Most 80-year-olds regain chewing ability with dentures, though some with natural teeth or no dentures show high bite force and masticatory performance. This study highlights the impact of dental health on elderly function.

Area of Science:

  • Gerontology
  • Dental Public Health
  • Biomedical Engineering

Background:

  • Masticatory performance is crucial for elderly nutrition and quality of life.
  • Aging significantly impacts oral health, including tooth loss and reduced bite force.
  • Prosthetic rehabilitation is common among older adults to address these issues.

Purpose of the Study:

  • To assess the masticatory performance in 80-year-old individuals.
  • To identify factors influencing masticatory function in this age group.

Main Methods:

  • A survey involving 283 individuals aged 80 years in Aichi prefecture, Japan.
  • Dental examinations included assessing remaining teeth, occlusion, and prostheses use.
  • Measurements of bite force and a masticatory performance questionnaire were administered.

Main Results:

  • A significant portion of participants were edentulous (44.5%) or had no occlusion (77.4%).
  • 90.8% of individuals used prostheses, indicating widespread rehabilitation.
  • Higher bite force and masticatory ability scores were observed in those with 20+ teeth or not using prostheses.

Conclusions:

  • Dental prostheses effectively restore masticatory ability in most 80-year-olds.
  • A subset of individuals with natural teeth or without dentures demonstrated superior bite force and chewing function.
