Study Notes
Anterior Teeth
- There are 12 anterior teeth in permanent dentition.
- Anterior teeth can be replaced by succedaneous teeth, which correspond to the same type of primary teeth.
- The cingulum is a rounded, raised area found on the cervical third of the lingual surface of anterior teeth.
- Newly erupted central and lateral incisors feature mamelons on their incisal ridge, a distinctive characteristic.
Canines and Centrals
- Canines are the longest teeth in the permanent dentition, designed for tearing food.
- Mandibular centrals are the smallest teeth in the permanent dentition, known for their narrow and simple morphology.
Surface Features of Teeth
- Imbrication lines are the developmental horizontal lines that can be observed on anterior teeth, signifying enamel formation.
- Marginal ridges serve as boundaries for the occlusal table on posterior teeth.
- A pit is defined as a pinpoint depression located where two or more grooves intersect.
Tooth Extraction and Occlusal Forms
- Third molars, commonly known as wisdom teeth, are often extracted during orthodontic treatments due to space issues.
- The mandibular second premolar can appear with configurations resembling two cusps or three cusps, affecting its occlusion.
Root Structure
- The area where three roots divide is referred to as trifurcation, which is significant for understanding molar anatomy.
- Mandibular molars typically possess two roots, critical for their stability and function.
Primary Teeth Characteristics
- Permanent dentition uses an alphabetical method of identification for primary teeth in the Universal/National System.
- The maxillary molar features an H-shaped groove pattern on its occlusal surface, distinguishing it from other primary teeth.
- The largest primary tooth is the mandibular molar, which is larger than its maxillary counterpart.
- The enamel of a primary tooth is relatively thin, which can influence dental health and development.
Unique Cusp Features
- The cusp of Carabelli is an additional cusp found on the maxillary first molar, adding to its complex anatomy.
