Recently the use of dental implants for the replacement of missing teeth in growing children has gained popularity among pediatric dentists. But again when and in which situations it can be used in growing children is a big dilemma. Factors that favor implant placement in children are their excellent local blood supply, good immunobiologic resistance, and enhanced osseous healing. But the dentist should be aware of the potential risks in placing implants in growing children as it can affect their craniofacial growth because the jaws are still growing and developing.

Fluoride is a trace element which is well known for its anticariogenic potential.Various forms of fluoride has been used in dentistry such as fluoride varnishes, dentifrices, restorative materials etc. The cariostatic action associated with fluoride-releasing materials is usually attributed to a sustained release of fluoride. Due to the fact that fluoride levels leached from fluoride containing filling materials decreased over time, the "recharging" of restoratives with fluoride has been suggested. Rechargeability is the ability of the material to take up fluoride and release it over a longer duration of time to prevent tooth decay.The ability of a restorative to act as a fluoride reservoir is mainly dependent on the type and permeability of filling material, on the frequency of fluoride exposure and on the kind and concentration of the fluoridating agent.
