adaptation of the main quality of life instruments related to oral health. Studies on cross-cultural adaptation of oral health-related quality of life measures were searched for in LILACS and MEDLINE. Twenty-nine articles were analyzed, identifying distinct methods for cross-cultural adaptation of oral health-related quality of life measures. Such differences could jeopardize the future use of these instruments, since the instruments may not adequately represent the health status of the respective target populations.
