The effectiveness test of 0.9m nacl solution and 0.2% chlorhexidine gluconate on bacterial growth in the oral cavity of students batch 2018 at medical faculty, Universitas Kristen Indonesia

Abstract

Mouth rinse that is natural, safe, cost-effective, readily available and culturally acceptable is required as an adjunct to routine tooth brushing to combat dental diseases. Gargling with 0.9 M NaCl solution and Chlorhexidine Gluconate 0,2% can reduce the number of bacteria in the oral cavity. The purpose of this study was to determine the effectiveness of using 0,9M NaCl solution and Chlorhexidine Gluconate 0, 2% for decreasing the number of germs in the oral cavity of FK UKI Class 2018 students. This study was conducted experimentally by wiping the oral cavity of students before and after treatment. Thirty-two student samples met the inclusion criteria. The results showed quantitatively, Chlorhexidine Gluconate 0.2% could reduce the number of bacteria by 89.25%, while 0.9M NaCl solution was only able to reduce the number of bacteria by 27.05%, with the results of T dependent test p <0.005, which shows both solutions are effective in reducing the number of germs in the oral cavity. The results of the identification of this study found positive Gram round bacteria. The conclusion from this study shows that both types of mouthwash can significantly reduce the number of bacterial colonies in the mouth, and saltwater rinse can be used as an adjunct to routine mechanical plaque control for the prevention of oral diseases.
