Abstract

Objective: To compare handrubbing and handwashing effectivity on total bacteria count on clinical students at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Universitas Sumatera Utara March - May 2018.Material and  Methods: This is an experimental study with pre-test pos-ttest group design carried out by purposive sampling technique. In this study, sample were divided into 2 groups and each consist of 20 people which are handrubbing and handwashing groups. Bacterial samples were obtained by placing the right hand in a container that contain NaCl 0.9% solution for 1 minute. Samples were then grown in nutrient agar plate and incubated at 37°C for 48 hours. The culture results were calculated using the colony counter tool.Results: There is a significant difference before and after handrubbing with significance 0.00 (P<0.05) and before and after handwashing with significance 0.001 (p<0.05) in reducing bacterial colonization in hand with. However, there is no significant association between handrubbing and handwashing method in reducing the number of bacterial colonization with a significance number of 0.892 (p> 0.05).Conclusion: There is no significant differences between handrubbing and handwashing in reducing the number of bacterial colonization.

Abstract

Objective: To compare the effect of rubbing and soaking tooth extraction instrument in 70%  alcohol on total oral bacterial colonisation at the Department of Oral Surgery, Faculty of Dentistry, Universitas Sumatera Utara. Material and Methods: This is an experimental research with a post-test only approach. The sampling technique used is Purposive Sampling. In this study, sample were divided into 2 groups consisting of 18 extraction instruments which are lower molar forceps rubbed with 70% alcohol and soaked in 70% alcohol. Each instrument were pre-cleaned using brush, water and soap prior disinfection process.Results: The results were statistically analyzed using Mann-Whitney Test. The result showed no significant difference to the total bacteria count on rubbing and soaking using 70% alcohol.Conclusion: Soaking in 70% alcohol method showed more effective because it overally kills bacteria.Keyword:

Abstract

Objective: To compare between Effectivity of Povidone Iodin 1% Application With Swab Technique and Rinse To the Number of Bacteria Colonization As An Aseptic Action at the department of oral surgery, Faculty of Dentistry, Universitas Sumatera Utara.Material and  Methods: This was an experimental study with post-test only control group design approach. Purposive technique is applied to collect samples which are clinical students. In this study, sample were divided into 4 groups and each consisting of 10 people. The sample was divided into negative control group with 0.9% normal saline and 1% povidone iodine treatment group with two techniques which is swab and gargle.Results: Based on Mann-Whitney test result on 1% Povidone Iodin group which was rinse and  swab technique obtained p-value = 0.382 where p-value > 0,05 so it can be concluded that there is no significant difference between 1 % Povidone Iodine in rinsing technique and 1% Povidone Iodine in swabbing.Conclusion: Rinsing was more effective than swab as an aseptic action with 1% Povidone Iodine.

Abstract

Objective: To compare chlorhexidine digluconate 0.12% and povidone iodine 1% on total bacterial count after mouth rinsing at the department of oral surgery, Faculty of Dentistry, University of Sumatera Utara Material and Methods: This was an experimental study with post-test only control group design approach. Purposive technique was applied to collect samples which are clinical students. In this study, sample were divided into 3 groups and each consisting of 12 people. Normal saline 0.9% was used as control group while chlorhexidine digluconate 0.12% and povidone iodine 1% was used as the treatment group. Each member performed mouth rinsing for 30 seconds. Results: The results were statistically analyzed using Kruskal Wallis and Mann-Whitney test. The comparison between chlorhexidine digluconate 0.12% and povidone iodine 1% showed a significant difference to the total bacteria count after mouth rinsing (p<0.05) and the chlorhexidine digluconate 0.12% group showed a greater mean reduction. Conclusion: Chlorhexidine digluconate 0.12% reduce more bacteria than povidone iodine 1%. However, both of the antiseptic agents can be a choice for mouth rinsing.
