Effect of 3 Week vs 6 Week Orthodontic Appointment Intervals on Teeth Alignment

Effect of 3 Week vs 6 Week Orthodontic Appointment Intervals on Teeth Alignment in Patients With Moderate to Severe Dental Crowding: a Randomized Clinical Trial

Effect of 3 week vs 6 week orthodontic appointment intervals on teeth alignment in patients with moderate to severe dental crowding: a randomized clinical trial.

There is still inconclusive evidence about the orthodontics treatment duration and interappointment interval.

Patients with moderate to severe crowding will be divided randomly into two groups (Group A and Group B). Group A includes patients with an interval of 3 weeks between their appointments while Group B includes the patients with an interval of 6 weeks between their appointments.

1. To determine the mean changes in the tooth irregularity index of a patient with mild to moderate crowding activated every 3rd week
2. To determine the mean changes in the tooth irregularity index of a patient with mild to moderate crowding activated every 6th week
3. To compare the difference between the two modalities in percentage
