So the upper right teeth begin with the number “1” (i.e. 11), the upper left teeth begin with the number “2” (i.e. 21), the lower left teeth begin with the number “3” (i.e. 31), and the lower right teeth begin with the number “4” (i.e. 41)..
What are the 2 numbering systems in dentistry?
The three most common systems are the FDI World Dental Federation notation (ISO 3950), the Universal Numbering System, and the Palmer notation..

What is the Palmer tooth nomenclature?
The Palmer notation consists of a symbol (⏌⎿ ⏋⎾) designating in which quadrant the tooth is found and a number indicating the position from the midline.

Gross Anatomy

There are twenty deciduous (primary) teethin young children, with ten per jaw and five in each quadrant, which consist of (distal to mesial): 1. two molars 2

Arterial Supply

Arterial supply to the teeth is derived from the maxillary artery, a branch of the external carotid artery, via the: 1. superior alveolar arteries 1.1

Venous Drainage

Venous drainage of the teeth is into either the: 1. pterygoid venous plexus, or 2. facial vein via vessels that generally follow the arteries

Innervation

1. the maxillary teeth are supplied by a group of superior alveolar branches … 2

Variant Anatomy

1. hyperdontia: supernumerary teeth 2

Radiographic Appearance

The teeth are well visualized on these modalities 1-3: 1. enamel: most radiopaque part, hardest tissue in the human body 2

Related Pathology

1. edentulism 2. dental (periapical) abscess 3

Therefore, the notation UR1 indicates the permanent right upper central incisor

What is the alphanumeric system of dental notation?
