smoking

what is very brief advice?

  • Ask
    -Advise
  • Act
    smoking cessation.
128
Q

why is it important for dental professionals to carry out very brief advice?

A
  • smoking is a secondary risk factor for smoking
  • smoking will modify how perio tissues respond to plaque
  • smoking reduces saliva flow

Q

what are some of the effects of smoking on the oral cavity?

A
  • melanin
  • fibrotic gingiva

what is the golden ratio in denistry?

A

1:6

131

A

proximal carious lesions.

132
Q

what is transillumination? and why would it be used?

A
  • shinning light through contact points, to assist with diagnosis of approximal caries.
  • dark= caries.
133
Q

describe an active carious lesion

A

progressive
orange/brown
soft

134
Q

describe an arrested or inactive carious lesion

A

formed earlier then stopped
dark brown/black
hard
leathery

135
Q

what does ICDAS stand for?

A

international caries detection and assessment system.

136
Q

what probes are used for a clinical examination? and why?

A

ball-ended - this is so it will not cause any damage to potential white spot lesions.

137
Q

With ICDAS caries code what is meant by 0?

A

sound tooth surface

138
Q

With ICDAS caries code what is meant by 1?

A

1st visual change in enamel

139
Q

With ICDAS caries code what is meant by 2?

A

distinct visual change in enamel

140
Q

With ICDAS caries code what is meant by 3?

A

enamel breakdown, no dentine visible

141
Q

With ICDAS caries code what is meant by 4?

A

dentinal shadow (not cavitated into dentine)

142
Q

With ICDAS caries code what is meant by 5?

A

distinct cavity with visible dentine

143
Q

With ICDAS caries code what is meant by 6?

A

extensive distinct cavity with visible dentine

144
Q

what is understood by ICDAS caries codes 1-2?

A

initial caries

145
Q

what is understood by ICDAS caries codes 3-4?

A

moderate caries

146
Q

what is understood by ICDAS caries codes 5-6?

A

extensive caries

147
Q

what are the 4 D’s in caries care? Set out by ICDAS

A
1= Determine
2= Detect
3= Decide
4= Do
148
Q

what can cause trauma related gingival recession?

A
  • foreign bodies - piercings
  • nail picking
  • tooth brushing
  • partial dentures ( poor design/ poorly maintained)
  • direct from malocclusion (gingival stripping)
  • chemical trauma (topical cocaine )
149
Q

what is key to recession and gingival inflammation in regards to probable recession?

A

thickness of the keratinised tissue - thin tissue is pre-disposed to recession in presence of plaque-indiced inflammation or trauma.

150
Q

what are the possible consequences of recession?

A
  • fear of tooth loss
  • PRF and bleeding gingiva
  • aesthtics
  • root caries
  • abrasion
151
Q

what type of pain is normally associated with dentine hypersensitivity?

A

short sharp pain

152
Q

does dentine hypersensitivity get worse or better with age and why?

A

better as more dentine is deposited in the tubules preventing fluid flow.

153
Q

what can act as a stimuli for dentine hypersensitivity?

A
  • thermal
  • osmotic (hypertonic solutions eg sweet, spicy, acid)
  • desiccation (drying of lesion)
  • electric (galvanic reactions and electric pulp test)
  • tactile (touching, probing, TB)
154
Q

what is the hydrodynamic mechanism?

A

dentine hypersensitivity caused by the movement of dentinal tubules content increased outward fluid flow causing a pressure change across the dentine.

155
Q

what needs to be recorded in regards to recession?

A
  • record extent of recession
  • description
  • index
  • identify etiological factors
156
Q

How can you manage dentine hypersensitivity?

A
  • Tubule occlusion - application of an artificial barrier eg varnish, fills etc.
157
Q

what is the purpose of tubule occlusion?

A

prevent dentine hypersensitivity.

promotes formation of new tissue

158
Q

what are the ideal qualities of a barrier material for dentine hypersensitivity?

A
  • retentive
  • insoluble
  • penetrate tubules
  • forms mechanical tags into tubules
  • seals the end of the tubules.
159
Q

how can a patient manage dentine hypersensitivity at home?

A
  • TP, gels and mouthwash
160
Q

how can a professional manage dentine hypersensitivity in surgery?

A
  • varnish
  • resin bonding systems
  • desensitising polishing pasta
  • reinforced GIC where there is abrasion cavity progression
161
Q

what advice can you give a patient to aid in the prevention of recession?

A
  • change TB techniques
  • smoking cessation
  • reduce risk factors - acidic drinks/foods, brushing after acid attack, night splint if brixist etc.
162
Q

what is the treatment plan for root caries?

A
  • x-rays to detect interproximal caries
  • prevention, diet and OHI, fluorides.
  • recontouring of shallow lesion
  • GIC restoration
