Trainee information

Before you start

The assessor/observer will talk about what you need to do.

You may have been observed doing some of these tasks already, or there may be workplace documents you have completed, such as a workplace incident report, which documents what you have done at work.

You need to provide a portfolio of evidence from your work to show how you have charted teeth and restorations for a patient.

As you go

Answer all questions. Refer to real situations when answering questions.

For knowledge assessment questions you can choose to write your answers or your assessor may record your verbal answers for you.

If you need help with this assessment, please contact your assessor.

Definitions The word trainee in this assessment refers to you, the person being assessed. Other terms that may be used are candidate, student or employee.

An organisation’s policies and procedures are the policies and procedures of the employer and include ethical codes, standards and other organisational requirements.

Codes are an agreed set of foundation or guiding principles established by a health or wellbeing service provider, professional organisation or regulatory body. These may include organisational codes of conduct or ethics, codes of rights, a professional association's codes of conduct, rules, or ethics, and international conventions.

Codes of practice relevant to this unit standard are set by the Dental Council of New Zealand and are available at www.dcnz.org.nz and search for practice standards

Patient refers to a person accessing dental services. Other terms used for the patient may include client, consumer, individual, or tūroro.

A workplace assessor or assessor is the person who will assess you.

An observer is someone who understands the assessment, works closely with you and can confirm that you have performed the task competently.


Task 1: Tooth structure and surfaces You need to describe the tooth structure and the location of the tooth surfaces.

1 Match the component of the tooth and their descriptions to demonstrate knowledge of tooth structure. Draw a line or put the description number in the answer box for the correct component.

Tooth component Answer Description

enamel 1 This is the layer under the enamel. It forms the bulk of the tooth. It is a hard, thick layer but is not as hard as the enamel. It is elastic, compressible and sensitive. It is ‘live‘ tissue.

dentine 2 This is a thin, fibrous ligament attached to the cementum that connects or holds the tooth in its socket. Teeth are suspended in their sockets by the fibres of the ligament. This allows each tooth a little movement. The fibres of the ligament act as shock absorbers to cushion some of the impact created by chewing.

pulp 3 This is the smooth, shiny, outer layer of the tooth. It helps to protect the tooth. It is the hardest material in the body and this makes it able to break apart food during chewing. It gives teeth their white colour.

cementum 4 This helps to anchor the teeth in their correct position in the mouth. The buds of the baby and permanent teeth are formed in the jawbones well before the teeth eventually appear.

periodontal ligament

5 This is the living part of the tooth and is very sensitive. It forms the central chamber of the tooth. It is made up of nerves and blood vessels and other soft tissues.

jawbone 6 This is the part of the tooth that is below the gum. It cannot be seen. The root anchors the tooth in the jawbone.

crown 7 This is a thin layer of a hard bone-like substance that covers the dentine of the root. It helps to hold the root of the tooth in the jaw.

root 8 This is the part of the tooth that can be seen above the gum. It has a coating of enamel that protects the dentine underneath.


2 Identify the components of the tooth structure on the diagram by labelling the parts of the tooth indicated by the lines.


3 Match the five tooth surfaces with their location on the tooth. Draw a line or put the description number in the answer box for the correct surface.

Tooth surface Answer Location

occlusal or incisal surface

1 This is the surface that faces the inside of the mouth. On the upper teeth it is the palatal surface. On the lower teeth it is the lingual surface.

mesial surface 2 This is the surface of the tooth that is distant from the mid-line of the tooth arch, facing the back of the mouth. It is the back side of the tooth.

distal surface 3 This is the cutting or chewing edge on the top or biting surface of the posterior teeth. It is the bumpy surface that does the chewing. Incisors and canines have an incisal edge. This is the cutting edge or surface of the tooth.

lingual or palatal surface

4 This is the outside surface. It is the surface that faces the cheek and what people see when they look at you.

facial surface – buccal and labial

5 This is the surface of the tooth nearest to the mid-line of the tooth arch. It faces the front of the mouth.

Task 1: Assessor’s feedback to trainee

When the assessor agrees that you have completed this task successfully, they will sign it off on the assessment summary page at the front of this assessment.


Task 2: Dental notation In this task you must describe tooth notation in terms of the FDI World Dental Federation system of notation.

1 Describe the quadrant notation used by the FDI World Dental Federation notation system. Include the quadrant numbering.

2 What is meant by two digit notation, within the FDI World Dental Federation Two-digit notation (ISO-3950 notation)?


3 You need to show that you have charted teeth and restorations using the FDI World Dental Federation system of notation. Evidence must be gathered in the workplace. You need to put together a collection of your evidence, called a portfolio of evidence.

Portfolio of evidence

Note to observer or assessor: You have been asked to confirm that you have sighted and reviewed the trainee’s portfolio of evidence showing that they have charted teeth and restorations using FDI World Dental Federation system of notation.

Procedures must follow the Dental Council of New Zealand’s Patient Information and Records Practice Standard. [EN 4]

The following samples of evidence should be attached. Remember to remove identifying details to maintain the patient’s privacy.

Assessor/observer to complete

Tooth notation

Attach sample (printed or screenshot) of a patient’s record showing tooth notation and restorations using FDI World Dental Federation system of notation.




Task 3: Dental caries and periodontal disease In this task you must describe the causes, symptoms, progression and management of dental caries and periodontal disease.

1 Describe the causes and symptoms of dental caries.

2 Match the description with the five stages of progression of dental caries. Draw a line or put the description number in the answer box for the correct stage.

Stages of dental caries

Answer Description

early 1 The decay spreads into the pulp and the pulp becomes inflamed.

moderate 2 The tooth enamel is dissolved by acids. Signs that a dental caries is forming include a chalky white spot on the surface of the tooth and/or a brown discolouration. A cavity (hole) will form.

advanced 3 This forms at the top of the root. In highly advanced cases, the infection can spread from the tooth to the surrounding soft tissues and make the person seriously ill.

necrosis 4 The enamel is worn away to expose the dentine. Bacteria enter the cavity. The person’s tooth may start to hurt, and they may be sensitive to changes in temperature and sweet flavours, and have bad breath.

abscess 5 The pulp tissue dies.


3 Describe the causes and symptoms of periodontal disease.

4 Match the description with the four stages of progression of periodontal disease. Draw a line or put the description number in the answer box for the correct stage.

Stages of periodontal disease

Answer Description

gingivitis 1 As the infection worsens, the pockets deepen. The periodontal ligament becomes inflamed along with the alveolar bone. The gums and bone start to break down.

early periodontitis 2 Plaque and tartar form around the gum line and cause inflammation of the gums.

moderate periodontitis

3 Untreated gingivitis can lead to periodontitis or inflammation around the tooth. This can cause infection.

advanced periodontitis

4 Once there is so much bone loss that the tooth is no longer anchored, the tooth becomes loose. It either falls out or needs pulling out by a dentist or oral surgeon.


5 Describe the management of dental caries and periodontal disease by matching the person responsible for the following actions.

Indicate which of these actions are done by the person, and which by an oral health care professional. Draw a line or put the action numbers in the answer box relating to the person responsible.

Responsibility of: Answer Action taken to manage dental caries and periodontal disease

the person 1 Brushing teeth at least twice a day and using a mouth wash.

2 Periodontal surgery.

3 Avoiding sugary foods and drinks and limit amounts of sugar.

4 Low dose oral or topical antibiotics.

the oral health care professional

5 Removing areas of decay and infection.

6 Using sugar-free chewing gum to stop plaque build-up.

7 Cleaning, scaling and root planning.

8 Flossing teeth daily.

9 Protecting the tooth by filling it or applying a sealant.
