Age-induced changes in the teeth and their attachment apparatus.

Area of Science:

• Dental Science
• Gerodontology
• Biomaterials Science

Background:

• Tooth and supporting tissues undergo continuous physiological and pathological changes throughout life.
• Age-induced alterations in hard and soft dental tissues are significant and impact tissue function.
• Differentiating between physiological and pathological changes can be challenging.

Purpose of the Study:

• To review the age-related structural and biological changes in dental hard and soft tissues.
• To highlight the functional implications of these age-related changes.
• To emphasize the importance of considering these changes in therapeutic approaches.

Main Methods:

• Literature review of age-related changes in dental tissues.
• Analysis of structural modifications in enamel, dentine, cementum, and pulp.
• Examination of changes in tooth supporting tissues and their physiological movements.

Main Results:

• Dentine exhibits narrowing tubules, increased calcification, and reduced fluid, enhancing its wear resistance.
• Cementum shows continuous, functionally induced deposition with age.
• Pulp volume decreases due to secondary dentine deposition; cellular properties change without significant vitality loss.
• Circulation is affected by hard tissue deposition, necessitating age-specific endodontic treatments.
• Tooth supporting tissues undergo constant rearrangements.

Conclusions:

• Age-related changes in dental tissues fundamentally alter their biological properties and functions.
• These structural and biological differences necessitate tailored therapeutic strategies.
• Current therapeutic approaches may not sufficiently account for these age-related variations.
