Impact of using denture on cognitive function in the elderly

The Aimof this study is toinvestigate whether using denture can improve cognitive function on the elderly.This study is a clinical trial with 40 subjects, elderly aged =60 years, missing more than 10 teeth with loss of occlusion at the time of the study. Thirty subjects undergone denture treatment and were given dentures.The other subjects were the control group,who underwent pre-prosthetic treatments, but weren't given dentures until after the study has ended.All subjects in the denture group completed a series of cognitive tests using HVLT,MMSE and Verbal Fluency test at baseline and at follow-up sessions 1 and 2 months after using denture. Subjects in the control group completed the cognitive tests at baseline and at follow-up sessions 1 month after pre-prosthetic treatment.Although in the denture group there were improvements in the subjects' cognitive functions between measurements (p < 0.05), the control group also showed the same improvements in the cognitive function when compared to the denture group (p > 0.05). Regardless of whether or not the subjects use denture, the better oral health condition due to pre-prosthetic treatment can give a positive impact for the patients' cognitive function.
