Q

What are the main functions of saliva?

A
  • dilution and clearance
  • neutralisation and buffering
17
Q

What does saliva form on teeth?

A

acquired pellicle formation

18
Q

What elements does saliva control for remineralisation?

A

calcium, phosphate and fluoride

19
Q

What can dental occlusion influence?

A

abfraction and cervical area becomes more susceptible to erosion

20
Q

In relation to soft tissue anatomy, where is the most severe area of erosion found?

A

palatal surfaces of teeth that are touched by the tongue

21
Q

What does the tongue influence?

A

areas that acid contacts and clearance patterns

22
Q

Why is history taking important?

A

may find aetiology and assist in lifestyle changes, leading to prevention of further erosion

23
Q

What should be recorded in a diet diary?

A
  • weekday/ weekend
  • what and when
24
Q

What oral hygeine advice may be given to normal patients?

A

  • avoid brushing following acids
  • sugar free gum
25
Q

What percent of fluoride rinse should be used?

A

0.025-0.5% non-acidulated fluoride

26
Q

What oral hygiene advice would be given to patients with erosion?

A
  • decrease frequency of acid foods/ drinks
  • acid foods only at mealtimes
  • finish meal with neutral food e.g., cheese
  • drink acid beverages quickly
  • rinse with water after acid consumption
27
Q

What are the first 2 prevention interventions?

A
  • early diagnosis and monitoring
  • information and instruction
28
Q

What are 3 prevention techniques of erosion?

A
  • professional stain removal
  • fluoride application (4 yearly)
  • replacement of failed occlusal restorations
29
Q

What is essential before any type of operative intervention?

Basic Erosive Wear Examination

31
Q

What are ways to make space for restorations?

A

The Dahl Appliance

32
Q

What does the Dahl Appliance consist of?

a removable Co/Cr splint with 2mm coverage of palatal surfaces of upper anteriors and buccal retention on canines and premolars

33
Q

What have studies shown about the Dahl Appliance?
