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.
Natal and neonatal teeth are an anomaly that involves teeth erupting in a newborn infant's mouth earlier than usual. The incidence ranges from 1:2,000 to 1:3,500 births. Natal teeth are more frequent, approximately three times more common than neonatal teeth. Some authors reported a higher prevalence in females than males.
Teeth can belong to one of two sets of teeth: primary ("baby") teeth or permanent teeth. Often, "deciduous" may be used in place of "primary", and "adult" may be used for "permanent". "Succedaneous" refers to those teeth of the permanent dentition that replace primary teeth (incisors, canines, and premolars of the permanent dentition).
Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. As such, they are considered part of the human digestive system. [1] Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food ...
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 lymphatic vessels . The plexus of Raschkow is a network of nerves immediately beneath the odontoblast layer of the dentine, first described by J. Raschkow in 1835.
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.
The mouth is the body orifice through which many animals ingest food and vocalize.The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet.
Relative incidence of odontogenic cysts. [1] Dentigerous cyst is labeled at top right. A dentigerous cyst, also known as a follicular cyst, is an epithelial-lined developmental cyst formed by accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth.
