MAXILLARY FIRST PREMOLAR Shape:
From the buccal aspect, the crown is
roughly:
- TRAPEZOIDAL
The distal root depression of MAXILLARY
SECOND PREMOLAR is deeper than the
mesial depression on the maxillary second
premolar. This characteristics of the distal
root surface is the opposite of that of the
maxillary first premolar, in which the
depression is on the mesial surface of the
root.
The mesial slope of the buccal cusp ridge is
usually SHORTER than the distal slope.
The opposite is true of the first premolar.
A characteristic of the LINGUAL
SURFACE of the mandibular first premolar
is the mesiolingual and developmental
groove. This groove acts as a line of
demarcation between the mesiobuccal lobe
and the lingual lobe and extends into the
mesial fossa of the occlusal surface.
The usual outline form of the mandibular
first premolar from the occlusal aspect is
roughly DIAMOND SHAPED and similar to
the incisal aspect of mandibular canines.
The three-cusp type appears square
lingual to the buccal cusp ridges when
highly developed . The round, or two-cusp
type appears round lingual to the buccal
cusp ridges.
The square type has three cusps that
are distinct ; the buccal cusp is the
largest , the mesiolingual cusp is next ,
and the distolingual is the smallest.
In zoology, the premolars are those
teeth that succeed the deciduous molars
regardless of the number to be
succeeded.
The maxillary premolars are
developed from four (4) lobes, same
as the anterior teeth.
