1. Explain why dental materials and medicament bottles should be stored in the clean zone of
the treatment room and not left on the bench top of the working area.
For easy accessibility during procedures. During treatment procedures time and accuracy is
of essence and therefore, the working area should only have necessary materials and
medications so that specific items are accessed as at and when required. The dental
materials and medications used in a treatment procedure should also be stored in the clean
zone to make it easy for the dental assistant to update notes, radiographs and patients
records that may be on computer system that is usually found on the benches in the clean
zone.
To provide better space for managing client by operator and dental assistant. The storage of
the dental materials and medications in the clean zone and not on the working area helps to
create an ample space for managing the client by the operation and dental assistant during
the treatment procedure.
To avoid contamination of items or drugs. Storage of dental materials at the clean zone and
not on the bench of working areas helps to avoid contamination of other materials or drugs.
2. What are the advantages of using pre-set dental trays and cassettes?
Pre-set dental trays and cassettes are important in organizing instruments for dental
procedures. They also help to organize instruments in an orderly manner in the right
sequence that is most appropriate during procedures. The pre-set systems have standard

Knowledge Questions v1.3 (2017/09/06)
colours that are coded to enhance easy identification, for instance a pre-set system of trays
for maxillary extraction procedure. The also keep instruments organized in sets during
treatment and their organization facilitates their transportation. The order of arrangement
in the pre-set system enables easy maintenance and reprocessing because the entire
cassette can undergo ultrasonic cleaner and sterilization unit. It also reduces the risk of
injury during the process of sterilization and cleaning. The pre-set system and cassette is
also beneficial because it prevents unnecessary loss of equipment that can easily be
misplaced if it handled separately. The pre-set dental trays and cassettes also saves time
during treatment because the assistant can easily reach to the equipment when requested
without taking a lot of time.
3. What is your understanding of the FDI World Dental Federation numbering system and its
benefits?
The FDI World Dental Federation numbering system is an international standard that adopts
two digits to ascertain the location of a tooth by use of quadrant and distance from the mid-
line. The dental numbering system groups teeth into two classes namely permanent
dentition and deciduous dentition. Under permanent dentition, the mouth is sectioned into
quadrants numbered in the clockwise direction from 1 to 4 beginning from the upper-left of
the operators view. The numbering of permanent teeth is done from 1 to 8 commencing
from the central incisors, canines, and premolars moving to the third molar. Under
deciduous dentition, the mouth is sectioned into quadrants counted from 5 to 8 clockwise,
beginning from the upper-right. In baby deciduous, the numbering is done from 1 to 5
beginning at the central incisor and canines to the premolars. The FDI dentition system
helps to avert errors when making a distinction between the sides of the mouth and dental
arches. It’s also beneficial since it can be incorporated into computer languages, thus
making the dentition work more effective.
4. The Australian Schedule of Dental Services and Glossary details standard dental treatments
and assigns a three-digit code number to items and clinical procedures. List at least five items or
services delivered and their three-digit code numbers.
Diagnostic services 001-091
Preventive, prophylactic, and Bleaching services 111-171
Periodontics 213-247
Oral surgery 311 – 399
Endodontics 411- 458
Restorative services 511 to 597
Prosthodontics 611 - 779
Orthodontics 811 – 881
General services 911 -972
Miscellaneous 981 - 999
5. Explain the personal protective equipment you routinely use in the dental surgery and any
standards of PPE that must be met.
Gloves- the gloves help minimize the contamination risk of the puncture wound. However,
it doesn’t prevent sharp injuries. Gloves are used once and are put on at the
commencement of treatment and removed at the end of the procedure. The examination
gloves should comply with AS/NZS 4011 and surgical gloves must comply with AS/NZS 4179

such as the use of sterile gloves in invasive surgery.
Eyewear – Goggles or visors are won in all dental treatment forms or during manual
cleaning of instruments. The eye protection wear protects the eyes against foreign objects
like amalgam fragment and against splatter. Visors are much preferred to spectacles and
loupes because they provide sufficient eye protection due to its additional feature of side
protection. The surgical face masks must comply with AS 4381 mentioned before.
Gowns and aprons – the aprons should be water proof and not permeable to body fluids,
and compliant with AS 3789.2 and AS 3789.3. In cases of exposure to blood or saliva such as
during aerosol generating procedures, then water proof plastic apron are won
6. Why is dietary education important for infants and babies, children and young adults, and
the elderly?
Dietary education is significant for all age groups such as infants and babies, children and
young adults, and the elderly because there is a direct association between diet and dental
caries. The risk factors for dental caries in infants and babies include high intake of fat and
sugar. Additionally, the development of paediatric caries in children aged below five years is
closely linked with the maternal weight and high intake of fat and sugar by expectant
mothers during pregnancy. Thus dietary education in young adults is also important in
preventing dental caries. Additionally, dietary education should be offered to the elderly
adults because research shows that the incidence of carries increased with the increase in
age. The serious loss of teeth in old adults has been attributed to compromise in the quality
of diet. The increase in the sugar content in the diet of the elderly persons increases their
risk of dental carries due to the reduction in saliva levels leaving the root surfaces more
exposed

12. Abrasive burs are used for different purposes. Consider the diagram below, and explain the
uses of the three main types of abrasive burs shown.
Abrasive discs are made up of sandpaper, stone/diamond, or carborundum. They are used
to polish and smooth restorations and appliances.
Abrasive stones are normally used for cutting, completing amalgam restorations and for
cutting. Additionally, they can be used in the laboratory to fine-tune and polish appliances
Rubber wheels and points are majorly used for finishing and polishing without causing
vibrations. They are impregnated with high-density diamond agents to produce a superior
polishing surface and ultra-sharp cutting edge.
