The HADS is a 14-item self-assessment scale designed to evaluate emotional stress induced by chronic pain in non-psychiatric populations. HAD-A assessed anxiety and HAD-D evaluated depression. Scores of greater than 10 were indicative of anxiety or depression, scores of 7 or less were indicative of no significant anxiety and depression, and scores of 8 to 10 indicated borderline anxiety or depression.

The General oral health assessment index (GOHAI) is a questionnaire about the impact of oral health on quality of life. It includes 12 items evaluating three dimensions of oral health with respect to quality of life: (1) functional field (eating, speaking, and swallowing); (2) psychological field (appearance, social relationship); (3) pain or discomfort concerning gums or teeth. Each item has a score ranging from 1 to 5. The GOHAI-add score corresponds to the sum of the scores and ranges from 12 to 60 (20 for functional field, 25 for psychological field, and 15 for comfort/pain field). A score higher than 57 is high and indicates a satisfactory oral quality of life. A score from 51 to 56 is average and a score of 50 or less is low, reflecting a poor oral quality of life.
