Dental Terminology Flashcards
Brachycephalic:
Shortening of the facial bones. In these breeds, mandibles are
often shortened, often with ventral bowing. Because of space constraints, teeth
are often rotated or impacted/retained (unerupted)
mesocephalic:
this is the skull shape of the classic dog (wolf) or wild cats
Dolichocephalic:
this describes elongation of the facial bones and are typically
seen in sight hounds and oriental cats. In these animals display increased
interdental space at especially the premolar teeth.
Coronal:
positioned towards the tooth crown.
Apical:
position towards the root apex (tip).
Proximal:
tooth surfaces adjacent to neighbouring teeth in the same arcade.
Interproximal:
the space between adjacent teeth in the same arcade.
Rostral:
used to describe areas of the face or jaw towards the tip of the nose.
Caudal:
used to describe areas of that face and jaw towards the tail
Mesial:
the area of the tooth facing the midline between the central incisors. (In
most teeth the “rostral” aspect)
Distal:
the aspect of the tooth opposite to mesial (in most teeth the caudal
aspect)
Palatal:
the aspect of maxillary the tooth facing the palate.
Lingual:
the aspect of the mandibular teeth facing the tongue.
Vestibular: (also the facial aspect)
the aspect of the tooth opposite to either
lingual or palatal. This aspect faces the oral vestibule and this could also be
described as a labial in premolar, incisor and canine teeth or buccal in
caudal-most premolar and molar teeth.
Labial:
The aspect of the teeth facing the lips.
Buccal:
the aspect of the tooth that faces the cheek.
Line angle:
these lines demarcate the meeting of different aspects of the tooth
(“corners”of teeth). E.g. the mesiobuccal line angle is located where the mesial
and buccal aspects of the tooth meets.
Occlusal surface:
the surface of the tooth that occludes with teeth in the opposing
jaw.
The incisive edge:
the cutting surface of incisor teeth and in cats and dogs also
of those of premolars and molar teeth.
Cingulum:
the ridge in dentin and enamel onto which opposing incisor teeth rest.
In dogs and cats this describes the ridge on the palatal aspect of the maxillary
Incisors onto which the incisive edge of the mandibular incisors rests in normal
occlusion.
Cusp:
A well demarcated conical protrusion of the crown. These start as
independent centres during the embryonal development of the tooth crown.
Cervical:
the so-called neck of the tooth or junction between the root and crown.
Diastema.
the edentulous areas of gingiva between adjacent teeth.
Gingival sulcus:
the potential space between the crown and the free gingiva.
Periodontal pocket:
the consequence of destruction of the normal sulcus by
periodontitis and therefore deeper and normal sulcular depth.
Carnassial:
this indicates the main cutting or shearing teeth in carnivore dentition.
The maxillary carnassial is always the fourth maxillary premolar and the
mandibular carnassial, always the mandibular first molar.
