Unilateral transposition has been reported more often than bilateral transposition, with the left side of the body being affected more frequently than the right. With a frequency rate of 0.03 percent, the Mn.I2.C transposition is the rarest of all transpositions. In this unusual case report on a mandibular lateral incisor-canine transposition, dento-alveolar concerns such as arch length disparities and tooth material differences are addressed (Mn.I2.C).

The present study was conducted to assess the effect of adhesion boosters on shear bond strength (SBS) of orthodontic brackets on bleached teeth. Materials & Methods: 60 maxillary premolars teeth were randomly divided equally into 2 groups. Group I were bleached teeth and group II had non-bleached teeth. Each group was further divided equally into 3 subgroups (n = 10) depending on the type of adhesive booster used (Enhance LC, All-bond 2, and no adhesive booster [control]). Maxillary premolars brackets were bonded. Debonding was done with a universal testing machine, and the SBS was recorded. Results: The mean shear bond strength (MPa) in Group IA was 10.5, in IB was 13.2, in IA was 10.5, in IC was 14.3, in IB was 13.2, in IC was 14.8, in IIA was 9.8, in IIB was 11.2, in IIA was 9.8, in IIC was 12.3, i...

A web-based survey study and was conducted in Department of Orthodontics and Dentofacial Orthopaedics. This survey was conducted for a period of 10 months and included orthodontists practicing in India. The questionnaire comprised of 53 questions which were divided in seven parts containing multiple choice questions, tabular and free response questions. These seven parts gathered information about socio-demographic status of the respondent, selection of retention system, removable and fixed retainer choices, duration and supervision of retention period and instruction given to patients. Dual retention, fixed retainers with vacuum formed retainers was the common type of retention in both arches with extraction largely influencing the choice of retainer. The bonded wire from canine to canine is the most frequent fixed ...
