Dentine

Dentine is somewhat elastic, yellowish, and mineralized avascular tissue supports the enamel and encloses the pulp chamber.

Composition of dentine-

60% Inorganic appetite

40% Fibrillar protein collagen

or

70% apatite

20% collagen 

10% of water

The formation of dentine is known as dentinogenesis.

Odontoblasts cells produce dentine.

The function of dentine is to support and protect the enamel from enamel fracture and masticatory forces. It also protects the pulp from other harmful microbial and other harmful stimuli.

Types of dentine-

1. Predentine.

2. Secondary dentine.

3. Tertiary dentine.

It is harder than bone and softer than enamel consists of apatite crystals. If dentine gets exposed it can cause sensitivity due to cold, heat, acidic or sticky substance reaches inside the tooth causing pain.

Sensitivity can cause Sceviour pain and other disease, heart problems. This problem of sensitivity can be healed by brushing with fluoride-containing toothpaste twice a day.

    Interesting post and I am guessing that this is why many of us experience toothache.

  Tour to Uttrakhand with my camera The moment I reached to Uttrakhand I made a new friend and that was my camera who stayed every time with me to shoot everything. Nature was wonderful, peaceful, with unique terrain mountains covered with ice, shining like gold in the rising sun and hilly areas with floating rivers, spiritual mystery, stunning landscape, etc. I saw different kinds of people, humanity, they all were so helping nature everything was so good. The Guesthouse was so relaxing, warm as their nature was so cold, they gave me hot water for needs, warm clothes, and a tourist guide. and all this has been shot in my camera for future diaries. I also have seen so many people suffering from many diseases, health problems resulted in bad teeth like- Cardiovascular disease, Dementia, Respiratory infections, Diabetes, Pregnancy complications, infertility, the degenerative loss of teeth, calcification, deposition of calculus these were the common problems which I saw there. I hope I wo

 Let's learn some more about Cells of Pulp As I already discussed pulp in my previous blog Today I will tell you about Cells present in the pulp tissue in detail. CELLS- Odontoblasts These are the second most prominent cells in the pulp and lies in the periphery of the pulp adjacent to the predentine also called the " odontogenic zone of the pulp".  The shape of odontoblast in the tooth pulp - Tall and columnar in the crown portion.  Cuboidal in the middle of the root. Flat and Spindle shape in the apex of the root. Odontoblast is approx 5-7 microns in diameter. Fibroblasts These are the cells that occur in the greatest amount in the pulp tissue. The function of these cells is to form college fiber and ground substance and maintain them throughout the life of the pulp.  But it also has the ability to ingestion and degradation of collagen fiber and ground substance. The Shape of the cells- Stellate shaped cells having extensive processes that communicate with the processes
