Premolar Dental Anatomy Quiz

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
