Effect of Ozone on Wound Healing after Surgical Removal of Impacted Mandibular Third molar
Master Abstract
Ozone (O3) is a gas best known for its protective role in the earth's ecological harmony , that is present in small amounts in atmospheric air . Ozone molecules are composed of three oxygen atoms and present naturally in the upper layer of atmosphere in abundance as long as sun is shining. It protects living organisms by surrounding the earth at altitudes of 50,000 to 100,000 feet from the ultra-violet rays.
Medical Ozone is made when medical grade oxygen is electrically activated (using an Ozone Generator) to form ozone. It is a mixture of the purest oxygen and purest ozone. According to its application, the ozone concentration may vary between 1 and 100 µg/ml (0.05-5%).
O3 is a powerful oxidant capable of interacting as metabolic & immune modulator as well as anti-microbial agent. Multiple microbiological & the biochemical studies justified that there are no doubts about the effectiveness of ozone in bacterial reduction. Among other things, ozone is used to purify drinking water and water in dental equipment and for sterilizing instruments for medical use.
PHD Title
Effect of photo activated disinfection on osseointegration of immediate implants placed in infected sockets
PHD Abstract
Traditionally, before placing dental implants, the compromised teeth are removed and the extraction sockets are left to heal from several months up to 1 year.
Photodynamic therapy or light-activated disinfection is a technology based on the production of free oxygen radicals capable of affecting the membranes of microorganisms.The technique is composed of a photosensitizer substance usually toluidine blue that can be activated by light with susceptible wavelength. The photosensitizer after its activation produces energy capable of transforming the surrounding oxygen into free radicals, the free radical then attacks the exposed microorganisms.
