Odontogenic infections can be severe if not treated and are associated with mortality rate of 10 to 40%. [4] Furthermore, about 70% of odontogenic infections occur as periapical inflammation, i.e. acute periapical periodontitis or a periapical abscess. [3] The next most common form of odontogenic infection is the periodontal abscess. [3]
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.
The periodontal membranes of all human teeth, as well as those of monkeys, rats, guinea pigs, and mice, contain oxytalan fibers. [ 5 ] [ 6 ] It is also mentioned that a portion of oxytalan fibers support the lymphatic and blood vessels that lead to the teeth .In periodontal membranes of teeth under higher stress, as those used as bridge ...
Histologically, an excess amount of keratin is noted on the surface of the tissue, and the tissue has all the layers of an orthokeratinized tissue with its granular and keratin layers. In patients who have habits such as clenching or grinding their teeth, a larger area of the buccal mucosa than just the linea alba becomes hyperkeratinized. This ...
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.
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.
Periodontics is the dental specialty that relates specifically to the care and maintenance of these tissues. It provides the support necessary to maintain teeth in function. It consists of four principal components, namely: [1] Gingiva (the gums) Periodontal ligament (PDL) Cementum; Alveolar bone proper
Calcifying odontogenic cyst (COC) is a rare developmental lesion that comes from odontogenic epithelium. [2] It is also known as a calcifying cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass.
