Study Notes
Prevalence of Edentulism
- 60% of men and 70% of women aged over 65 are edentulous, indicating a significant prevalence of tooth loss in older populations.
Changes in Tooth Appearance with Age
- Aging causes changes in tooth color, with chroma and hue variations as enamel thins and dentin becomes exposed.
- Dentin exposure makes teeth more susceptible to extrinsic staining.
- Medications containing heavy metals can deepen the chroma of teeth over time.
Aging Dention Characteristics
- Natural teeth may appear jagged and brownish due to the breaking of incisal edges and accumulation of extrinsic stains on exposed dentin.
Aesthetic Preferences in Prosthodontics
- Some patients may prioritize aesthetic preferences over the dentist's recommendations, opting for complete dentures featuring smaller, straighter, and whiter teeth rather than replicas of natural teeth.
Impact of Edentulism on Nutrition
- The loss of teeth can lead to a diminished sense of taste, which is often associated with malnutrition in older adults.
Edentulism in Older Adults
- 60% of men and 70% of women over the age of 65 are edentulous.
- High prevalence of tooth loss in elderly populations indicates a significant health issue.
Changes in Tooth Appearance
- Aging affects tooth color; chroma and hue change as enamel wears down.
- Dentin becomes more visible due to enamel abrasion, leading to deeper chroma from heavy metal medications.
- Natural teeth develop a jagged brownish appearance from aging and extrinsic staining.
Patient Preferences in Dentures
- Some patients prefer complete dentures with teeth that are smaller, straighter, and whiter than natural teeth, conflicting with dentists' aesthetic standards.
- Preference for artificial aesthetics may differ from natural appearance.
Nutritional Impact and Chewing Efficiency
- Tooth loss can lead to a diminished taste sense, contributing to malnutrition in elderly patients.
- Masticatory efficiency in complete denture wearers is about 80% lower than in individuals with natural dentition, impacting overall health and nutrition.
