•US (Dolan & Atchinson, 1993)•1958 60% of 65+ were edentulous•1985 41% of 65+ were edentulous
•Australia (Carter, 1997)•1979 67% of 65+ were edentulous•1996 39% of 65+ were edentulous

Most teeth are lost as people become ‘long in the tooth’ because
of advancing periodontal disease
![Page 4: Orofacial Aging](https://reader035.vdocuments.site/reader035/viewer/2022062218/577ccd531a28ab9e788c009b/html5/thumbnails/4.jpg)
Age alone does not lead to a critical loss of periodontal support.
-Burt, 1994Severe periodontal destrustion occurs in a minority of
the elderly.-Levy, 2002

MYTH / FACT?
Dental caries is not a common disease in older adults, and occurs mainly in the young
![Page 6: Orofacial Aging](https://reader035.vdocuments.site/reader035/viewer/2022062218/577ccd531a28ab9e788c009b/html5/thumbnails/6.jpg)
Dental caries is a chronic progressive disease the causes and
pathogenesis of which are not related to ageing
-Banting, 1991
![Page 7: Orofacial Aging](https://reader035.vdocuments.site/reader035/viewer/2022062218/577ccd531a28ab9e788c009b/html5/thumbnails/7.jpg)
MYTH / FACT?
Salivary flow is decreased in older adults
![Page 8: Orofacial Aging](https://reader035.vdocuments.site/reader035/viewer/2022062218/577ccd531a28ab9e788c009b/html5/thumbnails/8.jpg)
Healthy, non-medicated older adults do not have functionally decreased salivary flow rates or
altered salivary composition due to ageing alone
-Burt, 1994

All oral diseases and conditions are not true ‘ageing’ changes per se,
but may be considered ‘age-related changes’
![Page 10: Orofacial Aging](https://reader035.vdocuments.site/reader035/viewer/2022062218/577ccd531a28ab9e788c009b/html5/thumbnails/10.jpg)
‘age-related changes’
• Accumulation of oral diseases over time• Stress, trauma• Polypharmacy• Psychological, neurogical conditions• Medical conditions

Oral Mucosa
• The clinical appearance of the oral mucosa in many health older persons is indistinguishable from that of younger people.
Salivary disorders
The clinical appearance and histologic character of the oral mucosa
Oral habitsMucosal diseases
Oral mucosal trauma

Oral mucosal immunity is believed to undergo some age-related changes
Age-related structural and immunologic
changes

• Secondary dentin deposition• Pulpal calcification• External root resorption• Increased density and volume of pulpal
collagen fibers• Diminished nerve supply

Coronal and root surface caries
• A greater retention of teeth among elderly persons
• a decline in caries among younger people
![Page 21: Orofacial Aging](https://reader035.vdocuments.site/reader035/viewer/2022062218/577ccd531a28ab9e788c009b/html5/thumbnails/21.jpg)

hygiene

Periodontium
The clinical appearance of periodontal tissue in elderly individual reftects
age-related changes and an accumulation of previous disease
experiences and trauma over time.

Salivary glands
Saliva plays critical role in the maintenance of oral health
Difficulty in chewing
Denture retention
Sensory disurbancesDental caries
Speech dysfunction
Oral mucosal infections
