Study Notes
Basic Characteristics
- Permanent molars total 12 (6 maxillary, 6 mandibular)
- Located at the 6th, 7th, and 8th positions from the midline
- Classified as first, second, or third molars
- Are non-succedaneous teeth
Eruption Timeline
- First molar: erupts around 6 years of age
- Second molar: erupts around 12 years of age
- Third molar (wisdom tooth): typically erupts between ages 17 and 22
Primary Functions
- Mastication (chewing)
- Maintaining the vertical dimension of the face
- Maintaining the arch continuity for proper alignment
- Supporting the cheeks (aesthetic function)
General Molar Characteristics
- Developmental lobes match the cusps
- Maxillary molars have 3-5 lobes
- Mandibular molars have 4-5 lobes
- Height of contour
- Facial: cervical third
- Lingual: middle third
- Contact points
- Mesial: near the junction of the middle and occlusal thirds
- Distal: closer to the cervical line, near the middle of the tooth
Maxillary First Molars (#3 and #14)
- Widest tooth buccolingually
- Features:
- Four large cusps (MB, DB, ML, DL)
- A common fifth cusp (Cusp of Carabelli) on the lingual surface
- A prominent oblique ridge
