Caries-risk Assessment and Management for Infants, Children, and Adolescents

Board takeaway

• Treat disease and lesions. Restorations alone do not control caries; many lesions stabilize, and restorations have limited longevity.
• Assess from the age-one visit onward. Repeat at new and periodic examinations. Consider age, social/behavioral/medical factors, clinical findings, protective factors, and disease indicators.
• Assign low, moderate, or high risk. Use the overall balance and clinical judgment.
• Match care to the child. Individualize diagnostic, preventive, and restorative intensity to age, risk, and ability to follow prevention.

Assess risk, not just cavities

• Risk estimates the likelihood of new incipient/cavitated lesions or changes in existing lesion size/activity over time.
• Risk factors: contributors or predictors, including frequent sugar exposure, plaque, reduced saliva, appliances, health challenges, access to care, and social circumstances.
• Disease indicators: existing lesions and recent caries-related restorations demonstrate that disease-producing factors are present; they do not themselves cause caries.
• Protection: fluoridated water, daily fluoridated toothpaste, professional topical fluoride, and a dental home/regular care.
• Record applicable factors, weigh their balance, and explain the assigned category. One important factor, such as heavy plaque, may deserve greater weight; this is not a validated numerical score.
• Assessment also supports medical-provider referral of high-risk children and justification of service periodicity and intensity.

Ages 0–5: what changes the assessment?

• High-risk factors:
  • Active caries in mother/primary caregiver.
  • Caregiver lifetime poverty/low health literacy.
  • Sugar-containing snacks or beverages between meals >3 times/day.
  • Frequent sugar-containing bottle/nonspill cup use between meals or at bedtime.
  • Visible plaque.
  • Enamel defects.
• Moderate-risk factors: recent immigration and special health care needs.
• High-risk disease indicators: white-spot/noncavitated lesions, visible caries, recent restorations, or teeth missing because of caries.
• The protective-factor form includes optimally fluoridated water or fluoride supplements, daily fluoridated toothpaste, professional fluoride, and regular care.
• Special health care needs do not impose an unchangeable category: adjust for diagnosis and circumstances, particularly motor coordination and cooperation.

Ages ≥6: additional distinctions

• High-risk factors: lifetime poverty/low health literacy; between-meal sugar exposure >3 times/day; low salivary flow; visible plaque; enamel defects.
• Moderate-risk factors: recent immigration, medications that reduce saliva, special health care needs, intraoral appliances, and defective restorations.
• High-risk disease indicators:
  • Interproximal lesions.
  • New white-spot lesions.
  • New cavities or radiographic dentin lesions.
  • Restorations placed within 3 years for a new patient or 12 months for a patient of record.
• Protective factors: optimally fluoridated water, daily fluoridated toothpaste, professional topical fluoride, and a dental home/regular care.
• This age-group assessment form is intended for dental providers. Assess both whole-patient risk and individual-tooth risk.

Turn the assessment into a plan

• State the overall risk and the findings that drive it, then make a separate decision for each lesion.
• A noncavitated lesion may need active prevention and surveillance; a cavitated lesion may need arrest therapy, an interim restoration, or definitive restoration.
• Account for pulp status and the family's ability to carry out and return for care.

At review, compare lesion activity/progression and new disease with the prior examination, then reassess the exposures and protective measures. A completed restoration does not by itself justify lowering the patient's risk category.

Example care pathways: follow-up and fluoride

The following intervals appear in both age-group tables; they are examples for individualized care planning.

• Low/moderate-risk pathways: optimally fluoridated water and twice-daily fluoridated toothpaste.
• Moderate/high-risk pathways list supplements as an alternative when water supplies are fluoride deficient; this document gives no supplement dose schedule.
• High risk, ages 0–5: twice-daily fluoridated toothpaste plus professional topical fluoride every three months.
• High risk, ages ≥6: the table specifies brushing with 0.5% fluoride gel/paste, professional topical fluoride every three months, and optimally fluoridated water or the conditional supplement alternative.
• Parent-supervised toothpaste amounts: smear under age 3, pea-size ages 3–5; the older-child table specifically states supervised pea-size use at age 6.
• Dietary counseling and consideration of sealants appear in all risk categories.

Lesion management and prevention

• Surveillance: periodically check for progression; the low-risk pathway uses this approach.
• Active surveillance: parents and professionals actively reduce the cariogenic environment and closely monitor arrest/progression. Moderate/high-risk pathways use it for noncavitated white-spot lesions.
• Moderate/high-risk tables call for restoration of cavitated or enlarging lesions. Choose the patient-specific plan rather than assuming every early lesion needs operative treatment.
• High-risk pathways include 38% silver diamine fluoride for cavitated lesions to help arrest caries. Obtain informed consent that specifically addresses expected staining of treated lesions.
• Interim therapeutic restorations: may bridge care until permanent restorations can be placed in high-risk patients.
• Sealants: weigh patient risk and tooth anatomy/risk for primary and permanent molars. Expert opinion favors permanent-tooth sealants even in low-risk children because anatomy differs and risk may change, despite unfavorable cost/benefit findings in that group.

Evidence and uncertainty

• The update reviewed literature from 2012–2021; inadequate/inconclusive evidence led to expert or consensus recommendations.
• Validated multivariable pediatric prediction tools remain limited. The source identifies Cariogram and CAMBRA as validated; similar components do not establish validation of every tool.
• Past caries history is less useful in young children; lesion activity may matter more than lesion count. Salivary flow is difficult to measure and may be less relevant in this age group.
• Sugar frequency is difficult to quantify; social factors proxy exposures/behaviors. Lifespan prediction and age-related risk changes remain incompletely determined; genetic variation may contribute.
• Toothpaste, topical fluoride, SDF, and sealant recommendations draw on systematic reviews. Primary-tooth sealants were addressed by only the cited ADA/AAPD review. Supplements and radiographs draw on organizational guidance; ITR draws on AAPD policy/best practices.
• Active surveillance reflects the possibility of arrest without operative treatment and intervention when progression warrants it. The document does not assign one formal evidence grade to the entire pathway.

Common board traps

Answer aloud

A four-year-old has white spots, plaque, and frequent sweet drinks. How do you plan care?

White-spot lesions are disease indicators, and plaque and frequent sweet drinks increase risk.

• Complete the risk assessment, including protective factors and caregiver ability to follow the plan.
• Prevention: address diet and home fluoride/hygiene; use active prevention and surveillance.
• Follow-up: the source's high-risk pathway includes three-month recall/topical fluoride and a six-month radiograph example, individualized to findings.
• Cavitated or enlarging lesions may require restorative treatment as well as continuing disease control.

An adolescent has no new cavities but an appliance and saliva-reducing medication. Is the patient low risk?

Do not assign low risk solely because there are no new cavities.

• An intraoral appliance and saliva-reducing medication are moderate-risk factors in the age-six-and-older form; actual low salivary flow is a high-risk finding.
• Assess plaque, sugar frequency, disease indicators, and protective factors, then document the overall balance and a preventive plan.

Why consider sealants in a low-risk child?

Overall low risk does not mean every tooth has low risk: deep pits and fissures can be vulnerable, and future risk may change.

• The source includes an expert preference for permanent-tooth sealants, while acknowledging unfavorable cost-benefit evidence in low-risk children.
• Weigh the individual tooth's anatomy and likely benefit rather than present sealants as equally valuable for every low-risk patient.

How do the example caries pathways change follow-up as risk rises?

Increase preventive and diagnostic intensity while individualizing intervals to the patient's findings.

• These are examples in the AAPD pathways, not automatic radiograph orders.
• Use twice-daily fluoride toothpaste; the ≥6 high-risk row specifies 0.5% fluoride gel/paste, which must not be transferred to preschool children.
• Active surveillance means prevention plus monitoring of noncavitated lesions; restoration alone does not control disease.
