Analytical results of prospective clinical study on Hobo occlusion score; our challenges for the future

Abstract

The aim of this prospective clinical study was to evaluate the changes in oral health-related quality of life (OHRQOL) due to dental treatment for patients, and to evaluate the influence of the type of interventions. 127 patients who underwent dental treatment were selected. Chronological QOL change during dental treatment was measured. The subjects completed the Hobo occlusion score (HOS) and shortened Japanese version of the Oral Health Impact Profile (OHIP-J14) before and after dental treatment. Complete data of the 127 subjects were analyzed with the Wilcoxon signed-rank test. The results showed that total HOS and OHIP-J14 score were significantly reduced after dental treatment. The results showed that the HOS is clinically sensible, reliable, valid and responsive for patients who need dental care.
