Hypercementosis
“What is hypercementosis? A detailed question and answers guide”
Question 1. Hypercementosis
Answer:
- It is a prominent thickening of cementum
- It may be diffuse or circumscribed
- It may affect all teeth or single tooth
- Observed often in non-functioning teeth
- It is characterized by a reduction in the number of Sharpey’s fibers embedded in the root
- It is found in teeth exposed to greater stress
- This increases the surface area for the firmer anchorage of the tooth
- An excessive deposition is circumscribed and surrounds the root like a cuff

Question 2. Cementocytes
Answer:
- Some cementoblasts become entrapped within their own matrix they are called cementocytes
- They are oval spider-like structures
- They have very little cytoplasm and numerous processes called canaliculi
- Those processes may branch and anastomose with those of neighboring cells
- Most of the processes are directed towards the PDL surface of the cementum which is the site of diffusion for essential nutrients since the cementum is avascular

- They are present in spaces called lacunae
- Cementocytes in the deeper layers are nonviable
- They have reduced secretory activity
- They become progressively further from the nutritive source
- They show few organelles with dilated endoplasmic reticulum
- They are in stages of degeneration
