GV BLACK CLASSIFICATION of Dental Caries – Everything You Want To Know

When I was in my 2nd year of BDS I used to assist interns when they took OPD in the Department of conservative dentistry and Endodontics. I saw them writing, along with dental caries they had added the term “Class I dental caries or Class II dental caries, etc”.

Then I asked one of my interns why you didn’t just write only dental caries. She told me that, we have to specify which type of caries it is like, whether including the proximal wall or incisal area or gingival third or occlusal caries.

Her case sheet looked like this:

“Class II dental caries irt 26

Class III dental caries irt 11

Class IV dental caries irt 21

Class V dental caries irt 12

etc….”

This made me think more and when I reached my room I opened Sturdevant text book.

Before going to this let me explain briefly about dental caries and some terms used.

Basics About Dental Caries

According to Sturdevant dental caries is defined as ” Irreversible microbial diseases of the calcified tissue of the teeth charectorised by demineralisation of inorganic portion and distruction of the organic substance of the tooth which leads to cavitation”.

Before I explain the classification I would like you to know about different tooth surfaces, without which you won’t be able to understand GV Black’s Classification.

If you are aware of the same, then you can skip to the next section.

Occlusal: The area of the tooth used for grinding or chewing. occlusal surface in GV black classification
Lingual: The region of a tooth’s surface that faces and is closest to the tongue. lingual surface in GV black classification
Buccal: The tooth’s crown that is closest to your cheeks. Buccal surface in GV Black classification
Proximal: The area where adjacent tooth surfaces are located Proximal surface in GV Black classification

What is GV Black Classification?

There are many classifications for dental caries and the most accepted one is GV Black’s Classification.

GV Black has introduced a classification for dental caries which is widely used in dentistry and is based on the location of the caries of the tooth. Dental caries can be classified into 6 classes from Class I to Class VI based on the location of the caries.

Who is GV Black?

GV Black Father of Operative Dentistry

GV Black also known as Green Vardiman Black was the founder of modern dentistry. He has many research projects in dentistry like dental fluorosis, cavity preparation, and tooth preparation. According to his principle of tooth preparation the phrase” extension for prevention” is still famous in the dental community today.
