How well do you know the complex anatomy of the maxillary first molar?

• Maxillary first molar is the largest tooth in volume and has complex root and canal anatomy.
• Four pulp horns are present in the pulp chamber.
• The pulp chamber's cervical outline form has a rhomboid shape.
• The mesiobuccal angle is an acute angle, the distobuccal angle is an obtuse angle, and the palatal angles are right angles.
• The orifices of the palatal, distobuccal, and mesiobuccal canals form a triangle known as the molar triangle.
• The palatal root curves buccally at the apical one-third.
• The mesiopalatal canal orifice is located palatal and mesial to the mesiobuccal orifice.
• The orifice of the mesiobuccal canal can be round, oval, or flat.
• Videos and scans are available online for rotational views of the teeth.
• The maxillary first molar is one of the most complex teeth in terms of anatomy.
