1. Question 1 DN15 1.1,1.2 LO1 range 1a-f, LO2 range 1a-f
Describe these types of oral diseases and their aetiology
Caries These are the cavity due to tooth decay and is caused due to
bacterial infection.
Gingivitis It is known as the inflammation of gums. The main cause of
Gingivitis is the presence of bacterial plaque around or between
the teeth.
Periodontal Disease This gum disease results in inflammation. The progression of
Gingivitis cause peridontal disease which can also cause loss of
teeth.
Erosion Tooth erosion is defined as the condition when tooth enamel is
washed away by excessive acid. The main cause of this disease
is excessive consumption of drinks containing acid such as fruit
drink or soft drink.
Abrasion It is known as the damage or loss of protective tooth layer
which is caused due to chemical and mechanical wear.
Document Page
Attrition Attrition is type of tooth wear resulting in loss or damage of
tissues of tooth. The major cause of this disease is tooth to tooth
contact.
2. DN15 1.3.1.4, 1.5, 1.6, 1.7
Document Page
Describe in detail the following:
1. The progression of dental caries.
2. The progression of periodontal disease.
3. The development and composition of plaque.
4. The inflammatory process.
5. The effects of the disease process.
1
The progression of dental caries can increase the damage to the tooth structure
and infection likes tooth abscess can occur along with the complete damage to
the tooth structure.
2 Periodontal disease progression can result in loss of tooth and finally to
bones. As a result teeth shifting, bleeding and gum sensitivity are caused.
3 Plaque is mass of bacteria which accumulate and grow on surface within
mouth and surrounding regions of teeth.
4
The injury caused to body tissues due to heat, infection, bacteria or any other
cause damage cells by releasing certain chemicals. These events are known as
inflammatory processes.

Substance misuse.
Sugar in diet.
It can result in growth of harmful bacteria by digesting sugar and if left untreated can
result in cavity and can weaken tooth enamel.
Acid content in diet (include both fizzy and non-fizzy drinks)
Acid content in diet like fizzy drinks and non-fizzy drinks can damage teeth
particularly in children whose tooth enamel are not fully developed.
Smoking.
On of the major effects of smoking on teeth is that it results in the staining of teeth
and also results in the foul smell and can also lead to infected gums.
Alcohol.
Excess alcohol can lead to tooth decay, increase in plaque and can also result in the
oral cancer which is the second most common risk factor of Alcohol.
Substance misuse.
Substance misuse can cause have negative impact on oral health, it can increase

Systematic fluoride is a fluoride which is ingested in water or supplements in
order to maintain oral health.
Advantage: It can make teeth white and shiny.
Disadvantage: It can increase dental caries in a person.
2 Topical fluoride is a fluoride which is applied directly on teeth particular for
children.
Social factors can have a strong impact on social health as children can learn
how to take care of their oral health like brushing teeth twice a day which come
from family ground. Also, any person can start smoking which by getting
influenced by its peers can have negative impact on oral health.
Verbal communication includes sounds tone of voice and pitch are the ways of
communicating verbally. Non-verbal communication includes facial expression,
body language timing, touch or anything else which is done without speaking.
Oral hygiene can be communicated through graphs, videotapes, one to one
instructions, Power Point presentations, leaflets, etc.

effective choice. For the severe cases surgery can also be performed.
Dental caries can be prevented by measures such as pit and fissure sealants, oral
hygiene measures, application of fluoride, using xylitol and by using dental
caries vaccines.
For the preparation and restoration of cavities amalgam and gold knives are
used. It also uses fillings, bridges and capping so that cavities can be finished.
Immediate dentures are inserted immediately after tooth extraction and promotes
healing of gums. These are also called complete dentures. On the other hand
partial denture replaces teeth connected to gum colored plastic base.

Intra ligamentary is peridontal ligament injection which is used for either
infiltration or for obtaining primary anesthesia. It uses stainless steel
intraligamentary syringe.

Explain the role of the Dental Nurse in the clinical monitoring of a patient during treatment to
include:
Skin tone
Breathing
Body language.
During the root canal process x ray is used thus it can have risk of radiation risk if
care if not taken. It also include risk such as discoloration of the tooth and refection
after the procedure.
Disadvantage of root canal procedure is that treated tooth may not have strength as
the original tooth and there are chances of reinfection.
During root canal treatment pulp and nerve are removed so that interior of tooth can
be cleaned.
After the root canal surgery tooth may not heal and there may be higher risk of
infections. In addition during the treatment coronal leakage must be avoided so that
treatment can be successfully done.
Non-surgical endodontic treatments uses biologically acceptable mechanical and
chemical means for promoting the repairing and healing of periradicular tissues.
As compared to other dental methods non-surgical endodontic methods are not
suitable for curved or the narrow canals. Along with this the method is also inefficient
in detection of complicated canal anatomy. After endodontic treatments crown
technique, bridge or other restoration methods are also delayed.
