NBDHE Management of Special Needs Patients Questions and Answers — Questions and Answers
Question 1: An 8-year-old patient with Autism Spectrum Disorder (ASD) is scheduled for their first dental visit. The patient is non-verbal and exhibits anxiety with new sounds and lights. Which of the following is the MOST effective initial approach for this appointment?
- Schedule a long appointment to complete all necessary procedures at once.
- Use a papoose board immediately to ensure safety and efficiency.
- Have the parent remain in the waiting room to encourage independence.
- Introduce instruments and procedures using the tell-show-do technique. (Correct answer)
Correct answer: Introduce instruments and procedures using the tell-show-do technique.
The tell-show-do technique is a foundational behavioral guidance method that involves explaining the procedure, demonstrating it in a non-threatening way, and then performing it. [20, 24] This approach helps to desensitize the patient and build trust by making the environment predictable, which is especially crucial for patients with ASD who may have sensory sensitivities and anxiety about unknown situations. [29] Scheduling a long appointment can be overwhelming, using restraints is a last resort, and having a parent present is often a positive reinforcer. [21]
Question 2: A new adult patient presents with a medical history of Down syndrome. During the intraoral examination, which of the following oral manifestations is the dental hygienist MOST likely to find?
- A high number of carious lesions
- Macroglossia (Correct answer)
- An increased number of permanent teeth (hyperdontia)
- Accelerated eruption of permanent teeth
Correct answer: Macroglossia
Macroglossia, or an enlarged tongue, is a common clinical finding in individuals with Down syndrome. [2, 5, 11] It can be a true enlargement or a relative macroglossia due to a smaller-than-normal oral cavity. Other common findings include delayed tooth eruption, congenitally missing teeth (hypodontia), and a lower caries risk, although they are at very high risk for severe periodontal disease. [6]
Question 3: A 75-year-old patient who uses a wheelchair for mobility arrives for their appointment. The patient has upper body strength but cannot bear weight on their legs. Which method is the safest and most appropriate for transferring this patient to the dental chair?
- Sliding board transfer (Correct answer)
- Two-person lift with one person at the torso and one at the legs
- Having the patient independently pivot and transfer
- Treating the patient directly in their wheelchair
Correct answer: Sliding board transfer
A sliding board transfer is the ideal method for a patient who cannot bear weight but has sufficient upper body strength to assist. This technique bridges the gap between the wheelchair and the dental chair, allowing the patient to slide across with guidance and support, minimizing the risk of injury to both the patient and the clinicians. While a two-person lift is a valid technique, it is typically used for patients who cannot assist in the transfer at all. [1, 38]
Question 4: Which of the following is a frequent oral health complication in patients with cerebral palsy, directly resulting from their neuromuscular condition?
- Enamel fluorosis
- Gingival hyperplasia
- Bruxism and attrition (Correct answer)
- Delayed tooth eruption
Correct answer: Bruxism and attrition
Patients with cerebral palsy often experience involuntary muscle contractions and spasticity, which can lead to habitual, non-functional grinding (bruxism) and clenching. [4, 12] This can cause significant wear and tear on the occlusal surfaces of the teeth, known as attrition. While gingival hyperplasia can occur, it is typically a side effect of seizure medications (e.g., phenytoin) that some patients with cerebral palsy may take, not a direct result of the neuromuscular condition itself. [4]
Question 5: A new patient who is deaf arrives for their appointment and communicates primarily through American Sign Language (ASL). The dental office does not have a staff member who knows ASL. According to the Americans with Disabilities Act (ADA), what is the MOST appropriate initial step?
- Rely on written notes for the entire appointment to communicate.
- Ask the patient's accompanying family member to interpret.
- Proceed with treatment, using gestures to communicate.
- Ask the patient their preferred method of communication and if they require a qualified interpreter. (Correct answer)
Correct answer: Ask the patient their preferred method of communication and if they require a qualified interpreter.
The Americans with Disabilities Act (ADA) requires healthcare providers to ensure effective communication with patients with disabilities. [15, 19] The first and most critical step is to consult the patient to determine their preferred communication method. [17] The office is legally obligated to provide a qualified interpreter or other auxiliary aid if necessary for effective communication, especially for complex discussions like treatment planning and consent. Relying on family members is discouraged due to potential privacy (HIPAA) violations and lack of interpreting proficiency. [27]
Question 6: An elderly patient on multiple medications for hypertension and depression complains of a constantly dry mouth. This xerostomia places the patient at a significantly increased risk for which oral condition?
- Root caries (Correct answer)
- Periodontitis
- Candidiasis
- Geographic tongue
Correct answer: Root caries
Xerostomia, a common side effect of polypharmacy in geriatric patients, drastically reduces saliva's protective functions, including lubrication, cleansing, and buffering of acids. This, combined with age-related gingival recession that exposes root surfaces, creates a high-risk environment for the development of root caries. The dentin on root surfaces is much more susceptible to demineralization than enamel.
