Exam 2 Rationale Study Guide NSG5442 Pediatric NP South College
I. Oral Health & Dental Disorders
Case 1: Newborn Oral Findings and Early Development
Scenario
A 2-week-old full-term infant presents for a routine visit. The infant feeds
every 2–3 hours, has appropriate weight gain, and shows no signs of
distress.
During the oral exam, multiple small, white, firm nodules are noted along
the alveolar ridge. There is no erythema, swelling, or feeding difficulty.
The parents are concerned that this may represent an infection or abnormal
tooth development. They also ask when teeth typically begin to erupt and
when children start losing baby teeth.
What to Focus On
1. Normal newborn oral findings
2. Tooth eruption timeline
3. Timing of primary tooth loss
4. When referral is not needed
Clinical Reasoning
The white nodules are Epstein pearls, a common benign finding in
newborns that resolve spontaneously and do not require treatment or
referral.
Primary teeth erupt in a predictable sequence, beginning with the central
incisors, and children typically begin losing primary teeth around 6–7
years of age.
Recognizing normal findings allows appropriate reassurance and avoids
unnecessary intervention.
Case 2: Dental Caries, Prevention, and Referral
Scenario
A 6-year-old child presents with visible dental caries, intermittent tooth
,pain, and difficulty chewing. The caregiver reports frequent sugary snacks
and inconsistent brushing habits.
At a follow-up visit, newly erupted permanent molars are noted, and the
caregiver asks how to prevent further cavities.
What to Focus On
1. Consequences of untreated caries
2. Fluoride role in enamel protection
3. Dental sealant indications
4. When referral is required
Clinical Reasoning
Untreated dental caries can progress to infection, abscess formation,
and systemic complications, making early treatment essential.
Fluoride promotes enamel remineralization and resistance to acid
damage, but high-risk surfaces—such as the deep grooves of permanent
molars—require additional protection.
These molars are ideal candidates for dental sealants.
This child requires referral to a dentist for both treatment of existing
caries and preventive care.
Case 3: Bruxism and Temporomandibular Dysfunction (TMJ)
Scenario
An 8-year-old child is brought in for nighttime teeth grinding. The child has
no pain, jaw dysfunction, or visible dental damage.
In a separate visit, a 13-year-old presents with jaw pain, clicking, and
discomfort during chewing. Symptoms worsen with prolonged chewing and
improve with rest.
What to Focus On
1. Bruxism in children
2. TMJ dysfunction features
3. Initial management
4. Referral criteria
, Clinical Reasoning
Bruxism in children is typically benign and self-limited, often requiring
only observation and reassurance.
Temporomandibular joint dysfunction presents with pain, clicking, and
muscle strain.
Initial management is conservative, including:
1. Soft diet
2. Jaw rest
3. Warm compresses
Referral is appropriate if symptoms persist, worsen, or cause functional
limitation.
Case 4: Oral Hygiene Challenges in Special Populations
Scenario
A 6-year-old child with autism spectrum disorder has difficulty tolerating
tooth brushing due to sensitivity to taste, texture, and sound. The caregiver
reports frequent resistance, leading to inconsistent oral hygiene and visible
plaque buildup.
What to Focus On
1. Sensory processing challenges
2. Adaptation of oral care techniques
3. Behavioral strategies
4. Role of dental referral
Clinical Reasoning
Children with sensory sensitivities require an individualized, stepwise
approach to oral care. Helpful strategies include:
1. Using non-foaming or mild-flavored toothpaste
2. Selecting soft-bristle toothbrushes
3. Gradual desensitization
Forcing oral hygiene can increase resistance.
Referral to a pediatric or special needs dentist supports long-term
adherence and preventive care.
