ABSTRACTIntroduction: Heat cured acrylic resin is one of the most widely used denture bases. Patients need to keep the removable denture clean so they don’t adversely affect the patients. Natural ingredients such as soursop leaves (Anonna muricata L.) are known with its benefits so they can be used as a denture cleanser. This research aimed to study the transversal strength of heat cured acrylic resin in immersion of extract Anonna muricata L. effervescent with various concentrations (25%, 35% and 45%). Methods: 24 samples of heat cured acrylic with size of 65mm x 10mm x 2,5mm randomly divided in 4 groups. The control group, the 25%, the 35%, and the 45% immersed in 15 minutes 3 time a day for 10 days. The transversal strength measured by Universal Machine Test (Shimadzu) and analyzed by Kruskal-Wallis. Results: The average transversal strength of the control group showed 118,59 MPa, 25% group showed 114.35 MPa, 35% group showed 117.28 MPa, and 45% showed 111,32 MPa. Based on Kruskal-Wallis, there are no significant differences with a significant value p>0,05 (p=0,886). Conclusion: The highest tranversal strength was found in control group whilst the lowest transversal strength found in group of 45% concentrations. Immersion of heat cured acrylic resin in 25%, 35% and 45% concentration of extract Anonna muricata L. effervescent did not affect the transversal strength of the material.

AbstractIntroduction: Oromaxillofacial traumas comprise injuries to the face, jaws, or both that are largely caused by physical forces, foreign bodies, or burns; they include injury to any of the bony structures, skin, and soft tissues around the face. Maxillofacial trauma is related to human activity or mobility, so traffic accidents are the highest cause. During the Covid-19 pandemic, human activity was mostly at home with movement restrictions. This paper aims to describe the types of characteristics and management of oromaxillofacial traumas during covid-19 pandemic at the emergency room RSUP Dr.Hasan Sadikin Bandung Hospital.Methods: A cross-sectional study was conducted to evaluate every maxillofacial trauma in patients treated by the oral surgeon in the emergency room at RSUP Dr.Hasan Sadikin Bandung Hospital. Maxillofacial trauma incidence records were taken directly from case reports department of oral and maxillofacial surgery emergency room patients from January 2020-December 2021. The variables considered were: patient age, gender, etiologies, sites, classifications, and management of the trauma. All the information found is then integrated into a table to be analyzed epidemiologically. Result: 177 maxillofacial trauma patients were registered in the department of oral and maxillofacial surgery report. It was found that the gender ratio, female to male, is equal to 2.3: 7.6. The 18-36 age group accounted for the largest subgroup in both sexes. Motorcycle accidents accounted for as much as 80.22% of the etiology of the most common traumas. While dentoalveolar (28.22%) was the most common site of the fracture, followed by the mandible (23.31%). Injuries around the mouth make up the most portion (62.15%) regarding the area that is directly impacted by the injuries, followed by injuries to the face (18.64%) and injuries to the mouth and nose combined (6.21%). Among the 177 patients mentioned above, 10.17% were hospitalized.Conclusion: It can be concluded from this cross-sectional study that traffic accidents, mainly motorcycle crashes, are the primary cause of traumas, with males being more prone to accidents. Meanwhile, the dentoalveolar fracture was the most common site of fracture. For this reason, we might be better prepared with all the resources necessary to diagnose and treat patients with oromaxillofacial traumas in the future.
摘要简介：口腔颌面部创伤包括面部、颌骨或两者的损伤，主要由体力、异物或烧伤引起；它们包括对面部周围任何骨骼结构、皮肤和软组织的损伤。颌面部创伤与人类活动或行动能力有关，因此交通事故是最主要的原因。在新冠肺炎大流行期间，人类活动主要在家进行，行动受到限制。本文旨在描述新冠肺炎大流行期间RSUP Hasan Sadikin万隆医院急诊室口腔颌面部创伤的类型、特征和处理。从2020年1月至2021年12月，直接从口腔颌面外科急诊室患者的病例报告部门获取颌面创伤发生率记录。考虑的变量为：患者年龄、性别、病因、部位、分类和创伤管理。然后将所有发现的信息整合到一个表格中，进行流行病学分析。结果：177例颌面部创伤患者在口腔颌面外科登记报告。研究发现，男女性别比例为2.3:7.6。18-36岁年龄组在两性中占最大的亚组。摩托车事故占最常见创伤病因的80.22%。而齿状突（28.22%）是最常见的骨折部位，其次是下颌骨（23.31%）。口腔周围的损伤占直接受损伤区域的大部分（62.15%），其次是面部损伤（18.64%）和口鼻联合损伤（6.21%）。在上述177名患者中，10.17%的患者住院治疗。结论：从这项横断面研究中可以得出结论，交通事故，主要是摩托车碰撞，是造成创伤的主要原因，男性更容易发生事故。同时，齿状突骨折是最常见的骨折部位。因此，我们可能会更好地准备好未来诊断和治疗口腔颌面创伤患者所需的所有资源。

ABSTRACT Introduction: Socket wound would undergo 3 phases of wound-healing process, i.e. inflammation phase, proliferation phase, and re-modelling phase. In proliferation phase, fibroblast cells were important for producing collagen and elastic cells. One of natural ingredients believed to stimulate fibroblasts is Curcuma xanthorriza. The active compounds in curcuma, namely curcumin and flavonoid, had the ability to increase fibroblast migration and accelerate wound healing. This study aims to observe the effectivity of 5% temulawak extract (Curcuma xanthorrhiza) on post-extraction fibroblast cells in Wistar rats (Rattus norvegicus). Methods: The experiment was conducted on 30 rats that were divided into 2 groups, control group and experimental group. Each group of rats were given intermuscular anesthesia and underwent mandibular incisors extraction. The experiment group was given intermuscular injection of 5% curcuma extract into their wound socket, while control group were given placebo gel injection. On day 3, 5, and 7 decapitation was performed to get the mandibular samples. Furthermore, the number of fibroblast cells was observed using a light microscope with 3 different fields of view at 400 times. Results: The results showed that the mean number of fibroblasts in the experiment group was higher than the control group. Conclusion: 5% temulawak extract (Curcuma xanthorrhiza) had significant effect on increasing post-extraction fibroblast cells in Wistar rats (Rattus norvegicus).

Introduction: During covid-19, smartphone can be used as an effective learning media, information center, communication media, and a device to increase students’ knowledge. Many advantages can be obtained by using smartphone during distance learning. However, excessive smartphone use also results in many disadvantages. The students become addicted to the features provided in smartphones. If the user is addicted, then the user will feel anxious if not using the smartphone for too long. This condition is called smartphone addiction. This study was conducted to find characteristic of smartphone use, smartphone addiction percentage, and its percentage according to gender among dental students in University of Sumatera Utara during covid-19. Methods: This study is a descriptive study with the cross-sectional method, using Smartphone Addiction Scale-Short Version (SAS-SV) questionnaire. The questionnaires were distributed using Google forms and then collected and analysed using Microsoft Excel. Total study respondents with the inclusion criteria is 289 respondents (51 male, 238 female). Results: Results showed the most respondents (33,9%) agree that they lost their work plan caused by smartphone use and the least respondents (29,1%) don’t agree that people around them say they use smartphone too often. Most of the respondents (77,9%) are experiencing smartphone addiction (88,2% male, 76,5% female). Conclusion: It was found that the majority of respondents are experiencing smartphone addiction. Further education needed among dental students to know addiction smartphone symptoms earlier and to control smartphone use according to the needs.

AbstractIntroduction: Stainless steel brackets are often used in orthodontic treatment. Chromium is one of the stainless steel bracket elements that increases corrosion resistance. Chromium ions release can cause allergic reactions. Acidic pH due to food and drink consumed can cause corrosion and release of ions. One of the most widely consumed acidic pH drinks is the Lactobacillus casei shirota strain probiotic because it provides health benefits. The purpose of this study was to determine the effect of the Lactobacillus casei shirota strain probiotic beverage on the release of chromium ions in stainless steel brackets. Methods: Laboratory experimental research with post-test only control group design. The number of samples is 10 for 2 groups. The bracket was immersed in artificial saliva as the control group and the probiotic drink Lactobacillus casei shirota strain as the treatment group. After 18 hours and 15 minutes of immersion in an incubator at 37°C, the immersion solutions were tested using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) to determine the release of chromium ions. The results of the study were analyzed using independent t-test. Results: The average chromium ion release in the control group was 7.63 ppm while the treatment group was 7.87 ppm. The results of independent t-test showed a significant difference (p<0.05). Conclusion: The release of chromium ions of stainless steel bracket immersed in probiotic beverage Lactobacillus casei shirota strain was significantly greater than that of immersion in artificial saliva. The value of chromium ion release obtained was still below the average daily intake of chromium.

ABSTRACTIntroduction: Wound healing is a protective function of the body that focuses on quick recovery where the regeneration process in a hostile environment takes more time. In particular, the oral cavity is a remarkable environment in which wound healing occurs in warm oral fluid that contains millions of microorganisms. Collagen plays an important role in all phases of wound healing, which provides integrity and strength to tissues and it is very important especially in the proliferation and remodeling phases. One of the materials that have potential related to collagen is broccoli (Brassica oleracea var.italica). Broccoli has a potential to regulate collagen, therefore it could be an alternative to answer the problem related to antiinflammatory, antioxidant, and antimicrobial effects. The aim of this research with experimental design is to study the potential effects of broccoli extract on the representation of collagen image in wounds.Methods: This research used 18 male wistar rats by making incision on each of the rats’ back. These rats are divided into two groups, control group which get no treatment, and treatment group which is treated by applying the broccoli extract topically twice a day. Wound tissues on each group are observed microscopically on 3th, 7th, and 14th day. The density of collagen fibers was measured based on the calculation of semiquantitative score. Result: The result showed that wound healing on treatment group tends to be better compared with control group with the increase of collagen score of treatment group. The result of Statistical test Man-Whitney with confidence level 95% (p < 0,05) with observation on 3th, 7th, and 14th day sequentally is p=0.100, p=0,100, p=0,700. Conclusion: Broccoli extract which is applied topically tends to have more benefits regarding the process of wound healing, eventhough there is no significant difference found on statitistical test.

In particular, the oral cavity is a remarkable environment in which wound healing occurs in warm oral fluid that contains millions of microorganisms. Collagen plays an important role in all phases of wound healing, which provides integrity and strength to tissues and it is very important especially in the proliferation and remodeling phases. One of the materials that have potential related to collagen is broccoli (Brassica oleracea var.italica). Broccoli has a potential to regulate collagen, therefore it could be an alternative to answer the problem related to antiinflammatory, antioxidant, and antimicrobial effects. The aim of this research with experimental design is to study the potential effects of broccoli extract on the representation of collagen image in wounds.Methods: This research used 18 male wistar rats by making incision on each of the rats’ back. These rats are divided into two groups, control group which get no treatment, and treatment group which is treated by applying the broccoli extract topically twice a day. Wound tissues on each group are observed microscopically on 3th, 7th, and 14th day. The density of collagen fibers was measured based on the calculation of semiquantitative score. Result: The result showed that wound healing on treatment group tends to be better compared with control group with the increase of collagen score of treatment group. The result of Statistical test Man-Whitney with confidence level 95% (p < 0,05) with observation on 3th, 7th, and 14th day sequentally is p=0.100, p=0,100, p=0,700. Conclusion: Broccoli extract which is applied topically tends to have more benefits regarding the process of wound healing, eventhough there is no significant difference found on statitistical test.","PeriodicalId":31757,"journal":{"name":"Padjadjaran Journal of Dentistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42622602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: The common bacteria found in infected root canals are Gram-positive bacteria such as Staphylococcus aureus (20%). S. aureus infection can spread to the periapical tissues causing periapical lesions. Pulp necrosis requires root canal treatment. One of the irrigants used in root canal treatment is 17% ethylenediaminetetraacetic acid (17% EDTA). This material can soften the root canal dentine making it easier to prepare because it can dissolve the inorganic material of smear layer. The disadvantage of 17% EDTA is low antibacterial power, so an alternative irrigation material is needed. Irrigants should ideally be antibacterial. The green okra fruit extract contains antibacterial properties such as alkaloids, flavonoids, saponins, tannins, and terpenoids. This study aims to determine the antibacterial ability of green okra fruit extract concentrations of 12.5%, 25%, 50%, and 100% against S. aureus. Methods: This type of research was an in-vitro laboratory experiment with a posttest-only control group design. The antibacterial test used the disc diffusion method consisted of 6 groups, i.e, green okra fruit extract concentrations of 12.5%, 25%, 50%, 100%, 17% EDTA (positive control), and aquadest (negative control). Antibacterial ability indicated by the clear zone around the disc paper Results: The average diameter of the inhibition zone was green okra fruit extract concentrations of 12.5% (12.14 mm), 25% (14.89 mm), 50% (18.53 mm), 100% (21.1 mm ), 17% EDTA (22.08 mm), and aquadest (0 mm). The results were analyzed with the Mann-Whitney test and showed a significant difference between all research groups (α <0.05). Conclusion: The antibacterial ability of green okra fruit extract (Abelmoschus esculentus) increased from concentrations of 12.5%, 25%, 50%, and 100%, but still lower than the antibacterial ability of 17% EDTA against Staphylococcus aureus.

ABSTRACT Introduction: Dental trauma of the primary teeth is more common in boys than in girls, and it frequently affects the maxillary anterior primary teeth. Approximately 25% of schoolchildren worldwide have had dental trauma, although its prevalence varies among different countries.Group education through public lectures, television, community posters, leaflets, or videos can be selected as an educational method. The ineffective management of trauma to primary teeth is related to a lack of awareness among parents, schoolteachers, and health workers. Dental trauma mostly happens when children are at school; therefore, the study was conducted on Early Childhood Education (ECE) teachers' awareness before and after watching the educational video "Dental Trauma to Primary Teeth". The aim of this study is to determine the influence of the video "Dental Trauma to Primary Teeth” on ECE teachers’ awareness. Methods: This study used an experimental study approach by involving 64 ECE school teachers in Jakarta. They watched the educational movie "Dental Trauma to Primary Teeth" for two minutes before spending ten minutes answering questions to evaluate their understanding of dental trauma in children before and after viewing the film. The questionnaire was divided into 2 parts: the first part consisted of questions about sex, age, and education, and the second part consisted of nine questions about dental trauma to primary teeth. The data were analyzed by comparing understanding before and after watching the educational video. Result: There was an increasing percentage (1.5%-15.6%) after giving the video. The difference between the teacher's degree of awareness before and after watching the educational video "Dental Trauma to Primary Teeth" was statistically significant (p≤0.05) Conclusion: Providing children with educational media in the form of a video titled “Dental Trauma to Primary Teeth” is effective and can increase ECE teachers’ awareness of trauma to primary teeth.Keywords: dental trauma to primary teeth, awareness, educational video

ABSTRACTIntroduction: The biggest problem in oral health is dental caries and periodontal disease. The way to prevent dental and mouth problems is to keep oral hygiene. One of them is adequate plaque control. Plaque control can be done by brushing teeth and using toothpaste. Currently, many herbal ingredients have been used as antibacterials such as gambir (Uncaria gambir). Gambir mainly contains catechins and tannins, which have the ability to inhibit the growth of bacteria. The purpose of this study was to determine the antimicrobial potential of toothpaste containing gambir (Uncaria gambir). Methods: The total sample was 30, and it divided into three groups. Samples were toothpaste containing ten percent of Uncaria gambir extract, fluoride, placebo toothpaste, Streptococcus mutans (Gram-positive), Phorphyromonas gingivalis (Gram-negative), and Candida albicans. Antimicrobial activity of toothpaste with gambir (Uncaria gambir) extract against microorganisms was observed with the formation of inhibitory zone diameter in agar. Data were analyzed by using SPSS with one-way ANOVA and Tukey test. Results: The results showed that toothpaste containing gambir extract could inhibit the Streptococcus mutans (p<0.05), Phorphyromonas gingivalis (p<0.05), Candida albicans (p<0.05) compared significantly with placebo (p<0.05). Antimicrobial toothpaste containing gambir extract had no different effect from toothpaste containing fluoride. However, toothpaste containing gambir extract had significantly different effect than toothpaste containing fluoride. Conclusion: It can be concluded that toothpaste containing gambir (Uncaria gambir) extract has antimicrobial potential against Streptococcus mutans, Phorphyromonas gingivalis, and Candida albicans. These findings showed that the extract of Uncaria gambir possesses potent antimicrobial activity.
