1

draw out the lower 6 including the fissure patterns and the cusp shapes

The transverse fissure groove starts on the buccal surface and deepens across the occlusal surface. It ends as a groove on the lingual surface

 

There is also a fissure that runs mesiodistally which starts near the mesial marginal ridge, crosses the central pit and divides into two branches which pass onto either side of the distal cusp

2

describe the features of the buccal aspect 

The buccal surfaces are larger than the lingual surface 

The buccal surface is lingually inclined

Proximal surfaces are convex - distal is rounder because of the distal cusp

The buccal surface has a PIT

3

describe the pulp chamber

usually has 4 pulpal horns

chamber floor is roughly trapezoid or rhomboid 

Most common root configuration includes one mesial root with two canals and one distal root with a single canal

4

where is the mesiobuccal orifice usually found

 under the mesiobuccal cusp

5

where is the mesiolingual orifice commonly found

 slightly lingual to the central groove

6

what does the pulp look like
