AimIn this, in vitro study’s objective is to assess the shear bond strength (SBS) of metal and ceramic orthodontic brackets that have been adhered to enamel using a conventional acid etch/primer and self-etching primer (SEP) adhesive method. Materials and MethodsOne hundred excised human premolars were bonded on brackets and were divided into group 1 –Metal brackets were bonded on teeth and group 2 –Ceramic brackets were bonded on teeth. These two groups were further subdivided: subgroup 1a – 25 metal brackets bonded using conventional acid etch/primer adhesive system, subgroup 1b – 25 metal brackets bonded using SEP, subgroup 2a – 25 ceramic brackets bonded using conventional acid etch/primer adhesive system, and subgroup 2b – 25 ceramic brackets bonded using SEP; brackets were debonded using a computerized Instron universal testing machine. ResultsThe mean value of SBS of metal and ceramic brackets bonded using conventional acid etch/primer adhesive systems had higher SBS than those bonded using SEP. SBS ranged from 7.95 to 12.24 MPa which was in the acceptable clinical range. ConclusionSBS values of all four subgroups exceeded the range of 6–8 MPa observed to be acceptable for routine clinical use.

Aim: In this, in vitro study's objective is to assess the shear bond strength (SBS) of metal and ceramic orthodontic brackets that have been adhered to enamel using a conventional acid etch/primer and self-etching primer (SEP) adhesive method. Materials and Methods: One hundred excised human premolars were bonded on brackets and were divided into group 1 -Metal brackets were bonded on teeth and group 2 -Ceramic brackets were bonded on teeth. These two groups were further subdivided: subgroup 1a - 25 metal brackets bonded using conventional acid etch/primer adhesive system, subgroup 1b - 25 metal brackets bonded using SEP, subgroup 2a - 25 ceramic brackets bonded using conventional acid etch/primer adhesive system, and subgroup 2b - 25 ceramic brackets bonded using SEP; brackets were debonded using a computerized Instron universal testing machine. Results: The mean value of SBS of metal and ceramic brackets bonded using conventional acid etch/primer adhesive systems had higher SBS than those bonded using SEP. SBS ranged from 7.95 to 12.24 MPa which was in the acceptable clinical range. Conclusion: SBS values of all four subgroups exceeded the range of 6-8 MPa observed to be acceptable for routine clinical use. [ABSTRACT FROM AUTHOR]

Background: En masse retraction of the anterior teeth may create anchorage problems. The effective means of obtaining anchorage in en masse retraction is by the usage of temporary anchorage devices. Aims and Objectives: The purpose of this study is focused on stress and strain created around miniscrew during en masse retraction using the cone beam computed tomography (CBCT) data obtained at two intervals and by the finite element analysis done using the CBCT data obtained. This will show us the stress and strain created around miniscrews and the withstanding capacity of miniscrews. Conclusion: Stress and strain was higher in TADs as compared to cortical and alveolar bone. [ABSTRACT FROM AUTHOR]

In our daily clinical practice it is very important for us to get organized in our clinics in such a way that we should spend more time on patient and less time on arranging our instruments and other orthodontic accessories. We have designed a cheap, compact and handy spools and elastic ties organizer, which will compact all these spools and ties at one place and in a more organized way. [ABSTRACT FROM AUTHOR]

The majority of the patients with Class II division 1 malocclusions have the presence of underlying skeletal discrepancy between maxilla and mandible. 2 basic strategies for the treatment of Class II division 1 malocclusion in children are common: 1) Treatment in 2 phases, one started early in pre-adolescent and second during adolescent years, 2) treatment in single phase of active treatment during the adolescent years. Both the strategies have their own advantages and disadvantages. Early treatment for Class II malocclusion is frequently undertaken with the objective of correcting skeletal disproportion by altering the growth pattern. Growth modification is the interceptive mode of intervening in the developing Class II skeletal condition. Growth modification procedures are normally carried out during mixed or early permanent dentition before the cessation of active growth. The goals of growth modification is to alter the unacceptable skeletal relationship by modifying the patient's remaining facial growth to favorably change the size, orientation and position of the jaws. The overall treatment of skeletal Class II depends upon the age of the patients, growth potential, severity of malocclusion, whether dental or skeletal and associated malocclusion.
