✍️ Sample COM Questions & Answers

1. Which of the following is a common approach to treatment planning for patients with myofunctional disorders?
Combination of exercises, behavioral changes, and orthodontics.

Myofunctional disorders often stem from improper muscle function and oral habits, which can also impact dental alignment. Therefore, treatment typically involves a combination of targeted myofunctional exercises to retrain muscles, behavioral changes to eliminate harmful habits (like tongue thrust), and often orthodontic interventions to correct any resulting dental or jaw malalignment. This integrated approach addresses both the functional and structural aspects for comprehensive improvement.

2. What should a COM professional do upon discovering a colleague's unethical conduct?
Report through appropriate channels with proper documentation

Professionals have an obligation to report misconduct through proper channels while documenting observations to support investigation.

3. When a child presents with suspected enlarged adenoids causing significant nasal obstruction, the appropriate management sequence is:
Refer to an ENT physician to evaluate and treat the adenoid obstruction before initiating OMT

Enlarged adenoids create an anatomical barrier to nasal breathing; OMT cannot overcome structural obstruction, so ENT evaluation and potential adenoidectomy must precede myofunctional training.

4. What is scope creep in COM project management?
Uncontrolled scope expansion without adjusting time, cost, or resources

Scope creep adds requirements without formal evaluation, causing schedule delays and budget overruns.

5. Nail biting (onychophagia) is relevant to orofacial myofunctional therapy primarily because it:
Maintains an oral habit and keeps the mouth open, disrupting nasal breathing patterns

Nail biting perpetuates an oral habit pattern, often keeping the lips apart and disrupting the nasal breathing posture that myofunctional therapy seeks to establish.

6. What is a COM professional's obligation regarding confidentiality?
Protecting client information and disclosing only with authorization or legal requirement

Confidentiality requires protecting all client information from unauthorized disclosure, sharing only with consent or legal mandate.
