Jaw dysfunction symptoms were uncommon in long-term care residents, with no clear links found between clinical signs and patient complaints or denture quality. This oral health study highlights prevalent issues but low reported dysfunction.

Area of Science:

  • Geriatric Dentistry
  • Oral Health Research
  • Mandibular Function

Background:

  • Oral health is critical for residents in long-term care institutions.
  • Jaw dysfunction can impact quality of life and nutritional intake.
  • Previous research has not fully elucidated the prevalence and correlates of jaw dysfunction in this demographic.

Purpose of the Study:

  • To investigate the prevalence of jaw dysfunction signs and symptoms in long-term care residents.
  • To explore associations between clinical signs of mandibular dysfunction, subjective complaints, occlusal status, and denture quality.

Main Methods:

  • A cross-sectional study involving 653 residents from 40 long-term care facilities in Vancouver.
  • Data collection included personal interviews and comprehensive dental examinations.

  • Analysis focused on jaw function, occlusal stability, denture status, and reported symptoms.

    • Main Results:

    • 13% reported jaw dysfunction symptoms (e.g., sore muscles); 20% exhibited clinical signs.
    • 43% had unstable occlusal contacts; 37% used loose or unstable dentures.
    • No significant association was found between clinical signs and subjective complaints or oral appliance quality.

    Conclusions:

    • Complaints and clinical signs of jaw dysfunction, excluding joint noises, were infrequent in this long-term care population.
    • Mandibular dysfunction appears uncommon, suggesting other oral health issues may be more prevalent.
    • Further research is needed to understand the specific factors contributing to jaw dysfunction in elderly institutionalized individuals.
