The periodontium (from Greek περί (peri-) 'around' and -odont 'tooth') is the specialized tissues that both surround and support the teeth, maintaining them in the maxillary and mandibular bones. Periodontics is the dental specialty that relates specifically to the care and maintenance of these tissues. It provides the support necessary to ...
The osseous tissue replaces the periodontal ligament which causes the tooth to be fixed and cannot undergo eruptive change. Ankylosis usually occurs in primary molars; however, it can also take place in other primary teeth , as well as secondary dentition .
Dental impressions are negative imprints of teeth and oral soft tissues from which a positive representation can be cast. They are used in prosthodontics (to make dentures), orthodontics, restorative dentistry, dental implantology and oral and maxillofacial surgery. [3]: 136–137
A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
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 dental pulp is the central part of the tooth filled with soft connective tissue. [16] This tissue contains blood vessels and nerves that enter the tooth from a hole at the apex of the root. [23] Along the border between the dentin and the pulp are odontoblasts, which initiate the formation of dentin. [16]
In fact, you don’t even need to make a trip to a dentist’s office. At-home teeth whitening is a booming market, and there are plenty of products to help switch up your smile. Plus, not only ...
In dental anatomy, the gingival fibers are the connective tissue fibers that inhabit the gingival tissue (gums) adjacent to teeth and help hold the tissue firmly against the teeth. [1] They are primarily composed of type I collagen , although type III fibers are also involved.
