Dental science Flashcards
Centric Occlusion
Maximum contact between the occluding surfaces
Contact Area
Area mesial or distal surface of a tooth that touches the adjacent tooth
Concave
Curve inward
Abrasion
Mechanical (wearing away of teeth) by abnormal stressors
Curve of spee
Curvature formed be Maxillary and mandibular arch
Foramen
Short circular opening through bone
Height of contour
Widest point on a specific surface of the crown
Middle third
Division of the root in the middle
Sextant
1/6 th of the dentition tooth
Bifurcated
Divided into 2
Alveolar bone
Bone that forms the sockets for teeth
Alveolar Process
Portion of the Maxillary bone that form the support for teeth of the Max. Arch
Alveolar Crest
Highest point of alveolar ridge
Alveolar Socket
Cavity that’s surrounds the root of a tooth
Apical foramen
Natural opening in the root
Cementum
Specialized connective tissue, that covers root of tooth
Anatomic Crown
Portion of the tooth that is covered with enamel
Condyloid process
The Posterior process of each ramus: articulates with fossa in the temporal bones to form the TMJ ( mandibular condyle)
Dental papilla
Gingiva between the teeth
Exfoliation
Process of shedding primary teeth
Free Gingiva
Gingiva that forms gingival sulcus
Gingiva
Part of the gum tissue that surrounds the teeth and alveolar bone
Gingiva sulcus
Space between the free Gingiva and tooth structure
Histology
The study of the structure and function of body tissue
Humulus
Hook shape process
Lamina dura
Thin, compact bone that lines the alveolar socket
Margins
The edge of a tooth prep where the prep ends and normal tooth anatomy is left
Embrasure
Triangular space in a gingival direction between the proximal surfaces
Dentin
Hard portion of the root that surrounds the pulp and is covered by enamel
Maxillary Tuberosity
Large, rounded area on the outer surface of the maxillary bones in the area or the posterior teeth
Oral
Region of the head pertaining to or located near the mouth
Parotid
Duct associated with the parotid salivary gland , which opens into the oral cavity
Periodontium
Structures that surround, support and are attached to the teeth
Process
A prominence or projection on a bone
Coronal pulp
Part that lies within the crown portion of the tooth
Pulp chamber
The space occupied by pulp
Resorption
The body’s process of eliminating existing bone or hard tissue structure
Temporomandibular joint
Joint on each side of the head that allows movement of the mandible
Zygomatic
Region of the head pertaining to or located near the zygomatic bone
Zygomatic Process
The process of the maxillary bones that extends upward to articulate with the zygomatic bone oral pathology
Canine eminence
External vertical bony ridge on the labial surface of the canines
Acute inflammation
Minimal and short -lasting injury to tissue
Central groove
Most prominent developmental groove on the posterior teeth
Biopsy
Removal of tissue from living patients for diagnostic examination
Cingulum
Raised , rounded area on the cervical third of the lingual surface
Candidiasis
Superficial infection caused by a yeast like fungus
Cusp
Major elevation on the masticating surfaces of canines and posterior teeth
Cellulitis
Inflammation of cellular or connective tissue
Cusp of Carabelli
The fifth supplemental cusp found lingual to the mesic lingual cusp
Chronic inflammation
Continuous injury or irritation to tissue
Congenital disorder
Disorders that are present at birth
Fossa
Wide, shallow depression on the lingual surfaces of anterior teeth
Furcation
Area between 2 or more root branches
Cyst
Closed cell with a definite wall
Ecchymosis
Technical term for bruising
Glossitis
Inflammation of the tongue
Marginal Groove
A developmental groove that crosses a marginal ridge and serves as a spillway
Hematoma
Swelling or mass of blood collected on one area or organ
Marginal ridge
Rounded , raised border on the mesial and distal portions of the lingual surfaces of anterior teeth and the occlusal table of posterior teeth
Inflammation
Protective response of the tissues to irritation or injury
Lesions
Area of pathology
Lichen
Benign , chronic disease that affects the skin and oral mucosa
Lymphoma
Malignant disorder of the lymphoid tissue
Metastasize
To spread (disease) from one part of the body to another
Pathology
Study of disease
Sarcoma
Malignant tumor in connective tissue such as muscle or bone
Tori
Abnormal growths of bone in a specific area
Xerostomia
Dryness of the mouth
