Difference Between Dental Papilla And Dental Follicle. Today, we will talk about what is dental papilla, what is dental follicle, and what is the main difference between dental papilla and dental follicle.

What Is The Main Difference Between Dental Papilla And Dental Follicle?

The main difference between dental papilla and dental follicle is that the:

-Dental Papilla is a contraction of ectomesenchymal cells. These cells are known as odontoblasts. Dental papilla can be seen in the histologic sections of a developing tooth.

-Dental Follicle is a dental sac made of mesenchymal cells and fibres. It is surrounded around the dental papilla and enamel organ of a developing tooth.

What Is Dental Papilla?

Dental Papilla is a contraction of ectomesenchymal cells. These cells are known as odontoblasts. Dental papilla can be seen in the histologic sections of a developing tooth. It lies below the cellular enamel organ. It can be seen after 8 to 10 weeks of intra uteral life. After then, it gives rise to the pulp and dentin of the tooth.

Dental papilla and dental follicle form one unit of the tooth known as tooth germ. It is a very important part of the tooth and its supporting structures, as they are formed from these distinct cellular aggregations. Dental papilla has a very rich blood supply and provides nutrition to the enamel organ.

What Is Dental Follicle?

Dental Follicle is a dental sac made of mesenchymal cells and fibres. It is a vascular fibrous sac surrounded around the dental papilla and enamel organ of a developing tooth. It contains the developing tooth and odontogenic organ.

Dental follicle plays an important role in tooth eruption and tooth development. The dental follicle transforms into a periodontal ligament. Also, it can be the precursor of the other cells of periodontium, osteoblasts, cementoblasts and fibroblasts. The dental follicle is developed into the cementum, alveolar bone, Sharpey’s fibres, and periodontal ligament fibres. Like dental papilla, dental follicle also provides nutrition to enamel organ.
