A REVIEW OF

G.V.BLACK’S

CLASSIFICATION

OF DENTAL

CARIES

By: Brenda Marriott RDH,BS

Dental Caries is the result of a pathological disease process caused by the external demineralization of the hard structures of the tooth surface. Caries remain localized and occur after the tooth has erupted thus leaving it susceptible to its environment.

A host environment rich in bacteria, breakdown carbohydrates and sugars into acids. These acids attack the hard structures of the tooth causing decay.

This Power Point will give the student a review of G.V.Black’s Classification of dental caries, which is the standard method used for the identification of carious lesions (cavities), preparations of the site and the restoration itself when completed.

The Purpose

Do to the vast amount of material covered in the Dental Hygiene Curriculum in such a short time, much information is not retained in the students long term memory.

Therefore: A review of G.V.Black’s Classification of Dental Caries would be of benefit the student.

THE PURPOSE: of this Power Point is to help the Dental Hygiene student understand Black’s Classification of Dental Caries which they can access in a non-threatening environment at their own convenience.

The Big Question

Why do I need to know G.V. Black’s

Classification of dental caries?

G.V. Black’s method of the Classification of Dental Caries

is the standard used in the Unites States when referring to

dental decay, cavity preparation, and the name of the

restoration of a tooth. The six categories are numbered by

roman numerals , and are divided into classes based on

the surfaces involved on the tooth. (Wilkins, 2005)

You need to be able to describe where decay is located,

the type of preparation needed to restore the tooth, as

well as the name of the final restoration for patient care,

insurance reporting, documentation, treatment planning

and communication with your instructors, peers and

future co-workers.

You also need it for your State and National Board Exams!

Prerequisites: Admittance into the Dental

Hygiene Program.

Limitations: Computer needed.

Time Frame: None, this review may be

accessed anytime.

Standards:

At the end of this tutorial the student should be able to:

1. State the six classifications of dental caries, and their

locations. (REMEMBERING)

2. Identify the classification of the dental lesion by its location on the tooth surface. (UNDERSTANDING)

3. Choose the correct classification based on the tooth

surface(s) given. (APPLYING))

4. Differentiate the factors involved in determining each

classification. (ANALYZING)

5. Select the classification of caries based on the data

presented. (EVALUATING)

6. Write the correct classification of caries based on the

image provided. (CREATING)

Pre-Assessment Quiz

The Answers

Let see how well you remembered and

identified the six classifications of dental

caries by their locations!

A, Class I

B. Class II

E, Class V

F. Class VI

INCISORS- MAXILLARY LINGUAL

PREMOLARS- OCCUSAL

MOLARS- OCCUSAL

FACIAL

LINGUALS

Marriott,B.2011

(Dozenist, 2006)

Class IILOCATION: PROXIMAL SURFACES

PREMOLARS: MESIAL

DISTAL

MOLARS: MESIAL

DISTAL

(Duran a, 2010)

Class III

LOCATION: Proximal

surfaces that DO NOT

involve the incisal line

angle.

INCISORS- Mesial & Distal

Canines- Mesial & Distal

(Ruprect a, 2010)

Class IV

LOCATION: Proximal Surfaces Involving the incisal line angle.

INCISORS: Mesio-incisal, MI

Disto-incisal, DI

CANINES: Mesio-incisal, MI

Disto-Incisal, DI

(Ruprect a, 2010)

CLASS V

LOCATION: CERVICAL 1/3 OF ALL TEETH(Does not include pit & fissure areas)

(Ruprect a, 2010)

Class VI

LOCATION: Incisal Edges of all

anterior teeth and cusp tips of

all posterior teeth.

(Dozenist, 2006)

CITATION FOR BOTH IMAGES

Ok lets do a little analyzing!

Smooth Surface Caries are Located:CLASS II: Proximal surfaces of premolars & molars

CLASS III: Proximal surfaces of incisors & canines

CLASS IV: Proximal surfaces involving the INCISAL LINE ANGLLS

CLASS V: Cervical 1/3 of facial & lingual surfaces (Not including pit & fissure areaS)

Class VI: incisal edges of all anterior teeth & Cusp tips of all posterior teeth.

Pit & Fissures

These cavities are located on the pit &

fissures of the:

Incisors: Maxillary lingual surfaces

Premolars: Occusal surfaces

Molars: Occusal surfaces

Lingual surfaces

Facial surfaces

Time for Evaluating

Select the classification of caries based on the location of the tooth surfaces given:

1. Proximal surfaces that do not involve the incisal line angle.

2. Incisal edges of anterior teeth and cusp tips of posterior teeth.

3. Maxillary linguals of incisors

4. Proximal surfaces of premolars & molars.
