Universal 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.

There is a need for the dentist to record the information on the tooth at a specific tooth.  So that every dentist can get the same meaning, the system used has to be universal for them all.  Since each number is assigned to each tooth, it is hard to make a mistake.  The data can also be entered easily into the computer and even if the system can be difficult for the beginners to follow, they will get it with extra training. It is easy to communicate using this system. For primary teeth, A is for Maxillary right second molar, the J stands for the maxillary second molar at the left, while K is found at the Mandibular second molar on the left and T stands for Mandibualar second molar on the right.

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 which had been approved in America and the number used is designed for a specific and certain tooth and it reduces the confusion.   During the charting, a tooth will be referred to using a number and not a name.   The arrangement is important to the dental officers and their assistant because they will see the sides when they are reversed when they look in the mouth of the patient.  With the information, the dentist can locate the tooth easily and can work on it as required.

How Universal Dental Notation is used

The dental chart is used according to a viewpoint of the dental practitioner while facing the patient. The right side of the patient does appear at the left side of a chart while the left side of a patient will appear at a right side of a chart. When the dentists label a side left or right, it will be reflecting the left or right side of a patient.

The lower right starts with 32, 31, 30, 29, 27, 26 and 25

The lower left starts at 24, 23, 22, 21, 20, 19, 18 and 17

For the primary dentition

The upper right starts at A, B, C, D and E

The lower right starts with T, S, R, Q and P

Excellent service. Great first impression! Best cleaning I've had in several years, my mouth feels amazing. They even took the time to show me how to brush more effectively. My teeth are back to being pearly white. They were very knowledgeable in regards to my insurance and I've had no issues. The service there is impeccable!

The staff is wonderful, very friendly and informative. I love how they not only take X-rays, but also photos of all your teeth and put them on the big screen. They spent as much time as I needed to go over each area and explain specifics of each tooth. I definitely have a greater understanding of what is going on in there and what I need to do. I also love their space, it has a calming vibe with all kinds of artwork on display. You almost feel like you’re not at the dentist! Thank you all so much, I look forward to seeing you all again! (Said no one to their dentist 😉 )

I am not the biggest fan of the dentist, however this was the BEST dentist experience I have ever had! Everyone was so kind and I got everything I needed done in one visit! They provided super helpful insight about what was going on with my teeth and took care of everything I needed quickly. I will absolutely be returning! 🙂

Beautiful location and office. Very friendly and welcoming staff! I had a great time conversing with them about movies and music. Dr. Nguyen and his staff were very knowledgeable and stressed the importance of making sure the patient knew what their game plan was. The office is very high tech as well so it was super cool to know that I was getting the latest tech being use on me.

Love the location, the dentist AND the staff. Everyone there is awesome. It's rare that I leave a dentist office feeling just as good as when I arrive. I was sad I didn't get to see Snickers, but all in all I had a great experience my first time here. Glad to finally have a new "home" dentist since moving to Texas.

From start to finish great experience. Impeccably clean office, high tech tools, & friendly staff. Went to get my top teeth contoured/shaped. They did a Hollywood star job! I now, have a flawless smile. I even went back the next day for a touch-up on one tooth & they took care of it, graciously. If you want quality cosmetic dentistry inside the loop; look no further. These folks are the best in class.

Very friendly staff. The hygienist's were so knowledgeable and really took the time to teach you about your teeth, they gave my husband and I "homework" to improve our oral health. Love it! Angela was great, great sense of humor (made me laugh a lot) and very professional. Awesome job Nicole, very friendly and took the time to answer all the questions we had (love she was recommending eateries for hubby to take me :). Julia was great at the front counter very lively and knowledgeable as well. They all really took the time and customized everything for us. Able to get free electric toothbrushes but didn't have any in stock.

I am usually scared of going to the dentist for my annual cleaning but I was completely blown away by the amazing customer service from the staff. Julia was extremely helpful and explained my dental coverage and out of pocket costs. Angela did an exceptional job explaining to me about the importance of dental hygiene and actually taught me how to floss properly. The office was extremely clean and upscale. Dr. Bridget was very sweet and great bedside manners. She explained everything about the treatment plan in a very thorough and concise manner. I was extremely impressed by everyone on the office and I cant wait to come back for my next appointment.

Great place for all your dental needs. Very inviting and friendly staff. They are very knowledgeable and passionate about the work they do. I've been looking for a good dentist for awhile while neglecting my oral health, but now I think I've found my place. 10/10 would come back for a follow-up appointment.

Very friendly staff who put up with my inane sense of humor. The entire team team spoke with me 1:1, including:Dental assistants, hygienist, dentist, and insurance admin (explained everything to me in detail including how my insurance works).They explained my x-rays to me, the effects of flossing correctly / incorrectly. I feel like they gave me the education I didn't get as a child on how to care for my mouth, and why it's important. I was doing good stuff for my oral health-- just not correctly or with a positive attitude.GREAT aftercare package.
