Brief summary

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.

Detailed description

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
