    Abstract:
    This study is conducted to determine the different types of microorganisms found in the saliva of individuals with varying degrees of oral hygiene, also to determine the effectiveness of 1% Povidone Iodine (Betadine) 1% gargle oral antiseptic as a pre-procedural mouthrinse in individuals with varying degrees of oral hygiene, and lastly to be able to determine the duration of the effectiveness of the solution. The cheek mucosa of the patients are procured of saliva specimens without prior rinsing of 1% Povidone Iodine and the saliva sample obtained was placed on a test tube with thioglycollate culture media and was labelled. The patients are asked to rinse or to gargle immediately with 1% Povidone Iodine at full strength (20ml.) for about 30 seconds. After two hours, the cheek mucosa was then again swabbed and placed on the second test tube. After four hours, the same procedure was done and the saliva specimen obtained was labelled and placed on the third test tube. The result of this study revealed that 1% Povidone Iodine used as a pre-procedural mouthrinse has a bactericidal effect in the microorganism concentration resulting to the reduction of surviving microorganisms up to four hours which is the limitation of the study.
