Oral Status and Care Needs of People Aged 90 and Over

Study Overview
=================
Brief Summary
-----------------
This study will help describe the state of oral health of very old people (over 90).

Detailed Description
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| State of the mouth and teeth | Number of decayed, absent and closed teeth | Inclusion visit | 
| Masticatory ability | Number of functional units | Inclusion visit | 
| Root caries index | 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. | Inclusion visit | 
| Hygiene index | Hygiene index (OHI-S, Simplified Oral Hygiene Index ; from 0 to 3) | Inclusion visit | 
| Oral pain | Presence of oral pain yes/no | Inclusion visit | 
| Oral lesions | Presence and nature of oral lesions according to the International Classification of Diseases applied to odontology and stomatology of the World Health Organization | Inclusion visit | 
| Hyposalivation / xerostomia | Presence of hyposalivation / xerostomia (Xerostomia Inventory, XI, 11 items questionary) | Inclusion visit |
