Study Notes
Premolars
- The Max 2nd Premolar is the first to show evidence of calcification
- The crown of the Max 2nd Premolar completes at around 2-2.5 years of age
- The buccal view of the Mand 2nd Premolar is oval in shape
- The Max 1st Premolar erupts between 9-11 years of age
- The Mand 2nd Premolar has the largest crown size buccal-lingually
- The occlusal view of premolars is oval or elliptical in shape
Canines and Incisors
- The Maxillary canine is the last to erupt and complete root development among the anterior teeth
- The crown of the Maxillary canine completes at around 4-5 years of age
- The Mandibular lateral incisor has a root tip that generally tips distally
- The Mandibular lateral incisor has a larger facial-lingual root and crown dimension
- The Mandibular lateral incisor takes the longest time for the crown to fully mature
- The Mandibular central incisor is the first to erupt among the anterior teeth
- The Mandibular central incisor has the shortest time for root completion
- The Mandibular lateral incisor has a lingual fossa that is smaller but deeper than the maxillary central incisor
- The Mandibular lateral incisor has a mesial cervical curvature that is slightly greater than the distal cervical curvature
- The Mandibular lateral incisor has a distal marginal ridge that is not as concave as the mesial marginal ridge
- The Mandibular lateral incisor has a lingual view with landmarks that are generally less prominent
- Newly erupted Mandibular central incisors have mamelons on the incisal surface
Other Dental Structure
- The height of contour (HOC) is located at the junction of the middle and cervical thirds on the facial-lingual surface of anterior teeth
- The Mandibular central incisor has the smallest permanent crown among the incisors
- Proximal contacts in dentition serve to separate adjacent teeth and guide the development of the dentition
- The articular disc separates the articular surfaces of the mandibular fossa and condyle
- The degree of overjet and overbite can be assessed from the facial surface of the maxillary central incisors
- Edge-to-edge bite is characterized by zero vertical overlap of the anterior teeth
