“…The reduced version of this instrument, the OHIP-14, was developed by Slade in 1997, and validated for use in an elderly population in Australia 5 , and in an adult population in England 6 and Scotland 7 . Furthermore, it was translated and trans-culturally adapted in ten languages 8,9,10,11,12,13,14,15,16,17 , including Portuguese 12 . Its validation however, was tested specially on elderly individuals and urban populations, and its use has not been validated for rural populations speaking Latin languages.…”
