Abstract

Objective: To compare disinfecting effectiveness of 2% glutaraldehyde and 4.8% chloroxylenol on tooth extraction instruments 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 lower molar extraction forceps. In this study, sample were divided into 2 groups and each consisting of 18 instruments. The treatment group was treated with 2% glutaraldehyde while the control group was treated with 4.8% chloroxylenol. Each instrument was pre-cleaned using a brush, water and soap for both groups underwent the disinfection process.Results: The results were statistically analyzed using Mann-Whitney Test. The comparison between glutaraldehyde and chloroxylenol showed a significant difference to the total bacteria count on instrument after disinfection (p=0.014 < 0.05).Conclusion: 2% glutaraldehyde was more effective than 4.8% chloroxylenol at disinfecting lower molar extraction forceps.

Abstract

Objective: Wearing  glove is one form of self protection from blood, saliva and other body fluids secretion exposure or when health worker’s hand in contact with patient’s mucous membrane during treatment/procedure. The type of glove material could affect its ability to prevent bacterial contamination on hand and the most common type of gloves used are nitrile and latex based material.Material and Methods: This is an experimental research with a post-test only design approach. The sampling technique used is Purposive Sampling. In this study, sample were divided into 2 groups consisting of 18 clinical students wearing latex and nitrile gloves while performing dental extraction on either anterior or posterior tooth.Results: The mean results obtained from latex glove are 88.82±168.56 CFU/ml which is higher than the nitrile group 0.00±0.00 CFU/ml. Based on the Mann-Whitney test results, the p value=0.01<0.05 where there are significant difference between latex and nitrile glove.Conclusion: Based on results of research and data analysis, it can be concluded that there are significant differences in the number of bacterial colonies in latex and nitrile gloves where the use of nitrile gloves are more effective than the latex gloves.

Abstract

Objective: To determine the differences in blood pressure of female patients aged 26-45 years with normal Body Mass Index (BMI) and obesity after administration of local anesthetic containing adrenaline before dental extraction in the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Universitas Sumatera Utara.Material and Methods: This was an experimental study with a single group pretest-posttest design. Simple random sampling was used to select the subjects. 32 female patients aged 26-45 years participated in this study. 16 female patients with normal BMI and 16 female patients with obesity visited the clinic for dental extraction in the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, University of North Sumatera. Blood pressure of each subject was measured before and after administration of anesthesia. Data obtained was statistically analyzed using Dependent T-test.Results: Systolic blood pressure between normal and obese subjects after administration of local anesthetic with adrenaline 1:80000 showed significant differences (p<0.05). Diastolic blood pressure between normal and obese subjects after administration of local anesthetic with adrenaline 1:80000 showed no significant differences (p>0.05).Conclusion: Administration of local anesthetic with adrenaline 1: 80000 can increase the blood pressure in obese patients and patients with normal BMI. Obese subjects are more prone to higher diastolic and systolic blood pressure changes compared to subjects with normal BMI.

Abstract

Objective: To determine the effectiveness of gotu kola leaf extract (Centella asiatica (L.) Urban) with a concentration of 1%, 2.5% and 5% as a mouthwash against the growth of Streptococcus mutans bacteria.Materials and Methods: This was a laboratory experimental study with a post-test only control group design. The research sample was Streptococcus mutans bacteria which was bred and cultured in the Microbiology Laboratory of the Universitas Sumatera Utara Hospital. The gotu kola leaves used in the study were extracted and made in the form of mouthwash at the Traditional Medicine Laboratory, Faculty of Pharmacy, Universitas Sumatera Utara. This study used five treatment groups, namely gotu kola leaf extract mouthwash with a concentration of 1%, 2.5%, 5%, Chlorhexidine Gluconate 0.2% (positive control), and DMSO (negative control). The test for five treatment groups was repeated 5 times with Kirby-bauer diffusion method.Results: The results showed that the mouthwash of gotu kola leaf extract (Centella asiatica (L.) Urban) can inhibit the growth of Streptococcus mutans bacteria by forming a clear zone on disc paper. The results were statistically analyzed using Kruskal-wallis and Mann-Whitney Test showed a significant difference in the diameter of the inhibition zone formed in each treatment group (p <0.005).Conclusion: There is effectiveness of gotu kola leaf extract with a concentration of 1%, 2.5% and 5% as a mouthwash in inhibiting the growth of Streptococcus mutans and the most effective concentration was 5%.
