alignment

alignment  

The location of the tooth relative to the supporting alveolar bone and adjacent and opposing teeth.
alveolar crest

alveolar crest  

The most coronal part of the alveolar bone. In the healthy periodontium, the distance between the alveolar crest and the cement–enamel junction is 1–2mm, as measured on a radiograph.
analgesia

analgesia  

(an-ăl-jeez-iă)reduced sensibility to pain, without loss of consciousness and without the sense of touch necessarily being affected.
blood

blood  

(blud)a fluid that circulates throughout the body, via the arteries and veins, providing a vehicle by which an immense variety of different substances are transported between the various organs and ...
bone sounding

bone sounding  

The process of probing anaesthetized tissue with a periodontal probe to establish the level of the underlying alveolar bone.
caries

caries  

n. decay and crumbling of the substance of a tooth (see dental caries) or a bone. —carious adj.
cementum

cementum  

(si-men-tŭm)a thin layer of hard tissue on the surface of the root of a tooth. It anchors the fibres of the periodontal membrane to the tooth.
cyst

cyst  

1. A fluid-filled sac bounded by a multicellular wall that may result from a wide range of insults (e.g. hydatid disease, sebaceous cyst) or be of embryological origin.2. A resting stage of many ...
dentine

dentine  

(den-teen)a hard tissue that forms the bulk of a tooth. The dentine of the crown is covered by enamel and that of the root by cementum.
drainage

drainage  

The emptying of fluid from a cavity or lesion by means of an external pathway. For example the drainage of pus from a periapical abscess through the alveolar bone to the surface mucosa.
drill

drill  

(dril)(in dentistry) a rotary instrument used to remove tooth substance, particularly in the treatment of caries. It consists of a dental handpiece that takes variously shaped burs.
dysostosis

dysostosis  

n. the abnormal formation of bone or the formation of bone in abnormal places, such as a replacement of cartilage by bone.
elevator

elevator  

(el-i-vay-ter)1 an instrument that is used to raise a depressed broken bone. periosteal e. an instrument used in orthopaedics to strip the fibrous tissue (periosteum) covering bone.2 a lever-like ...
enamel matrix derivative proteins

enamel matrix derivative proteins  

(EMD)Proteinaceous materials associated with the development of acellular cementum, periodontal ligament, and alveolar bone.
endosteum

endosteum  

A membrane consisting of a thin layer of connective tissue that lines the marrow cavity of bone. It takes an active part in the repair of fractures.
enostosis

enostosis  

A localized mass of proliferating bone tissue within a bone. Radiographically it has a cotton wool appearance and can be distinguished from sclerosing osteitis in that it is separated from the tooth ...
fibroma

fibroma  

A non-malignant (benign) neoplasm of connective tissue: they are rare in the oral cavity and most nodules of fibrous tissue are reactive hyperplasia to trauma and not neoplasms. An ameloblastic ...
genioplasty

genioplasty  

A surgical procedure designed to reshape the contour of the chin, usually by reduction or extension by augmentation with grafted bone, cartilage, or artificial material.
Howship's lacuna

Howship's lacuna  

[J. Howship (1781–1841), English surgeon] n. small pit or groove in bone that is being resorbed by osteoclasts.
infrabony defect

infrabony defect  

A periodontal pocket with its base apical to the crest of the alveolar bone. Infrabony defects may have one, two, or three bone walls.
