Questions
Answer
The tooth at the centre of
a fully developed adult jaw is the
First molar
In a permanent maxillary
first molar the buccal developmental groove is parallel to the
Distobuccal root
The root tips of the
permanent maxillary first molar often curve towards the
Centre axis
The cusp arm of the
mesiopalatal cusp of a typical permanent maxillary first molar is
Obtuse angled. It is the
most obtuse angled cusp. Hence it is the bluntest cusp of the entire cusps.
The distobuccal and
mesiolingual cusp form has
Right angled
The usually missing cusp in
a permanent maxillary second molar, if missing is the
Distopalatal cusp
The shortest teeth
occlusocervically in the mandible is the
Second molar
In the permanent dentition
the buccal ridges and height of contour forms a “tilited E shaped” pattern in
Mandibular first molar. The
lingual ridges and the height of contour forms the “U shaped” pattern.
The lingual developmental
groove of the permanent mandibular first molar is aligned with the
Furcation
In a maxillary molar the
most indistinct and rounded line angle is the
Distobuccal
