Abstract

Low intensity laser therapy (LILT) is currently undergoing investigation as a treatment for chronic wounds. Although the intended target is the wound bed and surrounding skin, wound bacteria are also exposed and hence subject to LILT, thus a good understanding of the effects of LILT on bacterial growth is essential for prescribing safe and effective laser therapy for wounds. The present work examines the effects of 810 nm laser on bacterial growth. The objectives were: 1. to determine an effective combination of radiation parameters leading to bacterial inhibition, or alternatively 2. to determine which combination of laser parameters produce the least stimulation of bacterial growth.
