Anatomy of the
Teeth
Tissues of the Tooth
Enamel – the hard tissue that covers the
crown portion of the tooth (hardest
substance in the body).
 Cementum – the substance covering the
root surface of the tooth.
 Dentin – the material forming the main
inner portion of the tooth structure.
пЃ®
пЃ®
Pulp – the vital tissues of the tooth
consisting of nerves, blood vessels, and
connective tissue.
chamber – open area in center of tooth,
found in the crown area; place for the pulpal
tissues.
 Pulp canal – small canal or trench area in the
center of the root, containing the pulpal
vessels.
п‚Ё Pulp
Parts of a Tooth
пЃ®
Crown – top portion of the tooth covered
by enamel.
п‚Ё Clinical
crown - portion of the tooth that is
visible in the mouth.
 Anatomical crown – the total portion of the
crown that is covered by the emanel.
пЃ®
Root – bottom part of the tooth; may be
single-, double-, or triple-root.
root – portion of the root covered by
the gingival (gum) tissue.
 Anatomical root – total portion of the root
covered by the cementum.
п‚Ё Clinical
Cervix – neck – the neck of the tooth at
the cementoenamel junction.
 Apex – the anatomic area at the end of the
tooth root.
пЃ®
Tissues surrounding the Teeth
Alveolar process – the extension of the
maxilla and mandible that surrounds and
supports the teeth to form the dental
arches.
 Alveolar bone – the part of the alveolar
process that lines the bony sockets into
which the roots of the teeth are
embedded.
пЃ®
пЃ®
Periodontal ligament – dense connective
tissue organized into fiber groups that
connects the cementum covering of the
root of the tooth with the alveolar bone of
the socket wall.
пЃ®
Gingiva – the mucous membrane tissue
that immediately surrounds the tooth.
gingiva – the portion of the gingiva
extending from the gingival margin to the
alveolar mucosa.
 Free gingiva – the part of the gingiva that
surrounds the tooth and is not directly
attached to the tooth surface.
п‚Ё Attached
Important Oral Cavity Structures
пЃ®
Labia – lips
oris – upper lip
 Inferior oris – lower lip
 Commissure – area at the corners of the mouth
where the lips meet.
 Vermillion – area where the pink-red lip tissue meets
the facial skin.
 Philtrum – the median groove on the external surface
of the upper lip.
п‚Ё Superior
пЃ®
Frenum – a tissue fold attachment that connects
two parts.
frenum – tissue that attaches the inside of lip to
the mucous membrane in the anterior of the oral
cavity.
 Lingual fremun – attaches the lower side of the
tongue to the floor membrane.
 Buccal frenum – attaches the side of the cheeck to
the oral cavity in the maxillary first molar area.
п‚Ё Labial
пЃ®
Palate – roof of the mouth
palate – composed of palatine
processes of the maxillae bones.
п‚Ё Hard
пЃ®
Rugae – irregular folds or bumps on the anterior
surface of the hard palate.
palate – flexible portion located in the
posterior region of the oral cavity.
п‚Ё Soft
пЃ®
Gag reflex – protective mechanism located in the
posterior region of the soft palate.
пЃ®
пЃ®
пЃ®
Uvula – tissue structure hanging from from the
soft palate in the posterior of the oral cavity.
Retromolar pad – located at the rear of the
mouth distal to the molars on the mandibular
arch.
Tuberosities – rounded area on the outer
surface of the maxillary bones in the area of the
posterior teeth.
Surfaces of the Teeth
пЃ®
Facial – pertaining to the surface of the
cheek and lips (face).
– pertaining to the lips: anterior surface
of the anterior teeth.
 Buccal – pertaining to the cheek: surface of
the posterior teeth touching the cheek.
п‚Ё Labial
пЃ®
Lingual – surface of the tooth or area
touching the tongue.
Incisal edge – cutting edge of the anterior
teeth.
 Occlusal – chewing surface of the
posterior teeth.
пЃ®
пЃ®
Proximal – side wall of tooth which meet
with or touches the side wall of another
tooth.
– to the middle: side surface closest to
the middle of the face.
 Distal – pertaining to the far or away side:
side farthest from the midline of the face.
п‚Ё Mesial
