Purpose: To measure key anatomical landmarks relating to pulp chamber morphology in maxillary furcated bicuspids and to compare it with molars.
N= 107 maxillary bicuspids
•Each bicuspids were radiographed in a buccal-palatal view •Morphological measurements were made using calibrations on radiographs. •Measurements were taken of each tooth: Fig 1.
Most highlighted Results:
•Comparison of the key measurements between molars and bicuspids. Table 1
Knowing this landmark will clinically enable the dentist to find the floor and hence the canals more easily with much less chance of perforation into the furcation.
A: Pulp chamber floor ↔ Furcation
B: Pulp chamber ceiling ↔ Furcation
C: mid point of a line connecting the two cusp tips ↔ Furcation
D: mid point of a line connecting the two cusp tips ↔ pulp chamber ceiling
E: Height of the pulp chamber
