|January 1, 1986
Summary
Tooth aging affects dental tissues, with predentin and cementum width increasing linearly with age. Secondary dentin formation and calcifications show different age-related patterns in impacted teeth.
Area of Science:
- Dentistry
- Histology
- Gerontology
Background:
- Understanding the effects of aging on dental tissues is crucial for diagnostics and treatment.
- Impacted teeth offer a unique model to study age-related changes without oral cavity environmental influences.
Purpose of the Study:
- To investigate the histological effects of aging on dental tissues.
- To measure changes in secondary dentin, predentin, and cementum width with age.
- To analyze the occurrence of concentric denticles and diffuse calcifications in relation to age.
Main Methods:
- Histological examination of impacted teeth from individuals aged 11 to 76.
- Measurement of secondary dentin, predentin, and cementum width.
- Assessment of concentric denticles and diffuse calcifications.
Main Results:
- Predentin and cementum width demonstrated a linear increase with advancing age.
- Secondary dentin formation and diffuse calcifications exhibited non-linear age-related patterns.
- The incidence of concentric denticles remained consistent across all age groups.
Conclusions:
- Dental tissue aging is characterized by specific changes in dentin and cementum.
- Predentin and cementum exhibit predictable age-related expansion.
- Further research is needed to elucidate the distinct aging patterns of secondary dentin and calcifications.
