Aim and objective: The aim of this study is to investigate pain and discomfort experienced among patients undergoing orthodontic treatment with different types of crowding for a period of one month after the insertion of the appliance.

 Background: The movement of teeth by orthodontic appliances typically causes some discomfort to the patient. It has been reported that fear of pain is a key factor discouraging a patient from seeking orthodontic treatment.  Pain, induced by orthodontic treatment, generally could be categorized as mild and short lasting. Discomfort is expressed as unpleasant tactile sensations, feeling of constraint in the oral cavity, stretching of the soft tissues, pressure on the mucosa, displacement of the tongue, soreness of teeth and pain. During the orthodontic treatment patients frequently undergo a number of functional complaints and social discomfort and they are anxious about their appearance. The pain and discomfort perceived by each patient may vary.

 Reason: To evaluate the pain and discomfort experienced by patients with different types of crowding after the insertion of the arch wire.

Methodology: A questionnaire study is to be conducted among the patients undergoing orthodontic treatment.
