Child Dental Health Flashcards
What does ART stand for?
Atraumatic Restorative Treatment
When does ART consist of?
Interventive approach that involves selective caries removal using hand instruments and placement of glass ionomer
What is the purpose of using separator bands?
They are useful to open proximal contacts and create space - aids caries diagnosis
What is silver diamine fluoride used for?
manages and prevents dental caries, as well as relieving dentinal hypersensitivity
What is the reason for having silver in fluoride varnish?
possesses antimicrobial properties
What is the reason for using fluoride to arrest dental caries?
remineralises enamel and dentine
What is used alongside SDF to minimise staining?
potassium iodide capsules
What is the Hall Technique?
A method of “sealing in” caries within a primary molar. A stainless steal crown is placed over primary teeth with no caries removal, tooth prep or use of local anaesthetic
What is a Pulpotomy?
a less invasive procedure where the pulp that resides in the main part (or crown) of the tooth is taken out, but the roots are left in
What is the checklist to use when checking for dental anomalies?
Quantity
Size and form
Formation
Structure
What is hypodontia?
Missing teeth as a result of them failing to develop
What are the 2 types of hypodontia?
Anodontia
Oligodontia
What is anodontia?
total lack of teeth in one or both dentitions
What is oligodontia?
Rare condition where more than 6 primary or permanent teeth are absent
What causes hypodontia?
Likely to be genetic - mutations in the MSX1 gene on chromosome 4
Occasionally environmental insult
Sometimes linked to single gene disorders
Can be associated with certain syndromes - down syndrome
What are supernumerary teeth?
the existence excessive number of teeth in relation to the normal dental formula.
What are the types of supernumeraries?
Mesiodens
Supplemental teeth
Conical supernumeraries
Tuberculate supernumeraries
What are mesiodens?
in the midline:usually peg shaped teeth
What are supplemental teeth?
Look like a normal tooth
What are conical supernumeraries?
a small peg-shaped tooth, the most common supernumerary found in the permanent dentition and it usually presents between the maxillary central incisors
What are tuberculate supernumeraries?
have got more than one cusps or tubercle on their crown.
What is the difference between tuberculate and conical supernumerary teeth?
The conical supernumerary can result in rotation or displacement of the permanent incisor, but rarely delays eruption. The tuberculate type of supernumerary possesses more than one cusp or tubercle. It is frequently described as barrel-shaped and may be invaginated.
Is microdontia more common in males or females?
females
What teeth are most affected by microdontia?
Lateral incisors
What is macrodontia?
Double teeth - a dental condition where a tooth or group of teeth are abnormally larger than average
Double teeth - fusion - what does this mean?
Abnormal shaped tooth resulting from fusion of 2 separate tooth germs
Double teeth - germination - what does this mean?
2 teeth develop from 1 tooth germ
What is dens in dente?
A tooth within a tooth
What is a talon cusp?
an extra cusp on an anterior tooth which arises as a result of evagination
What is amelogenesis imperfecta?
a disorder that affects the structure and appearance of the enamel of the teeth. This condition causes teeth to be very small, discolored, pitted or grooved, and prone to rapid wear and breakage with early tooth decay and loss.
What are the 2 classes of amelogenesis imperfecta?
Hypoplastic
Hypomineralised
What is dentinogenesis imperfecta?
causes the teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent. Teeth are also weaker than normal, making them prone to rapid wear, breakage, and loss.
What does MIH stand for?
Molar Incisor Hypomineralisation
What is Molar Incisor Hypomineralisation
Developmental defect in enamel structure, only effects 1s, 2s and 6s
What is fluorosis?
a condition that causes changes in the appearance of tooth enamel due to overexposure of fluoride during amelogenesis
what is turner’s tooth?
An enamel defect in the permanent teeth caused by periapical inflammatory disease in the overlying primary tooth
What is a dilacerated tooth?
If the crown (top) or root of a tooth has an irregular bend
What is an example of a metabolic disturbance effecting the dentition?
haemolytic bilirubin anaemia
A malfunction in which tooth development stage causes anodontia?
initiation stage
A malfunction in which tooth development stage causes supernumerary teeth?
initiation stage
A malfunction in which tooth development stage causes microdontia/macrodontia?
Bud stage
A malfunction in which tooth development stage causes dens in dente?
cap stage
A malfunction in which tooth development stage causes fusion and germination
cap stage
When do primary teeth start to erupt?
6 months
Which teeth erupt first?
Lower central incisors
When is the primary dentition complete?
30 months (2 1/2 yrs)
When does the mixed dentition stage begin?
6 yrs old
What teeth are the first to erupt in the permanent dentition?
lower centrals
What are the 2 main phases of the mixed dentition stage?
between 6-8 yrs old
between 10-12 yrs old
When is the permanent dentition established?
Around 12 yrs
What are the main features of the established permanent dentition?
Molar relationship
No crowding
No spacing
No rotated teeth
Occlusal plane flat or mild curve of spee
At what age should canines be palpable?
9 yrs old
What is the curve of spee?
The curvature of the mandibular occlusal plane
Why is there a lot of spacing in the primary dentition?
To allow space for the permanent dentition as it has more teeth
What habits can effect the dentiton?
The use of dummies and thumb sucking
What can happen if there is an early loss of primary teeth?
Fibrous tissue can form over the erupting tooth delaying its eruption, unless the permanent tooth has 1/3 to 2/3 of the root formation completed then there will be accelerated eruption
Explain class 1 incisor relationship
The lower incisor edges occlude with the upper central incisor central plateaus
Explain class 2 division 1 incisor relationship
The lower central incisor edges sit posteriorly relative to the upper central incisor central plateaus
The upper central incisors are proclined
often an increased overjet
Explain class 2 division 2 incisor relationship
The lower central incisor edges sit posteriorly relative to the upper central incisor central plateaus
The upper central incisors are retroclined
Often a minimal overjet
Explain class 3 incisor relationship
The lower central incisor edges sit anteriorly relative to the upper central incisor central plateaus
overjet is reduced or reversed
What classification is relevant to molar relationships?
Angle’s classification
Explain class I molar relationship
mesio-buccal cusp sits in the buccal groove
Explain class II molar relationship
disto-buccal cusp is sitting in the buccal groove
Explain class III molar relationship
mesio-buccal cusp has jumped a whole cusp backwards
What is a class II mandible?
where the lower first molar is posterior (or more towards the back of the mouth) than the upper first molar
What is a class III mandible?
where the lower first molar is anterior (or more towards the front of the mouth) than the upper first molar.
