Evaluation of Bond Strength: An In vitro Study using Pro Seal.

Background: Fluoride releasing bonding agent were introduced to take care of white spot lesions. However, their clinically handling properties are less than ideal, deterring many practitioners. Reliance orthodontic products (Itacsa, I11) recently released an enamel sealant named Pro Seal to be used with bonding agents.

Dentoskeletal Comparison of Changes Seen in Class II Cases Treated by Twin Block and Forsus.

Background: To evaluate skeletal and dentoalveolar effects of Forsus fatigue resistant devices (FRD) and twin-block (TB) appliance in Class II malocclusion cases.

Materials And Methods: Twenty young adult patients (age 13-17 years, overjet 6-10 mm) with a Class II division 1 malocclusion were randomly divided into two groups: group I included 10 patients treated with TB, Group II included 10 patients treated with FRD. Dentoskeletal changes were analyzed on lateral cephalograms taken before (T1) and (T2) at the end of the treatment.
