CBCT imaging - A boon to orthodontics.

The application of innovative technologies in dentistry and orthodontics has been very interesting to observe. The development of cone-beam computed tomography (CBCT) as a preferred imaging procedure for comprehensive orthodontic treatment is of particular interest. The information obtained from CBCT imaging provides several substantial advantages.

Soft tissue changes associated with first premolar extractions in adult females.

Background: The potential for premolar extractions to produce changes in the soft tissue profile after orthodontic treatment is controversial.

Aim: To evaluate the soft tissue changes associated with four first premolar extractions in adult females of South Indian ethnicity.

Method: Pre- and post-treatment lateral cephalometric radiographs of 30 adult female patients of South Indian ethnicity with bimaxillary dentoalveolar protrusion, requiring premolar extractions as a part of their orthodontic treatment, were used.
