Q

How to manage AI?

A

OHI
Manage sensitivity: F- varnish, tooth mousse, mouth guards to hold desensitising agents

Q

Clinical considerations in DI?

A
  1. Discolouration - masking w/ restorative materials
  2. Relying dentine bonding - reduced bond strength resin composites
  3. Bone modelling abnomrka - issue providing ortho

25
Prevalence of talon cusp?
Uncommon More prevalent in some racial groups - North Indian population More common in males 2:1
26
What dentition is more common to see talon cusp?
3x more likely in permanent dentition
27
Most frequently affected tooth w/ talon cusp?
Maxillary Lateral incisor
28
Aetiology of talon cusp/ dens evaginates?
Multifactorial - polygenetic and environmental = disturbance tooth formation Familial association
29
When more likely to see dens evaginates?
Pt w/ consanguineous parents Some syndromes Those other dental anomalies
30
What syndromes are more likely to see dens envaginatus?
Ellis-van creveld | Struge-weber
31
What clinical problems are associated w/ talon cusp?
``` Occlusal interference Caries Poor aesthetic Tongue irritation If attrition/fracutee - pulpal exposure ```
32
Do all talon cusps have plural extensions?
Some do and some don't Large talon cusps projecting away tooth surface are most likely to contain plural tissue Radiographs don't help
33
Issue w/ cusp reduction in talon cusp? How to?
Pulpal exposure | Can gradually reduce cusp and allow reparative dentine formation/ plural recession
34
What interval should talon cusp be reduced?
4 weeks, 6 weeks, 8 weeks and 4 months Remove 1-1.5mm tooth each time Place F- varnish each time
35
What tooth does dens dente often affect?
Lateral incisors - more common if conical
36
Mild form of dens dente?
Deep cingulum pit
37
Issue w/ dens dente?
Often involve malformation of pulp - pulp exposure very easily
38
Difference between fusion nd germination?
Fusion - two teeth joined | Germination - single tooth germ divided
39
What do pt often complain w/ double teeth?
Poor aesthetic as wide
40
What is essential before providing tx of double teeth?
Radiograph - need assess root morphology (can share root/pulp)
41
How tx double teeth?
Multidisciplinary approach
42
Why can teeth become discoloured?
``` Tetracycline staining Enamel defects = opacities Congenital herpetic disorder Non-vital teeth DI Caries ```
43
What q's should consider if tooth discoloured?
Is this intrinsic or extrinsic staining | Is this anomaly of tooth development?
44
What colour would teeth be if pt had herpetic disorder?
Green
45
General management of discolouration?
Bleaching Microabrasion Resin infiltration - ICON Veneers
46
When is microabrasion used?
Often first line of treatment for superficial intrinsic enamel staining
47
Difference between mild, moderate and severe Hypodontia?
Mild - less 2 Moderate - 3-5 Severe >6 Excludes 8s!
48
What is associated w/ hyperdontia?
Cleidocranial dysostosis
49
What issues can be associated w/ Hypodontia?
Poor aesthetic Compromised function Loss vertical dimension
50
Why is VD lost in hypodontia pt?
No teeth to maintain alveolus
51
Management of hypodontia?
Multidisciplinary - ortho, paeds and restorative | Vital maintain dentition
52
Tx options for hypodontia|?
Ortho management of spacing Partial dentures- useful mixed dentition Adhesive dentistry - RBB Implants
53
What condition can be associated w/ hypodontia?
Ectodermal dysplasia
54
What features can see in ectodermal dysplasia?
Sparse, thin hair Dry skin Missing teeth Nails deficient
55
Issues associated w/ hyperdontia?
Poor aesthetics Malocclusion - impede tooth eruption Pathology associated unerupted teeth
56
What pathology can be seen in hyperdontia?
Resorption adjacent teeth | Follicular changes
57
Examples abnormalities in tooth eruption?
Infraocclusion Primary failure Ectopic or failure eruption
58
What see infra occlusion?
Teeth appear be sinking below contact point
59
Principles of management of infra-occluded teeth?
Early dx w/ regular review Ortho opinion is successor absent Space maintenance if necessary Early XLA avoid surgery due ankylosis
60
What tooth often has ectopic eruption?
First permanent molar
