Introduction

Increase in computer applications to store information, as well as through the data cable, printer paper and the oral presentation of oral information exchange will to increase resistance, making it necessary to describe the dental positioning system, a new set of basic elements.

The standard system described initially prepared by the International Dental Federation (FDI), and access to the World Health Organization (WHO) and ISO/TC106 dental science and technology committee agreed to meet the following requirements.

a) easy to understand and easy to professor;

b) dialogue and oral easy to pronounce;

c) when printing and easy through the data cable to communicate;

d) easily translated into a computer "input";

e) in the dental clinical easily attached to the standard layout.

Dentistry teeth and mouth area designation method

1 Scope

This standard specifies the double digit mark teeth or oral area approach.

2 Principles

With respect to the sagittal plane and bite, normal anatomical location of the dental arch can be reasonably mouth into four equal parts, and six equal parts.

This standard, a quadrant (1/4) represents a quarter of the dental arch.

This standard, 1/6, represents one-sixth of the dental arch.

Teeth and mouth area to double-digit coding marked.

At least one of the two numbers is "0", it is meant oral area.

9 replaced by a 0 indicates there is an abnormality in the oral region.

Encoding does not contain 0 represents a single tooth. Wherein the encoding of the first digit indicates the quadrant where the teeth and the deciduous and permanent phase Distinction, second digit indicates tooth itself.

3 Oral Regional Flag

Oral region marked in Figure 1.

00 represents the whole mouth 01 represents maxillary region 02 represents the mandibular region 10 represents the upper right quadrant 20 shows the upper left quadrant 30 shows the lower left quadrant 40 shows the lower right quadrant 03 represents the upper right 1/6

04 Indicates the front 1/6

05 for the upper left 1/6 06 represents the lower left 1/6 07 represents the front 1/6 08 represents the lower right 1/6 4 teeth tooth mark Teeth teeth indicated in Figure 1.

a) The first digit

Numbers 1-4 indicate permanent dentition, digital 5-8 represents deciduous dentition. The oral representations were made from the upper right region starting clockwise Ascending.
