Study Notes
Permanent Molars Overview
- There are three pairs of permanent molars in each quadrant, totaling twelve permanent molars.
- Permanent molars are considered posterior teeth.
Eruption Timing and Characteristics
- Permanent maxillary molars typically erupt between ages 6 and 12.
- These molars are characterized by four or five surfaces, including buccal, lingual, mesial, distal, and occlusal surfaces.
- Permanent maxillary molars generally have three roots: two buccal and one palatal.
Occlusal and Root Structure
- The first permanent maxillary molar has a hexagonal or rectangular occlusal outline.
- The buccal aspect of permanent maxillary molars is best described as having a trapezoidal geometric outline.
- An important anatomical landmark on the buccal surface is the buccal groove.
Additional Facts
- Permanent maxillary molars have a rhombus-shaped occlusal outline.
- Upper molars possess three roots, while lower molars have two roots.
- The occlusal outline of upper molars can also be described as either ovoid or rectangular.
- Permanent maxillary molars have a total of five surfaces.
- The cervical outline of the buccal aspect is slightly concave toward the root.
