Dental Management of Children with Special Health Care Needs

Speech Impairments

• Definition: Difficulties in producing speech sounds, fluency, or voice. It affects communication and can impact social interactions and learning.

Types of Speech Impairments

1. Articulation Disorders

• Difficulty in producing speech sounds correctly. This can include substitutions, omissions, additions, or distortions of sounds.
• Phonological Disorders: Patterns of sound errors. Children may simplify words, omit certain sounds, or substitute them with others.

1. Fluency Disorders

• Affect the flow of speech. The most common fluency disorder is stuttering, which involves repetitions, prolongations, and blocks in speech.
• Cluttering: Rapid and/or irregular speech rate, excessive disfluencies, and collapsing or omitting syllables.

1. Voice Disorders

• Problems with the quality, pitch, loudness, or resonance of the voice.
• Dysphonia: Hoarseness, breathiness, or strained voice. Can result from vocal cord nodules, polyps, or paralysis.
  • Resonance Disorders: Occur when there is an imbalance in how air flows through the nose and mouth during speech, leading to hypernasality or hyponasality.

Etiology of Speech Impairments

1. Developmental

• Occur during speech and language development. The cause is often unknown.
• Genetic Factors: Predisposition to speech and language disorders.
  • Hearing Loss: Affects the ability to hear and imitate sounds.
  • Intellectual Disability: Associated with delayed speech and language skills.

1. Acquired

• Result from illness, injury, or medical conditions that affect the brain or speech mechanism.
• Traumatic Brain Injury (TBI): Can affect speech, language, and cognitive skills.
  • Stroke: Can cause aphasia or dysarthria, affecting speech production and comprehension.
  • Neurological Disorders: Such as cerebral palsy, muscular dystrophy, or Parkinson’s disease.

1. Structural

• Occur due to abnormalities in the structures involved in speech production.
• Cleft Lip and Palate: Affects the formation of sounds, particularly those that require air pressure in the mouth.
  • Dental Malocclusions: Misalignment of teeth or jaws can affect articulation.
  • Vocal Cord Paralysis: Can result from surgery, injury, or neurological conditions.

Clinical Features (General)

• Difficulty being understood by others.
  • Frustration and communication difficulties:
  • Impact on social interaction and academic performance.
• Strained Communication Effort/reduced verbal communication.
  • Reluctance to speak or participate in oral activities.
• Voice problems.
  • Hoarseness, breathiness, or abnormal pitch; can cause discomfort or fatigue.
• Fluency disruptions.
  • Repetitions, prolongations, or blocks in speech, leading to anxiety and avoidance.

Oral Manifestations

• Articulation Errors:
  • Substitutions, omissions, distortions of sounds;
  • Difficulty producing specific phonemes.
• Fluency Issues:
  • Stuttering behaviors; prolongations and blocks.
• Voice Abnormalities:
  • Hoarseness or breathiness;
  • Inappropriate pitch or loudness.
• Muscle Weakness or Incoordination:
  • Difficulty controlling the muscles of the face, mouth, and throat;
  • Drooling or dysarthria.

Dental Considerations and Management

1. Establish Communication

• Use clear, simple language:
• Speak slowly and repeat as necessary.
  • Use visual aids:
• Pictures, gestures, and written words.
  • Be patient and supportive:
• Allow extra time for the patient to respond.

1. Behavior Management

• Create a calm and relaxed environment:
• Reduce anxiety and promote cooperation.
  • Positive reinforcement:
• Reward good behavior and effort.
  • Desensitization techniques:
• Gradually introduce dental procedures to reduce fear and anxiety.

1. Preventive Strategies

• Oral hygiene instruction:
• Teach proper brushing and flossing techniques.
  • Dietary counseling:
• Limit sugary snacks and drinks to reduce the risk of caries.
  • Fluoride therapy:
• Apply topical fluoride to strengthen enamel and prevent decay.

1. Adaptive Aids

• Use adaptive toothbrushes:
• Larger handles or electric toothbrushes for patients with motor impairments.
  • Mouth props:
• To keep the mouth open during procedures.
  • Suction devices:
• To manage saliva and prevent aspiration.
