causes discoloration and damage to tooth enamel. Therefore, 1 ppm is the
recommended level to ensure the right amount of fluoride for dental health.

Remineralized enamel appears:
1) Smooth and shiny
2) Dark, hard, and opaque
3) Soft and chalky
4) Rough and porous
When enamel is remineralized, it can take on a darker, more opaque appearance due to the incorporation of minerals such as calcium and phosphate. While the newly formed mineral deposits can restore some of the tooth's strength and resistance to decay, they do not replicate the original enamel's structure, resulting in a visual change. The appearance of the enamel can vary depending on the extent of the remineralization process and may not always be as smooth and shiny as unaltered enamel.

2) Decreases diffusion of the anaesthetic drug
3) Causes rapid elimination of the local anaesthetic
4) Decreases speed and quality of anaesthesia
The speed of onset of Anaesthesia is raised by Sodium bicarbonate and further enhances its quality by elevating the intensity and duration of block.
Burs used for refinement and finishing of composites:
1) Fine carbide.
2) Diamond.
3) A and B.
4) Discs.
ADC Test Answer: 3
Refinement and finishing of composites often require a combination of both fine carbide and diamond burs, as each serves distinct functions in achieving a polished finish.
Which of the following is NOT a type of dental charting?
- Periapical charting
- Panoramic charting
- Full mouth series charting
- Bitewing charting
Panoramic radiographs are not a type of charting.
What is the primary feature of trigeminal neuralgia?
1) Constant dull pain
2) Intermittent sharp pain triggered by stimuli
3) Pain that worsens at night
4) Pain associated with swelling
Trigeminal neuralgia is characterized by sudden, severe, and sharp facial pain that can be triggered by light touch or other stimuli.
The alpha-2 function pre-synaptically at the neuromuscular junction is
responsible for:
1) Facilitation of transmitter release
2) Inhibition of transmitter release
3) Activation of cholinergic receptors
4) Blockade of sodium channels
Alpha-2 receptors located pre-synaptically can inhibit the release of the neurotransmitter acetylcholine.
What’s the percentage of tooth erosion in 6-year-olds and 15-year-olds in the UK?
1) 5-10% and 15-20%
2) 5-52% and 15-27%
3) 10-30% and 20-40%
4) 15-25% and 25-35%
Studies indicate that tooth erosion affects a significant percentage of children, with varying rates between different age groups.
What is the best method to disinfect a dental bridge before sending it to the lab?
1) Soaking in bleach
2) Autoclaving
3) Using 70% isopropyl alcohol
4) Rinsing with water
70% isopropyl alcohol is effective for disinfecting dental appliances as it kills bacteria and viruses without damaging the material of the bridge.
The muscle assisting in mastication but not supplied by mandibular nerve is tensor veli palatine
The diagnosis for a tooth (75) with deep decay extending to the pulp is likely:
1) Periapical abscess
2) Dentigerous cyst
3) Granuloma
4) Radicular cyst
ADC Test Answer: 2
Deep decay can result in the formation of a dentigerous cyst, especially if associated with an unerupted tooth, reflected in imaging as a radiolucency surrounding the root.
Which of the following may be caused by a newly placed restoration that interferes with the occlusion?
1) Apical abscess
2) Pulpal necrosis
3) Apical periodontitis
4) Periodontal disease
An occlusal interference can lead to increased stress on the tooth, potentially resulting in apical periodontitis.
The essential. sulphur containing amino acid is: 1. Methionine 2. Cystetne 3. Cystine 4. Valine
Biochemistry Answer: 1Methionine is sulphur containing AminoAcid
Ferrite and austenite are soft and ductile
Sickle cell anemia is precipitated when:
1) Oxygen tension goes down
2) Increased viscosity of blood is there
3) There is dehydration
4) All of the above
Sickle cell disease results from mutation, or change, of certain types of hemoglobin chains in red blood cells (the beta hemoglobin chains). When the oxygen concentration in the blood is reduced, the red blood cell assumes the characteristic sickle shape.
Your employer is attempting to update office sterilization procedures; what would you recommend as the BEST method to verify that sterilization has occurred?
1) Use color change tape in each load and spore tests weekly
2) Use indicator strips in each load and color change tape on each package
3) Use indicator strips daily and spore tests weekly
4) Use color change tape daily and spore tests monthly
ADC Test Answer: 3
Color-change tape each load + weekly spore tests – Tape only shows the package was exposed to heat, not that sterilization was achieved. Indicator strips each load + color-change tape each package – No spore testing included → cannot verify sterilization. Indicator strips daily + spore tests weekly – Includes both chemical indicators and weekly spore tests → best match. Color-change tape daily + spore tests monthly – Monthly spore testing is inadequate.
What is the most effective way to prevent the transmission of tuberculosis in the dental setting?
1) Screening patients for TB
2) Vaccinating dental personnel
3) Using N95 respirators
4) All of the above
The most effective way to prevent the transmission of TB in the dental setting involves a combination of strategies, including screening patients for TB, vaccinating dental personnel, and using appropriate respiratory protection, such as N95 respirators, during procedures that may generate aerosols.
What is the GDC's requirement for the storage of patient records?
- They must be kept in a secure, locked cabinet
- They must be kept in a fireproof safe
- They must be kept in a format that is easily accessible and understandable
- They must be kept in a location that is accessible only to the dentist
The GDC requires that patient records be kept in a format that is easily accessible and understandable to ensure that dental professionals can provide effective care based on accurate and up-to-date information.
What is the characteristic radiographic feature of distoangular impaction?
1) The tooth is horizontally positioned
2) The tooth is tilted towards the ramus
3) The tooth is tilted towards the tongue
4) The tooth is completely embedded in the bone
Distoangular impaction occurs when the tooth is tilted towards the ascending ramus of the mandible, making it challenging to remove due to the need for significant bone removal.
