Newly developed antibacterial agent could be used with conventional bonding systems effectively to decrease white spots; when used with Transbond XT™ light cure, the original SBS did not get affected, but when used with Unite™ self-cure bonding system, it led to reduced SBS significantly.

The resultant displacement in position of center of resistance is negligible; hence, there is no need of changing biomechanics during orthodontic treatment for a tooth with three wall infrabony defects. However, it is necessary to further study other infrabony defects like two wall or one wall defect, and their effect on position of CRes.

Anchorage refers to the resistance against displacement by anatomical structures and the control of anchorage is one of the main factors for determining the success of orthodontic treatment. Conventional means of anchorage system were extra-oral and intra-oral anchorage. Evolution of intra-oral skeletal anchorage provided “Absolute Anchorage” using dental implants, miniplates and mini implant for fixed appliances which demanded stationary type of anchorage. Success of orthodontic mini implant depends on root proximity of the screw, cortical bone thickness and placement angle. In this article, we have described a grid for site selection and a well designed standard placement guide to prevent the root proximity while insertion, and reduce the chance of implant failure.

Many appliances, labial and lingual have emerged with different mechanics for simultaneous intrusion and retraction. Nowadays, the temporary anchorage devices are advocated as a method of augmenting anchorage. The present case utilizes the conventional technique of archwire modification according to Hocevar in Begg's technique for true incisor intrusion and simultaneous retraction. A non-numeric approach analysis called esthetic analysis is used for lower third of face to evaluate the treatment results.

Dental environment is associated with significant risk of exposure to various microorganisms. Orthodontists are the second highest incidence of hepatitis B among dental professionals. [1] Dental patients and dental health-care workers may be exposed to a variety of microorganisms via blood, oral, and respiratory secretions. This occupational potential for disease transmission become evident initially when one realizes that most human microbial pathogens have been isolated from oral secretions. For the protection of both the doctor and the patient, sterilization techniques are important in preventing the spread of infectious disease. While there have been many studies documenting general dentists' increasing levels of infection control in their practices, [2] there have been few studies documenting the infection control procedures in orthodontic procedures. [3] Orthodontic instruments present special problems, since they have difficulty to clean hinge areas, sharp angles, cutting edges, or pointed ends that can be potentially damaged by corrosion using autoclave sterilizers that use water vapors. An orthodontic molar band and brackets is perhaps the most consistently contaminated part of the orthodontic armamentarium. Not only is it subjected to saliva, but also to microorganisms of the periodontal sulcus and bloodstream.
