Movement of teeth is determined by two factors: deposition of bone on the tension side and resorption of the bone on the compression side of the periodontal ligament (PDL). During this movement, bone remodelling is initiated by the PDL in which forces are transmitted from the tooth to the alveolar bone. Fibroblasts of the PDL will react to ...
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 ...
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 ...
Sands recommends using a tissue or dry cloth to pat the surface of the teeth as “moisture can hinder the adhesion of the strips and effectiveness of the whitening gel.” Gently fit and press ...
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.
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.

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 ...
The increased permeability of the JE that allows emigration of the PMN type of WBC also allows microorganisms from the dental biofilm (especially noted is P. gingivalis, and associated toxins from the exposed tooth surface) to enter this tissue from the deeper lamina propria, setting up the possibility of infection to occur.
