26 Primary Colonisation of DUWL by P.aeruginosa and its Ergication by Ozone

H.AlShorman et al.

Pseudomonas aeruginosa (P.a.) is a gram negative bacteria that poses a considerable risk on immuno- compromised and in particular cystic fibrosis patients. It is one of the bacteria that inhabits water sources. Along with Mycobacteria and Legionella it forms the most significant environmental bacteria in terms of health hazard to patients treated in the dental office.

Ozone is a potent microbicide and is used for disinfection of water in swimming pools and drinking water.1 In dentistry, it was shown to be effective in the treatment of Primary Root Caries and Primary Occlusal Pit and Fissure Caries.
