The dental follicle, also known as dental sac, is made up of mesenchymal cells and fibres surrounding the enamel organ and dental papilla of a developing tooth. [1] It is a vascular fibrous sac [2] containing the developing tooth and its odontogenic organ. The dental follicle (DF) differentiates into the periodontal ligament.
A condensation of ectomesenchymal cells called the dental sac or follicle surrounds the enamel organ and limits the dental papilla. Eventually, the enamel organ will produce enamel, the dental papilla will produce dentin and pulp, and the dental sac will produce all the supporting structures of a tooth, the periodontium. [1]
The nerve fibers will branch out and create a rich plexus around the tooth germ in that structure as the dental follicle is the clear target of these dental nerve fibers. The dental follicle is a fibrous sac that surrounds the odontogenic organ and developing tooth. [11] The plexus is a system of connections of blood vessels, nerves, or ...
Unlike cartilage and bone, as well as cementum, the odontoblast's cell body does not become entrapped in the product; rather, one long, cytoplasmic attached extension remains behind in the formed dentin. [2] The differentiation of the odontoblast is done by signaling molecules and growth factors in the cells of the inner enamel epithelium. [1]

Some of the hormone-related dental problems may begin during perimenopause, when the ovaries gradually make less estrogen. Hot flashes and night sweats are among the most infamous menopause maladies .
The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [27] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [28] The dental follicle gives rise to three important cells: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts ...
Tooth development begins at week 6 in utero, in the oral epithelium. The process is divided into three stages: Initiation; Morphogenesis and; Histogenesis [2]; At the end of week 7 i.u., localised proliferations of cells in the dental laminae form round and oval swellings known as tooth buds, which will eventually develop into mesenchymal cells and surround the enamel organ.
