Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums.
The gums are part of the soft tissue lining of the mouth. They surround the teeth and provide a seal around them. Unlike the soft tissue linings of the lips and cheeks, most of the gums are tightly bound to the underlying bone which helps resist the friction of food passing over them. Thus when healthy, it presents an effective barrier to the ...
A tooth (pl.: teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food.Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young.
Gingival fibers. 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. These fibers, unlike the fibers of the periodontal ...
Gingival and periodontal pocket. In dental anatomy, the gingival and periodontal pockets (also informally referred to as gum pockets[1]) are dental terms indicating the presence of an abnormal depth of the gingival sulcus near the point at which the gingival (gum) tissue contacts the tooth.
Junctional epithelium. In dentistry, the junctional epithelium (JE) is that epithelium which lies at, and in health also defines, the base of the gingival sulcus (i.e. where the gums attach to a tooth). The probing depth of the gingival sulcus is measured by a calibrated periodontal probe. In a healthy-case scenario, the probe is gently ...
1611. FMA. 56665. Anatomical terminology. [edit on Wikidata] The periodontal ligament, commonly abbreviated as the PDL, are a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which they sit. [1] It inserts into root cementum on one side and onto alveolar bone on the other.
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.
