Some rests become calcified in the periodontal ligament (cementicles). ERM plays a role in cementum repair and regeneration. [ 1 ] The stem cells in ERM can undergo an epithelial – mesenchymal transition and differentiate into diverse types of cells of mesodermal and ectodermal origin like bone, fat, cartilage and neuron-like cells.
The formative role of the dental follicle starts when the crown of the tooth is fully developed and just before tooth eruption into the oral cavity. [2]Although tooth eruption mechanisms have yet to be understood entirely, generally it can be agreed that many factors, together, affect the tooth eruption process which is why it is very difficult to differentiate the causes and effects.

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 ...
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]
The periodontal ligament depends on stimulation provided by function to preserve its structure. Within physiologic limits the PDL can accommodate increased function by increasing its width. Forces that exceed the adaptive capacity of the periodontium produce injury called trauma from occlusion. When occlusal forces are reduced the PDL atrophies ...
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 ...
Oral and maxillofacial pathology refers to the diseases of the mouth ("oral cavity" or "stoma"), jaws ("maxillae" or "gnath") and related structures such as salivary glands, temporomandibular joints, facial muscles and perioral skin (the skin around the mouth). [1] [2] The mouth is an important organ with many different functions. It is also ...
The tissues which have been derived from each of the three components are: The dental follicle → will develop to become the periodontal ligament, the cementum and the alveolar bone; The dental papilla → will develop to become the dental pulp and the dentine; The enamel organ → will develop to create the enamel solely
