Flashcards in Caries in Primary Dentition Deck (21):
What is the definition of early childhood caries?
-ONe or more decayed, missing due to caries or filled tooth surface in any primary tooth under the age of 6.
*decayed may be cavitated or non-cavitated in this case
What is the definition of severe early child hood caries.
As with early child hood caries in 0-3 years old
As with ECC but in primary mx anterior teeth between 3-5 years old
-DMF score equal or greater than 4 (age 3)
-DMF score equal or greater than 5 (age 4)
-DMF score equal or greater than 6 (age 5)
What percentage of of 6 year old Australian children are affected by ECC?
-51% (49% caries free)
What is SiC30, SiC20, SiC10?
Respectively, mean DMFT of the 30%, 20%, 10% of children with highest DMFT scores.
T or F? Caries is transmittable?
-Vertical: to a degree can inherit microbes from parents especially mother
-Horizontal: e.g. kids licking things, sucking on things in childcare centre: kids in childcare centre shown to have similar bacteria.
T or F?
Early exposure to MS increases risk of caries in children? What implications can this carry?
Reducing MS load in mother's mouth during pregnancy can potentially decrease caries risk
What are some risk predictors of a child developing caries?
-Previous caries experience (note that the reverse does not apply; absence of dental caries is not a useful risk predictor for very young children)
-Visible plaque (again reverse does not apply)-->put on at LEAST moderate risk straight away even if no holes
-Dietary factors: bottle in over night leads to pool of fermentable liquid building up initiating decay process, sipping on bottle throughout the day other than if bottle contains water, snacks throughout day (even if not sugary)
Enamel Defects: rough/hypomin areas are at increased risk
Medical conditions: sugar based meds (rarer nowadays), dry mouth, feeding difficulties , (parents may respond by sending them to bed with bottle of milk), poor oral clearance of food due to undeveloped musculature
Siblings with caries
What should you do if perm 6's are present in a child's mouth where decay is present?
Fissure seal straight away
Which area of the mouth is more prone to acid attack and why?
Upper primary incisors (saliva deficiet) therefore if left bottle overnight milk can accumulate a lot more and less buffering
This is followed by distal of first deciduous molars and labial of canines
T/F We should counsel mother on breastfeeding if child has caries and not using bottle?
We should not talk about breastfeeding unless we have received additional training to do so. Instead, look at other dietary factors
Why do we treat primary teeth?
-May affect adult teeth due to abscess development-->pressure cause malposition, can become hypomineralised or hypoplastic
-Load of MS can affect adult teeth when they come through
What are the two main patterns of caries spread in 6 year olds? HOw are each caused?
A's B's, distal of the D's (due to early feeding patterns e.g. bottle overnight). This is also more prevalent in younger children
D's E's affected; A's B's fine: sugary diet but were not given bottle overnight when younger
What area has the lowest chance of being affected by caries?
Lower incisors: sublingual salivary gland
How rapidly can caries in deciduous teeth progress? What are the implications?
Can progress from enamel to pulp in 4 months
-Do not just put duraphat on incipient lesions and send them off as a low risk
-Education about diet, put in fluoride varnish everywhere
-Sometimes need to treat more aggressively
What factors allow caries to progress more rapidly in deciduous teeth?
-Larger dentine tubules
-Larger pulp chamber/pulp horns
What should you consider if you detect upper anterior caries but you can not take bitewings e.g. young child?
-Refer for GA and review every 3 months
Why are labial of canines thought to be susceptible to caries?
-Morphology has a bulge
-Thought that pressure above bulge will cause hypomin-->increase susceptibility
What are the implications of a full mouth clearance?
-Complete loss of space when 5's come through (as 6's drift forward and anterior teeth drift backward)
-However in some cases of severe ECC there is really no other option (e.g. if every tooth is alredy a root stump)
What are some consequences of leaving ECC untreated?
-Harm to permanent dentition (when they come through + affect developing germ)
-Disruption to quality of life/growth and development/loss of self esteem
-Higher incidence of hospitalisation and emergency visits
-Increased treatment costs and treatment time
-Greater risk of new carious lesions
-Cost taxpayer money (one of most common reasons kids have to be treated in hospital)
-Parents need to take time off work
When should a child first see a dentist?
-6 months after tooth first erupts
-No later than 12 months of age
