“A dietary CHO-modified infectious disease in
which saliva is a regulating factor”



Most common chronic infectious disease in
childhood
5x as common as asthma
Is a disease process
The presence of 1 or more decayed, missing or
filled tooth surfaces in any primary tooth in a
child under the age of 6.
1. Microbiology
◦
◦
◦
◦
1683 van Leeuwenhoek observes microorganisms
1890 W.D. Miller, “non-specific plaque theory”
1924 Clarke, isolates streptococcus mutans
1960 Keyes, specific microorganisms cause caries
and are transmissible

MS (mutans streptococcus)
◦ Ecological niche in human oral cavity
 Acidogenicity, aciduricity and adherence to teeth
 Metabolizes variety of sugars
 Responsible for initiation of caries, not sole factor

MS acquisition by infants
◦ Oral cavity colonized after eruption of teeth
◦ Window of infectivity
◦ Mostly acquired between 19-33 mths of age
 Those who acquire early may be at ↑ caries risk

Transmission
◦ direct or indirect
◦ Vertical, usually from mother

Colonization
◦ +: sweet fluids, sugar exposure, snacking, food
sharing
◦ -: toothbrushing, multiple courses of abx
2. Dietary Factors
◦ Food factors that are protective
 Milk: calcium, phosphate, casein, protease peptones
 Cheese: similar to milk, ↑ saliva
 Apples, cranberries: flavonoids, inhibit bact adherence,
antibact action
 High fiber foods: mechanical stimulation of salivary
flow
Healthiest alternative:
whole foods, non-processed foods
3. Host Factors:
◦ Tooth Factors
 Enamel quality, pits & fissures, hypoplasia, Fl exposure
◦ Saliva
 mineral content, pH, flowrate, buffering capacity,
antimicrobial components, Fl, supersaturated with Ca
and P, proteins, immunologic components
 Flow rate
 ↓ by meds, disease, dehydration, radiation, age
 ↑ by gustatory and masticatory stimulants
4. Modifying Factors
◦
◦
◦
◦
◦
◦
◦
◦
◦
Race/ethnicity
Healthcare delivery system
Socioeconomic status
Behaviour/education
General health
Culture
Stress
Genetic factors
Other

Shifts in Presentation
◦ 19th vs 20th/21st centuries
 19th century: disease of affluence
 20th/21st centuries: disease of poverty
◦ 1900-1950: pandemic
◦ 1950-1970s: era of fluoridation
◦ 1970s-present: decline in caries prevalence
 shifts in ethnic/SES distribution
 80% caries in 20-25% population

Primary Teeth: dx and tx considerations
◦
◦
◦
◦
More rapid progression of caries
Enamel and dentin thinner
Pulp relatively larger
Flat contacts
◦ Caries sequence
 Mand molars → Max molars → Max anteriors

Principles:
◦ Reorient: tx of cavities (disease) → mgmt of caries (process)
◦ Surgical approach problematic
◦ Treat cause than manifestation of disease

Strategy:
◦ Determine child’s current caries experience
◦ Estimate risk for future caries
◦ Develop plan to address current problem and
prevent future disease

Why: health supervision, not disease tx

Old Model:
◦ Caries inevitable
treat effects → preventive care → start age 3

New Model:
examine early → risk assessment → anticipatory
guidance → true prevention

AAP, ADA, AAPHD:
◦ support initial evaluation by age 1

AAP Policy Statement:
◦ Identify high-risk children at an early age
◦ Identify high-risk mothers during pregnancy
◦ Use anticipatory guidance, behaviour modification
(OH, feeding practices)
◦ Establish dental home by age 1 year

AAP recommends referral to dentist by age 1
◦
◦
◦
◦

Child has special health care needs
Mother has high caries rate
Child has caries, plaque, demin and/or staining
Family is low SES
Anticipatory Guidance
◦ Practical, dvlpt-appropriate health info
◦ Alert impending change, teach role in maximizing
child’s dvlpt potential, identify child’s special needs

Concept of Dental Home
◦ Modeled after AAP medical home
◦ Philosophy embraced by dental practice
◦ Characteristics:
 Accessible, family-centered
 Comprehensive, coordinated, continuous
 Compassionate, culturally competent
 Embraces prevention
 Coordinates specialized care
 Provides personalized recall program and emerg care
Risk Assessment
1. Tx disease process than outcome of disease
2. Understanding of disease factors & aids in
individualizing preventive discussions
3. Individualizes, selects & determines frequency of
preventive and restorative tx
4. Anticipates caries progression/stabilization

CRA is the determination of:
the likelihood of the incidence of caries during
a certain time period
or
the likelihood that there will be a change in the
size or activity of lesions already present.

Caries risk indicators are variables
◦ thought to cause disease directly
◦ shown useful in predicting disease
◦ considered protective factors
Best tool to predict future caries is past caries
experience



Children with white spot lesions should be
considered at high risk for caries
Plaque accumulation is strongly associated
with caries development
MS levels and age at which child becomes
colonized with cariogenic flora
Factors
High Risk
Mother/primary caregiver has
active cavities
Yes
Parent/ caregiver has low
socioeconomic status
Yes
Child has >3 between meal
sugar-containing
snacks/beverages per day
Yes
Child is put to bed with a bottle
containing natural or added
sugar
Yes
Moderate Risk
Child has special healthcare
needs
Yes
Child is a recent immigrant
Yes
Protective
Factors
High Risk
Moderate Risk
Protective
Child receives optimallyfluoridated drinking water or
fluoride supplement
Yes
Child has teeth brushed daily
with fluoridated toothpaste
Yes
Child receives topical fluoride
from health professional
Yes


CRA Tool can:
◦ Aid in identification of reliable predictors to identify
and refer high-risk children
◦ Assist in providing evidence for and justifying:
 periodicity of service
 modification of third-party involvement in the delivery
of dental services
 quality of care with outcomes assessment to address
limited resources and workforce issues

Designed to assist in clinical decision-making
Provide criteria regarding dx and tx
Lead to recommended courses of action

Result:


◦ aids in developing an individualized treatment plan
◦ based on specific patient’s risk levels, age and
compliance
◦ incorporates preventive strategies

Caries management:
◦ Past: caries a progressive disease that eventually
destroyed tooth unless surgical/restorative
intervention
◦ Now: known surgical intervention alone does not
stop disease
 modern management more conservative and
individualized
1. Determine risk category
a.
b.
c.
d.
e.
Low risk
Moderate risk – parent engaged
Moderate risk – parent not engaged
High risk – parent engaged
High risk – parent not engaged
2. Diagnostics: recall schedule, rads, MS levels
3. Interventions: Fl, diet, sealants
4. Restorative: surveillance incipient, restore
cavitated lesions

Dental CRA, based on child’s age, biological
factors, protective factors and clinical findings
should be part of new & periodic examinations
Estimating caries risk will help establish
periodicity and intensity of diagnostic,
preventive and restorative services
Clinical management protocols will enable
individualized patient management of dental
caries
