TOPIC: CLASSIFICATION OF TEETH BASED ON THEIR NORMAL POSITION 
KEY POINTS FOR COMPLETE HUMAN DENTITION 
DENTITION: Refers to all the teeth present in the mouth. TWO SETS OF DENTITION Types of Dentition: Primary Dentition (childhood). Permanent Dentition (adulthood, also called secondary dentition). DENTAL ARCHES: Maxillary Arch: Formed by teeth in the […]
Spillway Spaces (Interproximal Spaces/Embrasures): 
Spillway spaces are triangular-shaped spaces adjacent to the contact areas of teeth. Spillway spaces, also known as interproximal spaces or embrasures, are the triangular spaces between adjacent teeth, located gingival to the contact point.
REPARATIVE DENTIN: Reparative dentin, also known as tertiary dentin, is formed in response to external stimuli such as trauma, caries, attrition, or dental procedures. It is produced by odontoblasts that survive the injury or by newly differentiated odontoblast-like cells.

To identify a specific tooth, arch, quadrant, and the tooth’s name. Currently, only three most popular systems are favored worldwide. These popular systems are as follows: • The Zsigmondy/Palmer (the eight-tooth […]
