A comparison of two questionnaires measuring oral health‐related quality of life before and after dental hygiene treatment in patients with periodontal disease

Abstract

No statistically significant difference could be found after DHtx compared to before in regard to OHRQoL assessed with OHIP-14 and GOHAI. However, there was a greater variety in the responses with the GOHAI questionnaire; it may hereby be more useful for patients with periodontal disease.
