Abstract

Objective: To compare Chloroxylenol 4.8% and Povidone Iodine 7.5% on total bacterial count post WHO routine hand washing on clinical students at the department of oral surgery, Faculty of Dentistry, Universitas Sumatera UtaraMaterial 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 3 groups and each consisting of 10 people. Aquadest was used as control group while Chloroxylenol 4.8% and Povidone Iodine 7.5% was used as the treatment group. Each member performed routine handwashing using WHO method for 1 minute long.Results: The results were statistically analyzed using Kruskal Wallis and Mann-Whitney Test. The comparison between Chloroxylenol and Povidone Iodine showed no significant difference to the total bacteria count after handwashing (p>0.05) but the Chloroxylenol group showed a greater mean reduction.Conclusion: Chloroxylenol and Povidone Iodine are capable reducing the number of bacteria in hands, therefore it can be a good antiseptic choice for hand washing.

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 determine the effectiveness of gotu kola leaf extract gel (Centella asiatica (L.) Urban) as an antimicrobial against the growth of Staphylococcus aureus bacteria in vitro and the most effective concentration in inhibiting the growth of Staphylococcus aureus bacteria.Materials and Methods: This study is a laboratory experimental study with a post-test only control group design. The research sample used Staphylococcus aureus bacteria which was bred and cultured in the Microbiology Laboratory of the Universitas Sumatera Utara Hospital. The research sample was divided into 5 treatment groups, namely gotu kola leaf extract gel 1%, 2.5%, 5%, Chlorhexidine digluconate 0.2% (positive control) and DMSO (negative control). The test for the five groups was repeated 5 times with the Kirby-bauer diffusion method.Results: The results showed the effectiveness of gotu kola leaf extract gel at a concentration of 2.5% and 5% with an inhibition zone diameter of 6.8 mm and 9.4 mm, respectively, while at a concentration of 1% there was no inhibition zone found. The data were statistically analyzed using the Kruskal-wallis and Mann-Whitney tests showing a significant difference in each treatment group (p <0.05), but there was no significant difference between the 1% and negative control groups (p> 0.05).Conclusion: Gotu kola leaf extract gel was effective in inhibiting the growth of Staphylococcus aureus bacteria in vitro at concentrations of 2.5% and 5%. The 5% concentration is more effective than other concentrations.

Abstract

Objective: To compare the efficacy of 4% articaine and 2% mepivacaine for local infiltration during maxillary molar extraction at Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Universitas Sumatera Utara. Material and Methods: This was an experimental study with two group post-test only control group design. Sample were divided into 2 groups and each group consisted of 15 patients received 4% articaine and 2% mepivacaine. The time of onset of action were recorded using dental probe at intervals 15s and intra-operative pain were assesed using visual analog scale during the procedure. Results: The results were statistically analyzed using independent T-test. The comparison between 4% articaine and 2% mepivacaine showed significant difference in the mean of onset time (p = 0,00 < 0,05) and no significant differences in the intraoperative pain between 4% articaine and 2% mepivacaine for local infiltration during maxillary molar extraction (p = 0,78). Conclusion: Articaine 4% has clinically achieved faster onset, comparable to mepivacaine in infiltrative techniques for maxillary teeth extraction. However, there were no significant differences between them in relation to the intensity of intra-operative pain.

Abstract

Objective: In the act of extracting teeth, the discharge of blood cannot be avoided. This can be overcome normally because of the hemostatic process that stops bleeding. One ingredient to help with the process of hemostatic is the hemostatic material topically oxidized cellulose. This study aims to determine the effect of topical hemostatic administration of oxidized cellulose on blood clotting after extraction of mandibular molars. Material and Methods: This study was an experimental study using 2 sample groups, consisting of 19 patients per group. Results: The results of the study were analyzed using the Independent T Test and Shapiro-Wilk test. The treatment group had a shorter blood coagulum time p=0.0000001 (p<0.05). Conclusion: This shows that there is an effect of giving topical cellulose hemostatic material to blood clotting after tooth extraction.

Abstract

Objective: To determine the effectiveness of green tea on reducing patient’s blood pressure and pulse rate before dental extraction in the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Universitas Sumatera Utara. Material and Methods: This was an experimental quasi study with non-randomized pretest-posttest control group design. Purposive technique was used to select the subjects. The subjects were divided into 2 sample groups, each group consists of 18 patients. The control group were given warm water to drink before the dental extraction while the case group were given steeping green tea before the dental extraction. Blood pressure and pulse rate of each subjects were measured right after informed consent was given. The control group subjects were given to drink warm water while the case group subjects were given green tea steeping after the measurement of blood pressure and pulse rate. After 30 minutes, the blood pressure and pulse rate of each subjects were measured. Data obtained was statistically analyzed using Mann Whitney test and Wilcoxon test. Results: Blood pressure of pulse rate of the case group showed significant differences compared to the control group with a value of p = 0.000 <0.05. Conclusion: Steeping green tea was effective on reducing blood pressure and pulse rate in patients before tooth extraction.

Abstract

Objective: The aim of this study is to determine the effectiveness comparison of ozonated water and povidone iodine 1% on the growth of Streptococcus mutans bacterium (in vitro). Material and Methods: In the act of extracting teeth, complications due to tooth extraction may occur due to various factors and also vary in terms. Infection is one of the complications that can occur after tooth extraction. Streptococcus mutans is a member of the normal flora of the oral cavity, but can become pathogenic if the balance of normal flora disturbed. One alternative way of prophylaxis is to use an antiseptic mouthwash. One commonly used antiseptic is povidone iodine 1%. The use of povidone iodine 1% gargle after tooth extraction, incision and drainage is an effective additional treatment in odontogenic infection. Ozone is one of the most powerful antimicrobial agent available for use in dentistry. Mechanism of ozonated water will only affects the bacteria and does not harm the body's cells because the ozone has anti oxidation. Results: The study were analyzed using the Independent T Test and Shapiro-Wilk test. The result are 0.0001. This value was then compared with 0.05 (p <0.05). This show that there is significant differences in the inhibitory diameter between the ozonated water group and povidone iodine 1% group. Conclusion: This study was an experimental study using 2 sample groups, consisting of 16 samples per group.
