The questionnaire is classified into seven subscales, with two questions in each subscale. Questions are answered according to the patients’ experience within the past 1 month, using scores of 0 to 4: very often = 4, fairly often = 3, occasionally = 2, hardly ever = 1, and never = 0. The oral health impact profile score (0–56) is the value obtained by summing the score for each question item.
