Which molar has the longest roots of all molars?
maxillary first molar
mandibular first molar
mandibular second molar
maxillary second molar
The correct answer is: mandibular first molar
The mandibular first molar is known to have the longest roots of all molars. This is because the mandibular first molar is the first molar that erupts in the permanent dentition, and it plays a crucial role in providing stability and support to the occlusion. Additionally, the mandibular first molar typically has three roots - two buccal roots and one lingual root, which contribute to its overall root length. In contrast, the other options are incorrect because: - The maxillary first molar (Option A) usually has three roots but they are generally shorter compared to the mandibular first molar roots. - The mandibular second molar (Option C) usually has two roots that are shorter than those of the mandibular first molar. - The maxillary second molar (Option D) typically has three roots but they are also shorter than those of the mandibular first molar.
