Q

F varnish works in 3 ways

A

slows down development of carious lesions by stopping demineralisation - SLOWS CARIES PROGRESSION

makes enamel more resistant to acid attack from plaque bacteria and speeds up remineralisation, does so with F so more strong/less soluble - CARIES ARRESTING

stops bacteria metabolism at high concentrations - CARIES INHIBITING

Q

method of application of topical fluoride

A

remove gross plaque

apply sparingly in thin layer - do not need to use all

paint varnish onto dry, isolated teeth with microbrush

91
Q

behaviour management

A

continuum of interaction with a child/pt directed towards communication and education

92
Q

goals of paeds behaviour management

A

ease fear and anxiety

promoting an understanding of the need for good dental health

93
Q

normal childhood development

age 2

A

fear of unexpected movements, loud noises and strangers

dental situation can produce fear in child

94
Q

normal childhood development

age 3

A

reacts favourably to positive comments about clothes and behaviour

less fearful of separation from parents (due to nursery)

experience will dictate reaction to separation

95
Q

normal childhood development

age 4

A

more assertive - bossy/aggressive possible

fear of unknown and bodily harm is now at peak

fear of strangers can be slightly decreased

with firm, kind direction can be excellent pts

96
Q

normal childhood development

age 5

A

readily separated from parents

fears usually diminished

proud of possessions - use to engage and build rapport

comments on clothes - quickly establishes rapport

97
Q

normal childhood development

age 6

A

seeks acceptance

success in acceptance can affect self-esteem

if child develops feeling of inferiority or inadequacy at dentist then behaviour may regress to that of younger age

98
Q

normal childhood development

age 7-12

A

question inconsistencies and conform to rules of society - engage

still have fears bit better at managing them
- ask obvious Qs to see if they can be addressed e.g. why do you dislike the chair? (maybe movement when in, so can move into position prior)

99
Q

when are anxiety, behaviour and compliance linked in development

A

ages 3-8

older children able to use assessment tools MCDAS

100
Q

dental anxiety

A

occurs without a present triggering stimulus and may be a reaction to an unknown danger or anticipatory due to previous negative experiences

101
Q

dental fear

A

normal emotional response to objects or situations perceived as genuinely threatening

102
Q

phobia

A

clinical mental disorder where subjects display persistent and extreme fear of objects or situations with avoidance behaviour and interference in daily life
- avoid going to dentist

103
Q

3 components of dental fear and anxiety

A
  1. physiological and somatic sensations
  2. cognitive features
  3. behavioural reactions
104
Q

physiological and somatic sensations components of DFA

A

breathlessness

perspiration

palpitations

feeling of unease

105
Q

cognitive features of DFA

A

how changes occur in thinking process

  • interference in concentration
  • hypervigilence (swivel heads)
  • inability to remember certain events when anxious (mind racing)
  • imagining worse that could happen
106
Q

behavioural reaction of DFA

A

avoidance i.e. postpone dental app, child disruptive behaviour

escape from situation which precipitates anxiety

anxiety may manifest as aggression - esp adolescents

  • feel not listened to
  • explain will not do anything until we know that they are comfortable and how they are - dentistry is 2nd to them

dentist should always ensure safety of pt and staff

107
Q

Signs of DFA

A

some easy

some subtle

  • time delay asking Qs
  • stomach aches/need to go to toilet
  • headaches, dizziness
  • fidget
  • stutter
  • ‘can’t be bothered’
108
Q

factors that influence DFA

A
fear of choking 
fear of injection/drilling 
fear of unknown 
past medical/dental experience
dental experience of family/friends
attitudes of parents 
preparation at home before appt
child's perception that something is wrong with teeth 

useful to know so can specifically reassure

109
Q

control related measure to assist DFA

A

rest breaks

stop signals

pt need for info

110
Q

MCDAS

A

modified child dental anxiety scale

can get faces version

8+

base line DFA established

111
Q

good dentist/pt communication allows (4)

A

improved information obtained from pt
- more you know the better the Tx as more adapted

enable dentist to communicate information with pt

increases likelihood pt compliance - feel safe, listened to

decrease pt anxiety

112
Q

behavioural management techniques (7)

A

positive reinforcement

tell show do

acclimatisation

voice control

distraction

role modelling

relaxation/hypnosis

113
Q

Building Tx plan for children - general guide

A

simple -> complex

OHI, FS, upper before lower for restorations

114
Q

Paeds Tx plan

A
  1. exam, Fluoirde varnish, diet sheet given, toothbrush to bring on next visit, explain/take radiographs
  2. brush teeth with their brush, invite on chair, check diet, radiographs
    polish teeth and dry (slow speed + air syringe),
    explain FS
  3. FS, introduce saliva injector
  4. remove carious tissue with hand excavator if immediate temporisation needed
    Use slow speed for small buccal and cervical carious lesions
    introduce topical and give rubber dam home
  5. restore uppers with LA (topical then injection)
  6. restore lower teeth with LA
  7. pulp Tx then extractions if pt pain free e.g. if pulpotomy needed, do before extractions
