Tooth numbering system without letters
FDI Numbering System.
Visible structure on tooth with extensive gingival recession
anatomical & Clinical crown
which state describes the periodontum
The oral hard and soft tissues that support the teeth.
Most visible structure in the oral cavity
Clinical crown.
Proximal caries usually occur on smooth surface area
below(gingival to) the contact area
Term for continuous space produced by curvatures of teeth that provides a
passage for food to escape
Embrasure.
Embrasure located below the contact area
Gingival embrasure.
Proximal contacts of posterior teeth viewed occlusally
More buccal in a buccal to lingual direction
,Contact area of anterior teeth viewed from incisal
More center in a buccal to lingual direction.
Thickest enamel location
At the incisal and occlusal areas.
Dental pulp functions
Provides nutrients and fluids to the dentin through the blood supply.
Exception regarding dental pulp
Dental pulp increases in size with age.
Dental tissue with tubules containing protoplasmic extensions
Dentin.
Composition of enamel
95.5% inorganic material, 0.5% organic material and 4% water.
Composition of dentin
70% inorganic material, 20% organic material and 10% water.
Tooth tissue providing developmental and sensory functions
Dental pulp.
Pulp Functions
Pulp provides the developmental, sensory, nutritive and sensory functions for the
tooth.
Dental Tissue with Tubules
Dentin is comprised of tubules that contain protoplasmic extensions of the cells
that line the pulp chamber.
Where does the Dentin tissue located
Dentin lies just inside enamel and cementum.
Tooth Tissue Resembling Bone
, Cementum most resembles bone.
Pulp resembles which tissue
Normal dental pulp most resembles gelatinous tissue
Visible Part of Tooth
The term used to describe the visible part of the tooth in the mouth is clinical
crown.
Pulp Damage Causes
Pulp can be harmed by the caries process and by sterilizing, cleaning, drying and
desensitizing agents.
Oblique Ridge Location
The oblique ridge is located on maxillary molars between the ML and DB cusps.
Incisor with Acute Angle
The incisor with the most acute mesioincisal angle is the Maxillary central.
Concavity on Anterior Teeth
The concavity located on the lingual surface incisal to the cingulum on anterior
teeth is known as a lingual fossa.
Canine Distal Surface
Both maxillary and mandibular canines are more rounded on the distal surface.
Difference Between Canines and Incisors
A basic difference between canines and incisors is the cusp tip that is unique to
canines.
Width of Incisors
The mandibular central incisor is about half the width of the mandibular lateral
incisor.
Linear Elevation of Tooth Surface
Any linear elevation of the surface of a tooth is described as a ridge.
