Magnets have been used in dentistry for many years. Initially they were used to aid retention of dental prostheses when used as jaw implants. Over the last decade magnets have been used in orthodontics and dentofacial orthopedics and attempts have been made to evaluate the biological implications of magnets and magnetic fields during clinical application. The force they deliver can be directed, and they can exert their force through mucosa and bone, as well as within the mouth. The purpose of this article is to give a general idea about the different types of magnets used in dentistry, their physical properties, their biological safety and gross reviews of various reported works by different authors so far.

Orthodontics like any otherlscience is constantly undergoing development and is evolving through the discovery of newer techniques, materials and improvement of older ones. The concept of "bonding in orthodontics" has been a monumental step in the progress of our science. One of the most daunting tasks for Orthodontists during the bonding procedures is the strict maintenance of a dry field, which is often very difficult. For nearly 20 years, cyanoacrylate glues have been widely used in Dentistry as well as in Medicine. Although toxic and mutagenic properties of cyanoacrylates. particularly lower cyanoacrylates, have been reported. they are generally considered safe for medical and dental use. The present study was undertaken to compare the shear bond strength of this new generation bonding adhesive (Smartbond) with a conventionally used dental composite (Right on) bonding agent (TP Orthodontics).
