Parafunctional activity

Parafunctional Activity

Parafunctional activity refers to the various oral habits that can potentially cause harm to the oral structures or alter their function. These activities are not associated with the normal functions of the mouth such as speaking, eating, or breathing. They are often unconscious and can occur during both the day and night.

Types of Parafunctional Activities

There are several types of parafunctional activities, including:

• Bruxism: This is the grinding or clenching of teeth, often during sleep. It can lead to tooth wear, jaw disorders, and other problems.
• Tongue thrusting: This involves pushing the tongue against the teeth when swallowing, speaking, or at rest. It can lead to orthodontic problems and changes in the bite.
• Mouth breathing: This is breathing through the mouth instead of the nose. It can lead to dry mouth, bad breath, and other issues.
• Thumb sucking: This is a common habit in children that can lead to changes in the shape of the mouth and teeth.

Causes of Parafunctional Activities

The exact causes of parafunctional activities are not fully understood. However, they are often associated with stress, anxiety, sleep disorders, and other psychological factors. Some studies also suggest a genetic component.

Treatment of Parafunctional Activities

Treatment for parafunctional activities depends on the specific activity and its effects. It may include behavioral therapy, physical therapy, dental appliances, medication, or surgery. In some cases, no treatment is necessary.
