Question

How many lobes do MANDIBULAR FIRST MOLARS have?

Answer 1

Mandibular first molars have three lobes: the mesiobuccal, distobuccal, and lingual lobes.

Step-by-step explanation:

Mandibular first molars have three lobes: the mesiobuccal, distobuccal, and lingual lobes.

1. The mesiobuccal lobe is located on the mesial side of the tooth and is the largest lobe. It has a slightly curved occlusal surface and two cusps: the mesiobuccal and mesiolingual cusps.
2. The distobuccal lobe is located on the distal side of the tooth and is smaller in size. It has a straight occlusal surface and one cusp: the distobuccal cusp.
3. The lingual lobe is located on the lingual side of the tooth and is smaller than the mesiobuccal lobe. It has a convex occlusal surface and one cusp: the lingual cusp.

Overall, mandibular first molars have a total of five cusps and three lobes.
