Root resorption is common in older adults, affecting 94% of elderly patients studied. Despite its prevalence, these dental issues in seniors show a high incidence of repair, indicating a positive prognosis.

Area of Science:

  • Dentistry
  • Geriatric Medicine
  • Oral Pathology

Background:

  • Root resorption is a common dental pathology with diverse causes.
  • Increasing life expectancy and improved dental care lead to more elderly individuals retaining teeth longer.
  • Elderly individuals face a higher risk of dental problems, making understanding root alterations crucial for treatment and prognosis.

Purpose of the Study:

  • To investigate the histological and histomorphometric characteristics of root resorption in elderly patients.
  • To assess the prevalence and repair potential of root resorption in geriatric populations.
  • To compare root resorption features between elderly and younger individuals.

Main Methods:

  • Histological and histomorphometric analysis of uniradicular teeth from elderly (65-90 years) and younger (14-20 years) patients.

  • Teeth were fixed, decalcified using EDTA, embedded in paraffin, sectioned, and stained with hematoxylin-eosin.
  • Quantification of resorptive areas and assessment of repair signs were performed.

    • Main Results:

    • Root resorption was observed in 94% of elderly patients' teeth, compared to 30% in younger patients.
    • A significant number of resorptive areas (173 out of 416) in elderly patients showed signs of repair.
    • Resorptions in the elderly were characterized by shallow depth, large surface areas, and a high repair rate.

    Conclusions:

    • Root resorption is a frequent finding in the elderly population.
    • Despite age, elderly patients exhibit a notable capacity for root resorption repair.
    • Understanding these age-related changes is vital for effective dental therapy and prognosis in older adults.
