The term anterior teeth refers to incisors and canines, as opposed to premolars and molars, which are posterior teeth. [1] Apical The direction toward the root tip(s) or apex(es) of a tooth (the apices), as opposed to coronal, which refers to the direction toward the crown.
The taper of each preparation on the abutment teeth must be the same. This is known as parallelism among the abutments and allows the bridge to fit onto the abutment teeth. Adhesive bridges require minimal preparation. Master impressions: An accurate impression should be made of the prepared teeth, along with an impression of the opposing arch ...
Tooth mobility is the horizontal or vertical displacement of a tooth beyond its normal physiological boundaries [1] around the gingival (gum) area, i.e. the medical term for a loose tooth. Tooth loss implies in loss of several orofacial structures, such as bone tissues, nerves, receptors and muscles and consequently, most orofacial functions ...
Special terms are used to describe the mouth and teeth. [2] Fields such as osteology, palaeontology and dentistry apply special terms of location to describe the mouth and teeth. This is because although teeth may be aligned with their main axes within the jaw, some different relationships require special terminology as well; for example, teeth ...
A root canal is the naturally occurring anatomic space within the root of a tooth. It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
The impact from the primary tooth will be transferred to the permanent tooth that may have its roots formed, thus causing a bend or curvature of the permanent tooth root. [5] It is noted that rather than the force of the impact, the direction in which the impact occurs has a more significant effect on dilaceration formation.
Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root of a tooth. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.
Dental alveoli (singular alveolus) are sockets in the jaws in which the roots of teeth are held in the alveolar process with the periodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called a gomphosis (plural gomphoses). Alveolar bone is the bone that surrounds ...
