The maxillary first molar typically has three roots: the mesiobuccal, distobuccal, and palatal roots. The palatal root is generally the largest and longest, while the mesiobuccal root commonly contains two canals—MB1 and MB2. The distobuccal root usually contains a single DB canal, and the palatal root contains a single P canal.

A sound understanding of this root and canal morphology is essential for accurate diagnosis, endodontic access, canal location, and successful root canal treatment.

Remember: 3 roots, commonly 4 canals — MB1, MB2, DB and P.

🦷 Five cusps. One classic Y. Can you identify them all?

The 5-cusp mandibular first molar is recognized by:
🔹 Mesiobuccal cusp
🔹 Distobuccal cusp
🔹 Distal cusp
🔹 Mesiolingual cusp
🔹 Distolingual cusp
🔹 Characteristic Y-shaped groove pattern

💡 Opathlearners Tip: The distal cusp is the smallest cusp and helps give the mandibular first molar its characteristic 5-cusp appearance.

Save it. Spot it. Remember it. 🦷✨
