Como Estan Numerados Los Dientes

Como estan numerados los dientes – Como Están Numerados los Dientes: una guía clara y concisa que desentraña el misterio de la numeración dental. ¡Prepárate para desentrañar el enigma de tus sonrisas!

En el mundo de la odontología, cada diente tiene un número único que lo identifica. Pero, ¿cómo se asigna este número? Este artículo explorará los sistemas de numeración dental utilizados en todo el mundo, desde el Sistema de Numeración Universal hasta el sistema FDI, ofreciéndote una comprensión clara de cómo se numeran tus dientes.

Tooth Numbering Systems

Globally, two primary tooth numbering systems are used to identify and record dental information: the Universal Numbering System and the Fédération Dentaire Internationale (FDI) system.

The Universal Numbering System, also known as the Palmer notation, assigns each tooth a unique number from 1 to 32. The numbers are assigned in a clockwise direction, starting from the upper right wisdom tooth (number 1) and ending with the lower left wisdom tooth (number 32).

The FDI system, on the other hand, uses a two-digit notation to identify each tooth. The first digit represents the quadrant of the mouth, while the second digit represents the position of the tooth within that quadrant.

Comparison of Universal Numbering System and FDI System, Como estan numerados los dientes

Feature	Universal Numbering System	FDI System
Number of digits	One	Two
Starting point	Upper right wisdom tooth	Upper right first molar
Direction of numbering	Clockwise	By quadrant
Example	Tooth number 16: upper left second molar	Tooth number 26: upper left second molar

Quadrant Division

The mouth is divided into four quadrants for the purpose of tooth numbering. These quadrants are:

Upper right quadrant
Upper left quadrant
Lower right quadrant
Lower left quadrant

Each quadrant is assigned a number, with the upper right quadrant being quadrant 1, the upper left quadrant being quadrant 2, the lower right quadrant being quadrant 3, and the lower left quadrant being quadrant 4.The teeth within each quadrant are then assigned numbers, with the first tooth in each quadrant being number 1 and the last tooth in each quadrant being number 8. The teeth are numbered in a clockwise direction, starting from the front of the mouth and moving towards the back.This

system of tooth numbering is used by dentists to identify and locate teeth for treatment. It is also used in dental records and insurance forms.

Permanent Teeth Numbering

The FDI system is the most widely used system for numbering permanent teeth. It is a two-digit system, where the first digit indicates the quadrant of the mouth, and the second digit indicates the position of the tooth within the quadrant.

To number permanent teeth using the FDI system, follow these steps:

Identify the quadrant.The mouth is divided into four quadrants: upper right, upper left, lower right, and lower left. Each quadrant is assigned a number from 1 to 4, as shown in the table below.
Locate the tooth within the quadrant.Each quadrant is further divided into eight sections, numbered 1 to 8. The sections are arranged in a clockwise direction, starting from the front of the mouth.
Combine the quadrant number and the section number.The first digit of the tooth number is the quadrant number, and the second digit is the section number. For example, the tooth in the upper right quadrant, section 5, would be numbered 15.

Permanent Teeth Numbering Scheme
Quadrant	Section 1	Section 2	Section 3	Section 4	Section 5	Section 6	Section 7	Section 8
Upper Right	11	12	13	14	15	16	17	18
Upper Left	21	22	23	24	25	26	27	28
Lower Right	31	32	33	34	35	36	37	38
Lower Left	41	42	43	44	45	46	47	48

Primary Teeth Numbering

Primary teeth, also known as baby teeth or deciduous teeth, are the first set of teeth that develop in children. Unlike permanent teeth, which are numbered consecutively from 1 to 32, primary teeth have a different numbering system. This is because primary teeth are smaller and have a different shape than permanent teeth.

Primary Teeth Numbering Scheme

The primary teeth are numbered using a two-digit system. The first digit indicates the quadrant of the mouth in which the tooth is located, and the second digit indicates the position of the tooth within the quadrant. The quadrants are divided as follows:

-*Upper right quadrant

Teeth numbered 51 to 55

-*Upper left quadrant

Teeth numbered 61 to 65

-*Lower left quadrant

Teeth numbered 71 to 75

-*Lower right quadrant

Teeth numbered 81 to 85

Within each quadrant, the teeth are numbered from the front (incisors) to the back (molars). The following table Artikels the numbering scheme for primary teeth:| Quadrant | Tooth Number | Tooth Type ||—|—|—|| Upper right | 51 | Central incisor || Upper right | 52 | Lateral incisor || Upper right | 53 | Canine || Upper right | 54 | First primary molar || Upper right | 55 | Second primary molar || Upper left | 61 | Central incisor || Upper left | 62 | Lateral incisor || Upper left | 63 | Canine || Upper left | 64 | First primary molar || Upper left | 65 | Second primary molar || Lower left | 71 | Central incisor || Lower left | 72 | Lateral incisor || Lower left | 73 | Canine || Lower left | 74 | First primary molar || Lower left | 75 | Second primary molar || Lower right | 81 | Central incisor || Lower right | 82 | Lateral incisor || Lower right | 83 | Canine || Lower right | 84 | First primary molar || Lower right | 85 | Second primary molar |

Dental Notation

Dental notation is a system used to indicate specific tooth surfaces and areas. It provides a standardized way for dental professionals to communicate and record detailed information about the teeth.

Dental notation consists of two parts: a tooth number and a surface designation. The tooth number identifies the specific tooth in the mouth, while the surface designation indicates the specific area of the tooth being referred to.

Tooth Numbering

Teeth are numbered according to their position in the mouth. The numbering system is based on the Universal Numbering System, which assigns each tooth a unique number from 1 to 32. The numbers are assigned as follows:

Permanent teeth:Numbers 1-32, starting from the upper right wisdom tooth and proceeding clockwise around the mouth.
Primary teeth:Numbers A-T, starting from the upper right primary central incisor and proceeding clockwise around the mouth.

Surface Designation

The surface designation indicates the specific area of the tooth being referred to. The following surface designations are commonly used:

Occlusal (O):The chewing surface of the tooth.
Buccal (B):The cheek side of the tooth.
Lingual (L):The tongue side of the tooth.
Mesial (M):The surface of the tooth that faces towards the midline of the mouth.
Distal (D):The surface of the tooth that faces away from the midline of the mouth.

Examples of Dental Notation

Here are some examples of dental notation:

16O:The occlusal surface of the upper right first molar.
27B:The buccal surface of the lower left second molar.
A3M:The mesial surface of the upper right primary canine.
