The scale has seven sub-dimensions: 'Functional Limitation', 'Physical Pain', 'Psychological Distress', 'Physical Disability', 'Psychological Disability', 'Social Disability', and 'Handicap'. Scores obtainable from the Oral Health Impact Scale range from 0 to 56. Since all questions are in a negative form, a score close to 0 indicates good quality of life related to oral and dental health, while a score close to 56 indicates poor quality of life related to oral and dental health. A high score on the scale indicates low quality of life related to oral health.
