Objective: Tooth extraction in oral surgery can lead to bleeding. Ozone water is a material that is able to accelerate healing process and prevent socket inflammation by stimulating and speeding up the work of cells like fibroblasts. Moreover, ozone water quickens the release of oxygen to the tissue to kill microorganism in tooth socket and accelerate healing process. Material and Methods: This is experimental research using post-test only with control group design. Ozone water is made using DSM Aero High Voltage. The ozonation process takes 30 minutes and followed by soaking a tampon in the ozone water. Patients in the treatment group bite the tampon for 30 minutes while patients in the control group bite a dry tampon. After 30 minutes, the tooth socket is checked to observe the inflammation using the Gingival Score Index. Patients are instructed to come back 7 days after the tooth extraction to check on the inflammation. There is a total of 38 samples in the study and they are divided into 2 groups (treatment and control). This study is conducted in the Department of Oral Surgery and Maxillofacial Faculty of Dentistry USU. Results: The average of Gingival Index after 30 minutes is 0.42±0.507 and 0.95±0.911 for treatment and control groups, respectively. On day 7 the average is 0.00±0.00 for treatment group and 0.37±0.496 for control group. Conclusion: Ozone water is able to stimulate and quicken the healing process for wounds and reduce the inflammation of the tooth socket.
Material and Methods: This was an experimental study with posttest 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.
Staphylococcus aureus is aerobic bacteria that are gram-positive and are one of the normal human flora on the skin and mucous membranes. Most infections in the oral cavity are caused by Staphylococcus aureus, which is a normal flora in the oral cavity that can turn into a pathogen if trauma or abrasion occurs on the mucosal surface. Jengkol peel is thought to contain tannin compounds, which have the potential as an anti-inflammatory, anti-diarrheal, antioxidant, treatment of infections of the skin and mouth, and treatment of burns. This study aimed to explore the potential of jengkol peel extract (Pithecellobium lobatum Benth.) as an antibacterial Staphylococcus aureus regularly in vitro. This study is an experimental research in vitro, where as many as 7 treatment groups were used in this study. Positive and negative controls and extract concentrations of 5%-80% were used as the treatment group. Analysis of the average diameter of the inhibition of bacterial growth was carried out using SPSS version 25 software. The potential inhibition of jengkol peel extract was in line with the increase in the concentration of jengkol peel extract. The higher the concentration of jengkol peel extract, the greater the inhibition of bacterial growth. Extract concentration of 20% has a comparable inhibition of bacterial growth control positive. Jengkol peel extract effectively inhibits the growth of Staphylococcus aureus bacteria. Jengkol peel extract concentration of 20% has effectiveness in inhibiting bacterial growth equivalent to 0.2% chlorhexidine in vitro.
Objective: Disinfection is an act to kill and eliminate all forms of microorganisms including spores with physical or chemical procedures. One of the goals of disinfection in the health sector is to prevent cross infection through microorganisms that are found in blood, saliva and dental plaque that can contaminate the work surface. Material and Methods: This is an experimental research with pretest-posttest design. This study was conducted on 10 dental chair unit and the number of bacterial colonies is observed before and after disinfection using 70% alcohol and 2% glutaraldehyde. Results: The results showed that the number of bacterial colonies experienced a statistically significant decrease after disinfection with 70% alcohol with mean value of 318.20±217.52 before and 11.20±17.29 after disinfection, while 2% glutaraldehyde decreased with mean value before 194.20±206.61 and after disinfection 2.20±2.28. Comparison of the difference in mean number of bacterial colonies between 70% alcohol group and 2% glutaraldehyde group did not show a significant difference (p = 0.412).
Conclusion:Based on the results, it can be concluded that there is no significant difference in the number of bacterial colonies between 70% alcohol and 2% glutaraldehyde. From the results, it can be concluded that there was nothing better in the act of disinfection of dental chair units using 70% alcohol and 2% glutaraldehyde in reducing the number of bacteria.
Background: Cleft lip and palate as a frequent congenital defect is caused by genetic and environmental factors. Micronutrient folic acid as an environmental factor has shown a role as a cleft lip and palate protective factor in several previous studies. Purpose: The purpose of this study was to determine the distribution of adequacy of folic acid supplementation and the association between folic acid supplementation during the first trimester of pregnancy with the incidence of cleft lip and palate at Mitra Sejati Hospital, Medan, North Sumatra, Indonesia. Methods: This study used analytical research with a case-control design and questionnaire. A Chi-square test was used to observe the association between the folic acid supplement intake during the first trimester with the incidence of cleft. The p-value ≤ 0.05 was deemed to be significant. Results: The study found that 47 mothers (51.09%) had insufficient, while 45 mothers (48.91%) had adequate folic acid supplementation. This study did not show a significant association between supplement use and all cleft incidence (p>0.05), but a significant result was found between inadequate supplementation (<400µ/day) and cleft lip with or without cleft palate occurrence (p=0.043; OR 2.4[1.022-5.625]). Conclusion: The present study showed that most pregnant women did not have sufficient folic acid supplement in the first trimester. Furthermore, inadequate maternal folic acid supplementation (<400µ/day) during the first trimester of pregnancy increased the tendency for cleft lip and cleft palate (with or without cleft lip) to occur significantly.

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.
Background: Cleft lip and palate is one of the most common congenital abnormalities in infants and is caused by more than one factors, which can be genetic and environmental. Defects in a family gene can result in cleft lip and palate. The study found a high family history relationship with the incidence of cleft lip and palate. Birth order studied by several researchers also has different results, which were influenced by folic acid consumption, maternal knowledge, lack of antenatal care visits and maternal age. To determine the cases of cleft lip and palate based on the birth order of the children and family history of the patients at Mitra Sejati General Hospital. Purpose: The study aimed to investigate cleft lip and cleft palate patients by birth order and family history. Methods: This research was a retrospective descriptive study using survey method. Researchers gave 13 questions through a questionnaire and data were collected and counted manually. Results: The results showed that based on the birth, the cleft case in the first birth order amounted to 25 people, the second 30 people, the third 19 people, and the fourth or more as many as 20 people. Based on family history, 27 patients had a family history of cleft lip and palate, while 67 patients did not have family history. Conclusion: The cases of clefts at Mitra Sejati General Hospital happened more frequently in the second child and most incidence did not have family history.
