COM COM Pediatric & Developmental Considerations 2 — Questions and Answers
Question 1: Which dental malocclusion is most frequently associated with a persistent anterior tongue thrust swallowing pattern?
- Anterior open bite (Correct answer)
- Class II deep bite
- Unilateral posterior crossbite
- Skeletal Class III
Correct answer: Anterior open bite
Anterior open bite is most frequently associated with a persistent tongue thrust swallow because the tongue exerts habitual forward pressure that prevents anterior tooth contact.
Question 2: What role does a COM play in addressing digit sucking habits in children?
- Prescribing orthodontic habit appliances
- Performing myotomy to reduce digit sensitivity
- Providing behavior modification and habit-elimination programs (Correct answer)
- Administering topical deterrent medications
Correct answer: Providing behavior modification and habit-elimination programs
COMs address digit sucking through structured behavior modification and habit-elimination programs, which are within their professional scope and effective for most children.
Question 3: Why is intervention during the active craniofacial growth period significant for children with myofunctional disorders?
- Therapy risks are higher during rapid growth phases
- Therapy is only effective after skeletal maturity
- Functional corrections during growth may positively redirect facial development (Correct answer)
- Growth has no relationship to therapy outcomes
Correct answer: Functional corrections during growth may positively redirect facial development
Correcting dysfunctional muscle patterns during active growth can positively redirect craniofacial development, potentially reducing the need for more extensive orthodontic or surgical intervention later.
Question 4: What infant feeding difficulty may signal an orofacial myofunctional disorder requiring early assessment?
- Preference for pureed over solid textures at 12 months
- Refusal to use a pacifier
- Difficulty latching and sustaining breastfeeding (Correct answer)
- Sleeping with the mouth slightly open
Correct answer: Difficulty latching and sustaining breastfeeding
Difficulty latching during breastfeeding may indicate ankyloglossia or other myofunctional issues, warranting early assessment to support feeding success and normal oral development.
Question 5: Which professional should a COM consult when a pediatric patient presents with both orofacial myofunctional disorders and speech sound errors?
- Pediatric neurologist
- Pediatric dentist
- Oral surgeon
- Speech-language pathologist (Correct answer)
Correct answer: Speech-language pathologist
A speech-language pathologist should be consulted when a child presents with speech sound errors alongside orofacial myofunctional issues, as both areas require coordinated interdisciplinary care.
Question 6: What is the primary objective of lip seal training in pediatric orofacial myofunctional therapy?
- Strengthening the orbicularis oris for improved dental alignment
- Developing nasal breathing as the habitual respiratory pattern (Correct answer)
- Eliminating anterior open bite through lip pressure
- Reducing salivary flow during eating
Correct answer: Developing nasal breathing as the habitual respiratory pattern
Lip seal training primarily aims to establish nasal breathing as the habitual resting pattern by achieving consistent anterior lip closure at rest.
