The subjects were requested to complete a questionnaire included health related behaviors and GOHAI. Oral parameters were collected from the treatment records. Follow-up survey using same questionnaire was performed 1 year after baseline survey.
A total of 1,959 subjects completed both survey. Almost half of subjects showed the improvement and 38 % showed lowering of GOHAI score at follow-up. Thirty percent of subjects in active treatment phase gained more than 3 points, while 13 % in maintenance demonstrated lowering more than 3 points.
Oral health-related quality of life measures may be improved during active phase dental treatment. During maintenance phase, patients may have lowering of GOHAI score even they have maintained by periodical supported therapy. Patients' perception of oral health should be investigated more deeply to supply satisfactory dental services. Less
