About this study

In 2011, according to the French National Institute for Statistics and Economic Research, people aged 85 and over accounted for about 3% of the total population. This proportion will increase sharply due to longer life expectancy on the baby boom generation and is expected to reach 7.5% of the total population in 2050.

This very old population has specific health, related to the presence of co-morbidities and co-medications, but also to a frequent state of dependence.

These general health problems and their treatment can create or accentuate oral problems or complicate their management. Thus, very old people are more likely to have some oral diseases although there is no epidemiological data in France. Conversely, oral problems can have repercussions in terms of quality of life, social relations and nutrition, and are factors of risk or aggravating actual or potential systemic disorders.

This very elderly population is therefore likely to present new challenges of dental care that it is important to document.

Treatment and study plan

Primary outcomes

  1. State of the mouth and teeth

    Time frame: Inclusion visit

    Number of decayed, absent and closed teeth

  2. Masticatory ability

    Time frame: Inclusion visit

    Number of functional units

  3. Root caries index

    Time frame: Inclusion visit

    Root caries index (RCI) - RCI is based on the requirement that gingival recession must occur before root caries surface lesion begin, therefore only teeth with gum recession are examined.

    • 4 surfaces of root are examined (mesial, distal, lingual, and buccal or labial)
    • A judgment of no gum recession is made if CEJ (cement enamel junction) cannot be visualized.

    The root caries index is calculated for an individual using the formula

    • RCI= (R-D) +(R-F) x 100 (R-D) +(R-F) +(R-N) R-N =Recession present surface normal or sound R-D =Recession present with decay root surface R-F= Recession present with a filled root surface.

  4. Hygiene index

    Time frame: Inclusion visit

    Hygiene index (OHI-S, Simplified Oral Hygiene Index ; from 0 to 3)

  5. Oral pain

    Time frame: Inclusion visit

    Presence of oral pain yes/no

  6. Oral lesions

    Time frame: Inclusion visit

    Presence and nature of oral lesions according to the International Classification of Diseases applied to odontology and stomatology of the World Health Organization

  7. Hyposalivation / xerostomia

    Time frame: Inclusion visit

    Presence of hyposalivation / xerostomia (Xerostomia Inventory, XI, 11 items questionary)
