Improving a Centenarian’s Quality of Life
In 2007, a 97-year-old patient presented for treatment at the Geneva Dental School. His dentist had retired. Like many elderly patients, he was left without regular dental care. He lived on a geriatric ward, as he was partly dependent on help with most of the activities of daily living (ADL), such as getting dressed, washing, taking a shower, or climbing stairs. However, he was able to go to the bathroom and get up from bed on his own (ADL score 80, min. 18, max. 126; a low score signifies a high degree of dependency) (Lawton and Brody 1969). He was not bound to a wheelchair, but used a walker. Moreover, he was socially highly active—his family visited on a regular basis and he often went to the restaurant with his friend, who was some 20 years younger. His cognitive function did not seem to be impaired in a normal conversation, although his MMSE score was only 21/30 at that time (Folstein and coworkers 1975). The patient was a retired pharmacist, and his latest passion was astronomy.

* General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.
** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
