Types of amelogenesis imperfecta
hypoplastic
hypocalcified
hypomaturational
mixed with taurodontism
cause of environmental enamel hypoplasia
systemic
nutritional
metabolic e.g. Rhesus incompatibility, liver disease
infection e.g. measles
cause of localised enamel hypoplasia
trauma
infection of primary tooth
How to treat fluorosis
Microabrasion
Vital bleaching
veneers
prenatal causes of generalized enamel defects
congenital syphilis/cardiac and kidney disease
Fluoride
Thalidomide
neonatal causes of generalized environmental enamel defects
prematurity
meningitis
postnatal causes of generalized enamel defects
chickenpox
measles
otitis media
pneumonia
How to diagnose amelogensis imperfecta
FH
generally affects both dentitions/all teeth
tooth size, structure, colour
radiographs
Gene mutations in amelogenesis imperfecta
enamel extracellular matrix molecules amelogenin, enamelin, kallikrein 4
what is hypoplastic amelogenesis imperfecta
enamel crystals do not grow to correct length
what is hypomineralised/calcified AI
crystallites fail to grow in thickness and width
What is hypomaturational AI
enamel crystals grow incompletely in thickness or width but to normal length with incomplete mineralisation
Problems with AI
anterior open bite
caries
delayed eruption
poor aesthetic/OH
sensitivity
AI Tx
composite veneers/comp wash
fissure sealants
metal onlays
ortho
preventative therapy
SS crowns
3 types of dentinogenesis imperfecta
1- osteogenesis imperfecta
2- autosomal dominant
3- brandywine
what is dentine dysplasia
normal crown morphology
amber radiolucency
pulpal obliteration
short constricted roots
what is odontodysplasia
localised arrest in tooth development
thin layers of enamel and dentine
large pulp chambers
ghost teeth
How to diagnose DI
appearance
associated osteogenesis imperfecta
both dentitions affected
enamel loss
FH
radiography: bulbous crown, pulp obliteration
DI problems
aesthetics
caries
spontaneous abscess
DI solutions
comp veneers
overdentures
prevention
removable pros
SS crowns
hereditary dentine defects limited to dentine only
DI type 2
dentine dysplasia type 1+2
fibrous dysplasia of dentine
hereditary dentine defects associated with general disorder
brachio-skeletal genital syndrome
ehlers-danlos syndrome
hypophosphatasia
osteogenesis imperfecta
rickets
Overview of dental management of tooth defects
continuous dental care
management of growth and development
removable pros
crowns and bridges
interceptive ortho
cementum anomalies: what is cleidocranial dysplasia
hypoplasia of cellular component of cementum
cementum anomalies: what is hypophophatasia
hypoplasia or aplasia of cementum
early loss of primary teeth
Eruption anomalies- premature eruption aetiology
High birth weight
Early puberty
Natal/neonatal teeth
Eruption anomalies- delayed eruption aetiology
Low birth weight
Malnutrition
Downs syndrome
Gingival hyperplasia
Eruption anonalies- premature exfoliation aetiology
Trauma
Following pulpotomy
Hypophosphatasia
Immune deficiency
Eruption anomalies- delayed exfoliation aetiology
Infra-occlusion
Hypodontia
Ectopic successors
Post-trauma
Supernumaries
Early loss/retained primary
Crowding/dilacerated tooth
MIH- pre-natal aetiology
Mother’s general health in 3rd trimester
Ask if pre-eclampsia/gestational diabetes
MIH post-natal aetiology
Childhood infection-chickenpox,measles,rubella
Prolonged breast feeding/SES/medications
MIH problems
Secondaries caries
Aesthetics/sensitivity
Toothwear
Discolouration
MIH management of molars
Restorations
Consider XLA
SSC
MIH- management of incisors
Microabrasion
Resin infiltration
Composite buildup
Composite veneers
Why is MIH sensitive
Increased nerve and increased vascularity and increased immune cells
What is MIH
Enamel hypomineralisation of systemic origin of first permanent molars, and frequently associated with incisors
When can u extract 1st permanent molar
Pt between 8-10
Bifurcation of 7s
Calcification of 8s
