Q3: Which of the following are the morphological characteristics of maxillary first premolar?
hmmm
A. presence of pulp horn under each cusp
B. larger palatal orifice compared to buccal orifice
C. pulp chamber wider buccolingually than mesiodistally
D. all of the above
Answer: all of the above
Q4: Compared to the buccal pulp horn, the lingual pulp horn is larger in the mandibular first premolar and
smaller in the mandibular second premolar.
As the mandibular second premolar has a smaller lingual inclination compared to the mandibular first
premolar, less extension up the buccal cusp is needed to achieve a straight-line access.
