Which permanent tooth typically has the longest root in the dentition?

Which permanent tooth most commonly has two roots, one buccal and one lingual?
Answer: Maxillary first premolar
The maxillary first premolar is usually bifurcated into buccal and lingual roots.
The most common occlusal groove pattern of the three-cusp form of the mandibular second premolar is:
Answer: Y pattern
The three-cusp mandibular second premolar shows a Y-shaped groove pattern, while the two-cusp form shows H or U patterns.
The oblique ridge of the maxillary first molar connects which two cusps?
Answer: Mesiolingual and distobuccal
The oblique ridge runs from the mesiolingual cusp to the distobuccal cusp.
Which primary tooth most closely resembles the permanent mandibular first molar?
Answer: Primary mandibular second molar
The primary mandibular second molar has five cusps and closely mimics the permanent mandibular first molar it precedes.
Which root of the maxillary first molar most frequently contains a second canal (MB2)?
Answer: Mesiobuccal root
The mesiobuccal root is broad buccolingually and commonly contains a second mesiobuccal canal.
