  • Present in Old age 
  • May result from persistent mild irritation. 
  • Common causes Attrition, Abrasion, Erosion, Caries, Pulp Capping etc.


1) Calcific Degeneration
2) Atrophic Degeneration
3) Fibrosis Degeneration

1) Calcific Degeneration- Part of pulp tissue replaced by calcific material. 

Three types- Diffuse, Dystrophic and Denticles/Pulp stones. 

Diffuse Calcification- Generally observed in Root Canal. Deposits become long, thin and fibrillar on fusing. 

Dystrophic Calcification- Deposition of calcium salts in dead or degenerated tissues. They occur in minute area of young pulp. 

Denticles/Pulp Stones- Usually seen in pulp chamber.

Classification of Pulp Stones


According to Location- Free, Embedded and Attached 

According to Structure- True and False. 

True Pulp Stones- Composed of dentin, Formed from detached odontoblasts or fragment of hertwig's enamel root sheath which stimulates the undifferentiated cells to dentinoblastic activity. 

False Pulp Stones- here degenerated tissue acts as nidus for deposition of concentric layers of calcified tissue.

2) Atropic Degeneration- it is wasting away or decrease in size which occurs slowly as tooth grows old. 

3) Fibrosis degeneration- Here the collagen fibers/unit area increases leading to fibrosis. Number and size of cell decreases. Fibriblastic processes lost. Dentinoblasts decreases in length.
