Which cusp is the tallest on mandibular first molars?

The correct answer is: ML

The tallest cusp on mandibular first molars is the ML (mesiolingual) cusp. In the mandibular first molar, the ML cusp is typically the tallest and most prominent cusp on the lingual side. This cusp plays a key role in the occlusal and chewing function of the tooth. In comparison to the other cusps listed in the question: - The DL (distolingual) cusp is usually shorter than the ML cusp. - The MB (mesiobuccal) cusp is larger than the DL cusp but is not the tallest on the mandibular first molar. - The DB (distobuccal) cusp is located on the buccal aspect of the tooth and is typically shorter than the ML cusp. Therefore, the correct answer is the ML cusp because it is generally the tallest cusp on the mandibular first molar.
