Study Notes
Function continued
- Cellular cementum has the ability to repair itself in 2 ways:
- Anatomical Repair - Able to repair resorbed or fractured root surfaces to some degree
- Functional repair - Plays a role in periodontal disease healing maintaining the width of the PDL
Clinical Significance
- Cementum over the life course
- Cementogenesis takes place continuously throughout life.
- The thickness, hardness & mineral content increases with age
- The Cemento- Enamel Junction
- The relationship of the CEJ varies among teeth & within the same tooth.
- Overlap = 60-65%
- Gap = 10% → 20% → 30%
Structural abnormalities
- Hypercementosis = excessive deposition of cementum towards apex
- resulting in thicker roots
- The etiology includes:
- Local factors (trauma or inflammation)
- Systemic factors (periodontal disease)
- Idiopathic
- Clinical implications
- It may affect single or multiple teeth.
- Often asymptomatic
- May cause problems for extractions
