Nano-Periodontics: A Step Forward In Periodontal Treatment

Abstract

The term “Nano” refers to a unit of measurement that is equal to one billionth of a kilometer (10-9). To get closer to “how much Nano is”, it is worthy to know that the length of a normal human being ranges from one and a half to two meters, while, if we move to something smaller, such as a mobile phone, it can be measured by 12 cm, and if we move to smaller things, ants for example are about 2 mm long, while if we take a human hair, its diameter measures about 100 micrometers. Viruses are much smaller ranging in size between 30 and 50 nanometers, and a DNA molecule has a size of about 2.5 nanometers. Taking into account that the approximate size of the sun is 1.4 billion meters, this means that a nanoparticle for a human is the same as the size of a human in relation to the sun [1].
