Effect of two antimicrobial rinses and oral prophylaxis on preoperative degerming of saliva

摘要: Two degerming mouthrinses, a 1% povidone-iodine and 0.2% aqueous solution of chlorhexidine gluconate, were tested with regard to their effect on the saliva. The study comprised two parts. In first part 19 dental students good oral hygiene rinsed mouths at weekly intervals 10 ml solution. A control group 12 nurses healthy teeth gums plain water. second 11 adult patients periodontal disease used test rinses both before after prophylaxis including scaling teeth. Non-stimulated saliva was simpled immediately 5, 30, 60, 120 min each rinse. Part cultured blood agar plates show growth aerobic microbes. remainder poured over Dentocult dip-slide for determination number acidophilic bacteria. results showed that in water bacterial count increased spite When compared prerinse values, clearly reduced amounts Chlorhexidine 5 rinse about one logarithm more than povidone-iodine, did, also longer duration did not seem lower pre-rinse counts but slightly improve solutions. tests 28% subjects had no This absence dependent other flora cases positive test, bacteria decreased solutions according pattern revealed by plate cultures.
