Study Notes
Dental Development and Dentition
- The permanent dentition begins to erupt around 6 years of age.
- Primary teeth, also known as deciduous teeth, are formed in utero and are completed around 3 years of age.
- The transition to mixed dentition occurs between 6-12 years of age.
- The Universal Numbering System starts with the upper right third molar and progresses to the upper left third molar for permanent teeth.
- The upper arch is referred to as the maxilla, and the lower arch is referred to as the mandible.
Tooth Structure and Function
- The incisal edge is the surface of a tooth used for cutting in an anterior tooth.
- The occlusal surface is the surface of a tooth used for chewing in a posterior tooth.
- The contact point is the surface of a tooth responsible for preventing the lodging of food.
- Marginal ridges serve to prevent the lodging of food in the contact point.
Primary Dentition
- There are 20 teeth in the primary dentition.
- The primary dentition phase begins at birth and ends with the exfoliation of the last primary tooth around 12-14 years old.
- The primary maxillary central incisor is the first tooth to erupt, and the primary mandibular second molar is the last tooth to erupt.
Tooth Characteristics
- The primary mandibular second molar has almost equal-sized cusps.
- The primary maxillary first molar has a triangular ridge on the occlusal surface that terminates at the Central Developmental Groove (CDG).
- The primary maxillary lateral incisor has a distal root that is rounder, shorter, and more tapered.
- The primary mandibular canine has a lingual cusp that is almost centered lingually and in line with the mesial root.
Developmental Anomalies and Pulp
- The formula for estimating the timing of enamel hypoplasia is: Age (in years) = Crown height (mm) / 3.6 + 1.6.
- Developmental anomalies in dental roots can occur due to genetic or environmental factors.
- The dental pulp's primary function is to produce dentin and respond to stimuli.
- The cementoenamel junction (CEJ) is the boundary between enamel and cementum on the root surface.
