  • Distance from the pulp
  • Number of odontoblasts cut
  • Strength of the stimulus

Question 3

Answer
  • True
  • False

Question 5

Question
Procedures designed to remove the smear layer for bonding also increase the resistance of dentine to chemical / bacterial toxins.
Answer
  • True
  • False

Question 6

Question
Filling material can be problematic to the oral tissues because it can cause: [blank_start]Chemical[blank_end] irritation to the pulp [blank_start]Heat[blank_end] transfer to the pulp [blank_start]Galvanic[blank_end] current to be set up
Answer
  • Chemical
  • Heat
  • Galvanic

Question 7

Question
Filling techniques can be a problem for the oral tissues because: [blank_start]Matrix bands[blank_end] can injure the gingiva Poor restoration margins can lead to [blank_start]recurrent[blank_end] caries Poor occlusal relationship can lead to apical pressure and [blank_start]apical periodontitis[blank_end]
Answer
  • Matrix bands
  • recurrent
  • apical periodontitis

Answer
  • periapical
  • bacteria

Question 10

Question
In terms of impression taking, these factors could affect the oral tissues: Too fluid material = [blank_start]respiratory[blank_end] problems Exothermic material (such as impression [blank_start]compound[blank_end]) can cause [blank_start]burns[blank_end] Wrong size tray = [blank_start]mucosal[blank_end] injuries
Answer
  • respiratory
  • burns
  • compound

Answer
  • Fibroepithelial hyperplasia

Question 12

Question
When taking biopsys the following factors should be considered: Avoid taking biopsies of [blank_start]vascular[blank_end] lesions Make sure the sample is [blank_start]representative[blank_end] Include normal tissue as a [blank_start]control[blank_end] Avoid [blank_start]distortion[blank_end] of tissues If the patient has no confidence in the practitioner If the patient is in [blank_start]pain[blank_end] If the lesion is large but [blank_start]benign[blank_end] If it is not accessible at the time If there is [blank_start]infection[blank_end] at the site If there is uncontrolled [blank_start]systemic[blank_end] disease
Answer
  • vascular
  • representative
  • control
  • distortion
  • pain
  • benign
  • infection
  • systemic

Question 13

Question
In terms of different types of biopsies: Excisional = [blank_start]removal[blank_end] of tissue Incisional = p[blank_start]artial[blank_end] removal of tissue Extemporary = in t[blank_start]heatre[blank_end] Exfoliative = [blank_start]smear[blank_end] tests Fine needle aspiration = if in[blank_start]accessible[blank_end] via scalpel such as in the [blank_start]salivary[blank_end] glands
Answer
  • removal
  • artial
  • heatre
  • smear
  • salivary
  • accessible
