What is Dental Notation?
Dental Notation is a language used by dental professionals when they are writing about their finding and they use many dental notation systems in order to show the associated information on a certain tooth. There are 3 common methods; they are Palmer Notation Method, Universal Numbering System and ISO system. ISO system is the one used in the entire world while Universal method is used mostly in United States. ISO system may be adapted and entered into the computer.
What it is Universal Dental Notation?
Even if it is called universal, it is used mostly in the United States only. Some also call it the American system to count teeth whether they are primary or permanent teeth. The doctor use upper case letters, starting at A to T and they are meant to show primary teeth and 1-32 are used to record the permanent teeth. The tooth recorded as 1, it is a maxillary right third molar also known as wisdom tooth. This count will continue to reach to upper teeth at the left side. The count will start again at Mandibular left third moral which is designated like the number 7. This continues to reach to a bottom tooth at its right side. Every tooth is given a certain letter or a number which can be entered by the keyboards.
What is the history in relation to counting teeth
Before, people were using the notation from German and Latin. The names given were lengthy. For example, when writing about Molaris Secundus Superior Sinister, they would write Mol II Scup Sin. Afterwards, Adolf Zsigomondy came up with the system where the tooth were put in four sets and each set had eight number and can be identified at the Zsigmondy grid which is used for the permanent dentition alone. After some years, the system got modified and it was used also with the primary dentition.
A Hillischer system that was being used to refer to a tooth type, it is logical but at the same time confusing since the colons or semi colons where used to distinguish permanent and primary teeth. The next system was the use of Mons Dubois system which would show odd numbers and even number. They were to represent the left and right quadrant. Afterwards, the Universal numbering system came out and it is the official system used in America and it started to be used since 1975, when American Dental Association adopted it.
With the Universal Dental Notation for the permanent teeth, all teeth will be numbered regardless if they are in or not. In case the wisdom tooth is not there, then the first number is going to be 2 and not 1. This is to acknowledge that there is a missing tooth
Who Needs The Universal Dental Notation?
The Universal Dental Notation is the system approved in America, and the number used is designed for a specific and certain tooth. It reduces confusion. During teeth numbers and names charting, a tooth will be referred to using a number, not a name. The arrangement is important to the dental officers and their assistants because they will see the sides when they are reversed when they look in the mouth of the patient. The dentist can locate the tooth easily and work on it as required with the information.
How is Universal Dental Notation used?
The teeth number chart is used according to the viewpoint of the dental practitioner while facing the patient. The patient’s right side does appear on the left side of a tooth numbers chart, while the left side of the patient will appear on the right side of a dental tooth chart. When the dentists label aside left or right, it will reflect a patient’s left or right side.
What Is The Purpose Of The Teeth Numbering Chart?
- Numbered teeth charting is vital to document health and disease in a way that may use both now and in the future.
- A tooth numbering chart helps to gather essential data before therapy to know what teeth and pathology were present for medico-legal protection reasons.
- Without collecting the necessary data during the beginning of treatment, it is hard to assess the effectiveness of treatment over time.
- A teeth names chart is a wise clinical practice to adopt. The customer is frequently astonished by the effort to compile knowledge they can easily comprehend and apply to their part in maintaining the oral cavity.
Understanding The Tooth Numbering Chart
A dental tooth number chart identifies each tooth according to the Universal Numbering System. The Dental tooth number chart can help determine the number of teeth present in an individual’s mouth by breaking down the total number of teeth into components. It will help you to know the number of wisdom teeth, upper and lower incisors, upper and lower canines, upper and lower first premolars, upper and lower second premolars, upper and lower third premolars, upper and lower fourth premolars, upper and lower molars on both the left and right sides of the mouth.
